efa97af7e2 fix(agent): add Xiaomi MiMo to reasoning_content echo-back providers
Xiaomi MiMo emits reasoning via OpenAI's reasoning_content field and
requires reasoning_content on every assistant tool-call message when
replaying history. Without echo-back, subsequent API calls fail with
HTTP 400 — same shape as DeepSeek and Kimi/Moonshot thinking modes.

Adds _needs_mimo_tool_reasoning() detection (provider == 'xiaomi',
'mimo' in model, or xiaomimimo.com base url) and wires it into the
_needs_thinking_reasoning_pad() check.

Salvage of #25358 by @ephron-ren (manually re-applied — original branch
was severely stale against current main).

4ceab16893 fix(compression): keep default protect_first_n at 3 + align ABC
Follow-up on the salvaged feat commit:

- Keep the constructor / config / yaml-example default at 3 so existing
  gateway and CLI users see no behavioural change. PR #13754 (which this
  builds on) had lowered the default to 2 to chase pre-feature parity in
  the system-prompt-present case, at the cost of quietly halving the
  protected head for the gateway path (which strips the system prompt
  before calling compress()). With the new "system prompt is implicit"
  semantics, default 3 gives every caller a stable head shape.
- agent/context_engine.py: bring the ABC's protect_first_n docstring in
  line with the new semantics so plugin context engines interpret the
  config key the same way the built-in compressor does.
- tests: adjust the default-value test (3, not 2) and a stale comment;
  per-test protect_first_n=2/3/1 values added in PR #13754 stay as-is
  since those tests fix concrete head shapes.

dee71a31e5 feat(compression): make protect_first_n configurable
The number of head messages preserved verbatim across context compactions
was previously hardcoded to 3 in AIAgent.__init__. Expose it as
`compression.protect_first_n` in config, matching the existing
`protect_last_n` pattern.

Motivation: users who rely on rolling compaction for long-running sessions
had the opening user/assistant exchange pinned as head forever, which
doesn't always match how they want the session framed after many
compactions. Lowering to 1 preserves the system prompt + first non-system
message; lowering to 0 preserves only the system prompt and lets the
entire first exchange age out naturally through the summary.

Semantics: `protect_first_n` counts non-system head messages protected
**in addition to** the system prompt, which is always implicitly protected
when present. Same meaning across both code paths:

  protect_first_n=0 → system prompt only (or nothing if no system message)
  protect_first_n=2 → system prompt + first 2 non-system messages (default)

This unifies the CLI path (which reads messages with the system prompt at
position 0) and the gateway path (where the gateway /compress handler
strips the system prompt before calling compress() — see
gateway/run.py L9150-9154 on the parent fork). Previously these two paths
disagreed:

  CLI path:     protect_first_n=1 → protect system prompt only
  Gateway path: protect_first_n=1 → protect first USER turn forever

In practice on long-running gateway sessions the old semantics pinned
whatever stale aside happened to be the first user message, reinserting
it into every compaction summary indefinitely.

Default chosen as 2 (not 3) so that the effective protected head count
remains 3 messages in the common case — assuming a system prompt is
present, default protection becomes system + 2 non-system = 3 total,
matching the pre-feature behaviour where `protect_first_n` was hardcoded
to protect 3 messages total. Sessions without a system prompt will see a
small behaviour change (2 protected head messages instead of 3), but this
is the rare path and the new semantics make the system-prompt-present
case the well-defined one.

Changes:

- agent/context_compressor.py: redefine protect_first_n as the count of
  non-system head messages protected beyond the implicit system-prompt
  guarantee; both paths converge. Constructor default updated to 2.
- hermes_cli/config.py: add `compression.protect_first_n` default (2),
  matching the new semantics. `show_config` label tweaked to
  'Protect first: N non-system head messages' for clarity.
- run_agent.py: read protect_first_n from config; 0 is now valid (system
  prompt is always implicitly protected).
- cli-config.yaml.example: document the new key and rationale.
- tests/agent/test_context_compressor.py: cover default, override, the
  end-to-end `protect_first_n=0` and `protect_first_n=1` behaviour,
  the no-system-prompt (gateway) path, and the new shared-semantics
  regression test.

Fixes #13751
Tested on Ubuntu 24.04.

07349ce4df fix(memory): pin session_start + session_id on background review fork
Belt-and-suspenders complement to the cached-system-prompt inheritance:
pin session_start and session_id to the parent's so any code path that
re-renders parts of the system prompt (compression, plugin hooks)
still produces byte-identical output. The cached-prompt assignment
already short-circuits the normal rebuild path, but these pins
guarantee parity even if a future code path bypasses the cache.

Idea from simpolism's reference PR #25427 for #25322.

5fe0672260 fix(memory): hit prefix cache in background review fork
Background review fork is supposed to hit Anthropic's prefix cache on the
parent's messages_snapshot, but currently doesn't (cache_read=0 on every
fork). Two root causes, fixed in this commit:

1. System prompt is rebuilt at fork time. _cached_system_prompt starts as
   None, so run_conversation calls _build_system_prompt, which embeds a
   minute-precision "Conversation started: ..." timestamp. Reviews fire
   10+ turns after session start, so the minute differs from main's,
   producing a 1-character diff that invalidates the byte-exact cache key.
   Fix: inherit the parent's _cached_system_prompt directly (same idea as
   #17089, which was self-closed for only fixing this half).

2. Tools schema was narrowed via enabled_toolsets=["memory","skills"] for
   safety. Anthropic's cache key includes `tools`, which sits before
   `system` in the cache hierarchy, so even byte-identical `system` won't
   hit when `tools` differs from main's full set.
   Fix: drop the schema-level restriction so `tools` matches main, and
   deny non-whitelisted tools at runtime via the existing
   get_pre_tool_call_block_message gate (hermes_cli/plugins.py:1085,
   already called at all three dispatch sites). Install/clear a thread-
   local whitelist (added in the previous commit) on the daemon thread.
   Append a soft constraint to the review prompt so the model knows.

Real E2E on Sonnet 4.5 (12-tool task + auto-triggered review):
- Per review-call cost: $0.331 → $0.035 (~89% reduction)
- End-to-end per run:   $0.848 → $0.629 (~26% reduction)
- Review fork cache_create / cache_read: 88,385 / 0  →  1,234 / 94,404

feat(codex-runtime): optional codex app-server runtime for OpenAI/Codex models (#24182)
* feat(codex-runtime): scaffold optional codex app-server runtime

Foundational commit for an opt-in alternate runtime that hands OpenAI/Codex
turns to a 'codex app-server' subprocess instead of Hermes' tool dispatch.
Default behavior is unchanged.

Lands in three pieces:

1. agent/transports/codex_app_server.py — JSON-RPC 2.0 over stdio speaker
   for codex's app-server protocol (codex-rs/app-server). Spawn, init
   handshake, request/response, notification queue, server-initiated
   request queue (for approval round-trips), interrupt-friendly blocking
   reads. Tested against real codex 0.130.0 binary end-to-end during
   development.

2. hermes_cli/runtime_provider.py:
   - Adds 'codex_app_server' to _VALID_API_MODES.
   - Adds _maybe_apply_codex_app_server_runtime() helper, called at the
     end of _resolve_runtime_from_pool_entry(). Inert unless
     'model.openai_runtime: codex_app_server' is set in config.yaml AND
     provider in {openai, openai-codex}. Other providers cannot be
     rerouted (anthropic, openrouter, etc. preserved).

3. tests/agent/transports/test_codex_app_server_runtime.py — 24 tests
   covering api_mode registration, the rewriter helper (default-off,
   case-insensitive, opt-in, non-eligible providers preserved), version
   parser, missing-binary handling, error class. Does NOT require codex
   CLI installed.

This commit is wire-only: the api_mode is recognized but AIAgent does
not yet branch on it. Followup commits add the session adapter, event
projector, approval bridge, transcript projection (so memory/skill
review still works), plugin migration, and slash command.

Existing tests remain green:
- tests/cli/test_cli_provider_resolution.py (29 passed)
- tests/agent/test_credential_pool_routing.py (included above)

* feat(codex-runtime): add codex item projector for memory/skill review

The translator that lets Hermes' self-improvement loop keep working under the
Codex runtime: converts codex 'item/*' notifications into Hermes' standard
{role, content, tool_calls, tool_call_id} message shape that
agent/curator.py already knows how to read.

Item taxonomy (matches codex-rs/app-server-protocol/src/protocol/v2/item.rs):
  - userMessage          → {role: user, content}
  - agentMessage         → {role: assistant, content: text}
  - reasoning            → stashed in next assistant's 'reasoning' field
  - commandExecution     → assistant tool_call(name='exec_command') + tool result
  - fileChange           → assistant tool_call(name='apply_patch') + tool result
  - mcpToolCall          → assistant tool_call(name='mcp.<server>.<tool>') + tool result
  - dynamicToolCall      → assistant tool_call(name=<tool>) + tool result
  - plan/hookPrompt/etc  → opaque assistant note, no fabricated tool_calls

Invariants preserved:
  - Message role alternation never violated: each tool item produces at most
    one assistant + one tool message in that order, correlated by call_id.
  - Streaming deltas (item/<type>/outputDelta, item/agentMessage/delta)
    don't materialize messages — only item/completed does. Mirrors how
    Hermes already only writes the assistant message after streaming ends.
  - Tool call ids are deterministic (codex item id-based) so replays produce
    identical messages and prefix caches stay valid (AGENTS.md pitfall #16).
  - JSON args use sorted_keys for the same reason.

Real wire formats verified against codex 0.130.0 by capturing live
notifications from thread/shellCommand and including one as a fixture
(COMMAND_EXEC_COMPLETED).

23 new tests, all green:
  - Streaming deltas don't materialize (3 paths)
  - Turn/thread frame events are silent
  - commandExecution: 5 tests including non-zero exit annotation +
    deterministic id stability across replays
  - agentMessage + reasoning attachment + reasoning consumption
  - fileChange: summary without inlined content
  - mcpToolCall: namespaced naming + error surfacing
  - userMessage: text fragments only (drops images/etc)
  - opaque items: no fabricated tool_calls
  - Helpers: deterministic id stability + sorted JSON args
  - Role alternation invariant across all four tool-shaped item types

This commit is a pure addition. AIAgent integration (the wire that uses the
projector) is the next commit.

* feat(codex-runtime): add session adapter + approval bridge

The third self-contained module: CodexAppServerSession owns one Codex
thread per Hermes session, drives turn/start, consumes streaming
notifications via CodexEventProjector, handles server-initiated approval
requests, and translates cancellation into turn/interrupt.

The adapter has a single public per-turn method:

    result = session.run_turn(user_input='...', turn_timeout=600)
    # result.final_text          → assistant text for the caller
    # result.projected_messages  → list ready to splice into AIAgent.messages
    # result.tool_iterations     → tick count for _iters_since_skill nudge
    # result.interrupted         → True on Ctrl+C / deadline / interrupt
    # result.error               → error string when the turn cannot complete
    # result.turn_id, thread_id  → for sessions DB / resume

Behavior:

  - ensure_started() spawns codex, does the initialize handshake, and
    issues thread/start with cwd + permissions profile. Idempotent.
  - run_turn() blocks until turn/completed, drains server-initiated
    requests (approvals) before reading notifications so codex never
    deadlocks waiting for us, projects every item/completed via the
    projector, and increments tool_iterations for the skill nudge gate.
  - request_interrupt() is thread-safe (threading.Event); the next loop
    iteration issues turn/interrupt and unwinds.
  - turn_timeout deadlock guard issues turn/interrupt and records an
    error if the turn never completes.
  - close() escalates terminate → kill via the underlying client.

Approval bridge:

  Codex emits server-initiated requests for execCommandApproval and
  applyPatchApproval. The adapter translates Hermes' approval choice
  vocabulary onto codex's decision vocabulary:

    Hermes 'once'                → codex 'approved'
    Hermes 'session' or 'always' → codex 'approvedForSession'
    Hermes 'deny' / anything else → codex 'denied'

  Routing precedence:
    1. _ServerRequestRouting.auto_approve_* flags (cron / non-interactive)
    2. approval_callback wired by the CLI (defers to
       tools.approval.prompt_dangerous_approval())
    3. Fail-closed denial when neither is wired

  Unknown server-request methods are answered with JSON-RPC error -32601
  so codex doesn't hang waiting for us.

Permission profile mapping mirrors AGENTS.md:
    Hermes 'auto'              → codex 'workspace-write'
    Hermes 'approval-required' → codex 'read-only-with-approval'
    Hermes 'unrestricted/yolo' → codex 'full-access'

20 new tests, all green. Combined with prior commits this PR now has
67 tests across three modules:
  - test_codex_app_server_runtime.py: 24 (api_mode + transport surface)
  - test_codex_event_projector.py: 23 (item taxonomy projections)
  - test_codex_app_server_session.py: 20 (turn loop + approvals + interrupts)

Full tests/agent/transports/ directory: 249/249 pass — no regressions
to existing transport tests.

Still no wire into AIAgent.run_conversation(); that integration commit
is small and goes next.

* feat(codex-runtime): wire codex_app_server runtime into AIAgent

The integration commit. AIAgent.run_conversation() now early-returns to a
new helper _run_codex_app_server_turn() when self.api_mode ==
'codex_app_server', bypassing the chat_completions tool loop entirely.

Three small surgical edits to run_agent.py (~105 LOC total):

1. Line ~1204 (constructor api_mode validation set):
   Add 'codex_app_server' so an explicit api_mode='codex_app_server'
   passed to AIAgent() isn't silently rewritten to 'chat_completions'.

2. Line ~12048 (run_conversation, just before the while loop):
   Early-return to _run_codex_app_server_turn() when self.api_mode is
   'codex_app_server'. Placed AFTER all standard pre-loop setup —
   logging context, session DB, surrogate sanitization, _user_turn_count
   and _turns_since_memory increments, _ext_prefetch_cache, memory
   manager on_turn_start — so behavior outside the model-call loop is
   identical between paths. Default Hermes flow is unchanged when the
   flag is off.

3. End-of-class (line ~15497):
   New method _run_codex_app_server_turn(). Lazy-instantiates one
   CodexAppServerSession per AIAgent (reused across turns), runs the
   turn, splices projected_messages into messages, increments
   _iters_since_skill by tool_iterations (since the chat_completions
   loop normally does that per iteration), fires
   _spawn_background_review on the same cadence as the default path.

Counter accounting:

  _turns_since_memory  ← already incremented at run_conversation:11817
                         (gated on memory store configured) — codex
                         helper does NOT touch it (would double-count).
  _user_turn_count     ← already incremented at run_conversation:11793
                         — codex helper does NOT touch it.
  _iters_since_skill   ← incremented in the chat_completions loop per
                         tool iteration. Codex helper increments by
                         turn.tool_iterations since the loop is bypassed.

User message:

  ALREADY appended to messages by run_conversation pre-loop (line 11823)
  before the early-return reaches us. Helper does NOT append again.
  Regression test test_user_message_not_duplicated guards this.

Approval callback wiring:

  Lazy-fetches tools.terminal_tool._get_approval_callback at session
  spawn time, passes to CodexAppServerSession. CLI threads with
  prompt_toolkit get interactive approvals; gateway/cron contexts get
  the codex-side fail-closed deny.

Error path:

  Codex session exceptions become a 'partial' result with completed=False
  and a final_response that explicitly tells the user how to switch back:
  'Codex app-server turn failed: ... Fall back to default runtime with
  /codex-runtime auto.' Same return-dict shape as the chat_completions
  path so all callers (gateway, CLI, batch_runner, ACP) work unchanged.

9 new integration tests in tests/run_agent/test_codex_app_server_integration.py:
  - api_mode='codex_app_server' is accepted on AIAgent construction
  - run_conversation returns the expected codex shape
    (final_response, codex_thread_id, codex_turn_id, completed, partial)
  - Projected messages are spliced into messages list
  - _iters_since_skill ticks per tool iteration
  - _user_turn_count delegated to standard flow (not double-counted)
  - User message appears exactly once (regression guard)
  - _spawn_background_review IS invoked (memory/skill review keeps working)
  - chat.completions.create is NEVER called (loop fully bypassed)
  - Session exception → partial result with /codex-runtime auto hint
  - Interrupted turn → partial result with error preserved

Adjacent test runs confirm no regressions:
  - tests/run_agent/test_memory_nudge_counter_hydration.py: green
  - tests/run_agent/test_background_review.py: green
  - tests/run_agent/test_fallback_model.py: green
  - tests/agent/transports/: 249/249 green

Still missing for full feature: /codex-runtime slash command, plugin
migration helper, docs page, live e2e test gated on codex binary. Those
are the remaining followup commits.

* feat(codex-runtime): add /codex-runtime slash command (CLI + gateway)

User-facing toggle for the optional codex app-server runtime. Follows the
'Adding a Slash Command (All Platforms)' pattern from AGENTS.md exactly:
single CommandDef in the central registry → CLI handler → gateway handler
→ running-agent guard → all surfaces (autocomplete, /help, Telegram menu,
Slack subcommands) update automatically.

Surface:
    /codex-runtime                    — show current state + codex CLI status
    /codex-runtime auto               — Hermes default runtime
    /codex-runtime codex_app_server   — codex subprocess runtime
    /codex-runtime on / off           — synonyms

Files changed:

  hermes_cli/codex_runtime_switch.py (new):
    Pure-Python state machine shared by CLI and gateway. Parse args,
    read/write model.openai_runtime in the config dict, gate enabling
    behind a codex --version check (don't let users opt in to a runtime
    they have no binary for; print npm install hint instead).
    Returns a CodexRuntimeStatus dataclass that callers render however
    suits their surface.

  hermes_cli/commands.py:
    Single CommandDef entry, no aliases (codex-runtime is its own thing).

  cli.py:
    Dispatch in process_command() + _handle_codex_runtime() handler that
    delegates to the shared module and renders results via _cprint.

  gateway/run.py:
    Dispatch in _handle_message() + _handle_codex_runtime_command() that
    returns a string (gateway sends as message). On a successful change
    that requires a new session, _evict_cached_agent() forces the next
    inbound message to construct a fresh AIAgent with the new api_mode —
    avoids prompt-cache invalidation mid-session.

  gateway/run.py running-agent guard:
    /codex-runtime joins /model in the early-intercept block so a runtime
    flip mid-turn can't split a turn across two transports.

Tests:
  tests/hermes_cli/test_codex_runtime_switch.py — 25 tests covering the
  state machine: arg parsing (10 cases incl. case-insensitive and
  synonyms), reading current runtime (5 cases incl. malformed configs),
  writing runtime (3 cases), apply() entry point covering read-only,
  no-op, codex-missing-blocked, codex-present-success, disable-no-binary-check,
  and persist-failure paths (8 cases). All green.

Adjacent test suites confirm no regressions:
  - tests/hermes_cli/test_commands.py + test_codex_runtime_switch.py:
    167/167 green
  - tests/agent/transports/: 283/283 green when combined with prior commits

Still missing: plugin migration helper, docs page, live e2e test gated on
codex binary. Followup commits.

* feat(codex-runtime): auto-migrate Hermes MCP servers to ~/.codex/config.toml

Translates the user's mcp_servers config from ~/.hermes/config.yaml into
the TOML format codex's MCP client expects. Wired into the
/codex-runtime codex_app_server enable path so users get their MCP tool
surface in the spawned subprocess automatically.

