c52353cf8a feat: context pressure warnings for CLI and gateway (#2159)
* feat: context pressure warnings for CLI and gateway

User-facing notifications as context approaches the compaction threshold.
Warnings fire at 60% and 85% of the way to compaction — relative to
the configured compression threshold, not the raw context window.

CLI: Formatted line with a progress bar showing distance to compaction.
Cyan at 60% (approaching), bold yellow at 85% (imminent).

  ◐ context ▰▰▰▰▰▰▰▰▰▰▰▰▱▱▱▱▱▱▱▱ 60% to compaction  100k threshold (50%) · approaching compaction
  ⚠ context ▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▰▱▱▱ 85% to compaction  100k threshold (50%) · compaction imminent

Gateway: Plain-text notification sent to the user's chat via the new
status_callback mechanism (asyncio.run_coroutine_threadsafe bridge,
same pattern as step_callback).

Does NOT inject into the message stream. The LLM never sees these
warnings. Flags reset after each compaction cycle.

Files changed:
- agent/display.py — format_context_pressure(), format_context_pressure_gateway()
- run_agent.py — status_callback param, _context_50/70_warned flags,
  _emit_context_pressure(), flag reset in _compress_context()
- gateway/run.py — _status_callback_sync bridge, wired to AIAgent
- tests/test_context_pressure.py — 23 tests

* Merge remote-tracking branch 'origin/main' into hermes/hermes-7ea545bf

88643a1ba9 feat: overhaul context length detection with models.dev and provider-aware resolution (#2158)
Replace the fragile hardcoded context length system with a multi-source
resolution chain that correctly identifies context windows per provider.

Key changes:

- New agent/models_dev.py: Fetches and caches the models.dev registry
  (3800+ models across 100+ providers with per-provider context windows).
  In-memory cache (1hr TTL) + disk cache for cold starts.

- Rewritten get_model_context_length() resolution chain:
  0. Config override (model.context_length)
  1. Custom providers per-model context_length
  2. Persistent disk cache
  3. Endpoint /models (local servers)
  4. Anthropic /v1/models API (max_input_tokens, API-key only)
  5. OpenRouter live API (existing, unchanged)
  6. Nous suffix-match via OpenRouter (dot/dash normalization)
  7. models.dev registry lookup (provider-aware)
  8. Thin hardcoded defaults (broad family patterns)
  9. 128K fallback (was 2M)

- Provider-aware context: same model now correctly resolves to different
  context windows per provider (e.g. claude-opus-4.6: 1M on Anthropic,
  128K on GitHub Copilot). Provider name flows through ContextCompressor.

- DEFAULT_CONTEXT_LENGTHS shrunk from 80+ entries to ~16 broad patterns.
  models.dev replaces the per-model hardcoding.

- CONTEXT_PROBE_TIERS changed from [2M, 1M, 512K, 200K, 128K, 64K, 32K]
  to [128K, 64K, 32K, 16K, 8K]. Unknown models no longer start at 2M.

- hermes model: prompts for context_length when configuring custom
  endpoints. Supports shorthand (32k, 128K). Saved to custom_providers
  per-model config.

- custom_providers schema extended with optional models dict for
  per-model context_length (backward compatible).

- Nous Portal: suffix-matches bare IDs (claude-opus-4-6) against
  OpenRouter's prefixed IDs (anthropic/claude-opus-4.6) with dot/dash
  normalization. Handles all 15 current Nous models.

- Anthropic direct: queries /v1/models for max_input_tokens. Only works
  with regular API keys (sk-ant-api*), not OAuth tokens. Falls through
  to models.dev for OAuth users.

