fix(agent): repair CamelCase + _tool suffix tool-call emissions (#15124)
Claude-style and some Anthropic-tuned models occasionally emit tool
names as class-like identifiers: TodoTool_tool, Patch_tool,
BrowserClick_tool, PatchTool. These failed strict-dict lookup in
valid_tool_names and triggered the 'Unknown tool' self-correction
loop, wasting a full turn of iteration and tokens.

_repair_tool_call already handled lowercase / separator / fuzzy
matches but couldn't bridge the CamelCase-to-snake_case gap or the
trailing '_tool' suffix that Claude sometimes tacks on. Extend it
with two bounded normalization passes:

  1. CamelCase -> snake_case (via regex lookbehind).
  2. Strip trailing _tool / -tool / tool suffix (case-insensitive,
     applied twice so TodoTool_tool reduces all the way: strip
     _tool -> TodoTool, snake -> todo_tool, strip 'tool' -> todo).

Cheap fast-paths (lowercase / separator-normalized) still run first
so the common case stays zero-cost. Fuzzy match remains the last
resort unchanged.

Tests: tests/run_agent/test_repair_tool_call_name.py covers the
three original reports (TodoTool_tool, Patch_tool, BrowserClick_tool),
plus PatchTool, WriteFileTool, ReadFile_tool, write-file_Tool,
patch-tool, and edge cases (empty, None, '_tool' alone, genuinely
unknown names).

18 new tests + 17 existing arg-repair tests = 35/35 pass.

Closes #14784

1fc77f995b fix(agent): fall back on rate limit when pool has no rotation room
Extracts pool-rotation-room logic into `_pool_may_recover_from_rate_limit`
so single-credential pools no longer block the eager-fallback path on 429.

The existing check `pool is not None and pool.has_available()` lets
fallback fire only after the pool marks every entry as exhausted.  With
exactly one credential in the pool (the common shape for Gemini OAuth,
Vertex service accounts, and any personal-key setup), `has_available()`
flips back to True as soon as the cooldown expires — Hermes retries
against the same entry, hits the same daily-quota 429, and burns the
retry budget in a tight loop before ever reaching the configured
`fallback_model`.  Observed in the wild as 4+ hours of 429 noise on a
single Gemini key instead of falling through to Vertex as configured.

Rotation is only meaningful with more than one credential — gate on
`len(pool.entries()) > 1`.  Multi-credential pools keep the current
wait-for-rotation behaviour unchanged.

Fixes #11314.  Related to #8947, #10210, #7230.  Narrower scope than
open PRs #8023 (classifier change) and #11492 (503/529 credential-pool
bypass) — this addresses the single-credential 429 case specifically
and does not conflict with either.

Tests: 6 new unit tests in tests/run_agent/test_provider_fallback.py
covering (a) None pool, (b) single-cred available, (c) single-cred in
cooldown, (d) 2-cred available rotates, (e) multi-cred all cooling-down
falls back, (f) many-cred available rotates.  All 18 tests in the file
pass.

2cab8129d1 feat(copilot): add 401 auth recovery with automatic token refresh and client rebuild
When using GitHub Copilot as provider, HTTP 401 errors could cause
Hermes to silently fall back to the next model in the chain instead
of recovering. This adds a one-shot retry mechanism that:

1. Re-resolves the Copilot token via the standard priority chain
   (COPILOT_GITHUB_TOKEN -> GH_TOKEN -> GITHUB_TOKEN -> gh auth token)
2. Rebuilds the OpenAI client with fresh credentials and Copilot headers
3. Retries the failed request before falling back

The fix handles the common case where the gho_* OAuth token remains
valid but the httpx client state becomes stale (e.g. after startup
race conditions or long-lived sessions).

Key design decisions:
- Always rebuild client even if token string unchanged (recovers stale state)
- Uses _apply_client_headers_for_base_url() for canonical header management
- One-shot flag guard prevents infinite 401 loops (matches existing pattern
  used by Codex/Nous/Anthropic providers)
- No token exchange via /copilot_internal/v2/token (returns 404 for some
  account types; direct gho_* auth works reliably)

Tests: 3 new test cases covering end-to-end 401->refresh->retry,
client rebuild verification, and same-token rebuild scenarios.
Docs: Updated providers.md with Copilot auth behavior section.

fix(agent): retry on json.JSONDecodeError instead of treating it as a local validation error (#15107)
json.JSONDecodeError inherits from ValueError. The agent loop's
non-retryable classifier at run_agent.py ~L10782 treated any
ValueError/TypeError as a local programming bug and short-circuited
retry. Without a carve-out, a transient JSONDecodeError from a
provider that returned a malformed response body, a truncated stream,
or a router-layer corruption would fail the turn immediately.

Add JSONDecodeError to the existing UnicodeEncodeError exclusion
tuple so the classified-retry logic (which already handles 429/529/
context-overflow/etc.) gets to run on bad-JSON errors.