The migration runs on every enable. Failures are non-fatal — the runtime
change still proceeds and the user gets a warning so they can fix the
codex config manually.

What translates (mapping verified against codex-rs/core/src/config/edit.rs):
  Hermes mcp_servers.<n>.command/args/env  → codex stdio transport
  Hermes mcp_servers.<n>.url/headers       → codex streamable_http transport
  Hermes mcp_servers.<n>.timeout           → codex tool_timeout_sec
  Hermes mcp_servers.<n>.connect_timeout   → codex startup_timeout_sec
  Hermes mcp_servers.<n>.cwd               → codex stdio cwd
  Hermes mcp_servers.<n>.enabled: false    → codex enabled = false

What does NOT translate (warned + skipped per server):
  Hermes-specific keys (sampling, etc.) — codex's MCP client has no
  equivalent. Listed in the per-server skipped[] field of the report.

What's NOT migrated (intentional):
  AGENTS.md — codex respects this file natively in its cwd. Hermes' own
  AGENTS.md (project-level) is already in the worktree, so codex picks
  it up without translation. No code needed.

Idempotency design:
  All managed content lives between a 'managed by hermes-agent' marker
  and the next non-mcp_servers section header. _strip_existing_managed_block
  removes the prior managed region cleanly, preserving any user-added
  codex config (model, providers.openai, sandbox profiles, etc.) above
  or below.

Files added:
  hermes_cli/codex_runtime_plugin_migration.py — pure-Python migration
    helper. Public API: migrate(hermes_config, codex_home=None,
    dry_run=False) returns MigrationReport with .migrated/.errors/
    .skipped_keys_per_server. No external TOML dependency — minimal
    formatter handles strings/numbers/booleans/lists/inline-tables.

  tests/hermes_cli/test_codex_runtime_plugin_migration.py — 39 tests
  covering:
    - per-server translation (12): stdio/http/sse, cwd, timeouts,
      enabled flag, command+url precedence, sampling drop, unknown keys
    - TOML formatter (8): types, escaping, inline tables, error case
    - existing-block stripping (4): no marker, alone, with user content
      above, with user content below
    - end-to-end migrate() (8): empty, dry-run, round-trip, idempotent
      re-run, preserves user config, error reporting, invalid input,
      summary formatting

Files changed:
  hermes_cli/codex_runtime_switch.py — apply() now calls migrate() in
    the codex_app_server enable branch. Migration failure logs a warning
    in the result message but does NOT fail the runtime change. Disable
    path (auto) explicitly skips migration.

  tests/hermes_cli/test_codex_runtime_switch.py — 3 new tests:
    test_enable_triggers_mcp_migration, test_disable_does_not_trigger_migration,
    test_migration_failure_does_not_block_enable.

All 325 feature tests green:
  - tests/agent/transports/: 249 (incl. 67 new)
  - tests/run_agent/test_codex_app_server_integration.py: 9
  - tests/hermes_cli/test_codex_runtime_switch.py: 28 (3 new)
  - tests/hermes_cli/test_codex_runtime_plugin_migration.py: 39 (new)

* perf(codex-runtime): cache codex --version check within apply()

Single /codex-runtime invocation could spawn 'codex --version' up to 3
times (state report, enable gate, success message). Each spawn is ~50ms,
so the cumulative cost wasn't a crisis, but it was wasteful and turned a
trivial slash command into something noticeably laggy on slower systems.

Refactored to lazy-once via a closure over a nonlocal cache. First call
spawns; subsequent calls in the same apply() reuse the result.

Behavior unchanged — same return shape, same error handling, same install
hint when codex is missing. Just one subprocess per call instead of three.

Two regression-guard tests added:
  - test_binary_check_cached_within_apply: enable path → call_count == 1
  - test_binary_check_cached_on_read_only_call: state-report path → call_count == 1

Total tests for /codex-runtime now 30 (was 28); all 143 codex-runtime
tests still green.

* fix(codex-runtime): correct protocol field names found via live e2e test

Three real bugs caught only by running a turn end-to-end against codex
0.130.0 with a real ChatGPT subscription. Unit tests passed because they
asserted on our own (incorrect) wire shapes; the wire format from
codex-rs/app-server-protocol/src/protocol/v2/* is the source of truth and
my initial reading of the README was incomplete.

Bug 1: thread/start.permissions wire format

Was sending {"profileId": "workspace-write"}.
Real format per PermissionProfileSelectionParams enum (tagged union):
  {"type": "profile", "id": "workspace-write"}
AND requires the experimentalApi capability declared during initialize.
AND requires a matching [permissions] table in ~/.codex/config.toml or
codex fails the request with 'default_permissions requires a [permissions]
table'.

Fix: stop overriding permissions on thread/start. Codex picks its default
profile (read-only unless user configures otherwise), which matches what
codex CLI users expect — they configure their default permission profile
in ~/.codex/config.toml the standard way. Trying to be clever about
profile selection broke every turn we tested.

Live error before fix: 'Invalid request: missing field type' on every
turn/start, even though our turn/start payload was correct — the field
codex was complaining about was inside the permissions sub-object we
shouldn't have been sending.

Bug 2: server-request method names

Was matching 'execCommandApproval' and 'applyPatchApproval'.
Real names per common.rs ServerRequest enum:
  item/commandExecution/requestApproval
  item/fileChange/requestApproval
  item/permissions/requestApproval (new third method)

Fix: match the documented names. Added handler for
item/permissions/requestApproval that always declines — codex sometimes
asks to escalate permissions mid-turn and silent acceptance would surprise
users.

Live symptom before fix: agent.log showed
'Unknown codex server request: item/commandExecution/requestApproval'
and codex stalled because we replied with -32601 (unsupported method)
instead of an approval decision. The agent reported back 'The write
command was rejected' even though Hermes never showed the user an
approval prompt.

Bug 3: approval decision values

Was sending decision strings 'approved'/'approvedForSession'/'denied'.
Real values per CommandExecutionApprovalDecision enum (camelCase):
  accept, acceptForSession, decline, cancel
(also AcceptWithExecpolicyAmendment and ApplyNetworkPolicyAmendment
variants we don't currently use).

Fix: rename _approval_choice_to_codex_decision return values; update
auto_approve_* fallbacks; update fail-closed default from 'denied' to
'decline'. Test mapping table updated to match.

Live test verified after fixes:
  $ hermes (with model.openai_runtime: codex_app_server)
  > Run the shell command: echo hermes-codex-livetest > .../proof.txt
    then read it back

  Approval prompt fired with 'Codex requests exec in <cwd>'.
  User chose 'Allow once'. Codex executed the command, wrote the file,
  read it back. Final response: 'Read back from proof.txt:
  hermes-codex-livetest'. File contents on disk match.

agent.log confirms:
  codex app-server thread started: id=019e200e profile=workspace-write
                                    cwd=/tmp/hermes-codex-livetest/workspace

All 20 session tests still green after wire-format updates.

* fix(codex-runtime): correct apply_patch approval params + ship docs

Live e2e revealed FileChangeRequestApprovalParams doesn't carry the
changeset (just itemId, threadId, turnId, reason, grantRoot) — Codex's
'reason' field describes what the patch wants to do. Test config and
display logic updated to use it. The first 'apply_patch (0 change(s))'
display from the live test is now 'apply_patch: <reason>'.

Adds website/docs/user-guide/features/codex-app-server-runtime.md
covering enable/disable, prerequisites, approval UX, MCP migration
behavior, permission profile delegation to ~/.codex/config.toml, known
limitations, and the architecture diagram. Wired into the Automation
category in sidebars.ts.

Live e2e validation across the path matrix:
  ✓ thread/start handshake
  ✓ turn/start with text input
  ✓ commandExecution items + projection
  ✓ item/commandExecution/requestApproval → Hermes UI → response
  ✓ Approve once → command runs
  ✓ Deny → command rejected, codex falls back to read-only message
  ✓ Multi-turn (codex remembers prior turn's results)
  ✓ apply_patch via Codex's fileChange path
  ✓ item/fileChange/requestApproval → Hermes UI
  ✓ MCP server migration loads inside spawned codex (verified via
    'use the filesystem MCP tool' prompt)
  ✓ /codex-runtime auto → codex_app_server toggle cycle
  ✓ Disable doesn't trigger migration
  ✓ Enable with codex CLI present succeeds + migrates
  ✓ Hermes-side interrupt path (turn/interrupt request issued cleanly
    even if codex finishes before the interrupt lands)

Known live-validated limitations now documented in the docs page:
  - delegate_task subagents unavailable on this runtime
  - permission profile selection delegated to ~/.codex/config.toml
  - apply_patch approval prompt has no inline changeset (codex protocol
    doesn't expose it)

145/145 codex-runtime tests still green.

* feat(codex-runtime): native plugin migration + UX polish (quirks 2/4/5/10/11)

Major: migrate native Codex plugins (#7 in OpenClaw's PR list)

Discovers installed curated plugins via codex's plugin/list RPC and
writes [plugins."<name>@<marketplace>"] entries to ~/.codex/config.toml
so they're enabled in the spawned Codex sessions. This is the
'YouTube-video-worthy' bit Pash highlighted: when a user has
google-calendar, github, etc. installed in their Codex CLI, those
plugins activate automatically when they enable Hermes' codex runtime.

Implementation:
  - hermes_cli/codex_runtime_plugin_migration.py: new _query_codex_plugins()
    helper spawns 'codex app-server' briefly and walks plugin/list. Returns
    (plugins, error) — failures are non-fatal so MCP migration still works.
  - render_codex_toml_section() now takes plugins + permissions args.
  - migrate() defaults: discover_plugins=True, default_permission_profile=
    'workspace-write'. Explicit None on either disables that side.
  - _strip_existing_managed_block() now also strips [plugins.*] and
    [permissions]/[permissions.*] sections inside the managed block, so
    re-runs replace plugins cleanly without touching codex's own config.

Quirk fixes:

#2 Default permissions profile written on enable.
   Without this, Codex's read-only default kicks in and EVERY write
   triggers an approval prompt. Now writes [permissions] default =
   'workspace-write' so the runtime feels normal out of the box. Set
   default_permission_profile=None to opt out.

#4 apply_patch approval prompt now shows what's changing.
   Codex's FileChangeRequestApprovalParams doesn't carry the changeset.
   Session adapter now caches the fileChange item from item/started
   notifications and looks it up by itemId when codex requests approval.
   Prompt shows '1 add, 1 update: /tmp/new.py, /tmp/old.py' instead of
   'apply_patch (0 change(s))'.

   Side benefit: also drains pending notifications BEFORE handling a
   server request, so the projector and per-turn caches are up to date
   when the approval decision fires. Bounded to 8 notifications per
   loop iter to avoid starving codex's response.

#5/#10 Exec approval prompt never shows empty cwd.
   When codex omits cwd in CommandExecutionRequestApprovalParams, fall
   back to the session's cwd. If somehow neither is available, show
   '<unknown>' explicitly instead of an empty string.

   Also surfaces 'reason' from the approval params when codex provides
   it — gives users more context on why codex wants to run something.

#11 Banner indicates the codex_app_server runtime when active.
   New 'Runtime: codex app-server (terminal/file ops/MCP run inside
   codex)' line appears in the welcome banner only when the runtime is
   on. Default banner is unchanged.

Tests:
  - 7 new tests in test_codex_runtime_plugin_migration.py covering
    plugin discovery (mocked), failure handling, dry-run skip, opt-out
    flag, idempotent re-runs, and permissions writing.
  - 3 new tests in test_codex_app_server_session.py covering the
    enriched approval prompts: cwd fallback, change summary on
    apply_patch, fallback when no item/started cache exists.
  - All 26 session tests + 46 migration tests green; 153 total in PR.

* feat(codex-runtime): hermes-tools MCP callback + native plugin migration

The big architectural addition: when codex_app_server runtime is on,
Hermes registers its own tool surface as an MCP server in
~/.codex/config.toml so the codex subprocess can call back into Hermes
for tools codex doesn't ship with — web_search, browser_*, vision,
image_generate, skills, TTS.

Also: 'migrate native codex plugins' (Pash's YouTube-video-worthy bit) —
when the user has plugins like Linear, GitHub, Gmail, Calendar, Canva
installed via 'codex plugin', Hermes discovers them via plugin/list and
writes [plugins.<name>@openai-curated] entries so they activate
automatically.

New module: agent/transports/hermes_tools_mcp_server.py
  FastMCP stdio server exposing 17 Hermes tools. Each call dispatches
  through model_tools.handle_function_call() — same code path as the
  Hermes default runtime. Run with:
    python -m agent.transports.hermes_tools_mcp_server [--verbose]

  Exposed: web_search, web_extract, browser_navigate / _click / _type /
    _press / _snapshot / _scroll / _back / _get_images / _console /
    _vision, vision_analyze, image_generate, skill_view, skills_list,
    text_to_speech.

  NOT exposed (deliberately):
    - terminal/shell/read_file/write_file/patch — codex has built-ins
    - delegate_task/memory/session_search/todo — _AGENT_LOOP_TOOLS in
      model_tools.py:493, require running AIAgent context. Documented
      as a limitation and surfaced in the slash command output.

Migration changes (hermes_cli/codex_runtime_plugin_migration.py):
  - _query_codex_plugins() spawns 'codex app-server' briefly to walk
    plugin/list and pull installed openai-curated plugins. Failures are
    non-fatal — MCP migration still completes.
  - render_codex_toml_section() now takes plugins + permissions args
    AND wraps the managed block with a MIGRATION_END_MARKER comment so
    the stripper can reliably find both ends, even when the block
    contains top-level keys (default_permissions = ...).
  - migrate() defaults: discover_plugins=True, expose_hermes_tools=True,
    default_permission_profile=':workspace' (built-in codex profile name
    — must be prefixed with ':'). All three opt-out via explicit args.
  - _build_hermes_tools_mcp_entry() builds the codex stdio entry with
    HERMES_HOME and PYTHONPATH passthrough so a worktree-launched
    Hermes points the MCP subprocess at the same module layout.

Live-caught wire bugs fixed during this turn:
  1. Permission profile config key is top-level , NOT a [permissions] table. The [permissions] table is
     for *user-defined* profiles with structured fields. Built-in
     profile names start with ':' (':workspace', ':read-only',
     ':danger-no-sandbox'). Was emitting
     which codex rejected with 'invalid type: string "X", expected
     struct PermissionProfileToml'.
  2. Built-in profile is , NOT . Codex
     rejected  with 'unknown built-in profile'.
  3. Codex's MCP layer sends  for
     tool-call confirmation. We weren't handling it, so codex stalled
     and returned 'MCP tool call was rejected'. Now: auto-accept for
     our own hermes-tools server (user already opted in by enabling
     the runtime), decline for third-party servers.

Quirk fixes shipped (from the limitations list):
  #2 default permissions: workspace profile written on enable. No more
     approval prompt on every write.
  #4 apply_patch approval shows what's changing: cache fileChange
     items from item/started, look up by itemId when codex sends
     item/fileChange/requestApproval. Prompt: '1 add, 1 update:
     /tmp/new.py, /tmp/old.py' instead of '0 change(s)'.
  #5/#10 exec approval cwd never empty: fall back to session cwd, then
     '<unknown>'. Also surfaces 'reason' from codex when present.
  #11 banner shows 'Runtime: codex app-server' line when active so
     users understand why tool counts may not match what's reachable.

Tests:
  - 5 new tests in test_codex_runtime_plugin_migration.py covering
    plugin discovery, expose_hermes_tools entry generation, idempotent
    re-runs, opt-out flag, permissions profile.
  - 3 new tests in test_codex_app_server_session.py covering enriched
    approval prompts (cwd fallback, fileChange summary).
  - 2 new tests for mcpServer/elicitation/request handling (accept
    hermes-tools, decline others).
  - New test file test_hermes_tools_mcp_server.py covering module
    surface, EXPOSED_TOOLS safety invariants (no shell/file_ops,
    no agent-loop tools), and main() error paths.
  - 166 codex-runtime tests total, all green.

Live e2e validated against codex 0.130.0 + ChatGPT subscription:
  ✓ /codex-runtime codex_app_server enables, migrates filesystem MCP,
    registers hermes-tools, writes default_permissions = ':workspace'
  ✓ Banner shows 'Runtime: codex app-server' line in subsequent sessions
  ✓ Shell command runs without approval prompt (workspace profile works)
  ✓ Multi-turn — codex remembers prior turn's results
  ✓ apply_patch path via fileChange request approval
  ✓ web_search via hermes-tools MCP callback returns real Firecrawl
    results: 'OpenAI Codex CLI – Getting Started' end-to-end in 13s
  ✓ Disable cycle clean

Docs updated: website/docs/user-guide/features/codex-app-server-runtime.md
  Full re-write covering native plugin migration, the hermes-tools
  callback architecture, the prerequisites change ('codex login is
  separate from hermes auth login codex'), the trade-off table now
  reflecting which Hermes tools work via callback, and the limitations
  list updated with what's actually unavailable on this runtime.

* feat(codex-runtime): pin user-config preservation invariant for quirk #6

Quirk #6 from the limitations list — user MCP servers / overrides /
codex-only sections in ~/.codex/config.toml that live OUTSIDE the
hermes-managed block must survive re-migration verbatim.

This already worked thanks to the MIGRATION_MARKER + MIGRATION_END_MARKER
pair I added when fixing the default_permissions wire format (so the
strip can find both ends of the managed region even with top-level
keys like default_permissions). But it was an emergent property
without a test pinning it.

Now explicitly tested:
  - User MCP server above the managed block survives migration
  - User MCP server below the managed block survives migration
  - Both above + below survive a second re-migration
  - User content (model, providers, sandbox, otel, etc.) outside our
    region is left untouched

Docs added a section "Editing ~/.codex/config.toml safely" explaining
the marker contract — so users know they can add their own MCP
servers, override permissions, configure codex-only options, etc.
without fear of Hermes overwriting their work.

167 codex-runtime tests, all green.

* docs(codex-runtime): clarify the actual tool surface — shell covers terminal/read/write/find

Previous docs and PR description undersold what codex's built-in
toolset actually provides. apply_patch alone made it sound like the
runtime could only edit files in patch format — implying you'd lose
terminal use, read_file, write_file, search/find. That was wrong.

Codex's 'shell' tool runs arbitrary shell commands inside the sandbox,
which covers everything you'd do in bash: cat/head/tail (read), echo>
or heredocs (write), find/rg/grep (search), ls/cd (navigate), build/
test/git/etc. apply_patch is for structured multi-file edits on top
of that. update_plan is its in-runtime todo. view_image loads images.
And codex has its own web_search built in (in addition to the
Firecrawl-backed one Hermes exposes via MCP callback).

Docs now have a 'What tools the model actually has' section right
after Why, breaking the surface into three clearly-labeled buckets:

  1. Codex's built-in toolset (always on) — shell, apply_patch,
     update_plan, view_image, web_search; covers everything terminal-
     adjacent.
  2. Native Codex plugins (auto-migrated from your codex plugin
     install) — Linear, GitHub, Gmail, Calendar, Outlook, Canva, etc.
  3. Hermes tool callback (MCP server in ~/.codex/config.toml) —
     web_search/web_extract via Firecrawl, browser_*, vision_analyze,
     image_generate, skill_view/skills_list, text_to_speech.