Tests: 5574 passed (18 new tests for models_dev + updated probe tiers)
Docs: Updated configuration.md context length section, AGENTS.md

b313751acf fix(display): show spinners and tool progress during streaming mode
When streaming was enabled, two visual feedback mechanisms were
completely suppressed:

1. The thinking spinner (TUI toolbar) was skipped because the entire
   spinner block was gated on 'not self._has_stream_consumers()'.
   Now the thinking_callback fires in streaming mode too — the
   raw KawaiiSpinner is still skipped (would conflict with streamed
   tokens) but the TUI toolbar widget works fine alongside streaming.

2. Tool progress lines (the ┊ feed) were invisible because _vprint
   was blanket-suppressed when stream consumers existed. But during
   tool execution, no tokens are actively streaming, so printing is
   safe. Added an _executing_tools flag that _vprint respects to
   allow output during tool execution even with stream consumers
   registered.

b1d05dfe8b fix(openai): route api.openai.com to Responses API for GPT-5.x
Based on PR #1859 by @magi-morph (too stale to cherry-pick, reimplemented).

GPT-5.x models reject tool calls + reasoning_effort on
/v1/chat/completions with a 400 error directing to /v1/responses.
This auto-detects api.openai.com in the base URL and switches to
codex_responses mode in three places:

- AIAgent.__init__: upgrades chat_completions → codex_responses
- _try_activate_fallback(): same routing for fallback model
- runtime_provider.py: _detect_api_mode_for_url() for both custom
  provider and openrouter runtime resolution paths

Also extracts _is_direct_openai_url() helper to replace the inline
check in _max_tokens_param().

746abf5e28 fix: use reasoning content as response when model only produces think blocks
Local models (especially Qwen 3.5) sometimes wrap their entire response
inside <think> tags, leaving actual content empty. Previously this caused
3 retries and then an error, wasting tokens and failing the request.

Now when retries are exhausted and reasoning_text contains the response,
it is used as final_response instead of returning an error. The user
sees the actual answer instead of "Model generated only think blocks."

e84d952dc0 fix(codex): handle reasoning-only responses and replay path (#2070)
* fix(codex): treat reasoning-only responses as incomplete, not stop

When a Codex Responses API response contains only reasoning items
(encrypted thinking state) with no message text or tool calls, the
_normalize_codex_response method was setting finish_reason='stop'.
This sent the response into the empty-content retry loop, which
burned 3 retries and then failed — exactly the pattern Nester
reported in Discord.

Two fixes:
1. _normalize_codex_response: reasoning-only responses (reasoning_items_raw
   non-empty but no final_text) now get finish_reason='incomplete', routing
   them to the Codex continuation path instead of the retry loop.
2. Incomplete handling: also checks for codex_reasoning_items when deciding
   whether to preserve an interim message, so encrypted reasoning state is
   not silently dropped when there is no visible reasoning text.

Adds 4 regression tests covering:
- Unit: reasoning-only → incomplete, reasoning+content → stop
- E2E: reasoning-only → continuation → final answer succeeds
- E2E: encrypted reasoning items preserved in interim messages

* fix(codex): ensure reasoning items have required following item in API input

Follow-up to the reasoning-only response fix. Three additional issues
found by tracing the full replay path:

1. _chat_messages_to_responses_input: when a reasoning-only interim
   message was converted to Responses API input, the reasoning items
   were emitted as the last items with no following item. The Responses
   API requires a following item after each reasoning item (otherwise:
   'missing_following_item' error, as seen in OpenHands #11406). Now
   emits an empty assistant message as the required following item when
   content is empty but reasoning items were added.

2. Duplicate detection: two consecutive reasoning-only incomplete
   messages with identical empty content/reasoning but different
   encrypted codex_reasoning_items were incorrectly treated as
   duplicates, silently dropping the second response's reasoning state.
   Now includes codex_reasoning_items in the duplicate comparison.

