On top of PR #460: self-hosted Firecrawl instances don't require an API
key (USE_DB_AUTHENTICATION=false), so don't force users to set a dummy
FIRECRAWL_API_KEY when FIRECRAWL_API_URL is set. Also adds a proper
self-hosting section to the configuration docs explaining what you get,
what you lose, and how to set it up (Docker stack, tradeoffs vs cloud).
Added 2 more tests (URL-only without key, neither-set raises).
Replaces the unsafe 128K fallback for unknown models with a descending
probe strategy (2M → 1M → 512K → 200K → 128K → 64K → 32K). When a
context-length error occurs, the agent steps down tiers and retries.
The discovered limit is cached per model+provider combo in
~/.hermes/context_length_cache.yaml so subsequent sessions skip probing.
Also parses API error messages to extract the actual context limit
(e.g. 'maximum context length is 32768 tokens') for instant resolution.
The CLI banner now displays the context window size next to the model
name (e.g. 'claude-opus-4 · 200K context · Nous Research').
Changes:
- agent/model_metadata.py: CONTEXT_PROBE_TIERS, persistent cache
(save/load/get), parse_context_limit_from_error(), get_next_probe_tier()
- agent/context_compressor.py: accepts base_url, passes to metadata
- run_agent.py: step-down logic in context error handler, caches on success
- cli.py + hermes_cli/banner.py: context length in welcome banner
- tests: 22 new tests for probing, parsing, and caching
Addresses #132. PR #319's approach (8K default) rejected — too conservative.
Adds optional FIRECRAWL_API_URL environment variable to support
self-hosted Firecrawl deployments alongside the cloud service.
- Add FIRECRAWL_API_URL to optional env vars in hermes_cli/config.py
- Update _get_firecrawl_client() in tools/web_tools.py to accept custom API URL
- Add tests for client initialization with/without URL
- Document new env var in installation and config guides
On Windows, open() defaults to the system locale encoding (cp1252,
cp1254, etc.) rather than UTF-8. This breaks any file containing
non-ASCII characters, and also causes crashes when writing JSON with
ensure_ascii=False.
This adds encoding="utf-8" to open() calls in:
- gateway/run.py (config.yaml reads/writes throughout)
- gateway/config.py (gateway.json and config.yaml)
- hermes_cli/config.py (config.yaml load/save)
- hermes_cli/main.py (session export with ensure_ascii=False)
- hermes_cli/status.py (jobs.json and sessions.json)
ptyprocess depends on Unix-only APIs (fork, openpty) and cannot work
on Windows at all. pywinpty provides a compatible PtyProcess interface
using the Windows ConPTY API.
This conditionally imports winpty.PtyProcess on Windows and
ptyprocess.PtyProcess on Unix. The pyproject.toml pty extra now uses
platform markers so the correct package is installed automatically.
fcntl is not available on Windows. This adds msvcrt.locking as a
fallback for cross-process advisory locking on Windows.
msvcrt.locking is not reentrant within the same thread, unlike fcntl.flock.
This matters because resolve_codex_runtime_credentials holds the lock and
then calls _save_codex_tokens, which tries to acquire it again. Without
reentrancy tracking, this deadlocks on Windows after a 15-second timeout.
Uses threading.local() to track lock depth per thread, allowing nested
acquisitions to pass through without re-acquiring the underlying lock.
Also handles msvcrt-specific requirements: file must be opened in r+ mode
(not a+), must have at least 1 byte of content, and the file pointer must
be at position 0 before locking.
The Daytona SDK's process.exec(timeout=N) parameter is not enforced —
the server-side timeout never fires and the SDK has no client-side
fallback, causing commands to hang indefinitely.
Fix: wrap commands with timeout N sh -c '...' (coreutils) which
reliably kills the process and returns exit code 124. Added
shlex.quote for proper shell escaping and a secondary deadline (timeout + 10s) that force-stops the sandbox if the shell timeout somehow fails.

When an LLM returns null/empty tool call arguments, json.loads()
produces None. build_tool_preview then crashes with
"argument of type 'NoneType' is not iterable" on the `in` check.
Return None early when args is falsy.

- Replace logger.warning with warnings.warn for the disk cap so users
actually see it (logger was suppressed by CLI's log level config)
- Use SandboxState enum instead of string literals in
_ensure_sandbox_ready

Add Daytona as a backend choice in the interactive setup wizard with
SDK installation and API key prompts. Show Daytona image in status
output and validate API key + SDK in doctor checks. Add OPTION 6
example in cli-config.yaml.example.

Add Daytona to image selection, container_config guards, environment
factory, requirements check, and diagnostics in terminal_tool.py and
file_tools.py. Also add to sandboxed-backend approval bypass.

Authored by 0xbyt4. Wraps commands with unique fence markers to isolate real output
from shell init/exit noise (oh-my-zsh, macOS session restore, etc.). Falls back to
expanded pattern-based cleaning. Also fixes BSD find fallback and test module shadowing.
Authored by PercyDikec. Fixes#437.
The retry path in _handle_max_iterations was missing the second if final_response:
guard after stripping <think> blocks, which could result in an empty assistant message
being appended to history instead of using the fallback message.
Authored by satelerd. Adds native WhatsApp media sending for images, videos,
and documents via MEDIA: tags. Also includes conflict resolution with edit_message
feature, Telegram hint fix (only advertise supported media types), and import cleanup.
Removed 10 markdown files (~4,200 lines) that have been fully migrated,
restructured, and accuracy-audited on the docs site at
hermes-agent.nousresearch.com/docs/
Left docs/README.md as a pointer to the website.
Updated CONTRIBUTING.md file tree reference.
Run pytest on Python 3.11 + 3.12 for every PR and push to main.
- Uses uv for fast dependency installation
- Excludes integration tests (need real API keys/services)
- Blanks API keys as safety net against accidental real API calls
- Concurrency: cancels in-progress runs when new commits are pushed
- 10 minute timeout (tests take ~77s)
- fail-fast disabled so both Python versions run independently
GitHub's default 'require approval for first-time contributors'
means maintainers approve CI before it runs on new contributors'
PRs, preventing abuse of CI resources.
Add a second checklist section covering common oversights seen in PRs:
- Update relevant docs (README, docs/, docstrings)
- Update cli-config.yaml.example when adding config keys
- Update CONTRIBUTING.md/AGENTS.md for architecture changes
- Consider cross-platform impact (Windows/macOS)
- Update tool schemas when changing tool behavior
Each item has an 'or N/A' option so contributors aren't blocked
on items that don't apply to their change.
The retry summary in _handle_max_iterations hardcodes max_tokens instead
of calling _max_tokens_param(). For direct OpenAI API users (gpt-4o,
o-series), the correct parameter name is max_completion_tokens. The first
attempt at line 2697 already uses _max_tokens_param correctly but the
retry path at line 2743 was missed.