Plus a 'What's NOT available' callout listing the four agent-loop tools
(delegate_task, memory, session_search, todo) that need running
AIAgent context and can't reach the codex runtime.

Trade-offs table broken out: shell, apply_patch, update_plan,
view_image, sandbox each get their own row with a one-line description
so users can see at a glance what's available natively.

Architecture diagram updated to list the codex built-ins by name
instead of 'apply_patch + shell + sandbox'.

No code changes — purely docs clarification. 167 codex-runtime tests
still green.

* fix(codex-runtime): _spawn_background_review signature + review fork api_mode downgrade

Two real bugs in the self-improvement loop integration that the previous
test mocked away.

Bug 1: wrong call signature

The codex helper was calling self._spawn_background_review() with no
args after every turn. That function actually requires:
  messages_snapshot=list   (positional or keyword)
  review_memory=bool       (at least one trigger must be True)
  review_skills=bool

So the call would have raised TypeError at runtime — except the only
test that exercised this path mocked _spawn_background_review entirely
and just asserted spawn.called, so the wrong-arg shape never surfaced.

Bug 2: review fork inherits codex_app_server api_mode

The review fork is constructed with:
  api_mode = _parent_runtime.get('api_mode')

So when the parent is codex_app_server, the review fork ALSO runs as
codex_app_server. But the review fork's whole job is to call agent-loop
tools (memory, skill_manage) which require Hermes' own dispatch — they
short-circuit with 'must be handled by the agent loop' on the codex
runtime. So the review fork would have run, decided to save something,
called memory or skill_manage, and silently no-op'd.

Fixed in run_agent.py:_spawn_background_review() — when the parent
api_mode is 'codex_app_server', the review fork is downgraded to
'codex_responses' (same OAuth credentials, same openai-codex provider,
but talks to OpenAI's Responses API directly so Hermes owns the loop).

Also rewrote the codex helper's review wiring to match the
chat_completions path:
  - Computes _should_review_memory in the pre-loop block (was already
    being computed; now passed through to the helper as an arg).
  - Computes _should_review_skills AFTER the codex turn returns +
    counters tick (line ~15432 pattern in chat_completions).
  - Calls _spawn_background_review(messages_snapshot=, review_memory=,
    review_skills=) only when at least one trigger fires.
  - Adds the external memory provider sync (_sync_external_memory_for_turn)
    that the chat_completions path runs after every turn.

Tests:

  Replaced the broken test_background_review_invoked (which only
  asserted spawn.called) with three sharper tests:
    - test_background_review_NOT_invoked_below_threshold:
      single turn at default thresholds → no review fires (would have
      caught the original 'every turn calls spawn with no args' bug)
    - test_background_review_skill_trigger_fires_above_threshold:
      10 tool_iterations at threshold=10 → review fires with
      messages_snapshot=list, review_skills=True, counter resets
    - test_background_review_signature_never_breaks: regression guard
      asserting positional args are always empty and kwargs include
      messages_snapshot

  New TestReviewForkApiModeDowngrade class:
    - test_codex_app_server_parent_downgrades_review_fork: drives the
      real _spawn_background_review function (no mock at that level),
      asserts the review_agent gets api_mode='codex_responses' when
      the parent was codex_app_server.

Live-validated against real run_conversation:
  - Counter ticked from 0 to 5 after a 5-tool-iteration turn
  - _spawn_background_review fired exactly once with kwargs-only signature
  - review_skills=True, review_memory=False
  - messages_snapshot was 12 entries (5 assistant tool_calls + 5 tool
    results + 1 final assistant + initial system/user)
  - Counter reset to 0 after fire

170 codex-runtime tests, all green.

Docs: added a Self-improvement loop section to the codex runtime page
explaining both how the trigger logic stays equivalent and that the
review fork is auto-downgraded to codex_responses for the agent-loop
tools. Also clarified that apply_patch and update_plan ARE codex's
built-in tools (the previous version made it sound like they were
separate from 'codex's stuff' — they're not, all five tools listed
in 'What tools the model actually has' section 1 are codex built-ins).

* feat(codex-runtime): expose kanban tools through Hermes MCP callback

Kanban workers spawn as separate hermes chat -q subprocesses that read
the user's config.yaml. If model.openai_runtime: codex_app_server is set
globally (which is the whole point of opt-in), every dispatched worker
ALSO comes up on the codex runtime.

That mostly works — codex's built-in shell + apply_patch + update_plan
do the actual task work fine — but it had one critical break: the
worker handoff tools (kanban_complete, kanban_block, kanban_comment,
kanban_heartbeat) are Hermes-registered tools, not codex built-ins.
On the codex runtime, codex builds its own tool list and these never
reach the model, so the worker would do the work but not be able to
report back, hanging until the dispatcher's timeout escalates it as
zombie.

Fix: add all 9 kanban tools to the EXPOSED_TOOLS list in the Hermes
MCP callback. They dispatch statelessly through handle_function_call()
just like web_search and the others — they read HERMES_KANBAN_TASK
from env (set by the dispatcher), gate correctly (worker tools require
the env var, orchestrator tools require it unset), and write to
~/.hermes/kanban.db.

Why kanban tools work via stateless dispatch when delegate_task/memory/
session_search/todo don't: those four are listed in _AGENT_LOOP_TOOLS
(model_tools.py:493) and short-circuit in handle_function_call() with
'must be handled by the agent loop' — they need to mutate AIAgent's
mid-loop state. Kanban tools have no such requirement; they're pure
side-effect functions against the kanban.db plus state_meta.

Tools exposed:
  Worker handoff (require HERMES_KANBAN_TASK):
    kanban_complete, kanban_block, kanban_comment, kanban_heartbeat
  Read-only board queries:
    kanban_show, kanban_list
  Orchestrator (require HERMES_KANBAN_TASK unset):
    kanban_create, kanban_unblock, kanban_link

Tests:
  - test_kanban_worker_tools_exposed: complete/block/comment/heartbeat
    in EXPOSED_TOOLS (regression guard for the would-hang-worker bug)
  - test_kanban_orchestrator_tools_exposed: create/show/list/unblock/link

Docs:
  - New 'Workflow features' section in the docs page covering /goal,
    kanban, and cron behavior on this runtime
  - /goal: works fully via run_conversation feedback; only caveat is
    approval-prompt noise on long writes-heavy goals (mitigated by
    the default :workspace permission profile)
  - Kanban: enumerated which tools are reachable via the callback and
    why the env var propagates correctly through the codex subprocess
    to the MCP server subprocess
  - Cron: documented as 'not specifically tested' — same rules as the
    CLI apply since cron runs through AIAgent.run_conversation
  - Trade-offs table gained rows for /goal, kanban worker, kanban
    orchestrator

172/172 codex-runtime tests green (+2 from kanban tests).

* docs(codex-runtime): wire /codex-runtime into slash-commands ref + flag aux token cost

Three docs gaps caught during a final audit:

1. /codex-runtime was only in the feature docs page, not in the
   slash-commands reference. Added rows to both the CLI section and
   the Messaging section so users discover it where they'd look for
   slash command syntax.

2. CODEX_HOME and HERMES_KANBAN_TASK weren't in environment-variables.md.
   CODEX_HOME lets users redirect Codex CLI's config dir (the migration
   honors it). HERMES_KANBAN_TASK is set by the kanban dispatcher and
   propagates to the codex subprocess + the hermes-tools MCP subprocess
   so kanban worker tools gate correctly — documented as 'don't set
   manually' since it's an internal handoff.

3. Aux client behavior on this runtime. When openai_runtime=
   codex_app_server is on with the openai-codex provider, every aux
   task (title generation, context compression, vision auto-detect,
   session search summarization, the background self-improvement review
   fork) flows through the user's ChatGPT subscription by default.

   This is true for the existing codex_responses path too, but it's
   more visible / important here because users explicitly opted in for
   subscription billing. Added a 'Auxiliary tasks and ChatGPT
   subscription token cost' section to the docs page with a YAML
   example showing how to override specific aux tasks to a cheaper
   model (typically google/gemini-3-flash-preview via OpenRouter).

   Also documents how the self-improvement review fork gets
   auto-downgraded from codex_app_server to codex_responses by the
   fix earlier in this PR.

No code changes — pure docs. 172 codex-runtime tests still green.

* docs+test(codex-runtime): pin HOME passthrough, document multi-profile + CODEX_HOME

OpenClaw hit a real footgun in openclaw/openclaw#81562: when spawning
codex app-server they were synthesizing a per-agent HOME alongside
CODEX_HOME. That made every subprocess codex's shell tool launches
(gh, git, aws, npm, gcloud, ...) see a fake $HOME and miss the user's
real config files. They had to back it out in PR #81562 — keep
CODEX_HOME isolation, leave HOME alone.

Audit confirms Hermes' codex spawn doesn't have this problem. We do
os.environ.copy() and only overlay CODEX_HOME (when provided) and
RUST_LOG. HOME passes through unchanged. But it was an emergent
property without a test pinning it, so adding a regression guard:

  test_spawn_env_preserves_HOME — confirms parent HOME survives intact
                                  in the subprocess env
  test_spawn_env_sets_CODEX_HOME_when_provided — confirms codex_home
                                                  arg still isolates
                                                  codex state correctly

Docs additions:

  'HOME environment variable passthrough' section — calls out the
  contract explicitly: CODEX_HOME isolates codex's own state, HOME
  stays user-real so gh/git/aws/npm/etc. find their normal config.
  Cites openclaw#81562 as the cautionary tale.

  'Multi-profile / multi-tenant setups' section — addresses the
  related concern: profiles share ~/.codex/ by default. For users who
  want per-profile codex isolation (separate auth, separate plugins),
  documents the manual CODEX_HOME=<profile-scoped-dir> approach.

  Explains why we DON'T auto-scope CODEX_HOME per profile: doing so
  would silently invalidate existing codex login state for anyone
  upgrading to this PR with tokens already at ~/.codex/auth.json.
  Opt-in is safer than surprising users.

174 codex-runtime tests (+2 from HOME guards), all green.

* fix(codex-runtime): TOML control-char escapes + atomic config.toml write

Two footguns caught in a final audit pass before merge.

Bug 1: TOML control characters not escaped

The _format_toml_value() helper escaped backslashes and double quotes
but passed literal control characters (\n, \t, \r, \f, \b) through
unchanged. TOML basic strings don't allow literal control characters
— a path or env var containing a newline would produce invalid TOML
that codex refuses to load.

Realistic exposure: pathological cases like a HERMES_HOME with a
trailing newline (env var concatenation accident), or a PYTHONPATH
with a tab from a multi-line shell heredoc.

Fix: escape all five TOML basic-string control sequences (\b \t \n
\f \r) in addition to \\ and \" that we already did. Order
matters — backslash must come first or the other escapes get
re-escaped.

Bug 2: config.toml write wasn't atomic

If the python process crashed between target.mkdir() and the
write_text() finishing, a half-written config.toml could be left
behind. On NFS / Windows / some FUSE mounts this is a real concern;
on ext4/APFS small writes are usually atomic in practice but not
guaranteed.

Fix: write to a tempfile.mkstemp() temp file in the same directory,
then Path.replace() (atomic same-dir rename on POSIX, ReplaceFile on
Windows). On rename failure, clean up the temp file so repeated
failed migrations don't pile up .config.toml.* files.

Tests:
  - test_string_with_newline_escaped — \n in value → \n in output

180 codex-runtime tests, all green (+6 from this commit).

Footguns audited but NOT fixed (with rationale):

- Concurrent migrations race. Two Hermes processes hitting
  /codex-runtime codex_app_server within seconds of each other could
  cause one writer to lose entries. Low probability (you'd have to
  enable from two surfaces simultaneously) and low impact (just re-run
  migration). Adding fcntl/msvcrt locking is more code than it's
  worth here. The atomic rename above means each individual write is
  consistent — only the merge step is racy.

- Codex protocol version drift. We pin MIN_CODEX_VERSION=0.125 and
  check at runtime but don't reject too-new versions. Right call —
  the protocol has been stable through 0.125 → 0.130. If OpenAI
  breaks it later we'd see the error in test_codex_app_server_runtime
  on CI before users hit it.

c3094b46e9 refactor: import FILE_MUTATING_TOOL_NAMES from shared module
Drops the duplicate _FILE_MUTATING_TOOLS frozenset in run_agent.py and
imports the canonical FILE_MUTATING_TOOL_NAMES from
agent/tool_result_classification.py (aliased as _FILE_MUTATING_TOOLS to
avoid renaming the existing call sites). Prevents future drift if
another file-mutating tool is added — only one set needs updating.

No behavior change: same frozenset({'write_file', 'patch'}), and the
117 PR-scoped tests still pass.

feat(nous): unified client=hermes-client-v<version> tag on every Portal request (#24779)
* feat(nous): unified client=hermes-client-v<version> tag on every Portal request

Every Hermes request to Nous Portal now carries the same
client=hermes-client-v<__version__> tag (e.g. client=hermes-client-v0.13.0
on this release), sourced live from hermes_cli.__version__. The release
script's regex bump auto-aligns it on every release.

Centralized in agent/portal_tags.py and wired into all four call sites:
- NousProfile.build_extra_body (main agent loop, every chat completion)
- auxiliary_client.NOUS_EXTRA_BODY + _build_call_kwargs (aux client)
- run_agent.py compression-summary fallback path
- tools/web_tools.py web_extract fallback

Replaces the client=aux marker added in #24194 with the unified version
tag. Tests assert against the helper output (invariant) rather than the
literal string, so they don't need updating on every release.

* feat(nous): cover /goal judge and kanban specify aux paths

Two aux-using surfaces bypassed call_llm by invoking
client.chat.completions.create() directly without extra_body, so they
were missing the unified Portal client tag:

- hermes_cli/goals.py — /goal standing-goal judge
- hermes_cli/kanban_specify.py — kanban triage specifier

Both now pass extra_body=get_auxiliary_extra_body() or None so they
inherit the version tag when the aux client points at Nous Portal, and
emit nothing otherwise (no tag leak to OpenRouter/Anthropic auxes).

fix(cache): kill long-lived prefix layout — system prompt is now byte-static within a session (#24778)
The long-lived prefix-cache layout split the system prompt into stable/
context/volatile blocks and re-derived them on every API call. The
volatile tier (timestamp + memory snapshot + USER profile) ticks per
turn, so the system message bytes mutated mid-conversation and broke
upstream prompt caches (OpenRouter, Nous Portal, Anthropic).

Diagnosed via live wire-format diffing: an 8-turn conversation showed
OLD layout flipping system block[1] sha mid-session at the minute
boundary, dropping cached_tokens to 0 on that turn (cumulative
66.6% vs 83.3% for the single-block layout). Hermes invariant:
history (system + all but the last 1-2 messages) must be static.

Fix: drop the long-lived layout entirely. Single layout everywhere —
system_and_3 with one cached system string built once on first turn,
replayed verbatim on every subsequent turn. Loses cross-session 1h
prefix caching for Claude (the feature that motivated the split), but
within-session caching now actually works on every provider.

Removed:
- run_agent.py: _use_long_lived_prefix_cache flag, _long_lived_cache_ttl,
  _supports_long_lived_anthropic_cache method, the long-lived branch in
  run_conversation, mark_tools_for_long_lived_cache call site
- agent/prompt_caching.py: apply_anthropic_cache_control_long_lived,
  mark_tools_for_long_lived_cache, _mark_system_stable_block helper
- hermes_cli/config.py: prompt_caching.long_lived_prefix and
  prompt_caching.long_lived_ttl config keys
- tests/agent/test_prompt_caching_live.py (entire file)
- tests/agent/test_prompt_caching.py: TestMarkToolsForLongLivedCache,
  TestApplyAnthropicCacheControlLongLived
- tests/run_agent/test_anthropic_prompt_cache_policy.py:

8ac351407e fix(agent): clear stale config context_length on model switch
When switching models via /model, AIAgent._config_context_length was
never cleared, so the new model inherited the previous model's context
window instead of auto-detecting the correct one via
get_model_context_length().

Clear _config_context_length to None before the runtime field swap so
the full resolution chain (custom_providers per-model, endpoint probe,
models.dev, etc.) is re-evaluated for the newly selected model.

fix(cache): drop ttl=1h on Portal Qwen — Alibaba upstream is 5m-only (#24702)
PR #24151 routed Portal Qwen (qwen3.6-plus) through the prefix_and_2
long-lived cache layout, attaching {"type":"ephemeral","ttl":"1h"}
markers to the tools[-1] entry and the stable system-prefix block.
That layout works for Portal Claude because Anthropic / OpenRouter on
Anthropic routes honour 1h TTL — but Portal Qwen ultimately proxies to
Alibaba DashScope, which documents a single "ephemeral" TTL of 5
minutes on its Context Cache. The ttl="1h" qualifier is silently
dropped upstream, so the two highest-value breakpoints (tools array +
system prefix) never land. Only the rolling-window 5m markers on the
last 2 messages cache, which matches the observed ~25% read rate.

Fix: keep Portal Qwen on cache_control via _anthropic_prompt_cache_policy
returning (True, False), but drop it from _supports_long_lived_anthropic_cache
so it rides the standard system_and_3 5m layout (system + last 3 messages,
all at 5m). Same 4 breakpoints, all in a TTL the upstream actually honours.

feat(agent): per-turn file-mutation verifier footer (#24498)
Detect when write_file / patch calls fail during a turn and are never
superseded by a successful write to the same path.  When the final
text response is delivered, append an advisory footer listing the
files that did NOT change — so models that over-claim 'patched 5 files'
after 4 silent failures can't hide the lie.

Catches the failure mode reported in Ben Eng's llm-wiki session:
grok-4.1-fast issued batches of parallel patches, half failed with
'Could not find old_string', and the agent summarised the turn
claiming every file was edited.  The user had to manually run
'git status' each turn to catch it.

The verifier is a pure post-hoc check on tool results — no new LLM
calls, no synthetic messages injected into history (prompt cache
preserved), no changes to tool argument dispatch.  Per-turn state is
keyed by path; a later successful write to the same path clears the
failure entry so single-file retry recovery is not flagged.

Wired into both _execute_tool_calls_concurrent and
_execute_tool_calls_sequential, so batched parallel patches and one-at-
a-time edits are both covered.  Footer emission happens after the
agent loop exits, before transform_llm_output / post_llm_call plugin
hooks run, so plugins still see (and can modify) the augmented text.

Config: display.file_mutation_verifier (bool, default true) +
HERMES_FILE_MUTATION_VERIFIER env override.

31 unit tests in tests/run_agent/test_file_mutation_verifier.py cover
target extraction (write_file, patch-replace, patch-v4a single and
multi-file), error-preview extraction (JSON .error field and plain
string), per-turn state transitions (first-error-wins on repeated
failure, success supersedes failure), footer rendering (truncation
at 10 entries, user-actionable hint), and env/config precedence.