Tests (tests/run_agent/test_jsondecodeerror_retryable.py):
  - JSONDecodeError: NOT local validation
  - UnicodeEncodeError: NOT local validation (existing carve-out)
  - bare ValueError: IS local validation (programming bug)
  - bare TypeError: IS local validation (programming bug)
  - source-level assertion that run_agent.py still carries the carve-out
    (guards against accidental revert)

fix(tests): resolve 17 persistent CI test failures (#15084)
Make the main-branch test suite pass again. Most failures were tests
still asserting old shapes after recent refactors; two were real source
bugs.

Source fixes:
- tools/mcp_tool.py: _kill_orphaned_mcp_children() slept 2s on every
  shutdown even when no tracked PIDs existed, making test_shutdown_is_parallel
  measure ~3s for 3 parallel 1s shutdowns. Early-return when pids is empty.
- hermes_cli/tips.py: tip 105 was 157 chars; corpus max is 150.

Test fixes (mostly stale mock targets / missing fixture fields):
- test_zombie_process_cleanup, test_agent_cache: patch run_agent.cleanup_vm
  (the local name bound at import), not tools.terminal_tool.cleanup_vm.
- test_browser_camofox: patch tools.browser_camofox.load_config, not
  hermes_cli.config.load_config (the source module, not the resolved one).
- test_flush_memories_codex._chat_response_with_memory_call: add
  finish_reason, tool_call.id, tool_call.type so the chat_completions
  transport normalizer doesn't AttributeError.
- test_concurrent_interrupt: polling_tool signature now accepts
  messages= kwarg that _invoke_tool() passes through.
- test_minimax_provider: add _fallback_chain=[] to the __new__'d agent
  so switch_model() doesn't AttributeError.
- test_skills_config: SKILLS_DIR MagicMock + .rglob stopped working
  after the scanner switched to agent.skill_utils.iter_skill_index_files
  (os.walk-based). Point SKILLS_DIR at a real tmp_path and patch
  agent.skill_utils.get_external_skills_dirs.
- test_browser_cdp_tool: browser_cdp toolset was intentionally split into
  'browser-cdp' (commit 96b0f3700) so its stricter check_fn doesn't gate
  the whole browser toolset; test now expects 'browser-cdp'.
- test_registry: add tools.browser_dialog_tool to the expected
  builtin-discovery set (PR #14540 added it).
- test_file_tools TestPatchHints: patch_tool surfaces hints as a '_hint'
  key on the JSON payload, not inline '[Hint: ...' text.
- test_write_deny test_hermes_env: resolve .env via get_hermes_home() so
  the path matches the profile-aware denylist under hermetic HERMES_HOME.
- test_checkpoint_manager test_falls_back_to_parent: guard the walk-up
  so a stray /tmp/pyproject.toml on the host doesn't pick up /tmp as the
  project root.
- test_quick_commands: set cli.session_id in the __new__'d CLI so the
  alias-args path doesn't trip AttributeError when fuzzy-matching leaks
  a skill command across xdist test distribution.

fix(compress): don't reach into ContextCompressor privates from /compress (#15039)
Manual /compress crashed with 'LCMEngine' object has no attribute
'_align_boundary_forward' when any context-engine plugin was active.
The gateway handler reached into _align_boundary_forward and
_find_tail_cut_by_tokens on tmp_agent.context_compressor, but those
are ContextCompressor-specific — not part of the generic ContextEngine
ABC — so every plugin engine (LCM, etc.) raised AttributeError.

- Add optional has_content_to_compress(messages) to ContextEngine ABC
  with a safe default of True (always attempt).
- Override it in the built-in ContextCompressor using the existing
  private helpers — preserves exact prior behavior for 'compressor'.
- Rewrite gateway /compress preflight to call the ABC method, deleting
  the private-helper reach-in.
- Add focus_topic to the ABC compress() signature. Make _compress_context
  retry without focus_topic on TypeError so older strict-sig plugins
  don't crash on manual /compress <focus>.
- Regression test with a fake ContextEngine subclass that only
  implements the ABC (mirrors LCM's surface).

feat(agent): make API retry count configurable via agent.api_max_retries (#14730)
Closes #11616.

The agent's API retry loop hardcoded max_retries = 3, so users with
fallback providers on flaky primaries burned through ~3 × provider
timeout (e.g. 3 × 180s = 9 minutes) before their fallback chain got a
chance to kick in.

Expose a new config key:

    agent:
      api_max_retries: 3  # default unchanged

Set it to 1 for fast failover when you have fallback providers, or
raise it if you prefer longer tolerance on a single provider. Values
< 1 are clamped to 1 (single attempt, no retry); non-integer values
fall back to the default.

This wraps the Hermes-level retry loop only — the OpenAI SDK's own
low-level retries (max_retries=2 default) still run beneath this for
transient network errors.

Changes:
- hermes_cli/config.py: add agent.api_max_retries default 3 with comment.
- run_agent.py: read self._api_max_retries in AIAgent.__init__; replace
  hardcoded max_retries = 3 in the retry loop with self._api_max_retries.
- cli-config.yaml.example: documented example entry.
- hermes_cli/tips.py: discoverable tip line.
- tests/run_agent/test_api_max_retries_config.py: 4 tests covering
  default, override, clamp-to-one, and invalid-value fallback.