3. Added tests for both the API input conversion path and the duplicate
   detection edge case.

Research context: verified against OpenCode (uses Vercel AI SDK, no
retry loop so avoids the issue), Clawdbot (drops orphaned reasoning
blocks entirely), and OpenHands (hit the missing_following_item error).
Our approach preserves reasoning continuity while satisfying the API
constraint.

d76fa7fc37 fix: detect context length for custom model endpoints via fuzzy matching + config override (#2051)
* fix: detect context length for custom model endpoints via fuzzy matching + config override

Custom model endpoints (non-OpenRouter, non-known-provider) were silently
falling back to 2M tokens when the model name didn't exactly match what the
endpoint's /v1/models reported. This happened because:

1. Endpoint metadata lookup used exact match only — model name mismatches
   (e.g. 'qwen3.5:9b' vs 'Qwen3.5-9B-Q4_K_M.gguf') caused a miss
2. Single-model servers (common for local inference) required exact name
   match even though only one model was loaded
3. No user escape hatch to manually set context length

Changes:
- Add fuzzy matching for endpoint model metadata: single-model servers
  use the only available model regardless of name; multi-model servers
  try substring matching in both directions
- Add model.context_length config override (highest priority) so users
  can explicitly set their model's context length in config.yaml
- Log an informative message when falling back to 2M probe, telling
  users about the config override option
- Thread config_context_length through ContextCompressor and AIAgent init

Tests: 6 new tests covering fuzzy match, single-model fallback, config
override (including zero/None edge cases).

* fix: auto-detect local model name and context length for local servers

Cherry-picked from PR #2043 by sudoingX.

- Auto-detect model name from local server's /v1/models when only one
  model is loaded (no manual model name config needed)
- Add n_ctx_train and n_ctx to context length detection keys for llama.cpp
- Query llama.cpp /props endpoint for actual allocated context (not just
  training context from GGUF metadata)
- Strip .gguf suffix from display in banner and status bar
- _auto_detect_local_model() in runtime_provider.py for CLI init

a7cc1cf309 fix: support Anthropic-compatible endpoints for third-party providers (#1997)
Three bugs prevented providers like MiniMax from using their
Anthropic-compatible endpoints (e.g. api.minimax.io/anthropic):

1. _VALID_API_MODES was missing 'anthropic_messages', so explicit
   api_mode config was silently rejected and defaulted to
   chat_completions.

2. API-key provider resolution hardcoded api_mode to 'chat_completions'
   without checking model config or detecting Anthropic-compatible URLs.

3. run_agent.py auto-detection only recognized api.anthropic.com, not
   third-party endpoints using the /anthropic URL convention.

Fixes:
- Add 'anthropic_messages' to _VALID_API_MODES
- API-key providers now check model config api_mode and auto-detect
  URLs ending in /anthropic
- run_agent.py and fallback logic detect /anthropic URL convention
- 5 new tests covering all scenarios

Users can now either:
- Set MINIMAX_BASE_URL=https://api.minimax.io/anthropic (auto-detected)
- Set api_mode: anthropic_messages in model config (explicit)
- Use custom_providers with api_mode: anthropic_messages

e4a3ffa9c1 feat: use SOUL.md as primary agent identity instead of hardcoded default (#1922)
SOUL.md now loads in slot #1 of the system prompt, replacing the
hardcoded DEFAULT_AGENT_IDENTITY. This lets users fully customize
the agent's identity and personality by editing ~/.hermes/SOUL.md
without it conflicting with the built-in identity text.

When SOUL.md is loaded as identity, it's excluded from the context
files section to avoid appearing twice. When SOUL.md is missing,
empty, unreadable, or skip_context_files is set, the hardcoded
DEFAULT_AGENT_IDENTITY is used as a fallback.

The default SOUL.md (seeded on first run) already contains the full
Hermes personality, so existing installs are unaffected.

85993fbb5a feat: pre-call sanitization and post-call tool guardrails (#1732)
Salvage of PR #1321 by @alireza78a (cherry-picked concept, reimplemented
against current main).