Companion docs updated: user-guide/configuration.md +
reference/environment-variables.md.

fix(cache): route Nous Portal Qwen through Portal-Claude cache pathway (#24151)
Qwen models on Nous Portal (e.g. qwen3.6-plus) now get the same envelope-layout
cache_control markers and long-lived (1h cross-session) cache treatment as
Portal Claude. Portal proxies to OpenRouter with identical wire-format and
cache_control semantics, but the prior policy left Portal Qwen falling through
to the alibaba-family branch (which only matches provider=opencode/alibaba),
serving 0% cache hits and re-billing the full prompt every turn.

Scope is narrow: Portal Claude OR Portal Qwen. Other models on Portal keep
their existing behavior.

- _anthropic_prompt_cache_policy: add (is_nous_portal and qwen) -> (True, False)
- _supports_long_lived_anthropic_cache: drop Claude-only gate for Portal so
  Qwen also gets the validated 1h cross-session layout
- tests cover both functions, both bare and vendored qwen slug forms, and
  the rejection of non-Claude non-Qwen Portal traffic

feat: expose HERMES_SESSION_ID to agent tools via ContextVar + env (#23847)
Set HERMES_SESSION_ID using the existing session_context.py ContextVar
system for concurrency safety (multiple gateway sessions in one process
won't cross-talk). Also writes os.environ as fallback for CLI mode.

Touchpoints:
- gateway/session_context.py: Add _SESSION_ID ContextVar + _VAR_MAP entry
- run_agent.py: Set both ContextVar and os.environ at init and on
  context-compression rotation
- tools/environments/local.py: Bridge ContextVars into subprocess env
  in _make_run_env() (ContextVars don't propagate to child processes)
- tests/run_agent/test_session_id_env.py: 3 tests covering env, provided
  ID, and ContextVar paths

execute_code subprocess already passes HERMES_* prefixed vars through
_scrub_child_env (line 82: _SAFE_ENV_PREFIXES includes 'HERMES_').

Primary use case: webhook-triggered agents that need to include a
`--resume <session_id>` takeover command in their output.

feat(prompt-cache): cross-session 1h prefix cache for Claude on Anthropic / OpenRouter / Nous Portal (#23828)
Cuts input cost for first-turn Claude requests by ~85-90% on subsequent
sessions within an hour. Tools array (~13k tokens for default toolset) +
stable system prefix (~5-8k tokens) get a 1h cache_control marker; the
volatile suffix (memory, USER profile, timestamp, session id) sits in a
separate non-cached block at the end so it doesn't poison the cross-session
prefix when it changes.

Provider gate: Claude on native Anthropic (incl. OAuth subscription),
OpenRouter, and Nous Portal (which proxies to OpenRouter). All other
providers keep today's system_and_3 layout unchanged.

Layout (4 cache_control breakpoints, Anthropic max):
  1. tools[-1]              -> 1h (cross-session)
  2. system content[0]      -> 1h (cross-session, stable prefix)
  3. messages[-2]           -> 5m (within-session rolling)
  4. messages[-1]           -> 5m (within-session rolling)

Within-session rolling shrinks from 3 messages to 2 to free the breakpoint
budget. On Claude with realistic tool loadouts the long-lived tier carries
the bulk of cross-session value anyway.

System prompt is now always assembled cache-friendly: stable identity /
guidance / skills / platform hints first, then session-stable context
files (AGENTS.md, .cursorrules), then per-call volatile content. Old
single-string callers see the same logical content (same join order),
just reordered so volatile lives at the end.

Config knobs (defaults shown):
  prompt_caching:
    cache_ttl: "5m"           # rolling-window TTL (unchanged)
    long_lived_prefix: true    # opt-out switch
    long_lived_ttl: "1h"       # cross-session prefix TTL

Live E2E (tests/agent/test_prompt_caching_live.py, gated on
OPENROUTER_API_KEY) on anthropic/claude-haiku-4.5 with default toolset:
  Call 1 (cold):              cache_write=13,415  cache_read=0
  Call 2 (NEW agent + msg):   cache_write=391     cache_read=13,025
  Cross-session reuse:        97.09%

Implementation:
* agent/prompt_caching.py: new apply_anthropic_cache_control_long_lived()
  + mark_tools_for_long_lived_cache(); existing apply_anthropic_cache_control()
  preserved verbatim for the fallback path.
* agent/anthropic_adapter.py: convert_tools_to_anthropic() now forwards
  cache_control onto each Anthropic-format tool dict.
* run_agent.py: _build_system_prompt_parts() returns the 3-tier dict;
  _build_system_prompt() joins them (backward compatible).
  _supports_long_lived_anthropic_cache() policy added next to the existing
  _anthropic_prompt_cache_policy() (which now also recognises Nous Portal
  Claude — pre-existing gap fixed in passing).
  _build_api_kwargs() resolves tools_for_api once and propagates the
  marker through all four build paths (anthropic_messages, bedrock,
  codex_responses, profile/legacy chat completions).
  Long-lived flag plumbed into the runtime snapshot/restore + model-switch
  + fallback-promotion paths.

Tests:
* tests/agent/test_prompt_caching.py: +8 tests (TestMarkToolsForLongLivedCache,
  TestApplyAnthropicCacheControlLongLived).
* tests/run_agent/test_anthropic_prompt_cache_policy.py: +9 tests
  (TestSupportsLongLivedAnthropicCache matrix across 8 endpoint classes
  + a fallback-target case).
* tests/agent/test_prompt_caching_live.py: new live E2E (skipif when
  OPENROUTER_API_KEY is unset; runs outside the hermetic suite).
* Targeted suites: 327/327 pass (caching/adapter/policy/builder).
* tests/agent/ + tests/run_agent/: 3992 pass, 17 skip, 1 pre-existing
  flake (test_async_httpx_del_neuter::test_same_key_replaces_stale_loop_entry,
  verified failing on pristine origin/main).

fix(agent): catch ChatGPT-account Codex data-URL rejection so images are stripped instead of cascading to compression (#23602)
When the user's main provider is openai-codex on the ChatGPT-account
backend (https://chatgpt.com/backend-api/codex), sending a native image
attachment encodes it as data:image/...base64,... in the input_image
field. The OpenAI Responses API on the public endpoint accepts that, but
the ChatGPT-account variant rejects it with HTTP 400:

  Invalid 'input[N].content[K].image_url'. Expected a valid URL, but got
  a value with an invalid format.

Hermes' image-rejection phrase list didn't include this wording, so the
error escaped the strip-and-retry branch and fell through to the generic
recovery path: model fallback → context-too-large → compression cascade
→ auxiliary OpenRouter 402 spam (issue #23570).

Add a NARROW phrase keyed on the field-path apostrophe used by the Codex
Responses error format: "image_url'. expected". This matches the actual
error format without false-tripping on generic 'Expected a valid URL'
errors from unrelated tools (webhooks, redirect_uri, etc.). Once matched,
the existing branch strips images from history, sets _vision_supported=
False for the session, and retries text-only.

store image PATHS instead of inlined base64 is a separate follow-up)

2b3bf17dfa fix(kanban): call kanban_block on iteration-budget exhaustion to prevent protocol violation
When a kanban worker subprocess hits the iteration budget, the agent
loop strips tools and asks the model for a summary.  The model cannot
call kanban_block itself at that point, so the process exits rc=0
without calling kanban_complete or kanban_block — a protocol violation
that the dispatcher detects as a fatal error, giving up after 1 failure
and stranding downstream tasks.

Fix: after _handle_max_iterations() returns, check HERMES_KANBAN_TASK
and call kanban_block with a reason describing the exhaustion.  The
dispatcher then sees a clean block transition instead of a protocol
violation, and the task can be retried or escalated by a human.

exhaustion without calling kanban_complete or kanban_block #23216

3af3c4eb8c fix(misc): three small defensive fixes from PR #1974
Salvages the three substantive low-severity fixes from Gutslabs' #1974
"misc bug fixes" bundle.  The other 8 claims in that PR were either
already fixed on main with superior implementations (state lock,
firecrawl lazy import, fcntl/msvcrt guard, path normalization, schema
migrations) or did not survive review.

- run_agent: `_materialize_data_url_for_vision` uses
  `NamedTemporaryFile(delete=False)`; if `base64.b64decode` raises on a
  corrupt data URL the temp file would persist forever.  Wrap the
  write in try/except and `os.unlink` the temp on failure.

- gateway/session: `append_to_transcript` JSONL write had no error
  handling, so disk-full / read-only-fs / permission errors crashed the
  message handler.  The SQLite write above is the primary store, so
  swallow OSError on the JSONL fallback with a debug log.

- gateway/status: `_read_pid_record` reads `pid_path.read_text()` after
  an `exists()` check; if the PID file is deleted between the two
  calls (concurrent gateway restart) we hit an unhandled OSError.
  Catch it and return None.

Adds a regression test for the tempfile cleanup; the other two paths
are defensive try/excepts on infrequent OSError that don't warrant
dedicated tests.

fix(goals): forward standing /goal state on auto-compression session rotation (#23530)
When run_agent's _compress_context fires mid-turn it ends the parent
session in SessionDB and creates a new continuation session with a
fresh session_id. The /goal state is keyed on session_id in
state_meta ("goal:<sid>"), so without forwarding the goal silently
disappears: _get_goal_manager() rebinds for the new session_id,
load_goal() returns None, mgr.is_active() is False, and the
continuation loop dies with no user-visible signal.

Fix: in the same SessionDB transaction block that creates the
continuation session, copy state_meta[goal:<old>] →
state_meta[goal:<new>] when present. No-op when the user has no
active goal. Logged at INFO so a stuck loop is debuggable.

Tests cover the round-trip via SessionDB and the no-op path.

Affects all three run-conversation surfaces (CLI, gateway, TUI
gateway) because _compress_context is the single rotation site.

fix(review): tell background reviewer not to capture transient env failures as skills (#23004)
Closes #6051.

Reported failure mode: agent migrated to WSL2, browser launch failed
because Playwright wasn't installed yet. Background reviewer captured
the failure as a durable skill (`browser-tool-launch-issue`) and the
agent kept refusing the browser tool for weeks after Playwright was
installed and verified working. Negative claims also propagated into
unrelated skills ("browser tools do not work", "cannot use Y from
execute_code").

Root cause: `_SKILL_REVIEW_PROMPT` and `_COMBINED_REVIEW_PROMPT` both
lean hard on "be active, save things, a pass that does nothing is a
missed learning opportunity." Neither distinguished durable knowledge
from transient environment state. The reviewer was doing what it was
told.

Fix at the write site — both prompts now carry a "Do NOT capture"
section calling out:
  • Environment-dependent failures (missing binaries, fresh-install
    errors, post-migration path mismatches, 'command not found',
    unconfigured credentials, uninstalled packages)
  • Negative claims about tools or features ("X does not work")
    that harden into self-cited refusals
  • Session-specific transient errors that resolved before the
    conversation ended
  • One-off task narratives ("summarize today's market", "analyze
    this PR") — also addresses the #12812 / #4538 family

Plus a positive-reframing line: when a tool fails because of setup
state, capture the FIX (install command, config step, env var)
under an existing setup/troubleshooting skill — never "this tool
doesn't work" as a standalone constraint.

Targeted tests: 24/24 passing in tests/run_agent/test_review_prompt_class_first.py
(2 new + all existing review-prompt assertions). Substring-based
checks so future prompt edits don't false-fail.

feat(stream-retry): add upstream + timing diagnostics to drop log (#23005)
The previous PR (#22993) gave us a structured WARNING per stream drop
but the only diagnostic was 'error_type=APIError error=Network
connection lost.' — same nothing the user started with. To actually
diagnose why subagents drop streams disproportionately we need to know
WHERE the drop happened.

Adds three breadcrumbs to the agent.log WARNING:

1. Inner exception chain. openai SDK wraps httpx errors as
   APIConnectionError / APIError so the catch site only sees the
   wrapper. _flatten_exception_chain walks __cause__/__context__ up to
   4 levels deep and renders 'Outer(msg) <- Inner(msg)' so we can
   tell ConnectError vs RemoteProtocolError vs ReadError vs
   ProxyError without enabling verbose mode.

2. Upstream HTTP headers. Snapshots cf-ray, x-openrouter-provider,
   x-openrouter-model, x-openrouter-id, x-request-id, server, via,
   etc. from stream.response immediately after open (so they survive
   even when the stream dies before the first chunk). These answer
   'is one CF edge / one downstream provider responsible, or random?'

3. Per-attempt counters. bytes streamed, chunk count, elapsed time on
   the dying attempt, and time-to-first-byte. Distinguishes 'couldn't
   connect at all' (0s, 0 bytes) from 'died after 30s mid-stream'
   (very different root causes — first is auth/routing, second is
   upstream idle-kill or proxy timeout).

Plumbing:

- _stream_diag_init / _stream_diag_capture_response live on AIAgent
  and produce a per-attempt dict held on request_client_holder['diag']
  for closure access from the retry block.
- _call_chat_completions and _call_anthropic both initialize the diag
  and increment counters per chunk/event (best-effort, never raises in
  the streaming hot path).
- _log_stream_retry / _emit_stream_drop accept an optional diag and
  render the new fields. Final-exhaustion log goes through the same
  helper so it gets the same diagnostic dump.
- UI status line gains a brief 'after Xs' suffix when timing is
  available — distinguishes 'connect failed' from 'died mid-stream'
  at a glance without grepping logs.

Sample WARNING after this change:

  Stream drop mid tool-call on attempt 2/3 — retrying.

fix(stream-retry): collapse two-line drop status, name provider, and let agent.log capture diagnostics (#22993)
Subagent stream drops were spamming the parent terminal with two lines
per blip ('Connection dropped...' + 'Reconnected...') while leaving zero
breadcrumb in agent.log to debug them.

Two underlying bugs, fixed together:

1. quiet_mode raised the run_agent/tools/etc. loggers to ERROR, which
   filters records before root-logger file handlers see them. The comment
   claimed 'File handlers still capture everything' — that was wrong.
   Removed in both run_agent.py and cli.py; console quietness already
   comes from hermes_logging not installing a console StreamHandler in
   non-verbose mode.

2. The stream-retry blocks emitted two _emit_status calls per drop
   ('⚠️ Connection dropped... Reconnecting...' + '🔄 Reconnected —
   resuming…') with no provider name, so multi-provider sessions had to
   dig through agent.log to attribute a drop. Replaced both call sites
   with a single _emit_stream_drop helper that emits ONE line naming the
   provider and error class, and always writes a structured WARNING to
   agent.log with subagent_id, depth, provider, base_url, error_type.

Net UX change: 6 lines per triple-subagent drop → 3 lines, each
naming the provider. agent.log now has a structured breadcrumb per
retry that didn't exist before.

Tests: 6 new tests in tests/run_agent/test_stream_drop_logging.py
covering the logger-level guard, structured WARNING content, single
status line per drop (no Reconnected follow-up), and provider naming.

feat(vision): vision_analyze returns pixels to vision-capable models, not aux text (#22955)
When the active main model has native vision and the provider supports
multimodal tool results (Anthropic, OpenAI Chat, Codex Responses, Gemini
3, OpenRouter, Nous), vision_analyze loads the image bytes and returns
them to the model as a multimodal tool-result envelope. The model then
sees the pixels directly on its next turn instead of receiving a lossy
text description from an auxiliary LLM.

Falls back to the legacy aux-LLM text path for non-vision models and
unverified providers.

Mirrors the architecture used in OpenCode, Claude Code, Codex CLI, and
Cline. All four converge on the same pattern: tool results carry image
content blocks for vision-capable provider/model combinations.

Changes
- tools/vision_tools.py: _vision_analyze_native fast path + provider
  capability table (_supports_media_in_tool_results). Schema description
  updated to reflect new behaviour.
- agent/codex_responses_adapter.py: function_call_output.output now
  accepts the array form for multimodal tool results (was string-only).
  Preflight validates input_text/input_image parts.
- agent/auxiliary_client.py: _RUNTIME_MAIN_PROVIDER/_MODEL globals so
  tools see the live CLI/gateway override, not the stale config.yaml
  default. set_runtime_main()/clear_runtime_main() helpers.
- run_agent.py: AIAgent.run_conversation calls set_runtime_main at turn
  start so vision_analyze's fast-path check sees the actual runtime.
- tests/conftest.py: clear runtime-main override between tests.

Tests
- tests/tools/test_vision_native_fast_path.py: provider capability
  table, envelope shape, fast-path gating (vision-capable model uses
  fast path; non-vision model falls through to aux).
- tests/run_agent/test_codex_multimodal_tool_result.py: list tool
  content becomes function_call_output.output array; preflight
  preserves arrays and drops unknown part types.

Live verified
- Opus 4.6 + Sonnet 4.6 on OpenRouter: model calls vision_analyze on a
  typed filepath, gets pixels back, reads exact text from images that
  no aux description could capture (font color irony, multi-line
  fruit-count list, etc.).

PR replaces the closed prior efforts (#16506 shipped the inbound user-
attached path; this PR closes the gap for tool-discovered images).

6ddc48b058 fix(fallback): resolve api_key_env in fallback chain entries (carve-out of #22665)
Fallback chain entries with 'api_key_env: ENV_VAR_NAME' weren't being
resolved by either the init-time fallback path (line ~1660) or the
runtime _try_activate_fallback path (line ~8045). Only literal
'api_key' was honored; the snake_case 'api_key_env' alias documented
elsewhere in the config was silently dropped, so a 'provider: custom'
fallback with base_url + api_key_env worked as primary but failed as
fallback with 'no endpoint credentials found' / 401.

Adds 'or fb.get("api_key_env")' to the existing 'key_env' lookup in
both call sites, with empty-string-to-None coercion so unset env vars
don't poison the resolver.

Salvage of #22665's fallback portion. The original PR also bundled
gateway-degrade-on-no-adapters changes (those land via the carve-out
in #22853 which is the same code) and run_agent.py memory-nudge
counter hydration (issue #22357 territory, not mentioned in the
title). Drops both bundled pieces; keeps just the api_key_env fix.

Closes #5392.

feat(openrouter): wire Pareto Code router with min_coding_score knob (#22838)
Pick openrouter/pareto-code as your model and OpenRouter auto-routes each
request to the cheapest model meeting your coding-quality bar (ranked by
Artificial Analysis). The new openrouter.min_coding_score config key (0.0-1.0,
default 0.65) tunes the floor.

- hermes_cli/models.py: add openrouter/pareto-code to OPENROUTER_MODELS so
  it shows up in the picker with a description
- hermes_cli/config.py: add openrouter.min_coding_score (default 0.65 — lands
  on a mid-tier coder on the current Pareto frontier)
- plugins/model-providers/openrouter: emit extra_body.plugins =
  [{id: pareto-router, min_coding_score: X}] when model is openrouter/pareto-code
  AND the score is a valid float in [0.0, 1.0]
- agent/transports/chat_completions.py: same emission on the legacy flag
  path (when no provider profile is loaded)
- run_agent.py: openrouter_min_coding_score kwarg + storage; plumbed into
  both build_kwargs() invocations and the context-summary extra_body path
- cli.py: read openrouter.min_coding_score once at init, validate float in
  [0,1], pass to AIAgent constructions (CLI + background-task paths)
- cron/scheduler.py, batch_runner.py, tools/delegate_tool.py,
  tui_gateway/server.py: propagate the kwarg (mirrors providers_order
  plumbing — subagents inherit, cron/batch read from config)
- tests: profile-level + transport-level coverage of the model gating,
  unset/empty/out-of-range handling, and the legacy flag path
- docs: new 'OpenRouter Pareto Code Router' section in providers.md

Verified end-to-end against api.openrouter.ai: at score=0.65 we land on a
mid-tier coder, at omission we get the strongest. Score is silently dropped
on any model other than openrouter/pareto-code, so it's safe to leave set.