43de1ca8c2 refactor: remove _nr_to_assistant_message shim + fix flush_memories guard
NormalizedResponse and ToolCall now have backward-compat properties
so the agent loop can read them directly without the shim:

  ToolCall: .type, .function (returns self), .call_id, .response_item_id
  NormalizedResponse: .reasoning_content, .reasoning_details,
                      .codex_reasoning_items

This eliminates the 35-line shim and its 4 call sites in run_agent.py.

Also changes flush_memories guard from hasattr(response, 'choices')
to self.api_mode in ('chat_completions', 'bedrock_converse') so it
works with raw boto3 dicts too.

f4612785a4 refactor: collapse normalize_anthropic_response to return NormalizedResponse directly
3-layer chain (transport → v2 → v1) was collapsed to 2-layer in PR 7.
This collapses the remaining 2-layer (transport → v1 → NR mapping in
transport) to 1-layer: v1 now returns NormalizedResponse directly.

Before: adapter returns (SimpleNamespace, finish_reason) tuple,
  transport unpacks and maps to NormalizedResponse (22 lines).
After: adapter returns NormalizedResponse, transport is a
  1-line passthrough.

Also updates ToolCall construction — adapter now creates ToolCall
dataclass directly instead of SimpleNamespace(id, type, function).

d30ee2e545 refactor: unify transport dispatch + collapse normalize shims
Consolidate 4 per-transport lazy singleton helpers (_get_anthropic_transport,
_get_codex_transport, _get_chat_completions_transport, _get_bedrock_transport)
into one generic _get_transport(api_mode) with a shared dict cache.

Collapse the 65-line main normalize block (3 api_mode branches, each with
its own SimpleNamespace shim) into 7 lines: one _get_transport() call +
one _nr_to_assistant_message() shared shim. The shim extracts provider_data
fields (codex_reasoning_items, reasoning_details, call_id, response_item_id)
into the SimpleNamespace shape downstream code expects.

Wire chat_completions and bedrock_converse normalize through their transports
for the first time — these were previously falling into the raw
response.choices[0].message else branch.

Remove 8 dead codex adapter imports that have zero callers after PRs 1-6.

Transport lifecycle improvements:
- Eagerly warm transport cache at __init__ (surfaces import errors early)
- Invalidate transport cache on api_mode change (switch_model, fallback
  activation, fallback restore, transport recovery) — prevents stale
  transport after mid-session provider switch

run_agent.py: -32 net lines (11,988 -> 11,956).

c345ec9a63 fix(display): strip standalone tool-call XML tags from visible text
Port from openclaw/openclaw#67318. Some open models (notably Gemma
variants served via OpenRouter) emit tool calls as XML blocks inside
assistant content instead of via the structured tool_calls field:

  <function name="read_file"><parameter name="path">/tmp/x</parameter></function>
  <tool_call>{"name":"x"}</tool_call>
  <function_calls>[{...}]</function_calls>

Left unstripped, this raw XML leaked to gateway users (Discord, Telegram,
Matrix, Feishu, Signal, WhatsApp, etc.) and the CLI, since hermes-agent's
existing reasoning-tag stripper handled only <think>/<thinking>/<thought>
variants.

Extend _strip_think_blocks (run_agent.py) and _strip_reasoning_tags
(cli.py) to cover:
  * <tool_call>, <tool_calls>, <tool_result>
  * <function_call>, <function_calls>
  * <function name="..."> ... </function> (Gemma-style)

The <function> variant is boundary-gated (only strips when the tag sits
at start-of-line or after sentence punctuation AND carries a name="..."
attribute) so prose mentions like 'Use <function> declarations in JS'
are preserved. Dangling <function name="..."> with no close is
intentionally left visible — matches OpenClaw's asymmetry so a truncated
streaming tail still reaches the user.

Tests: 9 new cases in TestStripThinkBlocks (run_agent) + 9 in new file
tests/run_agent/test_strip_reasoning_tags_cli.py. Covers Qwen-style
<tool_call>, Gemma-style <function name="...">, multi-line payloads,
prose preservation, stray close tags, dangling open tags, and mixed
reasoning+tool_call content.

Note: this port covers the post-streaming final-text path, which is what
gateway adapters and CLI display consume. Extending the per-delta stream
filter in gateway/stream_consumer.py to hide these tags live as they
stream is a separate follow-up; for now users may see raw XML briefly
during a stream before the final cleaned text replaces it.

fix(streaming): silent retry when stream dies mid tool-call (#14151)
When the streaming connection dropped AFTER user-visible text was
delivered but a tool call was in flight, we stubbed the turn with a
'⚠ Stream stalled mid tool-call; Ask me to retry' warning — costing
an iteration and breaking the flow.  Users report this happening
increasingly often on long SSE streams through flaky provider routes.

Fix: in the existing inner stream-retry loop, relax the
deltas_were_sent short-circuit.  If a tool call was in flight
(partial_tool_names populated) AND the error is a transient connection
error (timeout, RemoteProtocolError, SSE 'connection lost', etc.),
silently retry instead of bailing out.  Fire a brief 'Connection
dropped mid tool-call; reconnecting…' marker so the user understands
the preamble is about to be re-streamed.

