Haiku models don't support extended thinking at all. Without this
guard, claude-haiku-4-5-20251001 would receive type=enabled +
budget_tokens and return a 400 error.
Incorporates the fix from PR #1127 (by frizynn) on top of #1128's
adaptive thinking refactor.
Verified live with Claude Code OAuth:
claude-opus-4-6 → adaptive thinking ✓
claude-haiku-4-5 → no thinking params ✓
claude-sonnet-4 → enabled thinking ✓
For Claude 4.6 models (Opus and Sonnet), the Anthropic API rejects
budget_tokens when thinking.type is 'adaptive'. This was causing a
400 error: 'thinking.adaptive.budget_tokens: Extra inputs are not
permitted'.
Changes:
- Send thinking: {type: 'adaptive'} without budget_tokens for 4.6
- Move effort control to output_config: {effort: ...} per Anthropic docs
- Map Hermes effort levels to Anthropic effort levels (xhigh->max, etc.)
- Narrow adaptive detection to 4.6 models only (4.5 still uses manual)
- Add tests for adaptive thinking on 4.6 and manual thinking on pre-4.6
Fixes#1126
When Anthropic returns 401 and credential refresh doesn't help,
now prints actionable troubleshooting info:
- Which auth method was used (Bearer vs x-api-key)
- Token prefix for debugging
- Common fixes (stale ANTHROPIC_API_KEY, verify key, refresh login)
- How to clear stale keys
Clean fix — removes dead code that crashed with NameError on is_coding_plan. The generic _setup_provider_model_selection() already handles all affected providers.
Remove 50 lines of unreachable duplicate model selection logic in
setup_model_provider() for zai/kimi-coding/minimax/minimax-cn providers.
The code referenced undefined `is_coding_plan` variable, crashing setup.
_setup_provider_model_selection() already handles these providers correctly
via _DEFAULT_PROVIDER_MODELS dict.
Fallback paths in send_image_file, send_video, and send_document called
super() without metadata, causing replies to appear outside the thread
when file upload fails. Use self.send() with metadata instead to preserve
thread_ts context.
- Pass self.max_tokens to build_anthropic_kwargs instead of hardcoded None
- Add anthropic case to _try_activate_fallback (was only handling openai-codex)
- Remove 'anthropic in base_url' filter that blocked custom proxy URLs
- Increase MAX_MESSAGE_LENGTH from 3,900 to 39,000 (Slack API allows 40k)
- Implement real typing indicator using assistant.threads.setStatus API
- Shows 'BotName is thinking...' next to the bot name in threads
- Auto-clears when the bot sends a reply
- Requires assistant:write or chat:write scope
- Falls back silently if scope unavailable (reactions still work)
- 4 new tests for typing indicator
The memory flush path extracted tool_calls from the response assuming
OpenAI format (response.choices[0].message.tool_calls). When using
the Anthropic client directly (aux unavailable), the response is an
Anthropic Message object which has no .choices attribute. Now uses
normalize_anthropic_response() to extract tool_calls correctly.
- quickstart.md: Add Anthropic to the provider comparison table
- configuration.md: Add Anthropic to provider list table, add full
'Anthropic (Native)' section with three auth methods (API key,
setup-token, Claude Code auto-detect), config.yaml example,
and provider alias tip
- environment-variables.md: Add ANTHROPIC_API_KEY, ANTHROPIC_TOKEN,
CLAUDE_CODE_OAUTH_TOKEN to LLM Providers table; add 'anthropic'
to HERMES_INFERENCE_PROVIDER values list
Remaining issues from deep scan:
Adapter (agent/anthropic_adapter.py):
- Add _sanitize_tool_id() — Anthropic requires IDs matching [a-zA-Z0-9_-],
now strips invalid chars and ensures non-empty (both tool_use and tool_result)
- Empty tool result content → '(no output)' placeholder (Anthropic rejects empty)
- Set temperature=1 when thinking type='enabled' on older models (required)
- normalize_model_name now case-insensitive for 'Anthropic/' prefix
- Fix stale docstrings referencing only ~/.claude/.credentials.json
Agent loop (run_agent.py):
- Guard memory flush path (line ~2684) — was calling self.client.chat.completions
which is None in anthropic_messages mode. Now routes through Anthropic client.
- Guard summary generation path (line ~3171) — same crash when reaching
iteration limit. Now builds proper Anthropic kwargs and normalizes response.
- Guard retry summary path (line ~3200) — same fix for the summary retry loop.
All three self.client.chat.completions.create() calls outside the main
loop now have anthropic_messages branches to prevent NoneType crashes.