Phase 1 — Pre-call message sanitization:
  _sanitize_api_messages() now runs unconditionally before every LLM call.
  Previously gated on context_compressor being present, so sessions loaded
  from disk or running without compression could accumulate dangling
  tool_call/tool_result pairs causing API errors.

Phase 2a — Delegate task cap:
  _cap_delegate_task_calls() truncates excess delegate_task calls per turn
  to MAX_CONCURRENT_CHILDREN. The existing cap in delegate_tool.py only
  limits the task array within a single call; this catches multiple
  separate delegate_task tool_calls in one turn.

Phase 2b — Tool call deduplication:
  _deduplicate_tool_calls() drops duplicate (tool_name, arguments) pairs
  within a single turn when models stutter.

All three are static methods on AIAgent, independently testable.

2. HTTP 429 / rate-limit keyword detection — fallback before backoff

Both guarded by _fallback_activated for one-shot semantics.

cd6dc4ef7e fix(core): message role violations in JSON recovery and error handler
Two edge cases could inject messages that violate role alternation:

1. Invalid JSON recovery (line ~5985): After 3 retries of invalid JSON
   tool args, a user-role recovery message was injected. But the
   assistant's tool_calls were never appended, so the sequence could
   become user → user. Fix: append the assistant message with its
   tool_calls, then respond with proper tool-role error results.

2. System error handler (line ~6238): Always injected a user-role
   error message, which creates consecutive user messages if the last
   message was already user. Fix: dynamically choose the role based on
   the last message to maintain alternation.

1d5a39e002 fix: thread safety for concurrent subagent delegation (#1672)
* fix: thread safety for concurrent subagent delegation

Four thread-safety fixes that prevent crashes and data races when
running multiple subagents concurrently via delegate_task:

1. Remove redirect_stdout/stderr from delegate_tool — mutating global
   sys.stdout races with the spinner thread when multiple children start
   concurrently, causing segfaults. Children already run with
   quiet_mode=True so the redirect was redundant.

2. Split _run_single_child into _build_child_agent (main thread) +
   _run_single_child (worker thread). AIAgent construction creates
   httpx/SSL clients which are not thread-safe to initialize
   concurrently.

3. Add threading.Lock to SessionDB — subagents share the parent's
   SessionDB and call create_session/append_message from worker threads
   with no synchronization.

4. Add _active_children_lock to AIAgent — interrupt() iterates
   _active_children while worker threads append/remove children.

5. Add _client_cache_lock to auxiliary_client — multiple subagent
   threads may resolve clients concurrently via call_llm().

     honcho:
       base_url: "http://192.168.x.x:8000"

   When set, this overrides the Honcho SDK's environment mapping
   (production/local), enabling LAN/VPN Honcho deployments without
   requiring the server to live on localhost. Uses config.yaml instead
   of env var (HONCHO_URL) per project convention.

2. Quick command alias type: adds a new 'alias' quick command type
   that rewrites to another slash command before normal dispatch:

     quick_commands:
       sc:
         type: alias
         target: /context

   Supports both CLI and gateway. Arguments are forwarded to the
   target command.

a3ac142c83 fix(core): guard print() calls in run_conversation() against OSError
In headless environments (systemd, Docker, nohup) stdout can become
unavailable mid-session. Raw print() raises OSError which crashes
cron jobs — agent finishes work but delivery never happens because
the error handler's own print() also raises OSError.

Fix:
- Add _safe_print() static method that wraps print() with try/except
  OSError — silently drops output when stdout is broken
- Make _vprint() use _safe_print() — protects all calls through the
  verbose print path
- Convert raw print() calls in run_conversation() hot path to use
  _safe_print(): starting conversation, interrupt, budget exhausted,
  preflight compression, context cache, conversation completed
- Error handler print (the cascading crash point) gets explicit
  try/except with logger.error() fallback so diagnostics aren't lost

f2414bfd45 feat: allow custom endpoints to use responses API via api_mode override (#1651)
Add HERMES_API_MODE env var and model.api_mode config field to let
custom OpenAI-compatible endpoints opt into codex_responses mode
without requiring the OpenAI Codex OAuth provider path.