68854cdcdb fix(agent): extract thinking from content-list blocks for DeepSeek V4 Pro
DeepSeek V4 Pro returns thinking content as typed blocks inside the
content array rather than as a top-level reasoning_content field:

  [{"type": "thinking", "thinking": "..."}, {"type": "output", ...}]

_extract_reasoning only handled content as a plain string, so the
thinking text was silently dropped.  On the next turn the session was
replayed without the thinking block, causing:

  HTTP 400: The content[].thinking in the thinking mode must be
  passed back to the API.

Fix: when content is a list and no structured reasoning field was
found, scan for items with type=='thinking' and accumulate their
'thinking' (or 'text') value into reasoning_parts.  Structured fields
(reasoning, reasoning_content, reasoning_details) still take priority
so existing provider behaviour is unchanged.

fix(fallback): skip chain entries matching current provider/model/base_url (#22780)
_try_activate_fallback() walked the chain by index without comparing
the candidate entry against the currently-failing backend. So a
misconfigured chain that listed the same provider+model as the primary,
or two custom_providers entries pointing at the same shim URL, would
loop the same failure 3x for the same backend.

After the fix, advance() skips:
  - entries where (provider, model) match the current agent's
  - entries with a base_url + model matching the current backend
    (catches two custom_providers names pointing at the same shim)

Recursing through self._try_activate_fallback() continues to the next
chain entry; if everything matches, returns False and the caller
moves on without retrying the same broken path.

3 regression tests covering same-provider-same-model skip, same-base_url-
same-model skip, and the all-self-matching-returns-False exhaustion path.

Closes #22548 (the Hermes-side portion). The 120s timeout itself in
the downstream claude-cli shim is a deployment concern documented in
that issue's wherewolf87 comment.

fix(agent): hydrate memory-nudge counters from conversation_history (#22774)
Gateway creates a fresh AIAgent per inbound message in several common
scenarios: cache miss, idle eviction (1h TTL), config-signature
mismatch, process restart. A freshly-built AIAgent has
_turns_since_memory=0 and _user_turn_count=0, so the
memory.nudge_interval trigger ('_turns_since_memory >=
_memory_nudge_interval') can never be reached when these reconstructions
happen on roughly the cadence of the interval. A user can chat for hours
on Telegram without ever seeing a self-improvement review fire.

Reconstruct the counters from conversation_history at the top of
run_conversation(), right after the existing _hydrate_todo_store call.
Idempotent guard ('if self._user_turn_count == 0') means a cached agent
that already accumulated counters keeps them; only freshly-built agents
hydrate. Modulo arithmetic preserves the original 1-in-N cadence rather
than firing a review immediately on resume.

7 regression tests pinning the contract (mid-cycle history, modulo wrap,
idempotency, zero-interval skip, role==user filtering, production-code
anchor).

Closes #22357.

fix(agent): notify context engine on commit_memory_session (#22764)
When session_id rotates (e.g. /new), commit_memory_session was firing
MemoryManager.on_session_end but skipping ContextEngine.on_session_end.
Engines that accumulate per-session state (LCM-style DAGs, summary
stores) leaked that state from the rotated-out session into whatever
continued under the same compressor instance.

Mirror the call shutdown_memory_provider already makes — same
lifecycle moment, same hook contract ("real session boundaries (CLI
exit, /reset, gateway expiry)"). /new is a real boundary for the old
session_id; providers keep their state but the rotated-out session_id
is done.

fix(sqlite): fall back to journal_mode=DELETE on NFS/SMB/FUSE (#22043)
SQLite's WAL mode requires shared-memory (mmap) coordination and fcntl
byte-range locks that don't reliably work on network filesystems. Upstream
documents this explicitly:
  https://www.sqlite.org/wal.html#sometimes_queries_return_sqlite_busy_in_wal_mode

On NFS / SMB / some FUSE mounts / WSL1, 'PRAGMA journal_mode=WAL' raises
'sqlite3.OperationalError: locking protocol' (SQLITE_PROTOCOL). Before
this change, every feature backed by state.db or kanban.db broke silently:
  - /resume, /title, /history, /branch returned 'Session database not
    available.' with no cause
  - gateway logged the init failure at DEBUG (invisible in errors.log)
  - kanban dispatcher crashed every 60s, driving the known migration race
    (duplicate column name: consecutive_failures, #21708 / #21374)

Changes:
  - hermes_state.apply_wal_with_fallback(): shared helper that tries WAL
    and falls back to DELETE on SQLITE_PROTOCOL-style errors with one
    WARNING explaining why
  - hermes_state.get_last_init_error() + format_session_db_unavailable():
    capture the init failure cause and surface it in user-facing strings
    (with an NFS/SMB pointer for 'locking protocol')
  - hermes_cli/kanban_db.connect(): use the shared helper
  - gateway/run.py: bump SessionDB init failure log DEBUG -> WARNING
    (matches cli.py's existing correct behavior)
  - cli.py (4 sites) + gateway/run.py (5 sites): replace bare
    'Session database not available.' with format_session_db_unavailable()

Tests: 12 new tests in tests/test_hermes_state_wal_fallback.py + 1 new
test in tests/hermes_cli/test_kanban_db.py. Existing suites (state,
kanban, gateway, cli) remain green for all tests unrelated to pre-existing
failures on main.

Evidence: real-world user on NFSv3 mount (172.26.224.200:d2dfac12/home,
local_lock=none) reporting 'Session database not available.' on /resume;
'locking protocol' appears in 4 distinct log entries across backup,
kanban, TUI, and CLI paths in the same session.

fix(entry-points): guard hermes_bootstrap import so partial updates don't brick hermes (#22091)
teknium1 hit ModuleNotFoundError: No module named 'hermes_bootstrap' after
a code update, on both his Windows machine AND his Linux workstation.  The
failure mode is real and affects every user who updates hermes by any path
OTHER than a fully-successful ``hermes update``.

## What happens

hermes_bootstrap.py is a top-level module registered via pyproject.toml's
``py-modules`` list (added by Brooklyn's Windows UTF-8 stdio work).  It
must be registered in the venv's editable-install .pth file before Python
can find it as a bare ``import hermes_bootstrap``.

``hermes update`` handles this correctly: (1) git reset --hard, (2) clear
__pycache__, (3) uv pip install -e . (re-registers the package including
the new py-modules list), (4) restart.

BUT if any step AFTER (1) fails — network blip during pip install, PEP 668
on a system Python, venv locked, uv not in PATH, a crash mid-update — the
user is left with new code that references hermes_bootstrap and a venv
that doesn't know about it.  Every hermes invocation after that crashes
with ModuleNotFoundError, including ``hermes update`` itself.  No recovery
path without manual `uv pip install -e .`.

Also affects users who ``git pull`` the repo directly without running
hermes update — relatively common for developers.

## Fix

Wrap ``import hermes_bootstrap`` in a try/except ModuleNotFoundError
across all 6 entry points (hermes_cli/main, run_agent, gateway/run,
acp_adapter/entry, cli, batch_runner).  On Windows, missing bootstrap
means the UTF-8 stdio setup doesn't run — degraded behavior (Unicode
chars may fail to print) but NOT a crash.  POSIX is unaffected either way
since the bootstrap is a no-op there.

Once hermes is running again, the user can ``hermes update`` to fully
recover.

## Test update

tests/test_hermes_bootstrap.py::test_entry_point_imports_bootstrap
scans for the first top-level import in each entry point and asserts it
is hermes_bootstrap.  Extended the check to accept a Try block whose body
is a lone Import of hermes_bootstrap — that's the recovery-friendly form
we just introduced.

Verified behavior by ``mv hermes_bootstrap.py hermes_bootstrap.py.bak``
and confirming ``python -c "import hermes_cli.main"`` succeeds.  82/82
tests pass (hermes_bootstrap + windows-native + windows-compat).

cbce5e93fc codebase: add encoding='utf-8' to all bare open() calls (PLW1514)
Closes the last Python-on-Windows UTF-8 exposure by making every
text-mode open() call explicit about its encoding.

Before: on Windows, bare open(path, 'r') defaults to the system
locale encoding (cp1252 on US-locale installs).  That means reading
any config/yaml/markdown/json file with non-ASCII content either
crashes with UnicodeDecodeError or silently mis-decodes bytes.

After: all 89 affected call sites in production code now pass
encoding='utf-8' explicitly.  Works identically on every platform
and every locale, no surprise behavior.

Mechanical sweep via:
  ruff check --preview --extend-select PLW1514 --unsafe-fixes --fix     --exclude 'tests,venv,.venv,node_modules,website,optional-skills,               skills,tinker-atropos,plugins' .

All 89 fixes have the same shape: open(x) or open(x, mode) became
open(x, encoding='utf-8') or open(x, mode, encoding='utf-8').  Nothing
else changed.  Every modified file still parses and the Windows/sandbox
test suite is still green (85 passed, 14 skipped, 0 failed across
tests/tools/test_code_execution_windows_env.py +
tests/tools/test_code_execution_modes.py + tests/tools/test_env_passthrough.py +
tests/test_hermes_bootstrap.py).

Scope notes:
  - tests/ excluded: test fixtures can use locale encoding intentionally
    (exercising edge cases).  If we want to tighten tests later that's
    a separate PR.
  - plugins/ excluded: plugin-specific conventions may differ; plugin
    authors own their code.
  - optional-skills/ and skills/ excluded: skill scripts are user-authored
    and we don't want to mass-edit them.
  - website/ and tinker-atropos/ excluded: vendored / generated content.

46 files touched, 89 +/- lines (symmetric replacement).  No behavior
change on POSIX or on Windows when the file is ASCII; bug fix on
Windows when the file contains non-ASCII.

d94fb47717 hermes_bootstrap: Windows-only UTF-8 stdio shim for all entry points
Codebase-wide fix for Python-on-Windows UTF-8 footguns, complementing
the earlier execute_code sandbox fixes (which remain load-bearing for
when the sandbox explicitly scrubs child env).

Problem: Python on Windows has two long-standing text-encoding pitfalls:

  1. sys.stdout/stderr are bound to the console code page (cp1252 on
     US-locale installs) — print('café') crashes with UnicodeEncodeError.
  2. Subprocess children don't know to use UTF-8 unless PYTHONUTF8 and/or
     PYTHONIOENCODING are set in their env — so any Python we spawn
     (linters, sandbox children, delegation workers) hits the same bug.

Solution: A tiny bootstrap module (hermes_bootstrap.py) imported as the
first statement of every Hermes entry point:

  - hermes_cli/main.py   (hermes / hermes-agent console_script)
  - run_agent.py         (hermes-agent direct)
  - acp_adapter/entry.py (hermes-acp)
  - gateway/run.py       (messaging gateway)
  - batch_runner.py      (parallel batch mode)
  - cli.py               (legacy direct-launch CLI)

On Windows, the bootstrap:
  - os.environ.setdefault('PYTHONUTF8', '1')       (PEP 540 UTF-8 mode)
  - os.environ.setdefault('PYTHONIOENCODING', 'utf-8')
  - sys.stdout/stderr/stdin.reconfigure(encoding='utf-8', errors='replace')

Children inherit the env vars → they run in UTF-8 mode.
Current process's stdio is reconfigured → print('café') works now.

On POSIX (Linux/macOS), the bootstrap is a complete no-op.  We don't
touch LANG, LC_*, or anything else — users who have intentionally
configured a non-UTF-8 locale aren't affected.  POSIX systems are
already UTF-8 by default in 99% of modern setups, so there's nothing
to fix.

setdefault() (not overwrite) means users who explicitly set PYTHONUTF8=0
or PYTHONIOENCODING=cp1252 in their environment are respected.

What this does NOT fix: bare open(path, 'w') calls in the *parent*
process still default to locale encoding because PYTHONUTF8 is only
read at interpreter init.  A ruff PLW1514 sweep (separate follow-up)
will add explicit encoding='utf-8' at those ~219 call sites for
belt-and-suspenders.

Tests (17): 16 passed, 1 skipped on Windows.
  - Windows: env vars set, stdio reconfigured, child inherits UTF-8 mode
  - POSIX: complete no-op (verified on fake POSIX + skipped on real
    POSIX since we don't have a Linux box in this session)
  - Idempotence: multiple calls safe
  - Graceful degradation: non-reconfigurable streams don't crash
  - User opt-out: explicit PYTHONUTF8=0 is respected
  - Load order: every entry point's FIRST top-level import is
    hermes_bootstrap, enforced by an AST-level parametrized test

pyproject.toml: added hermes_bootstrap to py-modules so it ships with
pip installs.

d0aad4b021 fix(computer-use): harden image-rejection fallback + AUTHOR_MAP
Follow-up to #15328's vision-unsupported retry branch in run_agent.py.

_strip_images_from_messages() previously deleted any message whose content
was entirely images. That's fine for synthetic user messages injected for
attachment delivery, but it breaks providers for tool-role messages — the
paired tool_call_id on the preceding assistant message ends up unmatched,
which OpenAI-compatible APIs reject with HTTP 400.

Fix: tool-role messages whose content becomes empty are replaced with a
plaintext placeholder that preserves the tool_call_id linkage. Only
non-tool messages are dropped. Added 10 tests covering the role-alternation
invariants + image-type coverage.

Image-rejection detector: expanded phrase list (image content not
supported / multimodal input / vision input / model does not support
image) and gated on 4xx status so transient 5xx errors never get
misinterpreted as 'server said no to images'. Detection is documented as
best-effort English phrase matching.

AUTHOR_MAP: mapped 3820588+ddupont808@users.noreply.github.com to
ddupont808 so release notes attribute the salvage correctly.

2937f9bef6 fix(computer-use): unwrap _multimodal tool results to content list for non-Anthropic providers
Tool handlers (e.g. computer_use capture) return a _multimodal envelope
dict when a screenshot is attached. The tool-message builder was passing
this raw dict as the `content` field of role:tool messages, which is an
illegal format — OpenAI-compatible APIs expect a string or a content-parts
list, not a plain Python dict, and would reject it with a 400/422 error.

Fix: unwrap _multimodal results to their `content` list
([{type:text,...},{type:image_url,...}]) in both the parallel and
sequential tool-call paths. The Anthropic adapter already handles content
lists natively; vision-capable OpenAI-compatible servers (mlx-vlm,
GPT-4o, etc.) accept image_url parts in tool messages directly.

Also add a _vision_supported adaptive fallback: on first image-rejection
error ("Only 'text' content type is supported." etc.) the agent strips all
image parts from the message history and retries with text only, so
text-only endpoints degrade gracefully without crashing the session.

e31f3b3c56 feat(computer-use): background focus-safe backend — set_value, structured windows, MIME detection
Extends the cua-driver computer-use backend to drive backgrounded macOS
windows without stealing keyboard or mouse focus from the foreground app.
All changes target the cua-driver MCP backend and the shared dispatcher.

## cua_backend.py

**Window-aware capture**: capture() now calls list_windows + get_window_state
instead of the removed capture tool. Prefers structuredContent.windows
(MCP 2024-11-05+ cua-driver) for zero-parse window enumeration; falls back
to regex-parsed text for older builds. Stores the selected (pid, window_id)
as sticky context so subsequent action calls do not need a redundant round-trip.

**Action routing**: click/scroll/type_text/key all carry the sticky pid
(and window_id for element-indexed clicks). type_text routes through
type_text_chars (individual key events) rather than AX attribute write --
WebKit AXTextFields reject attribute writes from backgrounded processes.

**Key parsing**: _parse_key_combo splits cmd+s-style strings into
(key, [modifiers]) and routes to hotkey (modifier present) or
press_key (bare key) -- cua-driver actual tool names.

**set_value method**: new set_value(value, element) calls the cua-driver
set_value MCP tool. For AXPopUpButton / HTML select in a backgrounded Safari,
AXPress opens the native macOS popup which closes immediately when the app is
non-frontmost; set_value AX-presses the matching child option directly
(no menu required, no focus steal).

**focus_app**: reimplemented as a pure window-selector (enumerates
list_windows, sets sticky pid/window_id) without ever raising the window
or stealing focus.

**list_apps**: fixed tool name from listApps to list_apps; handles plain-text
response via regex when structured data is absent.

**Structured-content extraction**: _extract_tool_result now surfaces
structuredContent from MCP results, enabling the list_windows window array
without text parsing.

**Helpers**: _parse_windows_from_text, _parse_elements_from_tree,
_split_tree_text, _parse_key_combo extracted as module-level functions.

## schema.py

Added set_value to the action enum with a description explaining when to
prefer it over click (select/popup elements, sliders, no focus steal).
Added value field for set_value payloads.

## tool.py

Routed set_value action through _dispatch to backend.set_value.
Added set_value to _DESTRUCTIVE_ACTIONS (approval-gated).
Fixed MIME-type detection in _capture_response: cua-driver may return
JPEG; detect from base64 magic bytes (/9j/ -> image/jpeg, else image/png)
rather than hardcoding image/png.

## agent/display.py + run_agent.py

Guard _detect_tool_failure and result-preview logic against non-string
function_result values: multimodal tool results (dicts with _multimodal=True)
are not string-sliceable; treat them as successes and fall back to str()
for length/preview.

abandoned #4562 with a generic OpenAI function-calling schema plus SOM
(set-of-mark) captures so Claude, GPT, Gemini, and open models can all
drive the desktop via numbered element indices.

- `tools/computer_use/` package — swappable ComputerUseBackend ABC +
  CuaDriverBackend (stdio MCP client to trycua/cua's cua-driver binary).
- Universal `computer_use` tool with one schema for all providers.
  Actions: capture (som/vision/ax), click, double_click, right_click,
  middle_click, drag, scroll, type, key, wait, list_apps, focus_app.
- Multimodal tool-result envelope (`_multimodal=True`, OpenAI-style
  `content: [text, image_url]` parts) that flows through
  handle_function_call into the tool message. Anthropic adapter converts
  into native `tool_result` image blocks; OpenAI-compatible providers
  get the parts list directly.
- Image eviction in convert_messages_to_anthropic: only the 3 most
  recent screenshots carry real image data; older ones become text
  placeholders to cap per-turn token cost.
- Context compressor image pruning: old multimodal tool results have
  their image parts stripped instead of being skipped.
- Image-aware token estimation: each image counts as a flat 1500 tokens
  instead of its base64 char length (~1MB would have registered as
  ~250K tokens before).
- COMPUTER_USE_GUIDANCE system-prompt block — injected when the toolset
  is active.
- Session DB persistence strips base64 from multimodal tool messages.
- Trajectory saver normalises multimodal messages to text-only.
- `hermes tools` post-setup installs cua-driver via the upstream script
  and prints permission-grant instructions.
- CLI approval callback wired so destructive computer_use actions go
  through the same prompt_toolkit approval dialog as terminal commands.
- Hard safety guards at the tool level: blocked type patterns
  (curl|bash, sudo rm -rf, fork bomb), blocked key combos (empty trash,
  force delete, lock screen, log out).
- Skill `apple/macos-computer-use/SKILL.md` — universal (model-agnostic)
  workflow guide.
- Docs: `user-guide/features/computer-use.md` plus reference catalog
  entries.

