start_gateway() now checks for an existing running instance via PID file
before starting. If another gateway is already running under the same
HERMES_HOME, it refuses to start with a clear error message directing the
user to 'hermes gateway restart' or 'hermes gateway stop'.
Also fixes gateway/status.py to respect the HERMES_HOME env var instead of
hardcoding ~/.hermes. This scopes the PID file per HERMES_HOME directory,
which lays the groundwork for future multi-profile support where distinct
HERMES_HOME directories can run concurrent gateway instances independently.
The original implementation only supported xclip (X11), which silently
fails on WSL2 (can't access Windows clipboard for images), Wayland
desktops (xclip is X11-only), and VSCode terminal on WSL2.
Clipboard backend changes (hermes_cli/clipboard.py):
- WSL2: detect via /proc/version, use powershell.exe with .NET
System.Windows.Forms.Clipboard to extract images as base64 PNG
- Wayland: use wl-paste with MIME type detection, auto-convert BMP
to PNG for WSLg environments (via Pillow or ImageMagick)
- Dispatch order: WSL → Wayland → X11 (xclip), with fallthrough
- New has_clipboard_image() for lightweight clipboard checks
- Cache WSL detection result per-process
CLI changes (cli.py):
- /paste command: explicit clipboard image check for terminals where
BracketedPaste doesn't fire (image-only clipboard in VSCode/WinTerm)
- Ctrl+V keybinding: fallback for Linux terminals where Ctrl+V sends
raw byte instead of triggering bracketed paste
Tests: 80 tests (up from 37) covering WSL, Wayland, X11 dispatch,
BMP conversion, has_clipboard_image, and /paste command.
Copy an image to clipboard (screenshot, browser, etc.) and paste into
the Hermes CLI. The image is saved to ~/.hermes/images/, shown as a
badge above the input ([📎 Image #1]), and sent to the model as a
base64-encoded OpenAI vision multimodal content block.
Implementation:
- hermes_cli/clipboard.py: clean module with platform-specific extraction
- macOS: pngpaste (if installed) → osascript fallback (always available)
- Linux: xclip (apt install xclip)
- cli.py: BracketedPaste key handler checks clipboard on every paste,
image bar widget shows attached images, chat() converts to multimodal
content format, Ctrl+C clears attachments
Inspired by @m0at's fork (https://github.com/m0at/hermes-agent) which
implemented image paste support for local vision models. Reimplemented
cleanly as a separate module with tests.
Authored by alireza78a. When flock() raises on a concurrent tick, the
file descriptor was leaked because the except clause returned without
closing it. Adds lock_fd=None init and close in the except path.
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
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.
- Installation: Remove PowerShell/CMD install commands, add WSL2 warning
- Quickstart: Replace PowerShell block with WSL2 tip
- Contributing: Update cross-platform section to clarify Windows unsupported
- Index: Update install description to say WSL2 instead of Windows
- Remove PowerShell and CMD tabs from hero and install sections
- Add WSL to the Linux/macOS tab label
- Update Windows notice: experimental/unsupported, recommend WSL2
- Add Docs nav link pointing to /docs/

- 25 documentation pages covering Getting Started, User Guide, Developer Guide, and Reference
- Docusaurus with custom amber/gold theme matching the landing page branding
- GitHub Actions workflow to deploy landing page + docs to GitHub Pages
- Landing page at root, docs at /docs/ on hermes-agent.nousresearch.com
- Content extracted and restructured from existing repo docs (README, AGENTS.md, CONTRIBUTING.md, docs/)
- Auto-deploy on push to main when website/ or landingpage/ changes
Building on PR #288's edit_message() abstraction:
- Telegram: edit_message_text() with MarkdownV2 + plain text fallback
- Discord: channel.fetch_message() + msg.edit() with length capping
- Slack: chat_update() via slack_bolt client
Also fixes the fallback regression in send_progress_messages() where
platforms that don't support editing would receive duplicated accumulated
tool lines. Now uses a can_edit flag — after the first failed edit, falls
back to sending individual lines (matching pre-PR behavior).
Authored by satelerd. Adds edit_message() to BasePlatformAdapter and
implements it for WhatsApp via Baileys native editing. Progress messages
accumulate into a single live-updating message instead of N separate ones.
Cherry-picked from stale branch.
Instead of sending a separate WhatsApp message for each tool call during
agent execution (N+1 messages), the first tool sends a new message and
subsequent tools edit it to append their line. Result: 1 growing progress
message + 1 final response = 2 messages instead of N+1.
Changes:
- bridge.js: Add POST /edit endpoint using Baileys message editing
- base.py: Add optional edit_message() to BasePlatformAdapter (no-op
default, so platforms without editing support work unchanged)
- whatsapp.py: Implement edit_message() calling bridge /edit
- run.py: Rewrite send_progress_messages() to accumulate tool lines and
edit the progress message. Falls back to sending a new message if
edit fails (graceful degradation).

Authored by rovle. Passes session_id as task_id to run_conversation()
in both CLI and gateway, so container backends (Docker/Modal/Singularity)
reuse the same sandbox across turns. Also passes task_id through to
_create_environment() in file_tools.py.
Cherry-picked from original PR branch (which had unrelated divergent
commits from the contributor's fork).
Authored by jdblackstar. Catches runtime exceptions from TerminalMenu
init (e.g. CalledProcessError from tput with unknown TERM like
xterm-ghostty over SSH) and falls through to the text-based menu.
Adds a /update command to Telegram, Discord, and other gateway platforms
that runs `hermes update` to pull the latest code, update dependencies,
sync skills, and restart the gateway.
Implementation:
- Spawns `hermes update` in a separate systemd scope (systemd-run --user
--scope) so the process survives the gateway restart that hermes update
triggers at the end. Falls back to nohup if systemd-run is unavailable.
- Writes a marker file (.update_pending.json) with the originating
platform and chat_id before spawning the update.
- On gateway startup, _send_update_notification() checks for the marker,
reads the captured update output, sends the results back to the user,
and cleans up.
Also:
- Registers /update as a Discord slash command
- Updates README.md, docs/messaging.md, docs/slash-commands.md
- Adds 18 tests covering handler, notification, and edge cases