Researched how Claude Code (tombstone + non-streaming fallback),
OpenCode (blind Effect.retry wrapping whole stream), and Clawdbot
(4-way gate: stopReason==error + output==0 + !hadPotentialSideEffects)
handle this.  Chose the narrow Clawdbot-style gate: retry only when
(a) a tool call was actually in flight (otherwise the existing
stub-with-recovered-text is correct for pure-text stalls) and
(b) the error is transient.  Side-effect safety is automatic — no
tool has been dispatched within this single API call yet.

UX trade-off: user sees preamble text twice on retry (OpenCode-style).
Strictly better than a lost action with a 'retry manually' message.
If retries exhaust, falls through to the existing stub-with-warning
path so the user isn't left with zero signal.

Tests: 3 new tests in TestSilentRetryMidToolCall covering
(1) silent retry recovers tool call; (2) exhausted retries fall back
to stub; (3) text-only stalls don't trigger retry.  30/30 pass.

f0b763c74f fix(model-switch): drop stale provider from fallback chain and env after /model
Reported during the TUI v2 blitz test: switching from openrouter to
anthropic via `/model <name> --provider anthropic` appeared to succeed,
but the next turn kept hitting openrouter — the provider the user was
deliberately moving away from.

Two gaps caused this:

1. `Agent.switch_model` reset `_fallback_activated` / `_fallback_index`
   but left `_fallback_chain` intact. The chain was seeded from
   `fallback_providers:` at agent init for the *original* primary, so
   when the new primary returned 401 (invalid/expired Anthropic key),
   `_try_activate_fallback()` picked the old provider back up without
   informing the user. Prune entries matching either the old primary
   (user is moving away) or the new primary (redundant) whenever the
   primary provider actually changes.

2. `_apply_model_switch` persisted `HERMES_MODEL` but never updated
   `HERMES_INFERENCE_PROVIDER`. Any ambient re-resolution of the runtime
   (credential pool refresh, compressor rebuild, aux clients) falls
   through to that env var in `resolve_requested_provider`, so it kept
   reporting the original provider even after an in-memory switch.

Adds three regression tests: fallback-chain prune on primary change,
no-op on same-provider model swap, and env-var sync on explicit switch.

fix(cache): enable prompt caching for Qwen on OpenCode/OpenCode-Go/Alibaba (#13528)
Qwen models on OpenCode, OpenCode Go, and direct DashScope accept
Anthropic-style cache_control markers on OpenAI-wire chat completions,
but hermes only injected markers for Claude-named models. Result: zero
cache hits on every turn, full prompt re-billed — a community user
reported burning through their OpenCode Go subscription on Qwen3.6.

Extend _anthropic_prompt_cache_policy to return (True, False) — envelope
layout, not native — for the Alibaba provider family when the model name
contains 'qwen'. Envelope layout places markers on inner content blocks
(matching pi-mono's 'alibaba' cacheControlFormat) and correctly skips
top-level markers on tool-role messages (which OpenCode rejects).

Non-Qwen models on these providers (GLM, Kimi) keep their existing
behaviour — they have automatic server-side caching and don't need
client markers.

Upstream reference: pi-mono #3392 / #3393 documented this contract for
opencode-go Qwen models.

Adds 7 regression tests covering Qwen3.5/3.6/coder on each affected
provider plus negative cases for GLM/Kimi/OpenRouter-Qwen.

155b619867 fix(agent): normalize socks:// env proxies for httpx/anthropic
WSL2 / Clash-style setups often export ALL_PROXY=socks://127.0.0.1:PORT. httpx and the Anthropic SDK reject that alias and expect socks5://, so agent startup failed early with "Unknown scheme for proxy URL" before any provider request could proceed.

063bc3c1e2 fix(kimi): send max_tokens, reasoning_effort, and thinking for Kimi/Moonshot
Kimi/Moonshot endpoints require explicit parameters that Hermes was not
sending, causing 'Response truncated due to output length limit' errors
and inconsistent reasoning behavior.

Root cause analysis against Kimi CLI source (MoonshotAI/kimi-cli,
packages/kosong/src/kosong/chat_provider/kimi.py):

1. max_tokens: Kimi's API defaults to a very low value when omitted.
   Reasoning tokens share the output budget — the model exhausts it on
   thinking alone.  Send 32000, matching Kimi CLI's generate() default.

2. reasoning_effort: Kimi CLI sends this as a top-level parameter (not
   inside extra_body).  Hermes was not sending it at all because
   _supports_reasoning_extra_body() returns False for non-OpenRouter
   endpoints.

3. extra_body.thinking: Kimi CLI uses with_thinking() which sets
   extra_body.thinking={"type":"enabled"} alongside reasoning_effort.
   This is a separate control from the OpenAI-style reasoning extra_body
   that Hermes sends for OpenRouter/GitHub.  Without it, the Kimi gateway
   may not activate reasoning mode correctly.

Covers api.kimi.com (Kimi Code) and api.moonshot.ai/cn (Moonshot).

Tests: 6 new test cases for max_tokens, reasoning_effort, and
extra_body.thinking under various configs.

Catalog snapshots, config version literals, and enumeration counts are data
that changes as designed. Tests that assert on those values add no
behavioral coverage — they just break CI on every routine update and cost
engineering time to 'fix.'