Fixes from comprehensive code review and cross-referencing with
clawdbot/OpenCode implementations:
CRITICAL:
- Add one-shot guard (anthropic_auth_retry_attempted) to prevent
infinite 401 retry loops when credentials keep changing
- Fix _is_oauth_token(): managed keys from ~/.claude.json are NOT
regular API keys (don't start with sk-ant-api). Inverted the logic:
only sk-ant-api* is treated as API key auth, everything else uses
Bearer auth + oauth beta headers
HIGH:
- Wrap json.loads(args) in try/except in message conversion — malformed
tool_call arguments no longer crash the entire conversation
- Raise AuthError in runtime_provider when no Anthropic token found
(was silently passing empty string, causing confusing API errors)
- Remove broken _try_anthropic() from auxiliary vision chain — the
centralized router creates an OpenAI client for api_key providers
which doesn't work with Anthropic's Messages API
MEDIUM:
- Handle empty assistant message content — Anthropic rejects empty
content blocks, now inserts '(empty)' placeholder
- Fix setup.py existing_key logic — set to 'KEEP' sentinel instead
of None to prevent falling through to the auth choice prompt
- Add debug logging to _fetch_anthropic_models on failure
Tests: 43 adapter tests (2 new for token detection), 3197 total passed
- Add _fetch_anthropic_models() to hermes_cli/models.py — hits the
Anthropic /v1/models endpoint to get the live model catalog. Handles
both API key and OAuth token auth headers.
- Wire it into provider_model_ids() so both 'hermes model' and
'hermes setup model' show the live list instead of a stale static one.
- Update static _PROVIDER_MODELS fallback with full current catalog:
opus-4-6, sonnet-4-6, opus-4-5, sonnet-4-5, opus-4, sonnet-4, haiku-4-5
- Update model_metadata.py with context lengths for all current models.
- Fix thinking parameter for 4.5+ models: use type='adaptive' instead
of type='enabled' (Anthropic deprecated 'enabled' for newer models,
warns at runtime). Detects model version from the model name string.
Verified live:
hermes model → Anthropic → auto-detected creds → shows 7 live models
hermes chat --provider anthropic --model claude-opus-4-6 → works
The critical bug: read_claude_code_credentials() only looked at
~/.claude/.credentials.json, but Claude Code's native binary (v2.x,
Bun-compiled) stores credentials in ~/.claude.json at the top level
as 'primaryApiKey'. The .credentials.json file is only written by
older npm-based installs.
Now checks both locations in priority order:
1. ~/.claude.json → primaryApiKey (native binary, v2.x)
2. ~/.claude/.credentials.json → claudeAiOauth.accessToken (legacy)
Verified live: hermes model → Anthropic → auto-detected credentials →
claude-sonnet-4-20250514 → 'Hello there, how are you?' (5 words)
Both 'hermes model' and 'hermes setup model' now present a clear
two-option auth flow when no credentials are found:
1. Claude Pro/Max subscription (setup-token)
- Step-by-step instructions to run 'claude setup-token'
- User pastes the resulting sk-ant-oat01-... token
2. Anthropic API key (pay-per-token)
- Link to console.anthropic.com/settings/keys
- User pastes sk-ant-api03-... key
Also handles:
- Auto-detection of existing Claude Code creds (~/.claude/.credentials.json)
- Existing credentials shown with option to update
- Consistent UX between 'hermes model' and 'hermes setup model'
* fix: stop rejecting unlisted models + auto-detect from /models endpoint
validate_requested_model() now accepts models not in the provider's API
listing with a warning instead of blocking. Removes hardcoded catalog
fallback for validation — if API is unreachable, accepts with a warning.
Model selection flows (setup + /model command) now probe the provider's
/models endpoint to get the real available models. Falls back to
hardcoded defaults with a clear warning when auto-detection fails:
'Could not auto-detect models — use Custom model if yours isn't listed.'
Z.AI setup no longer excludes GLM-5 on coding plans.
* fix: use hermes-agent.nousresearch.com as HTTP-Referer for OpenRouter
OpenRouter scrapes the favicon/logo from the HTTP-Referer URL for app
rankings. We were sending the GitHub repo URL, which gives us a generic
GitHub logo. Changed to the proper website URL so our actual branding
shows up in rankings.
Changed in run_agent.py (main agent client) and auxiliary_client.py
(vision/summarization clients).
Feedback fixes:
1. Revert _convert_vision_content — vision is handled by the vision_analyze
tool, not by converting image blocks inline in conversation messages.
Removed the function and its tests.