- _get_configured_api_mode() reads HERMES_API_MODE env (precedence)
  then model.api_mode from config.yaml; validates against whitelist
- Applied in both _resolve_openrouter_runtime() and
  _resolve_named_custom_runtime() (original PR only covered openrouter)
- Fix _dump_api_request_debug() to show /responses URL when in
  codex_responses mode instead of always showing /chat/completions
- Tests for config override, env override, invalid values, named
  custom providers, and debug dump URL for both API modes

96dac22194 fix: prevent infinite 400 loop on context overflow + block prompt injection via cache files (#1630, #1558)
* fix: prevent infinite 400 failure loop on context overflow (#1630)

When a gateway session exceeds the model's context window, Anthropic may
return a generic 400 invalid_request_error with just 'Error' as the
message.  This bypassed the phrase-based context-length detection,
causing the agent to treat it as a non-retryable client error.  Worse,
the failed user message was still persisted to the transcript, making
the session even larger on each attempt — creating an infinite loop.

Three-layer fix:

1. run_agent.py — Fallback heuristic: when a 400 error has a very short
   generic message AND the session is large (>40% of context or >80
   messages), treat it as a probable context overflow and trigger
   compression instead of aborting.

2. run_agent.py + gateway/run.py — Don't persist failed messages:
   when the agent returns failed=True before generating any response,
   skip writing the user's message to the transcript/DB. This prevents
   the session from growing on each failure.

3. gateway/run.py — Smarter error messages: detect context-overflow
   failures and suggest /compact or /reset specifically, instead of a
   generic 'try again' that will fail identically.

* fix(skills): detect prompt injection patterns and block cache file reads

Adds two security layers to prevent prompt injection via skills hub
cache files (#1558):

1. read_file: blocks direct reads of ~/.hermes/skills/.hub/ directory
   (index-cache, catalog files). The 3.5MB clawhub_catalog_v1.json
   was the original injection vector — untrusted skill descriptions
   in the catalog contained adversarial text that the model executed.

2. skill_view: warns when skills are loaded from outside the trusted
   ~/.hermes/skills/ directory, and detects common injection patterns
   in skill content ("ignore previous instructions", "<system>", etc.).

8d0a96a8bf fix: context counter shows cached token count in status bar
Anthropic prompt caching splits input into cache_read_input_tokens,
cache_creation_input_tokens, and non-cached input_tokens. The context
counter only read input_tokens (non-cached portion), showing ~3 tokens
instead of the real ~18K total. Now includes cached portions for
Anthropic native provider only — other providers (OpenAI, OpenRouter,
Codex) already include cached tokens in their prompt_tokens field.

Before: 3/200K | 0%
After: 17.7K/200K | 9%

2158c44efd fix: Anthropic OAuth compatibility — Claude Code identity fingerprinting (#1597)
Anthropic routes OAuth/subscription requests based on Claude Code's
identity markers. Without them, requests get intermittent 500 errors
(~25% failure rate observed). This matches what pi-ai (clawdbot) and
OpenCode both implement for OAuth compatibility.

Changes (OAuth tokens only — API key users unaffected):

1. Headers: user-agent 'claude-cli/2.1.2 (external, cli)' + x-app 'cli'
2. System prompt: prepend 'You are Claude Code, Anthropic's official CLI'
3. System prompt sanitization: replace Hermes/Nous references
4. Tool names: prefix with 'mcp_' (Claude Code convention for non-native tools)
5. Tool name stripping: remove 'mcp_' prefix from response tool calls

Before: 9/12 OK, 1 hard fail, 4 needed retries (~25% error rate)
After: 16/16 OK, 0 failures, 0 retries (0% error rate)

- 429 rate limit and 529 overloaded were incorrectly treated as

  exponential backoff retry. Users hitting Anthropic rate limits got
  silent failures or no response at all.
- Generic "Sorry, I encountered an unexpected error" now includes
  error type, details, and status-specific hints (auth, rate limit,
  overloaded).
- Failed agent with final_response=None now surfaces the actual
  error message instead of returning an empty response.