Replace with invariants where one exists, delete where none does.

Deleted (pure snapshots):
- TestMinimaxModelCatalog (3 tests): 'MiniMax-M2.7 in models' et al
- TestGeminiModelCatalog: 'gemini-2.5-pro in models', 'gemini-3.x in models'
- test_browser_camofox_state::test_config_version_matches_current_schema
  (docstring literally said it would break on unrelated bumps)

Relaxed (keep plumbing check, drop snapshot):
- Xiaomi / Arcee / Kimi moonshot / Kimi coding / HuggingFace static lists:
  now assert 'provider exists and has >= 1 entry' instead of specific names
- HuggingFace main/models.py consistency test: drop 'len >= 6' floor

Dynamicized (follow source, not a literal):
- 3x test_config.py migration tests: raw['_config_version'] ==
  DEFAULT_CONFIG['_config_version'] instead of hardcoded 21

Fixed stale tests against intentional behavior changes:
- test_insights::test_gateway_format_hides_cost: name matches new behavior
  (no dollar figures); remove contradicting '$' in text assertion
- test_config::prefers_api_then_url_then_base_url: flipped per PR #9332;
  rename + update to base_url > url > api
- test_anthropic_adapter: relax assert_called_once() (xdist-flaky) to
  assert called — contract is 'credential flowed through'
- test_interrupt_propagation: add provider/model/_base_url to bare-agent
  fixture so the stale-timeout code path resolves

Fixed stale integration tests against opt-in plugin gate:
- transform_tool_result + transform_terminal_output: write plugins.enabled
  allow-list to config.yaml and reset the plugin manager singleton

Source fix (real consistency invariant):
- agent/model_metadata.py: add moonshotai/Kimi-K2.6 context length
  (262144, same as K2.5). test_model_metadata_has_context_lengths was
  correctly catching the gap.

Policy:
- AGENTS.md Testing section: new subsection 'Don't write change-detector
  tests' with do/don't examples. Reviewers should reject catalog-snapshot
  assertions in new tests.

Covers every test that failed on the last completed main CI run
(24703345583) except test_modal_sandbox_fixes::test_terminal_tool_present
+ test_terminal_and_file_toolsets_resolve_all_tools, which now pass both
alone and with the full tests/tools/ directory (xdist ordering flake that
resolved itself).

refactor(steer): simplify injection marker to 'User guidance:' prefix (#13340)
The mid-run steer marker was '[USER STEER (injected mid-run, not tool
output): <text>]'. Replaced with a plain two-newline-prefixed
'User guidance: <text>' suffix.

Rationale: the marker lives inside the tool result's content string
regardless of whether the tool returned JSON, plain text, an MCP
result, or a plugin result. The bracketed tag read like structured
metadata that some tools (terminal, execute_code) could confuse with
their own output formatting. A plain labelled suffix works uniformly
across every content shape we produce.

Behavior unchanged:
- Still injected into the last tool-role message's content.
- Still preserves multimodal (Anthropic) content-block lists by
  appending a text block.
- Still drained at both sites added in #12959 and #13205 — per-tool
  drain between individual calls, and pre-API-call drain at the top
  of each main-loop iteration.

Checked Codex's equivalent (pending_input / inject_user_message_without_turn
in codex-rs/core): they record mid-turn user input as a real role:user
message via record_user_prompt_and_emit_turn_item(). That's cleaner for
their Responses-API model but not portable to Chat Completions where
role alternation after tool_calls is strict. Embedding the guidance in
the last tool result remains the correct placement for us.

Validation: all 21 tests in tests/run_agent/test_steer.py pass.

fix(steer): drain pending steer before each API call, not just after tool execution (#13205)
When /steer is sent during an API call (model thinking), the steer text
sits in _pending_steer until after the next tool batch — which may never
come if the model returns a final response. In that case the steer is
only delivered as a post-run follow-up, defeating the purpose.

Add a pre-API-call drain at the top of the main loop: before building
api_messages, check _pending_steer and inject into the last tool result
in the messages list. This ensures steers sent during model thinking are
visible on the very next API call.

If no tool result exists yet (first iteration), the steer is restashed
for the post-tool drain to pick up — injecting into a user message would
break role alternation.

Three new tests cover the pre-API-call drain: injection into last tool
result, restash when no tool message exists, and backward scan past
non-tool messages.

fix(kimi): omit temperature entirely for Kimi/Moonshot models (#13157)
Kimi's gateway selects the correct temperature server-side based on the
active mode (thinking -> 1.0, non-thinking -> 0.6).  Sending any
temperature value — even the previously "correct" one — conflicts with
gateway-managed defaults.

Replaces the old approach of forcing specific temperature values (0.6
for non-thinking, 1.0 for thinking) with an OMIT_TEMPERATURE sentinel
that tells all call sites to strip the temperature key from API kwargs
entirely.