2. Add Anthropic to 'hermes model' (cmd_model in main.py):
- Added to provider_labels dict
- Added to providers selection list
- Added _model_flow_anthropic() with Claude Code credential auto-detection,
API key prompting, and model selection from catalog.
3. Wire up Anthropic as a vision-capable auxiliary provider:
- Added _try_anthropic() to auxiliary_client.py using claude-sonnet-4
as the vision model (Claude natively supports multimodal)
- Added to the get_vision_auxiliary_client() auto-detection chain
(after OpenRouter/Nous, before Codex/custom)
Cache tracking note: the Anthropic cache metrics branch in run_agent.py
(cache_read_input_tokens / cache_creation_input_tokens) is in the correct
place — it's response-level parsing, same location as the existing
OpenRouter cache tracking. auxiliary_client.py has no cache tracking.
Three bugs fixed in the Slack adapter:
1. Tool progress messages leaked to main channel instead of thread.
Root cause: metadata key mismatch — gateway uses 'thread_id' but
Slack adapter checked for 'thread_ts'. Added _resolve_thread_ts()
helper that checks both keys with correct precedence.
2. Bot responses could escape threads for replies.
Root cause: reply_to was set to the child message's ts, but Slack
API needs the parent message's ts for thread_ts. Now metadata
thread_id (always the parent ts) takes priority over reply_to.
3. All Slack DMs shared one session key ('agent:main:slack:dm'),
so a long-running task blocked all other DM conversations.
Fix: DMs with thread_id now get per-thread session keys. Top-level
DMs still share one session for conversation continuity.
Additional fix: All Slack media methods (send_image, send_voice,
send_video, send_document, send_image_file) now accept metadata
parameter for thread routing. Previously they only accepted reply_to,
which caused media to silently fail to post in threads.
Session key behavior after this change:
- Slack channel @mention: creates thread, thread = session
- Slack thread reply: stays in thread, same session
- Slack DM (top-level): one continuous session
- Slack DM (threaded): per-thread session
- Other platforms: unchanged
* fix: use session_key instead of chat_id for adapter interrupt lookups
monitor_for_interrupt() in _run_agent was using source.chat_id to query
the adapter's has_pending_interrupt() and get_pending_message() methods.
But the adapter stores interrupt events under build_session_key(source),
which produces a different string (e.g. 'agent:main:telegram:dm' vs '123456').
This key mismatch meant the interrupt was never detected through the
adapter path, which is the only active interrupt path for all adapter-based
platforms (Telegram, Discord, Slack, etc.). The gateway-level interrupt
path (in dispatch_message) is unreachable because the adapter intercepts
the 2nd message in handle_message() before it reaches dispatch_message().
Result: sending a new message while subagents were running had no effect —
the interrupt was silently lost.
Fix: replace all source.chat_id references in the interrupt-related code
within _run_agent() with the session_key parameter, which matches the
adapter's storage keys.
Also adds regression tests verifying session_key vs chat_id consistency.
* debug: add file-based logging to CLI interrupt path
Temporary instrumentation to diagnose why message-based interrupts
don't seem to work during subagent execution. Logs to
~/.hermes/interrupt_debug.log (immune to redirect_stdout).
Two log points:
1. When Enter handler puts message into _interrupt_queue
2. When chat() reads it and calls agent.interrupt()
This will reveal whether the message reaches the queue and
whether the interrupt is actually fired.
* fix: accept unlisted models with warning instead of rejecting
validate_requested_model() previously hard-rejected any model not found
in the provider's API listing. This was too aggressive — users on higher
plan tiers (e.g. Z.AI Pro/Max) may have access to models not shown in
the public listing (like glm-5 on coding endpoints).
Changes:
- validate_requested_model: accept unlisted models with a warning note
instead of blocking. The model is saved to config and used immediately.
- Z.AI setup: always offer glm-5 in the model list regardless of whether
a coding endpoint was detected. Pro/Max plans support it.