44 new tests in tests/tools/test_computer_use.py covering schema
shape (universal, not Anthropic-native), dispatch routing, safety
guards, multimodal envelope, Anthropic adapter conversion, screenshot
eviction, context compressor pruning, image-aware token estimation,
run_agent helpers, and universality guarantees.

469/469 pass across tests/tools/test_computer_use.py + the affected
agent/ test suites.

- `model_tools.py` provider-gating: the tool is available to every
  provider. Providers without multi-part tool message support will see
  text-only tool results (graceful degradation via `text_summary`).
- Anthropic server-side `clear_tool_uses_20250919` — deferred;
  client-side eviction + compressor pruning cover the same cost ceiling
  without a beta header.

- macOS only. cua-driver uses private SkyLight SPIs
  (SLEventPostToPid, SLPSPostEventRecordTo,
  _AXObserverAddNotificationAndCheckRemote) that can break on any macOS
  update. Pin with HERMES_CUA_DRIVER_VERSION.
- Requires Accessibility + Screen Recording permissions — the post-setup
  prints the Settings path.

Supersedes PR #4562 (pyautogui/Quartz foreground backend, Anthropic-
native schema). Credit @0xbyt4 for the original #3816 groundwork whose
context/eviction/token design is preserved here in generic form.

fix(model-switch): prevent stale Ollama credentials after provider switch (#21703)
When switching from a custom local provider (e.g. ollama-launch) to a
cloud provider, two bugs caused the CLI to misbehave:

1. _explicit_api_key/_explicit_base_url were only updated when the switch
   result had non-empty values (guarded by `if result.api_key:` etc.).
   If the previous provider set these to Ollama values ("ollama",
   "http://127.0.0.1:11434/v1"), those stale values leaked into the next
   turn's _ensure_runtime_credentials() call and were forwarded to the
   new provider's API endpoint, causing authentication/routing failures.

   Fix: unconditionally write result.api_key/base_url into the explicit
   fields after every successful switch. An empty string is the correct
   sentinel — it tells _ensure_runtime_credentials to re-resolve from the
   auth store / config rather than forwarding a stale override.

2. In AIAgent.switch_model(), `self.base_url = base_url or self.base_url`
   kept the old Ollama localhost URL whenever the incoming base_url was an
   empty string. For providers that use a native SDK (not an OpenAI-compat
   endpoint), the caller passes base_url="" and expects the agent to clear
   the field — not silently inherit Ollama's address.

   Fix: only update self.base_url when base_url is truthy.

3. _handle_model_picker_selection() was called from the prompt_toolkit
   Enter key binding without any exception guard. Any unexpected error
   in the model-selection code path propagated through prompt_toolkit's
   key-binding dispatcher and caused the entire TUI to exit — which the
   user sees as "the terminal exits when I switch providers".

   Fix: wrap the call in try/except and close the picker on failure.

fix(run_agent): break permanent empty-response loop from orphan tool-tail (#21385)
When empty-response terminal scaffolding fires on a tool-result turn,
_drop_trailing_empty_response_scaffolding left the live history ending at
a bare 'tool' message. The next user input then landed as [...tool, user],
a protocol-invalid sequence that OpenRouter/Opus and other providers
silently fail on (returns empty content). That retriggered the empty-retry
recovery every turn, and recovery flags never hit SQLite (no column for
them), so history kept looking broken on every reload.

Two fixes:

1. Scaffolding strip rewinds the orphan assistant(tool_calls)+tool pair
   after popping sentinels. Only fires when scaffolding flags were
   actually present, so mid-iteration tool loops are untouched.

2. _repair_message_sequence runs right before every API call as a
   defensive belt: drops stray tool messages with unknown tool_call_ids,
   merges consecutive user messages so no user input is lost. Does NOT
   rewind assistant(tool_calls)+tool+user — that pattern is valid when
   the user redirected before the model got its continuation turn.

Repro: session 20260507_044111_fa7e65. Opus-4.7/OpenRouter returned
content-less response after a 42KB execute_code output, nudge+retry
chain exhausted (no fallback configured), terminal sentinel appended,
scaffolding stripped leaving bare tool tail, user typed 'wtf happened..'
and landed as tool→user violation. Every subsequent turn collapsed in
<50ms with the same 3-retry empty chain because the API request itself
was malformed.

Verified live via HTTP mock: pre-fix reproduced 5 api_calls/0.15s exit
'empty_response_exhausted'; post-fix 1 api_call/0.10s exit
'text_response(finish_reason=stop)'. Three-turn session flows cleanly
through the scenario. Full run_agent suite: 1242 passed (0 regressions,
2 pre-existing concurrent_interrupt failures unrelated).

feat(checkpoints): v2 single-store rewrite with real pruning + disk guardrails (#20709)
Replaces the per-directory shadow-repo design with a single shared shadow
git store at ~/.hermes/checkpoints/store/. Object DB is now deduplicated
across every working directory the agent has ever touched; a dozen
worktrees of the same project cost near-zero in additional disk.

Why
---
Pre-v2 design had three compounding problems that let ~/.hermes/checkpoints/
grow to multi-GB on active machines:

1. Each working directory got its own full shadow git repo — no object
   dedup across projects or across worktrees of the same project.
2. _prune() was a documented no-op: max_snapshots only limited the
   /rollback listing. Loose objects accumulated forever.
3. Defaults: enabled=True, auto_prune=False — users paid the disk cost
   without ever asking for /rollback.

Field report on a single workstation: 847 MB across 47 shadow repos,
mostly redundant clones of the hermes-agent source tree.

Changes
-------
- tools/checkpoint_manager.py: full rewrite. Single bare store, per-project
  refs (refs/hermes/<hash>), per-project indexes (store/indexes/<hash>),
  per-project metadata (store/projects/<hash>.json with workdir +
  created_at + last_touch). On first v2 init, any pre-v2 per-directory
  shadow repos are auto-migrated into legacy-<timestamp>/ so the new
  store starts clean. _prune() now actually rewrites the per-project ref
  to the last max_snapshots commits and runs git gc --prune=now. New
  _enforce_size_cap() drops oldest commits round-robin across projects
  when the store exceeds max_total_size_mb. _drop_oversize_from_index()
  filters any single file larger than max_file_size_mb out of the snapshot.
- hermes_cli/checkpoints.py: new 'hermes checkpoints' CLI
  (status / list / prune / clear / clear-legacy) for managing the store
  outside a session.
- hermes_cli/config.py: flipped defaults — enabled=False, max_snapshots=20,
  auto_prune=True. Added max_total_size_mb=500, max_file_size_mb=10.
  Tightened DEFAULT_EXCLUDES (added target/, *.so/*.dylib/*.dll,
  *.mp4/*.mov, *.zip/*.tar.gz, .worktrees/, .mypy_cache/, etc.).
- run_agent.py / cli.py / gateway/run.py: thread the new kwargs through
  AIAgent and the startup auto_prune hooks.
- Tests rewritten to match v2 storage while keeping backwards-compat
  coverage for the pre-v2 prune path (per-directory shadow repos under
  base/ are still swept correctly for anyone mid-migration).
- Docs updated: user-guide/checkpoints-and-rollback.md explains the
  shared store, new defaults, migration, and the new CLI;
  reference/cli-commands.md documents 'hermes checkpoints'.

E2E validated
-------------
- Legacy migration: pre-v2 shadow repos auto-archived into legacy-<ts>/.
- Object dedup: two projects with an identical shared.py blob resolve to
  7 total objects in the store (v1 would have stored the blob twice).
- max_snapshots=3 actually enforced: after 6 commits, list shows 3.
- Orphan prune: deleting a project's workdir + 'hermes checkpoints prune
  --retention-days 0' removes its ref, index, and metadata; GC reclaims
  the objects.
- max_file_size_mb=1 excludes a 2 MB weights.bin while keeping the
  tracked source code files.
- hermes checkpoints {status,prune,clear,clear-legacy} all work from the
  CLI without an agent running.

Breaking / migration
--------------------
No in-place data migration — legacy per-directory shadow repos are moved
into legacy-<timestamp>/ on first run. Old /rollback history is still
accessible by inspecting the archive with git; run
'hermes checkpoints clear-legacy' to reclaim the space when ready. Users
relying on /rollback must now set checkpoints.enabled=true (or pass
--checkpoints) explicitly.

20a4f79ed1 feat: provider modules — ProviderProfile ABC, 33 providers, fetch_models, transport single-path
Introduces providers/ package — single source of truth for every
inference provider. Adding a simple api-key provider now requires one
providers/<name>.py file with zero edits anywhere else.

What this PR ships:
- providers/ package (ProviderProfile ABC + 33 profiles across 4 api_modes)
- ProviderProfile declarative fields: name, api_mode, aliases, display_name,
  env_vars, base_url, models_url, auth_type, fallback_models, hostname,
  default_headers, fixed_temperature, default_max_tokens, default_aux_model
- 4 overridable hooks: prepare_messages, build_extra_body,
  build_api_kwargs_extras, fetch_models
- chat_completions.build_kwargs: profile path via _build_kwargs_from_profile,
  legacy flag path retained for lmstudio/tencent-tokenhub (which have
  session-aware reasoning probing that doesn't map cleanly to hooks yet)
- run_agent.py: profile path for all registered providers; legacy path
  variable scoping fixed (all flags defined before branching)
- Auto-wires: auth.PROVIDER_REGISTRY, models.CANONICAL_PROVIDERS,
  doctor health checks, config.OPTIONAL_ENV_VARS, model_metadata._URL_TO_PROVIDER
- GeminiProfile: thinking_config translation (native + openai-compat nested)
- New tests/providers/ (79 tests covering profile declarations, transport
  parity, hook overrides, e2e kwargs assembly)

Deltas vs original PR (salvaged onto current main):
- Added profiles: alibaba-coding-plan, azure-foundry, minimax-oauth
  (were added to main since original PR)
- Skipped profiles: lmstudio, tencent-tokenhub stay on legacy path (their
  reasoning_effort probing has no clean hook equivalent yet)
- Removed lmstudio alias from custom profile (it's a separate provider now)
- Skipped openrouter/custom from PROVIDER_REGISTRY auto-extension
  (resolve_provider special-cases them; adding breaks runtime resolution)
- runtime_provider: profile.api_mode only as fallback when URL detection
  finds nothing (was breaking minimax /v1 override)
- Preserved main's legacy-path improvements: deepseek reasoning_content
  preserve, gemini Gemma skip, OpenRouter response caching, Anthropic 1M
  beta recovery, etc.
- Kept agent/copilot_acp_client.py in place (rejected PR's relocation —
  main has 7 fixes landed since; relocation would revert them)
- _API_KEY_PROVIDER_AUX_MODELS alias kept for backward compat with existing
  test imports

c46bc92949 fix(run_agent): use aux provider for compression context length lookup
Each auxiliary model must be resolved with its own provider so that
provider-specific paths (e.g. Bedrock static table, OpenRouter API)
are invoked for the correct client, not inherited from the main model.

When the main model is Bedrock, passing self.provider unconditionally
to get_model_context_length() for the aux model caused the Bedrock
static table hard-intercept (step 1b) to fire for non-Bedrock models,
returning BEDROCK_DEFAULT_CONTEXT_LENGTH=128K instead of the model's
real context window — triggering a false compression warning every session.

Fix: pass _aux_cfg_provider when explicitly set, falling back to
self.provider only when the aux provider is unset or "auto".

efe1cb00c8 fix: prevent stale reasoning from being reused across turns
The reasoning-box extraction loop in run_conversation() walked backwards
through the entire message history looking for any assistant message
with a non-empty 'reasoning' field.  When the current turn produced
no reasoning (e.g. the provider returned reasoning_content=null for a
trivial response), the loop walked past the current turn and showed
reasoning from a prior turn — stale text from minutes or hours ago
displayed as if it belonged to the current reply.

Fix: stop the walk at the user message that started the current turn.
That picks the most recent reasoning WITHIN the turn (correct for
tool-calling turns where reasoning lands on the tool-call step and
the final-answer step has reasoning=None — common on Claude thinking,
DeepSeek v4, Codex Responses), and returns None cleanly when the
current turn genuinely had no reasoning.

fix(agent): stateful streaming scrubber for reasoning-block leaks (#17924) (#20184)
* revert(gateway): remove stale-code self-check and auto-restart

Removes the _detect_stale_code / _trigger_stale_code_restart mechanism
introduced in #17648 and iterated in #19740. On every incoming message
the gateway compared the boot-time git HEAD SHA to the current SHA on
disk, and if they differed it would reply with

    Gateway code was updated in the background --
    restarting this gateway so your next message runs
    on the new code. Please retry in a moment.

and then kick off a graceful restart. This is unwanted behaviour:
users who run a long-lived gateway and do their own ad-hoc git
operations on the checkout end up with their chat interrupted and
the current message dropped every time HEAD moves, with no way to
opt out.

If an operator really needs the old protection against stale
sys.modules after "hermes update", the SIGKILL-survivor sweep in
hermes update (hermes_cli/main.py, also tagged #17648) already
handles the supervisor-respawn case on its own.

Removed:
  gateway/run.py:
    - _STALE_CODE_SENTINELS, _GIT_SHA_CACHE_TTL_SECS
    - _read_git_head_sha(), _compute_repo_mtime() module helpers
    - class-level _boot_wall_time / _boot_repo_mtime / _boot_git_sha /
      _stale_code_restart_triggered defaults
    - __init__ boot-snapshot block (_boot_*, _cached_current_sha*,
      _repo_root_for_staleness, _stale_code_notified)
    - _current_git_sha_cached(), _detect_stale_code(),
      _trigger_stale_code_restart() methods
    - stale-code check + user-facing restart notice at the top of
      _handle_message()
  tests/gateway/test_stale_code_self_check.py (deleted, 412 lines)

No new logic added. Zero remaining references to any removed
symbol. Gateway test suite passes the same 4589 tests it passed
before; the 3 pre-existing unrelated failures (discord free-channel,
feishu bot admission, teams typing) are unchanged by this commit.

* fix(agent): stateful streaming scrubber for reasoning-block leaks (#17924)

Per-delta _strip_think_blocks ran at _fire_stream_delta and destroyed
downstream state. When MiniMax-M2.7 / DeepSeek / Qwen3 streamed a tag
split across deltas (delta1='<think>', delta2='Let me check'), the
regex case-2 match erased delta1 entirely, so CLI/gateway state
machines never learned a block was open and leaked delta2 as content.
Raw consumers (ACP, api_server, TTS) had no downstream defense at all.

Replace the per-delta regex with a stateful StreamingThinkScrubber
that survives delta boundaries:
  - Closed <tag>X</tag> pairs always stripped (matches _strip_think_blocks
    case 1).
  - Unterminated open at block boundary enters a block; content
    discarded until close tag arrives.  At end-of-stream, held
    content is dropped.
  - Orphan close tags stripped without boundary gating.
  - Partial tags at delta boundaries held back until resolved.
  - Block-boundary rule (start-of-stream, after \n, or
    whitespace-only since last \n) preserves prose that mentions
    tag names.

Reset at turn start alongside the existing context scrubber; flush at
turn end so a benign '<' held back at end-of-stream reaches the UI.

E2E-verified on live OpenRouter->MiniMax-m2 streams: closed pairs
strip cleanly, first word of post-block content is preserved, pure
content passes through unchanged.  Stefan's screenshot case (#17924)
— 'Let me check' getting chopped to ' me check' — no longer happens.

Final _strip_think_blocks calls on completed strings (final_response,
replay, compression) are preserved; only the streaming per-delta call
site switched to the scrubber.

28f4d6db63 fix(tool-schemas): reactive strip of pattern/format on llama.cpp grammar 400s
MCP servers commonly emit JSON Schema `pattern` (e.g. `\\d{4}-\\d{2}-\\d{2}`
for date-time params) and `format` keywords. llama.cpp's
`json-schema-to-grammar` converter rejects regex escape classes
(\\d/\\w/\\s) and most format values, returning HTTP 400
"parse: error parsing grammar: unknown escape at \\d" — the whole request
fails.

Cloud providers (OpenAI, Anthropic, OpenRouter, Gemini) accept these
keywords fine and use them as prompting hints. Stripping unconditionally
loses useful hints for every cloud user to fix a llama.cpp-only bug.

Approach: classify the llama.cpp grammar-parse 400 in the error
classifier, and on match do a one-shot in-place strip of pattern/format
from `self.tools`, then retry. Follows the existing
`thinking_signature` recovery pattern. Cloud users hit zero overhead;
llama.cpp users pay one failed request per session.

Changes
- agent/error_classifier.py: new `FailoverReason.llama_cpp_grammar_pattern`
  + narrow HTTP-400 branch matching "error parsing grammar",
  "json-schema-to-grammar", or "unable to generate parser ... template".
- tools/schema_sanitizer.py: new `strip_pattern_and_format()` helper —
  reactive, walks schema nodes, skips property names (search_files.pattern
  survives). Returns strip count for logging.
- run_agent.py: new one-shot recovery block in the retry loop. Strips,
  logs, continues. Falls through to normal retry if nothing to strip.
- tests: 4 classifier tests (3 variants + 1 non-400 negative), 7 strip
  tests including the property-name preservation and idempotency checks.

fbc477df71 fix(run_agent): acquire lock in IterationBudget.used property
The `used` property was reading `self._used` without holding the lock,
while `consume()`, `refund()`, and `remaining` all properly acquire
`self._lock` before accessing `_used`. This means a concurrent call to
`used` during `consume()` or `refund()` could observe a partially-
updated value, leading to incorrect iteration budget metrics reported
to the gateway, or in extreme cases a ValueError from CPython's list
implementation when the internal array resizes during iteration.

Fix: acquire the lock in `used` just like `remaining` does.

52882dade6 fix(agent): include name field on every role:tool message for Gemini compatibility (#16478)
Gemini's OpenAI-compatibility endpoint strictly requires the `name` field
on `role: tool` messages — it returns HTTP 400 ("Request contains an
invalid argument") when the function name is missing. OpenAI/Anthropic/
ollama tolerate the absence, so the gap stays invisible until the
conversation accumulates a tool turn and the user routes it through Gemini
(direct API or via ollama-cloud proxy).

Fix: add a `_get_tool_call_name_static()` helper alongside the existing
`_get_tool_call_id_static()`, and populate `name` at every site that
constructs a `role: tool` message — the pre-call sanitizer stub, the
tool-call args repair marker, both interrupt-skip paths, both
result-append paths (parallel + sequential), the invalid-tool-name
recovery, the invalid-JSON-args recovery, and the exception fallback.

Each call site was already in scope of the function name (`function_name`,
`skipped_name`, `name`, or a dict tool_call), so the change is local —
no new lookups, no behavior change for providers that already worked.

fix(self-improvement-loop): bump background-review budget to 16 and suppress status leaks (#19710)
The background memory/skill review fork had two user-visible issues:

1. max_iterations=8 was too tight for multi-step reviews. A review that
   needs to skill_view one or two candidate skills, add a memory entry,
   and patch a skill routinely blew the budget — surfacing an 'Iteration
   budget exhausted (8/8)' warning to the user and leaving the review
   half-finished.