Changes:
- agent/auxiliary_client.py: OMIT_TEMPERATURE sentinel, _is_kimi_model()
  prefix check (covers all kimi-* models), _fixed_temperature_for_model()
  returns sentinel for kimi models.  _build_call_kwargs() strips temp.
- run_agent.py: _build_api_kwargs, flush_memories, and summary generation
  paths all handle the sentinel by popping/omitting temperature.
- trajectory_compressor.py: _effective_temperature_for_model returns None
  for kimi (sentinel mapped), direct client calls use kwargs dict to
  conditionally include temperature.
- mini_swe_runner.py: same sentinel handling via wrapper function.
- 6 test files updated: all 'forces temperature X' assertions replaced
  with 'temperature not in kwargs' assertions.

Net: -76 lines (171 added, 247 removed).

570f8bab8f fix(compression): exclude completion tokens from compression trigger (#12026)
Cherry-picked from PR #12481 by @Sanjays2402.

Reasoning models (GLM-5.1, QwQ, DeepSeek R1) inflate completion_tokens
with internal thinking tokens. The compression trigger summed
prompt_tokens + completion_tokens, causing premature compression at ~42%
actual context usage instead of the configured 50% threshold.

Now uses only prompt_tokens — completion tokens don't consume context
window space for the next API call.

- 3 new regression tests
- Added AUTHOR_MAP entry for @Sanjays2402

feat(api-server): inline image inputs on /v1/chat/completions and /v1/responses (#12969)
OpenAI-compatible clients (Open WebUI, LobeChat, etc.) can now send vision
requests to the API server. Both endpoints accept the canonical OpenAI
multimodal shape:

  Chat Completions: {type: text|image_url, image_url: {url, detail?}}
  Responses:        {type: input_text|input_image, image_url: <str>, detail?}

The server validates and converts both into a single internal shape that the
existing agent pipeline already handles (Anthropic adapter converts,
OpenAI-wire providers pass through). Remote http(s) URLs and data:image/*
URLs are supported.

Uploaded files (file, input_file, file_id) and non-image data: URLs are
rejected with 400 unsupported_content_type.

Changes:

- gateway/platforms/api_server.py
  - _normalize_multimodal_content(): validates + normalizes both Chat and
    Responses content shapes. Returns a plain string for text-only content
    (preserves prompt-cache behavior on existing callers) or a canonical
    [{type:text|image_url,...}] list when images are present.
  - _content_has_visible_payload(): replaces the bare truthy check so a
    user turn with only an image no longer rejects as 'No user message'.
  - _handle_chat_completions and _handle_responses both call the new helper
    for user/assistant content; system messages continue to flatten to text.
  - Codex conversation_history, input[], and inline history paths all share
    the same validator. No duplicated normalizers.

- run_agent.py
  - _summarize_user_message_for_log(): produces a short string summary
    ('[1 image] describe this') from list content for logging, spinner
    previews, and trajectory writes. Fixes AttributeError when list
    user_message hit user_message[:80] + '...' / .replace().
  - _chat_content_to_responses_parts(): module-level helper that converts
    chat-style multimodal content to Responses 'input_text'/'input_image'
    parts. Used in _chat_messages_to_responses_input for Codex routing.
  - _preflight_codex_input_items() now validates and passes through list
    content parts for user/assistant messages instead of stringifying.

- tests/gateway/test_api_server_multimodal.py (new, 38 tests)
  - Unit coverage for _normalize_multimodal_content, including both part
    formats, data URL gating, and all reject paths.
  - Real aiohttp HTTP integration on /v1/chat/completions and /v1/responses
    verifying multimodal payloads reach _run_agent intact.
  - 400 coverage for file / input_file / non-image data URL.

- tests/run_agent/test_run_agent_multimodal_prologue.py (new)
  - Regression coverage for the prologue no-crash contract.
  - _chat_content_to_responses_parts round-trip coverage.

- website/docs/user-guide/features/api-server.md
  - Inline image examples for both endpoints.
  - Updated Limitations: files still unsupported, images now supported.

Validated live against openrouter/anthropic/claude-opus-4.6:
  POST /v1/chat/completions  → 200, vision-accurate description
  POST /v1/responses         → 200, same image, clean output_text
  POST /v1/chat/completions [file] → 400 unsupported_content_type
  POST /v1/responses [input_file]  → 400 unsupported_content_type
  POST /v1/responses [non-image data URL] → 400 unsupported_content_type

fix(compression): enforce 64k floor on aux model + auto-correct threshold (#12898)
Context compression silently failed when the auxiliary compression model's
context window was smaller than the main model's compression threshold
(e.g. GLM-4.5-air at 131k paired with a 150k threshold).  The feasibility
check warned but the session kept running and compression attempts errored
out mid-conversation.

Two changes in _check_compression_model_feasibility():

1. Hard floor: if detected aux context < MINIMUM_CONTEXT_LENGTH (64k),
   raise ValueError so the session refuses to start.  Mirrors the existing
   main-model rejection at AIAgent.__init__ line 1600.  A compression model
   below 64k cannot summarise a full threshold-sized window.

2. Auto-correct: when aux context is >= 64k but below the computed
   threshold, lower the live compressor's threshold_tokens to aux_context
   (and update threshold_percent to match so later update_model() calls
   stay in sync).  Warning reworded to say what was done and how to
   persist the fix in config.yaml.