1ecfe68675 feat: improve memory prioritization + aggressive skill updates (inspired by OpenAI Codex)
* feat: improve memory prioritization — user preferences over procedural knowledge

Inspired by OpenAI Codex's memory prompt improvements (openai/codex#14493)
which focus memory writes on user preferences and recurring patterns
rather than procedural task details.

Key insight: 'Optimize for reducing future user steering — the most
valuable memory prevents the user from having to repeat themselves.'

Changes:
- MEMORY_GUIDANCE (prompt_builder.py): added prioritization hierarchy
  and the core principle about reducing user steering
- MEMORY_SCHEMA (memory_tool.py): reordered WHEN TO SAVE list to put
  corrections first, added explicit PRIORITY guidance
- Memory nudge (run_agent.py): now asks specifically about preferences,
  corrections, and workflow patterns instead of generic 'anything'
- Memory flush (run_agent.py): now instructs to prioritize user
  preferences and corrections over task-specific details

* feat: more aggressive skill creation and update prompting

Press harder on skill updates — the agent should proactively patch
skills when it encounters issues during use, not wait to be asked.

Changes:
- SKILLS_GUIDANCE: 'consider saving' → 'save'; added explicit instruction
  to patch skills immediately when found outdated/wrong
- Skills header: added instruction to update loaded skills before finishing
  if they had missing steps or wrong commands
- Skill nudge: more assertive ('save the approach' not 'consider saving'),
  now also prompts for updating existing skills used in the task
- Skill nudge interval: lowered default from 15 to 10 iterations
- skill_manage schema: added 'patch it immediately' to update triggers

8e07f9ca56 fix: audit fixes — 5 bugs found and resolved
Thorough code review found 5 issues across run_agent.py, cli.py, and gateway/:

1. CRITICAL — Gateway stream consumer task never started: stream_consumer_holder
   was checked BEFORE run_sync populated it. Fixed with async polling pattern
   (same as track_agent).

2. MEDIUM-HIGH — Streaming fallback after partial delivery caused double-response:
   if streaming failed after some tokens were delivered, the fallback would
   re-deliver the full response. Now tracks deltas_were_sent and only falls
   back when no tokens reached consumers yet.

3. MEDIUM — Codex mode lost on_first_delta spinner callback: _run_codex_stream
   now accepts on_first_delta parameter, fires it on first text delta. Passed
   through from _interruptible_streaming_api_call via _codex_on_first_delta
   instance attribute.

4. MEDIUM — CLI close-tag after-text bypassed tag filtering: text after a
   reasoning close tag was sent directly to _emit_stream_text, skipping
   open-tag detection. Now routes through _stream_delta for full filtering.

5. LOW — Removed 140 lines of dead code: old _streaming_api_call method
   (superseded by _interruptible_streaming_api_call). Updated 13 tests in
   test_run_agent.py and test_openai_client_lifecycle.py to use the new
   method name and signature.

4573 tests passing.

99369b926c fix: always fall back to non-streaming on ANY streaming error
Previously the fallback only triggered on specific error keywords like
'streaming is not supported'. Many third-party providers have partial
or broken streaming — rejecting stream=True, crashing on stream_options,
dropping connections mid-stream, returning malformed chunks, etc.

Now: any exception during the streaming API call triggers an automatic
fallback to the standard non-streaming request path. The error is logged
at INFO level for diagnostics but never surfaces to the user. If the
fallback also fails, THAT error propagates normally.

This ensures streaming is additive — it improves UX when it works but
never breaks providers that don't support it.

Tests: 2 new (any-error fallback, double-failure propagation), 15 total.