2. Mid-review lifecycle messages leaked into the user's terminal past the
   existing quiet_mode + redirect_stdout/stderr guards. _emit_status and
   _emit_warning route through _vprint(force=True) -> _print_fn /
   status_callback, which bypass sys.stdout entirely. The stdout redirect
   only catches raw print() calls.

Changes:
- Bump the review fork's max_iterations from 8 to 16.
- Set review_agent.suppress_status_output = True on the fork. This
  short-circuits _vprint unconditionally so _emit_status/_emit_warning
  emissions (iteration-budget warnings, rate-limit retries, compression
  messages) never reach the user. The only user-visible output remains
  the compact final summary line ('💾 Self-improvement review: ...')
  which is printed via self._safe_print on the *main* agent (outside
  the fork's redirect/suppress scope).

Summarizer filter is already correct — _summarize_background_review_actions
only surfaces tool calls with data.get('success') is truthy, so failed
attempts and reasoning text never reach the summary line.

51dc98d314 fix(agent): detect Qwen3/Ollama inline thinking after tool calls
Ollama serves Qwen3 thinking inside the content field as <think>...</think>
blocks rather than in the API-level reasoning_content field.  This means
_has_structured was False for these responses, so an empty-looking reply
after a tool call triggered the nudge instead of the prefill continuation,
causing a double-response loop.

Fix: detect <think>/<thinking>/<reasoning> in final_response and:
  1. Skip the nudge when thinking is present (model is still reasoning)
  2. Include _has_inline_thinking in _has_structured so prefill kicks in

52c539d53a fix(agent): disable SDK retries on per-request OpenAI clients
Per-request OpenAI-wire clients (used by both non-streaming and
streaming chat-completions paths in _interruptible_api_call) should
not run the SDK's built-in retry loop: the agent's outer loop owns
retries with credential rotation, provider fallback, and backoff that
the SDK can't see.

Leaving SDK retries on (default 2) compounds with our outer retries
and lets a single hung provider request stretch to ~3x the per-call
timeout before our stale detector reports it.

Shared/primary clients and Anthropic / Bedrock paths are unaffected
(they don't go through here).

Salvage of #15811 core improvement — the timeout push-down in the
original PR required scaffolding that has since been refactored on
main, so only the max_retries=0 change is preserved.

fix(curator): only mark agent-created for background-review sediment (#19621)
Tighten the provenance semantics added in #19618: skills a user asks a
foreground agent to write via skill_manage(create) now stay invisible to
the curator. Only skills the background self-improvement review fork
sediments through skill_manage get the created_by=agent marker.

- tools/skill_provenance.py — new ContextVar module mirroring the
  _approval_session_key pattern: set_current_write_origin / reset /
  get / is_background_review. Default origin is 'foreground'; the
  review fork sets 'background_review'.
- run_agent.py — run_conversation() binds the ContextVar from
  self._memory_write_origin at the top of each call. The review fork
  runs on its own thread (fresh context), so foreground and review
  contexts never cross-contaminate.
- tools/skill_manager_tool.py — skill_manage(action='create') now
  only calls mark_agent_created() when is_background_review(). All
  other cases (foreground create, patch, edit, write_file, delete)
  continue as before.
- tests: test_skill_provenance.py (6 tests covering the ContextVar
  surface), split test_full_create_via_dispatcher into foreground
  vs. review-fork variants, curator status tests now mark-first.

Why: the agent routinely edits existing user skills on the user's
behalf; those writes must never flip provenance. And when a user
explicitly asks the foreground agent to create a skill, that skill
belongs to the user. The curator should only be cleaning up after
its own autonomous sediment from the review nudge loop.

Preflight compression can run synchronously before the first model call when a loaded session exceeds the active context threshold. Gateway users saw no visible progress while the compression LLM call was in flight, which can look like a dropped message during long compactions.\n\nEmit the existing lifecycle status through _emit_status before starting preflight compression so CLI, gateway, and WebUI status callbacks all get immediate feedback.\n\nAdds a regression assertion for the preflight path.

feat(openrouter): add response caching support (#19132)
Enable OpenRouter's response caching feature (beta) via X-OpenRouter-Cache
headers. When enabled, identical API requests return cached responses for
free (zero billing), reducing both latency and cost.

Configuration via config.yaml:
  openrouter:
    response_cache: true       # default: on
    response_cache_ttl: 300    # 1-86400 seconds

Changes:
- Add openrouter config section to DEFAULT_CONFIG (response_cache + TTL)
- Add build_or_headers() in auxiliary_client.py that builds attribution
  headers plus optional cache headers based on config
- Replace inline _OR_HEADERS dicts with build_or_headers() at all 5 sites:
  run_agent.py __init__, _apply_client_headers_for_base_url(), and
  auxiliary_client.py _try_openrouter() + _to_async_client()
- Add _check_openrouter_cache_status() method to AIAgent that reads
  X-OpenRouter-Cache-Status from streaming response headers and logs
  HIT/MISS status
- Document in cli-config.yaml.example
- Add 28 tests (22 unit + 6 integration)

13f344c5ce fix(agent): try fallback providers at init when primary credential pool is exhausted (#17929)
When a provider's credential pool has a single entry in 429-cooldown,
resolve_provider_client returns None and AIAgent.__init__ raises a
misleading RuntimeError suggesting the API key is missing — even when
valid fallback_providers are configured.

This patch makes __init__ iterate the fallback chain before raising,
mirroring the existing in-flight fallback logic in the request loop.
If a fallback resolves, the agent initializes against it and sets
_fallback_activated=True so _restore_primary_runtime can pick the
primary back up after cooldown.

fix: lazy session creation — defer DB row until first message (#18370)
Prevents ghost sessions from accumulating in state.db when the TUI/web
dashboard is opened and closed without sending a message.

Changes:
- run_agent.py: Add _ensure_db_session() gate method, called at
  run_conversation() entry. Remove eager create_session() from __init__.
  Handle compression rotation flag correctly.
- tui_gateway/server.py: Remove eager db.create_session() in
  _start_agent_build(). Add post-first-message pending_title re-apply.
- hermes_state.py: Extract _insert_session_row() shared helper (DRY).
  Add prune_empty_ghost_sessions() for one-time migration.
- cli.py: One-time ghost session prune on startup. Fix _pending_title
  to call _ensure_db_session() before set_session_title().
- hermes_cli/main.py: Guard TUI exit summary on message_count > 0.
- tests: Update test_860_dedup to call _ensure_db_session() before
  direct _flush_messages_to_session_db() calls.

Closes: ghost session clutter in hermes sessions list and web dashboard.

bfb704684e fix(deepseek): use non-empty reasoning_content placeholder for V4 Pro thinking mode
DeepSeek V4 Pro tightened thinking-mode validation and rejects empty-string
reasoning_content with HTTP 400:

    The reasoning content in the thinking mode must be passed back to the API.

run_agent.py injected "" at three fallback sites — the tool-call pad in
_build_assistant_message and both injection branches of
_copy_reasoning_content_for_api (cross-provider poison guard + unconditional
thinking pad). All three now emit " " (single space), which satisfies the
non-empty check on V4 Pro without leaking fabricated reasoning.

Also upgrades stale empty-string placeholders on replay: sessions persisted
before this change have reasoning_content="" pinned at creation time; when
the active provider enforces thinking-mode echo, the replay path now rewrites
"" -> " " so existing users don't 400 on their first V4 Pro turn after
updating. Non-thinking providers still round-trip "" verbatim.

Updates 9 existing assertions + adds 2 regression tests (stale-placeholder
upgrade, non-thinking verbatim preservation).

fix(compression): include system prompt + tool schemas in token estimates (#18265)
The user-visible /compress banner and the post-compression last_prompt_tokens
writeback both counted only the raw message transcript (chars/4). With a 15KB
system prompt and 30 tool schemas (~26KB), a 4-message transcript that looks
like ~45 tokens to the transcript-only estimator is really ~10.5K tokens of
request pressure — a 234x gap.

Two user-facing consequences:
- Banner shows 'Compressing … (~45 tokens)…' while compression is actually
  firing on 10K+ tokens of real pressure, confusing users about why
  compression triggered (reported by @codecovenant on X; #6217).
- Post-compression last_prompt_tokens writeback omits tool schemas, so the
  next should_compress() check compares real usage against a stale
  underestimate — compression triggers late, potentially past the model's
  context limit on small-context models (#14695).

Swap estimate_messages_tokens_rough() for estimate_request_tokens_rough()
at every user-visible banner and at the post-compression writeback.
estimate_request_tokens_rough() already existed for exactly this purpose
and includes system prompt + tool schemas.

Touched call sites:
- run_agent.py: post-compression last_prompt_tokens writeback, post-tool
  call should_compress() fallback when provider usage is missing
- cli.py: /compress banner + summary
- gateway/run.py: gateway /compress banner + summary
- tui_gateway/server.py: TUI /compress status + summary
- acp_adapter/server.py: ACP /compact before/after

Left intentionally alone:
- Session-hygiene fallback and the 'no agent' /status path in gateway/run.py
  — no agent instance is in scope to query for system prompt/tools, and the
  existing 30-50% overestimate wobble on hygiene is safety-accepted.
- Verbose-mode 'Request size' logging — informational only, already counts
  system prompt via api_messages[0].

Also relabels the feedback line from 'Rough transcript estimate' to
'Approx request size' so the metric label matches what it actually measures.

fix(agent): propagate ContextVars to concurrent tool worker threads (#18123)
Propagates ContextVars (notably `tools.approval._approval_session_key`) into concurrent tool worker threads via `copy_context().run` — mirrors `asyncio.to_thread` semantics.

Fixes approval-card cross-session misrouting in concurrent gateway traffic. Repro'd on Slack: session A's dangerous-command approval was delivered to channel B (@syahidfrd).

Salvages #16660 — core 4-LOC fix preserved, unrelated `tests/eval_018/` scope contamination dropped. Adds 5 regression guards including an AST-level source check on the real call site.

Closes #16660.

80a676658c fix(cli): surface self-improvement review summaries from bg thread
When the self-improvement background review fires after a turn, it runs
in a bg thread and emits a '  💾 <summary>' line to announce what it
saved to memory or skills. Two problems made this invisible to users
even when the review successfully modified a skill:

1. The print went through `_cprint` (prompt_toolkit's print_formatted_text)
   on a bg thread while the CLI's PromptSession was live. Direct
   print_formatted_text races with the input-area redraw and the line
   can land behind/above the prompt, scrolled off without the user
   seeing it.

2. The message said only '💾 Skill created.' / '💾 Memory updated'
   with no indication that the self-improvement loop was the one doing
   this. Users who did catch the line couldn't tell the background
   review from some other agent action.

Fixes:

- `_cprint` now detects when it's called from a non-app thread with a
  running prompt_toolkit Application, and routes through
  `run_in_terminal` via `loop.call_soon_threadsafe`. That pauses the
  input, prints the line above the prompt, and redraws — the normal
  prompt_toolkit contract for bg-thread output. Direct-print fallback
  preserved for the no-app / same-thread / import-error paths. Affects
  every bg-thread emission, not just the review summary (curator
  summaries and auxiliary failure prints benefit too).

- The summary now reads '  💾 Self-improvement review: <summary>' in
  both the CLI and the gateway `background_review_callback` path, so
  the origin is unambiguous.

Tests:
- New `tests/cli/test_cprint_bg_thread.py` covers all five routing
  branches (no app, app-not-running, cross-thread schedule, same-thread
  direct, app-loop-attribute-error, import-error).
- New case in `tests/run_agent/test_background_review.py` asserts the
  attributed prefix shows up in both `_safe_print` and
  `background_review_callback`.

Live E2E: exercised _cprint from a bg thread inside a real Application
event loop; confirmed get_app_or_none() sees the app, call_soon_threadsafe
schedules run_in_terminal, and the inner _pt_print runs.

feat(kanban): durable multi-profile collaboration board (#17805)
Salvage of PR #16100 onto current main (after emozilla's #17514 fix
that unblocks plugin Pydantic body validation). History preserved on
the standing `feat/kanban-standing` branch; this squashes the 22
iterative commits into one clean landing.

What this lands:
- SQLite kernel (hermes_cli/kanban_db.py) — durable task board with
  tasks, task_links, task_runs, task_comments, task_events,
  kanban_notify_subs tables. WAL mode, atomic claim via CAS,
  tenant-namespaced, skills JSON array per task, max-runtime timeouts,
  worker heartbeats, idempotency keys, circuit breaker on repeated
  spawn failures, crash detection via /proc/<pid>/status, run history
  preserved across attempts.
- Dispatcher — runs inside the gateway by default
  (`kanban.dispatch_in_gateway: true`). Ticks every 60s, reclaims
  stale claims, promotes ready tasks, spawns `hermes -p <assignee>
  chat -q "work kanban task <id>"` with HERMES_KANBAN_TASK +
  HERMES_KANBAN_WORKSPACE env. Auto-loads `--skills kanban-worker`
  plus any per-task skills. Health telemetry warns on stuck ready
  queue.
- Structured tool surface (tools/kanban_tools.py) — 7 tools
  (kanban_show, kanban_complete, kanban_block, kanban_heartbeat,
  kanban_comment, kanban_create, kanban_link). Gated on
  HERMES_KANBAN_TASK via check_fn so zero schema footprint in normal
  sessions.
- System-prompt guidance (agent/prompt_builder.py KANBAN_GUIDANCE)
  injected only when kanban tools are active.
- Dashboard plugin (plugins/kanban/dashboard/) — Linear-style board
  UI: triage/todo/ready/running/blocked/done columns, drag-drop,
  inline create, task drawer with markdown, comments, run history,
  dependency editor, bulk ops, lanes-by-profile grouping, WS-driven
  live refresh. Matches active dashboard theme via CSS variables.
- CLI — `hermes kanban init|create|list|show|assign|link|unlink|
  claim|comment|complete|block|unblock|archive|tail|dispatch|context|
  init|gc|watch|stats|notify|log|heartbeat|runs|assignees` +
  `/kanban` slash in-session.
- Worker + orchestrator skills (skills/devops/kanban-worker +
  kanban-orchestrator) — pattern library for good summary/metadata
  shapes, retry diagnostics, block-reason examples, fan-out patterns.
- Per-task force-loaded skills — `--skill <name>` (repeatable),
  stored as JSON, threaded through to dispatcher argv as one
  `--skills X` pair per skill alongside the built-in kanban-worker.
  Dashboard + CLI + tool parity.
- Deprecation of standalone `hermes kanban daemon` — stub exits 2
  with migration guidance; `--force` escape hatch for headless hosts.
- Docs (website/docs/user-guide/features/kanban.md + kanban-tutorial.md)
  with 11 dashboard screenshots walking through four user stories
  (Solo Dev, Fleet Farming, Role Pipeline, Circuit Breaker).
- Tests (251 passing): kernel schema + migration + CAS atomicity,
  dispatcher logic, circuit breaker, crash detection, max-runtime
  timeouts, claim lifecycle, tenant isolation, idempotency keys, per-
  task skills round-trip + validation + dispatcher argv, tool surface
  (7 tools × round-trip + error paths), dashboard REST (CRUD + bulk
  + links + warnings), gateway-embedded dispatcher (config gate, env
  override, graceful shutdown), CLI deprecation stub, migration from
  legacy schemas.

Gateway integration:
- GatewayRunner._kanban_dispatcher_watcher — new asyncio background
  task, symmetric with _kanban_notifier_watcher. Runs dispatch_once
  via asyncio.to_thread so SQLite WAL never blocks the loop. Sleeps
  in 1s slices for snappy shutdown. Respects HERMES_KANBAN_DISPATCH_IN_GATEWAY=0
  env override for debugging.
- Config: new `kanban` section in DEFAULT_CONFIG with
  `dispatch_in_gateway: true` (default) + `dispatch_interval_seconds: 60`.
  Additive — no \_config_version bump needed.

Forward-compat:
- workflow_template_id / current_step_key columns on tasks (v1 writes
  NULL; v2 will use them for routing).
- task_runs holds claim machinery (claim_lock, claim_expires,
  worker_pid, last_heartbeat_at) so multi-attempt history is first-
  class from day one.

Closes #16102.

76edc40ab0 fix(agent): extend thinking-mode reasoning_content pad to Kimi/Moonshot
Builds on #16855 (@lsdsjy) which fixed DeepSeek v4 reasoning_content
replay via model_extra fallback + capturing tool_calls at method entry.
Kimi / Moonshot thinking mode enforces the same echo-back contract and
hits the same 400 when a tool-call turn is persisted without
reasoning_content.

- _build_assistant_message: pad branch now uses _needs_thinking_reasoning_pad()
  (DeepSeek OR Kimi) instead of _needs_deepseek_tool_reasoning() alone.
- Extract _needs_thinking_reasoning_pad() and reuse it in
  _copy_reasoning_content_for_api so both sites share one predicate.
- tests/run_agent/test_deepseek_reasoning_content_echo.py: add
  TestBuildAssistantMessagePadsStrictProviders parametrized over DeepSeek
  (attr=None, attr-absent), Kimi (attr=None), Moonshot (via base_url),
  and an OpenRouter negative control that must NOT pad. Proven to fail
  2/5 cases on Kimi/Moonshot without this change.
- scripts/release.py: add AUTHOR_MAP entries for lsdsjy and season179.

fix(curator): seed defaults on update, create logs/curator dir, defer fire import (#17927)
Three fixes bundled for curator reliability on existing installs and
broken/partial installs:

1. run_agent.py: defer `import fire` into the __main__ block. `fire` is
   only used by `fire.Fire(main)` when running run_agent.py directly as
   a CLI — it is NOT needed for library usage. Importing it at module
   top made `from run_agent import AIAgent` from a daemon thread (e.g.
   the curator's forked review agent) crash with ModuleNotFoundError
   on broken/partial installs where `fire` isn't present.

2. hermes_cli/config.py: add version 22 → 23 migration that writes the
   `curator` + `auxiliary.curator` sections to config.yaml with their
   defaults, only filling keys the user hasn't overridden. Existing
   configs from before PR #16049 / the April 2026 `auxiliary.curator`
   unification had neither section on disk, so users couldn't see or
   edit the settings in their config.yaml (runtime deep-merge papered
   over it at read time, but the file never reflected reality).

3. hermes_cli/config.py: `ensure_hermes_home()` now pre-creates
   `~/.hermes/logs/curator/` alongside cron/sessions/logs/memories on
   every CLI launch. Managed-mode (NixOS) variant mkdir's it
   defensively after the activation-script existence checks, since the
   activation script may not know about this subpath.

4. agent/curator.py: `_reports_root()` mkdir's the dir at call time as
   belt-and-suspenders for entry paths that bypass both
   ensure_hermes_home() and the v23 migration (gateway-only installs,
   bare library use).

E2E validated in isolated HERMES_HOME: fresh install gets full defaults
seeded; partial-override config keeps user's `enabled: false` and
custom `interval_hours` while filling the missing keys; re-running the
migration is a no-op.

e0fa2cf972 fix(tools): isolate get_tool_definitions quiet_mode cache + dedup LCM injection (#17335)
Long-lived Gateway processes were sending duplicate tool names to
providers that enforce uniqueness:

  - DeepSeek:        'Tool names must be unique.'
  - Xiaomi MiMo:     'tools contains duplicate names: lcm_expand'
  - Moonshot/Kimi:   'function name lcm_grep is duplicated'

TUI was unaffected because TUI runs with quiet_mode=False and skips the
cache entirely.