Only ValueError re-raises; other exceptions in the check remain swallowed
as non-fatal.

fix(anthropic): complete third-party Anthropic-compatible provider support (#12846)
Third-party gateways that speak the native Anthropic protocol (MiniMax,
Zhipu GLM, Alibaba DashScope, Kimi, LiteLLM proxies) now work end-to-end
with the same feature set as direct api.anthropic.com callers.  Synthesizes
eight stale community PRs into one consolidated change.

Five fixes:

- URL detection: consolidate three inline `endswith("/anthropic")`
  checks in runtime_provider.py into the shared _detect_api_mode_for_url
  helper.  Third-party /anthropic endpoints now auto-resolve to
  api_mode=anthropic_messages via one code path instead of three.

- OAuth leak-guard: all five sites that assign `_is_anthropic_oauth`
  (__init__, switch_model, _try_refresh_anthropic_client_credentials,
  _swap_credential, _try_activate_fallback) now gate on
  `provider == "anthropic"` so a stale ANTHROPIC_TOKEN never trips
  Claude-Code identity injection on third-party endpoints.  Previously
  only 2 of 5 sites were guarded.

- Prompt caching: new method `_anthropic_prompt_cache_policy()` returns
  `(should_cache, use_native_layout)` per endpoint.  Replaces three
  inline conditions and the `native_anthropic=(api_mode=='anthropic_messages')`
  call-site flag.  Native Anthropic and third-party Anthropic gateways
  both get the native cache_control layout; OpenRouter gets envelope
  layout.  Layout is persisted in `_primary_runtime` so fallback
  restoration preserves the per-endpoint choice.

- Auxiliary client: `_try_custom_endpoint` honors
  `api_mode=anthropic_messages` and builds `AnthropicAuxiliaryClient`
  instead of silently downgrading to an OpenAI-wire client.  Degrades
  gracefully to OpenAI-wire when the anthropic SDK isn't installed.

- Config hygiene: `_update_config_for_provider` (hermes_cli/auth.py)
  clears stale `api_key`/`api_mode` when switching to a built-in
  provider, so a previous MiniMax custom endpoint's credentials can't
  leak into a later OpenRouter session.

- Truncation continuation: length-continuation and tool-call-truncation
  retry now cover `anthropic_messages` in addition to `chat_completions`
  and `bedrock_converse`.  Reuses the existing `_build_assistant_message`
  path via `normalize_anthropic_response()` so the interim message
  shape is byte-identical to the non-truncated path.

Tests: 6 new files, 42 test cases.  Targeted run + tests/run_agent,
tests/agent, tests/hermes_cli all pass (4554 passed).

c9b833feb3 fix(ci): unblock test suite + cut ~2s of dead Z.AI probes from every AIAgent
CI on main had 7 failing tests. Five were stale test fixtures; one (agent
cache spillover timeout) was covering up a real perf regression in
AIAgent construction.

The perf bug: every AIAgent.__init__ calls _check_compression_model_feasibility
→ resolve_provider_client('auto') → _resolve_api_key_provider which
iterates PROVIDER_REGISTRY.  When it hits 'zai', it unconditionally calls
resolve_api_key_provider_credentials → _resolve_zai_base_url → probes 8
Z.AI endpoints with an empty Bearer token (all 401s), ~2s of pure latency
per agent, even when the user has never touched Z.AI.  Landed in
9e844160 (PR for credential-pool Z.AI auto-detect) — the short-circuit
when api_key is empty was missing.  _resolve_kimi_base_url had the same
shape; fixed too.

Test fixes:
- tests/gateway/test_voice_command.py: _make_adapter helpers were missing
  self._voice_locks (added in PR #12644, 7 call sites — all updated).
- tests/test_toolsets.py: test_hermes_platforms_share_core_tools asserted
  equality, but hermes-discord has discord_server (DISCORD_BOT_TOKEN-gated,
  discord-only by design).  Switched to subset check.
- tests/run_agent/test_streaming.py: test_tool_name_not_duplicated_when_resent_per_chunk
  missing api_key/base_url — classic pitfall (PR #11619 fixed 16 of
  these; this one slipped through on a later commit).
- tests/tools/test_discord_tool.py: TestConfigAllowlist caplog assertions
  fail in parallel runs because AIAgent(quiet_mode=True) globally sets
  logging.getLogger('tools').setLevel(ERROR) and xdist workers are
  persistent.  Autouse fixture resets the 'tools' and
  'tools.discord_tool' levels per test.

Validation:
  tests/cron + voice + agent_cache + streaming + toolsets + command_guards
  + discord_tool: 550/550 pass
  tests/hermes_cli + tests/gateway: 5713/5713 pass
  AIAgent construction without Z.AI creds: 2.2s → 0.24s (9x)

fix(tests): unstick CI — sweep stale tests from recent merges (#12670)
One source fix (web_server category merge) + five test updates that
didn't travel with their feature PRs. All 13 failures on the 04-19
CI run on main are now accounted for (5 already self-healed on main;
8 fixed here).