- Z.AI setup detection message: softened from 'GLM-5 is not available'
to 'GLM-5 may still be available depending on your plan tier'
After studying clawdbot (OpenClaw) and OpenCode implementations:
## Beta headers
- Add interleaved-thinking-2025-05-14 and fine-grained-tool-streaming-2025-05-14
as common betas (sent with ALL auth types, not just OAuth)
- OAuth tokens additionally get oauth-2025-04-20
- API keys now also get the common betas (previously got none)
## Vision/image support
- Add _convert_vision_content() to convert OpenAI multimodal format
(image_url blocks) to Anthropic format (image blocks with base64/url source)
- Handles both data: URIs (base64) and regular URLs
## Role alternation enforcement
- Anthropic strictly rejects consecutive same-role messages (400 error)
- Add post-processing step that merges consecutive user/assistant messages
- Handles string, list, and mixed content types during merge
## Tool choice support
- Add tool_choice parameter to build_anthropic_kwargs()
- Maps OpenAI values: auto→auto, required→any, none→omit, name→tool
## Cache metrics tracking
- Anthropic uses cache_read_input_tokens / cache_creation_input_tokens
(different from OpenRouter's prompt_tokens_details.cached_tokens)
- Add api_mode-aware branch in run_agent.py cache stats logging
## Credential refresh on 401
- On 401 error during anthropic_messages mode, re-read credentials
via resolve_anthropic_token() (picks up refreshed Claude Code tokens)
- Rebuild client if new token differs from current one
- Follows same pattern as Codex/Nous 401 refresh handlers
## Tests
- 44 adapter tests (8 new: vision conversion, role alternation, tool choice)
- Updated beta header tests to verify new structure
- Full suite: 3198 passed, 0 regressions
Root cause: two issues combined to create visual spam on Telegram/Discord:
1. build_tool_preview() preserved newlines from tool arguments. A preview
like 'import os\nprint("...")' rendered as 2+ visual lines per
progress entry on messaging platforms. This affected execute_code most
(code always has newlines), but could also hit terminal, memory,
send_message, session_search, and process tools.
2. No deduplication of identical progress messages. When models iterate
with execute_code using the same boilerplate code (common pattern),
each call produced an identical progress line. 9 calls x 2 visual
lines = 18 lines of identical spam in one message bubble.
Fixes:
- Added _oneline() helper to collapse all whitespace (newlines, tabs) to
single spaces. Applied to ALL code paths in build_tool_preview() —
both the generic path and every early-return path that touches user
content (memory, session_search, send_message, process).
- Added dedup in gateway progress_callback: consecutive identical messages
are collapsed with a repeat counter, e.g. 'execute_code: ... (x9)'
instead of 9 identical lines. The send_progress_messages async loop
handles dedup tuples by updating the last progress_line in-place.
* fix: ClawHub skill install — use /download ZIP endpoint
The ClawHub API v1 version endpoint only returns file metadata
(path, size, sha256, contentType) without inline content or download
URLs. Our code was looking for inline content in the metadata, which
never existed, causing all ClawHub installs to fail with:
'no inline/raw file content was available'
Fix: Use the /api/v1/download endpoint (same as the official clawhub
CLI) to download skills as ZIP bundles and extract files in-memory.
Changes:
- Add _download_zip() method that downloads and extracts ZIP bundles
- Retry on 429 rate limiting with Retry-After header support
- Path sanitization and binary file filtering for security
- Keep _extract_files() as a fallback for inline/raw content
- Also fix nested file lookup (version_data.version.files)
* chore: lower default compression threshold from 85% to 50%
Triggers context compression earlier — at 50% of the model's context
window instead of 85%. Updated in all four places where the default
is defined: context_compressor.py, cli.py, run_agent.py, config.py,
and gateway/run.py.
The tinker-atropos submodule and its heavy dependencies (atroposlib, tinker,
wandb, fastapi, uvicorn) were being installed for all users by default,
adding significant install time and disk usage for most users who don't
need RL training capabilities.
Changes:
- install.sh: Only init mini-swe-agent submodule by default; skip
tinker-atropos clone and install entirely
- install.sh: Remove --recurse-submodules from git clone (only fetches
what's needed)
- pyproject.toml: Add [rl] optional dependency group for explicit opt-in
- rl_training_tool.py: Move LOGS_DIR.mkdir() from module-level to lazy
init (_ensure_logs_dir) to avoid side effects on import
- README.md: Update contributor quick start to not auto-fetch
tinker-atropos; add RL opt-in instructions
Users who want RL training can opt in with:
git submodule update --init tinker-atropos
uv pip install -e ./tinker-atropos

Mistral's API strictly validates the Chat Completions schema and rejects
unknown fields (call_id, response_item_id) with 422. These fields are
added by _build_assistant_message() for Codex Responses API support.
This fix:
- Only strips when targeting Mistral (api.mistral.ai in base_url)
- Creates new tool_call dicts instead of mutating originals (shallow
copy safety — msg.copy() shares the tool_calls list)
- Preserves call_id/response_item_id in the internal message history
so _chat_messages_to_responses_input() can still read them if the
session falls back to a Codex provider mid-conversation
Applied in all 3 API message building locations:
- Main conversation loop (run_conversation)
- _handle_max_iterations()
- flush_memories()
Inspired by PR #864 (unmodeled-tyler) which identified the issue but
applied the fix unconditionally and mutated originals via shallow copy.