Root cause (two layered bugs)
- model_tools.get_tool_definitions(quiet_mode=True) memoizes its result
  in _tool_defs_cache. The cache-hit path returned list(cached) (safe),
  but the FIRST uncached call stored and returned the SAME object.
  run_agent.py mutates self.tools (memory + LCM context-engine schemas)
  in-place, so the very first agent init in a Gateway process
  poisoned the cache, and every subsequent init appended LCM schemas
  again on top of the already-polluted list.
- run_agent.py's context-engine injection (lcm_grep / lcm_describe /
  lcm_expand) had no dedup, unlike the memory-tools injection right
  above it which already skips already-present names.

Fix (defense in depth, per the issue's suggested fix)
- model_tools.get_tool_definitions: on the uncached branch, cache the
  computed list but return list(result) to the caller. Same pattern as
  the cache-hit path.
- run_agent.py: build _existing_tool_names from self.tools and skip
  schemas whose names are already present, mirroring the memory-tools
  block. This also defends against plugin paths that may register the
  same schemas via ctx.register_tool().

Tests (tests/test_get_tool_definitions_cache_isolation.py)
- test_first_uncached_call_returns_fresh_list \u2014 pins the fix; without
  it, first-call alias caused all the symptoms.
- test_cache_hit_returns_fresh_list \u2014 pre-existing behavior stays.
- test_caller_mutation_does_not_poison_cache \u2014 simulates run_agent
  appending lcm_grep / lcm_expand to the returned list and asserts the
  next call doesn't see them.
- test_repeated_caller_mutation_does_not_accumulate \u2014 reproduces the
  long-lived Gateway accumulation pattern across 5 agent inits.
- test_non_quiet_mode_does_not_use_cache \u2014 sanity, explains why TUI
  was fine.

5/5 pass on the new file; 23/23 still pass on tests/test_model_tools.py.

0dd373ec43 fix(context): honor model.context_length for Ollama num_ctx and all display paths
When a user sets model.context_length in config.yaml, the value was only
used for Hermes' internal compression decisions (context_compressor) but
NOT for Ollama's num_ctx parameter. Ollama auto-detects context from GGUF
metadata (often 256K+) and allocates that much VRAM regardless of the
user's config — causing OOM on smaller GPUs like the P100 (16GB).

Root cause: two separate context values existed independently:
  - context_compressor.context_length = config value (e.g. 65536) ✓
  - _ollama_num_ctx = GGUF metadata value (e.g. 256000) ✗ ignored config

Changes:

1. Cap Ollama num_ctx to config context_length (run_agent.py)
   When model.context_length is explicitly set and no explicit
   ollama_num_ctx override exists, cap the auto-detected GGUF value
   to the user's context_length. This is the core fix — it prevents
   Ollama from allocating more VRAM than the user budgeted.

2. Pass config_context_length through all secondary call sites
   Several paths called get_model_context_length() without the config
   override, falling through to the 256K default fallback:
   - cli.py: @-reference expansion and /model switch display
   - gateway/run.py: @-reference expansion and /model switch display
   - tui_gateway/server.py: @-reference expansion
   - hermes_cli/model_switch.py: resolve_display_context_length()

3. Normalize root-level context_length in config (hermes_cli/config.py)
   _normalize_root_model_keys() now migrates root-level context_length
   into the model section, matching existing behavior for provider and
   base_url. Users who wrote `context_length: 65536` at the YAML root
   instead of under `model:` had it silently ignored.

4. Fix misleading comments (agent/model_metadata.py)
   DEFAULT_FALLBACK_CONTEXT is 256K (CONTEXT_PROBE_TIERS[0]), not 128K
   as two comments stated.

Tests: 3 new tests for root-level context_length normalization.
All existing context_length tests pass (96 tests).

400 'long context beta is not yet available for this subscription',
disable the beta for the rest of the session, rebuild the client, and
retry once.

Addresses #17680 (thanks @JayGwod for the clean reproduction) without
forcing every OAuth user off the 1M context window.

Changes:
- agent/error_classifier.py: new FailoverReason.oauth_long_context_beta_forbidden;
  pattern matches 400 + 'long context beta' + 'not yet available'. Narrow
  enough that the existing 429 tier-gate pattern keeps its own reason.
- agent/anthropic_adapter.py: _common_betas_for_base_url,
  build_anthropic_client, build_anthropic_kwargs gain drop_context_1m_beta
  kwarg. Default=False (1M stays). OAuth OAUTH_ONLY_BETAS unchanged.
- agent/transports/anthropic.py: build_kwargs forwards the flag.
- run_agent.py: self._oauth_1m_beta_disabled flag, retry-once guard,
  recovery branch next to the image-shrink path. _rebuild_anthropic_client
  honors the flag. The main build_kwargs call site threads it through for
  fast-mode extra_headers.
- hermes_cli/doctor.py, hermes_cli/models.py: sibling OAuth /v1/models
  probes get the same reactive retry — previously they'd falsely report
  the Anthropic API as unreachable for affected subscriptions.

Tests: 2190 tests/agent/ + 94 adjacent integration tests pass. New unit
tests cover the classifier pattern (including the collision guard against
the 429 tier-gate) and the drop_context_1m_beta adapter behavior (default
keeps 1M, flag strips only 1M while preserving every other beta).

71c8ca17dc chore(salvage): strip duplicated/merge-corrupted blocks from PR #17664
Removes drive-by duplication that accumulated during the contributor
branch's multiple rebases. All runtime-benign (dict last-wins,
redefinition last-wins) but left dead source that would confuse
reviewers and maintainers.

Surgical in-place de-duplication (kept PR's intentional additions,
removed only the doubled copy):

* hermes_cli/auth.py: duplicate "gmi" + "azure-foundry" ProviderConfig
* hermes_cli/models.py: duplicate "gmi" entry in _PROVIDER_MODELS
* hermes_cli/config.py: duplicate NOTION/LINEAR/AIRTABLE/TENOR skill env
  block + duplicate get_custom_provider_context_length definition
* hermes_cli/gateway.py: duplicate _setup_yuanbao
* gateway/platforms/base.py: duplicate is_host_excluded_by_no_proxy
* gateway/platforms/telegram.py: duplicate delete_message
* gateway/stream_consumer.py: duplicate _should_send_fresh_final and
  _try_fresh_final
* gateway/run.py: duplicate _parse_reasoning_command_args /
  _resolve_session_reasoning_config / _set_session_reasoning_override,
  duplicate "Drain silently when interrupted" interrupt check
* run_agent.py: duplicate HERMES_AGENT_HELP_GUIDANCE append, duplicate
  codex_message_items capture, duplicate custom_providers resolution
* tools/approval.py: duplicate HARDLINE_PATTERNS section and duplicate
  hardline call in check_dangerous_command
* tools/mcp_tool.py: duplicate _orphan_stdio_pids module-level decl
* cron/scheduler.py: duplicate "not configured/enabled" check — kept
  the new early-rejection, removed the stale late-path copy

Full-file resets to origin/main (all PR additions were duplicates of

feat(gateway): refine Platform._missing_ and platform-connected dispatch

Restricts plugin-name acceptance to bundled plugin scan + registry
(no arbitrary string -> enum-pollution), pulls per-platform connectivity
checks into a _PLATFORM_CONNECTED_CHECKERS lambda map with a clean
_is_platform_connected method, and adds tests covering the checker map,
plugin platform interface, and IRC setup wizard.

e464cde58f feat: final platform plugin parity — webhook delivery, platform hints, docs
Closes remaining functional gaps and adds documentation.

webhook.py: Cross-platform delivery now checks the plugin registry
  for unknown platform names instead of hardcoding 15 names in a tuple.
  Plugin platforms can receive webhook-routed deliveries.

prompt_builder: Platform hints (system prompt LLM guidance) now fall
  back to the plugin registry's platform_hint field. Plugin platforms
  can tell the LLM 'you're on IRC, no markdown.'

PlatformEntry: Added platform_hint field for LLM guidance injection.

IRC adapter: Added acquire_scoped_lock/release_scoped_lock in
  connect/disconnect to prevent two profiles from using the same IRC
  identity. Added platform_hint for IRC-specific LLM guidance.

Removed dead token-empty-warning extension for plugin platforms
  (plugin adapters handle their own env vars via check_fn).

website/docs/developer-guide/adding-platform-adapters.md:
  - Added 'Plugin Path (Recommended)' section with full code examples,
    PLUGIN.yaml template, config.yaml examples, and a table showing all
    18 integration points the plugin system handles automatically
  - Renamed built-in checklist to clarify it's for core contributors

gateway/platforms/ADDING_A_PLATFORM.md:
  - Added Plugin Path section pointing to the reference implementation
    and full docs guide
  - Clarified built-in path is for core contributors only

a7fb79efb2 fix(agent): spawn OpenRouter pre-warm thread only once per process
Each AIAgent.__init__() was unconditionally starting a daemon thread to
pre-warm the OpenRouter model metadata cache.  In gateway mode a new
AIAgent is created for every incoming message, so one OS thread leaked
per request.  After ~1 000 messages the process hit the Linux thread
limit and raised RuntimeError: can't start new thread for all subsequent
requests.

Add a module-level threading.Event (_openrouter_prewarm_done) that is
set before the thread is started.  Subsequent AIAgent instantiations
skip the spawn entirely; fetch_model_metadata() is cached for 1 hour so
the single background call is sufficient.

feat(memory): notify providers on mid-process session_id rotation (#17409)
Fixes #6672

Memory providers now receive on_session_switch() whenever AIAgent.session_id
rotates mid-process — /resume, /branch, /reset, /new, and context
compression. Before this, providers that cached per-session state in
initialize() (Hindsight's _session_id, _document_id, accumulated
_session_turns, _turn_counter) kept writing into the old session's
record after the agent had moved on.

MemoryProvider ABC
------------------
- New optional hook on_session_switch(new_session_id, *,
  parent_session_id='', reset=False, **kwargs) with no-op default for
  backward compat. reset=True signals /reset or /new — providers should
  flush accumulated per-session buffers. reset=False for /resume,
  /branch, compression where the logical conversation continues.

MemoryManager
-------------
- on_session_switch() fans the hook out to every registered provider.
  Isolated try/except per provider — one bad provider can't block others.
- Empty/None new_session_id is a no-op to avoid corrupting provider state
  during shutdown paths.

run_agent.py
------------
- _sync_external_memory_for_turn now passes session_id=self.session_id
  into sync_all() and queue_prefetch_all(). Providers with defensive
  session_id updates in sync_turn (Hindsight already had this at
  plugins/memory/hindsight/__init__.py:1199) now actually receive the
  current id.
- Compression block at ~L8884 already notified the context engine of
  the rollover; now also calls
  _memory_manager.on_session_switch(reason='compression').

cli.py
------
- new_session() fires reset=True, reason='new_session' so providers
  flush buffers.
- _handle_resume_command fires reset=False, reason='resume' with the
  previous session as parent_session_id.
- _handle_branch_command fires reset=False, reason='branch' with the
  parent session_id already captured for the DB parent link.

gateway/run.py
--------------
- _handle_resume_command now evicts the cached AIAgent, mirroring
  /branch and /reset. The next message rebuilds a fresh agent whose
  memory provider initialize() runs with the correct session_id —
  matches the pattern the gateway already uses for provider state
  cross-session transitions.

Hindsight reference implementation
----------------------------------
- plugins/memory/hindsight/__init__.py adds on_session_switch that:
  updates _session_id, mints a fresh _document_id (prevents
  vectorize-io/hindsight#1303 overwrite), and clears _session_turns /
  _turn_counter / _turn_index so in-flight batches don't flush under
  the new document id. parent_session_id only overwritten when provided
  (avoids clobbering on a bare switch).

Tests
-----
- tests/agent/test_memory_session_switch.py: new dedicated file. ABC
  default no-op, manager fan-out, failure isolation, empty-id no-op,
  session_id propagation through sync_all/queue_prefetch_all, Hindsight
  state transitions for every reset/non-reset case, parent preservation.
- tests/cli/test_branch_command.py: new test verifying /branch fires
  the hook with correct parent_session_id + reset=False + reason.
- tests/gateway/test_resume_command.py: new test verifying /resume
  evicts the cached agent.
- tests/run_agent/test_memory_sync_interrupted.py: updated existing
  assertions to account for the session_id kwarg on sync_all and
  queue_prefetch_all.

E2E verified (real imports, tmp HERMES_HOME):
- /resume: session_id updates, doc_id fresh, buffers cleared, parent set
- /branch: session_id forks, parent links to original
- /new: reset=True clears accumulated state
- compression: reason='compression' propagated, lineage preserved
- Empty id: no-op, state preserved
- Legacy provider without on_session_switch: no crash

comment by @kidonng extending coverage to compression.

fix(minimax): enable Anthropic prompt caching for MiniMax's own models (#17425)
MiniMax's /anthropic endpoint documents cache_control support (0.1x read
pricing, 5-min TTL) for MiniMax-M2.7, M2.5, M2.1, M2. PR #12846 gated
third-party Anthropic-wire caching on 'claude' in model name, which left
MiniMax's own model family re-paying full input tokens every turn.

Opt in explicitly via provider id (minimax / minimax-cn) or host match
(api.minimax.io / api.minimaxi.com). Narrow allowlist mirroring the
existing Qwen/Alibaba branch below; leaves room for a capability-based
surface (ProviderConfig.supports_anthropic_cache) if a third provider
needs it.

Closes #17332

refactor(config): migrate remaining 33 cfg_get call sites (#17311)
Completes the cfg_get migration started in PR #17304. Covers the
remaining hermes_cli/ and plugins/ config-access sites that the first
PR intentionally left opportunistic.

Migrated (33 sites across 14 files):

  hermes_cli/setup.py            13 sites  (terminal.*, agent.*, display.*, compression.*, tts.*)
  hermes_cli/tools_config.py      7 sites  (tts.*, browser.*, web.*, platform_toolsets.*)
  hermes_cli/plugins_cmd.py       3 sites  (plugins.*, memory.*, context.*)
  plugins/memory/honcho/cli.py    3 sites  (hosts.*)
  hermes_cli/web_server.py        1 site   (dashboard.*)
  hermes_cli/skills_config.py     1 site   (platform_disabled)
  hermes_cli/plugins.py           1 site   (plugins.disabled)
  hermes_cli/status.py            1 site   (terminal.backend)
  hermes_cli/mcp_config.py        1 site   (mcp_servers.*)
  hermes_cli/webhook.py           1 site   (platforms.webhook)
  plugins/memory/__init__.py      1 site   (memory.provider)
  plugins/memory/hindsight/       1 site   (banks.hermes)
  plugins/memory/holographic/     1 site   (plugins.hermes-memory-store)
  run_agent.py                    1 site   (auxiliary.compression)

The helper supports non-literal keys too, so e.g.
  cfg.get('hosts', {}).get(HOST, {})
becomes
  cfg_get(cfg, 'hosts', HOST, default={})

Migration bugs caught and fixed during this PR:

1. An AST-based batch rewrite naïvely captured the first word token in
   a chain, which corrupted 'self._config.get(...).get(...)' into
   'self.cfg_get(_config, ...)' (dropping 'self.', creating a broken
   method call). Plugins/memory/hindsight caught it via its test suite.
   Fixed manually to 'cfg_get(self._config, ...)'.

2. Import-extension heuristic rewrote multi-line parenthesized imports
   ('from X import (\n  A,\n  B,\n)') as
   'from X import cfg_get, (' — syntactically broken. Fixed by inserting
   cfg_get as the first name inside the parentheses.

Combined with PR #17304, the cfg_get migration now covers:

  PR #17304 (first batch): 20 sites in tools/ + gateway/
  PR #17317 (this one):    33 sites in hermes_cli/ + plugins/ + run_agent.py

Total: 53 sites migrated. Remaining ~8 sites are either:
  - Function-call chains (e.g. '_load_stt_config().get(...).get(...)')
    that would need double-evaluation or a local binding to migrate
    cleanly — intentionally deferred.
  - JSON response-navigation (e.g. 'response_data.get('data',{}).get('web'))
    which is unrelated to config access and shouldn't use cfg_get.

Verified:
- 412/412 tests/plugins/ pass (including the hindsight test that caught
  the self.X regex bug before commit)
- 3181/3189 tests/hermes_cli/ pass (8 pre-existing failures on main,
  verified by git-stash comparison)
- Live 'hermes status' and 'hermes config' render correctly (exercise
  the migrated terminal.backend, tts.provider, browser.cloud_provider,
  compression.threshold, display.tool_progress sites)
- Live 'hermes chat': 1 turn + /quit, zero errors in 11-line log window

No semantic changes — cfg_get was already proven to be a 1:1 match for
the original .get("X",{}).get("Y",default) pattern in PR #17304.

feat(review): active-update bias, loaded-skill-first, support-file variants (#17213)
The background skill-review prompts (_SKILL_REVIEW_PROMPT and the **Skills**
half of _COMBINED_REVIEW_PROMPT) steered the reviewer toward passive
behavior — most passes concluded 'Nothing to save.' even when the session
produced real lessons. User-preference corrections (style, format,
legibility, verbosity) were especially lost: they were read as memory
signals only, so skills never carried the fix.

This rewrite changes the stance:

- **Active-update bias.** The reviewer now treats inaction as a missed
  learning opportunity. 'Nothing to save.' remains an explicit escape
  but is no longer framed as the most-common outcome.

- **User-preference corrections are first-class skill signals.** Style,
  tone, format, legibility, verbosity complaints — and the actual
  phrasings users use ('stop doing X', 'this is too verbose', 'I hate
  when you Y', 'remember this') — now warrant patching the skill that
  governs the task, not just writing to memory.

- **Loaded-skill-first preference order.** When a skill was loaded via
  /skill-name or skill_view during the session, the reviewer patches
  THAT one first. It was in play; it's the right place.

- **Four-step ladder: patch-loaded → patch-umbrella → support-file →
  create.** Support files are explicitly enumerated as three kinds:
    * references/<topic>.md — session-specific detail OR condensed
      knowledge banks (quoted research, API docs excerpts, domain notes)
    * templates/<name>.<ext> — starter files to copy and modify
    * scripts/<name>.<ext>  — statically re-runnable actions

- **Name-veto for CREATE.** New skill names MUST be class-level — no PR
  numbers, error strings, codenames, library-alone names, or session
  artifacts ('fix-X / debug-Y / audit-Z-today'). If the proposed name
  only fits today's task, fall back to one of the patch/support-file
  options.

- **Memory scope clarified.** 'who the user is and what the current
  situation and state of your operations are' — MEMORY.md is
  situational/state, USER.md is identity/preferences.

- **Curator handoff.** Reviewer flags overlap; the background curator
  handles consolidation at scale. Single-session reviewer doesn't
  attempt umbrella-rebalancing.

Tests: tests/run_agent/test_review_prompt_class_first.py upgraded to
assert the new behavioral contracts (active bias, user-correction
signals, loaded-skill-first, support-file kinds, name-veto, memory
framing, curator handoff). 17 tests, all pass.