Changes
- web_server.py: add code_execution → agent to _CATEGORY_MERGE (new
  singleton section from #11971 broke no-single-field-category invariant).
- test_browser_camofox_state: bump hardcoded _config_version 18 → 19
  (also from #11971).
- test_registry: add browser_cdp_tool (#12369) and discord_tool (#4753)
  to the expected built-in tool set.
- test_run_agent::test_tool_call_accumulation: rewrite fragment chunks
  — #0f778f77 switched streaming name-accumulation from += to = to
  fix MiniMax/NIM duplication; the test still encoded the old
  fragment-per-chunk premise.
- test_concurrent_interrupt::_Stub: no-op
  _apply_pending_steer_to_tool_results — #12116 added this call after
  concurrent tool batches; the hand-rolled stub was missing it.
- test_codex_cli_model_picker: drop the two obsolete tests that
  asserted auto-import from ~/.codex/auth.json into the Hermes auth
  store. #12360 explicitly removed that behavior (refresh-token reuse
  races with Codex CLI / VS Code); adoption is now explicit via
  `hermes auth openai-codex`. Remaining 3 tests in the file (normal
  path, Claude Code fallback, negative case) still cover the picker.

Validation
- scripts/run_tests.sh across all 6 affected files + surrounding tests
  (54 tests total) all green locally.

f1fe29d1c3 feat(providers): extend request_timeout_seconds to all client paths
Follow-up on top of mvanhorn's cherry-picked commit. Original PR only
wired request_timeout_seconds into the explicit-creds OpenAI branch at
run_agent.py init; router-based implicit auth, native Anthropic, and the
fallback chain were still hardcoded to SDK defaults.

- agent/anthropic_adapter.py: build_anthropic_client() accepts an optional
  timeout kwarg (default 900s preserved when unset/invalid).
- run_agent.py: resolve per-provider/per-model timeout once at init; apply
  to Anthropic native init + post-refresh rebuild + stale/interrupt
  rebuilds + switch_model + _restore_primary_runtime + the OpenAI
  implicit-auth path + _try_activate_fallback (with immediate client
  rebuild so the first fallback request carries the configured timeout).
- tests: cover anthropic adapter kwarg honoring; widen mock signatures
  to accept the new timeout kwarg.
- docs/example: clarify that the knob now applies to every transport,
  the fallback chain, and rebuilds after credential rotation.

045b28733e fix(compression): resolve missing config attribute in feasibility check
Commit 4a9c3565 added a reference to `self.config` in
`_check_compression_model_feasibility()` to pass the user-configured
`auxiliary.compression.context_length` to `get_model_context_length()`.
However, `AIAgent` never stores the loaded config dict as an instance
attribute — the config is loaded into a local variable `_agent_cfg` in
`__init__()` and discarded after init.

This causes an `AttributeError: 'AIAgent' object has no attribute
'config'` on every session start when compression is enabled, caught by
the try/except and logged as a non-fatal DEBUG message.

Fix: store the loaded config as `self._config` in `__init__()` and
update the reference in the feasibility check to use `self._config`.

ec48ec5530 fix(agent): strip <think> blocks from stored assistant content
Inline reasoning tags in an assistant message's content field leak to every downstream consumer: messaging platforms (#8878, #9568), API replay of prior turns, session transcript, CLI recap, generated session titles, and context compression.  _extract_reasoning() already captures the reasoning text into msg['reasoning'] separately, so the raw tags in content are redundant.

Stripping once at the storage boundary in _build_assistant_message() cleans the content for every downstream path in one place — no per-platform or per-path stripper needed.  Measured impact on a real MiniMax M2.7-highspeed session (per @luoyejiaoe-source, #9306): 55% of assistant messages started with <think> blocks, 51/100 session titles were polluted, 16% content-size reduction.

3 new regression tests in TestBuildAssistantMessage: closed-pair strip with reasoning capture, no-think-tag passthrough, and unterminated-block strip.

Resolves #8878 and #9568.

9489d1577d fix(agent): strip unterminated <think> blocks from visible content
Providers served via NIM (MiniMax M2.7, some Moonshot/DeepSeek proxies) sometimes drop the closing </think> tag, leaving raw reasoning in the assistant's content field.  _strip_think_blocks()'s closed-pair regex is non-greedy so it only matches complete blocks — any orphan <think>...EOF survived the stripper and leaked to users (#8878, #9568, #10408).

Adds an unterminated-tag pass that fires when an open reasoning tag sits at a block boundary (start of text or after a newline) with no matching close.  Everything from that tag to end of string is stripped.  The block-boundary check mirrors gateway/stream_consumer.py's filter so models that mention <think> in prose are not over-stripped.

Also makes the closed-pair regexes consistently case-insensitive so <THINK>...</THINK> and <Thinking>...</Thinking> are handled uniformly — previously the mixed-case open tag would bypass the closed-pair pass and be caught by the unterminated-tag pass, taking trailing visible content with it.

6 new regression tests in TestStripThinkBlocks covering: unterminated <think>, unterminated <thought>, multi-line unterminated, line-start orphan with preserved prefix, prose-mention non-regression, mixed-case closed pairs.

The implementation is inspired by @luinbytes's PR #10408 report of the NIM/MiniMax symptom.  This commit does not include the 💭/🧠 emoji regexes from that PR — those glyphs are Hermes CLI display decorations, not model content markers.
