A single Telegram 409 Conflict from getUpdates permanently killed
Telegram polling with no recovery possible (retryable=False on
first occurrence). This is too aggressive for production use with
process supervisors.
Transient 409s are expected during:
- --replace handoffs where the old long-poll session lingers on
Telegram servers for a few seconds after SIGTERM
- systemd Restart=on-failure respawns that overlap with the dying
instance cleanup
Now _handle_polling_conflict() retries up to 3 times with a
10-second delay between attempts. The 30-second total retry window
lets stale server-side sessions expire. If all retries fail, the
error is still marked as permanently fatal — preserving the original
protection against genuine dual-instance conflicts.
Tests updated: split the single conflict test into two — one verifying
retry on transient conflict, one verifying fatal after exhausted
retries.
Closes#2296
- Convert ~~text~~ to ~text~ (MarkdownV2 strikethrough)
- Protect ||text|| from pipe escaping (MarkdownV2 spoiler)
- Preserve > at line start as blockquote instead of escaping it
- Update _strip_mdv2() to strip ~strikethrough~ and ||spoiler|| markers
- Add tests covering new formatting paths and edge cases
Stream consumer now splits messages that exceed the platform's
MAX_MESSAGE_LENGTH. When accumulated text grows past the safe limit,
the current message is finalized and a new message is started for the
overflow — same as how normal sends chunk long responses.
Split point prefers line boundaries (rfind newline) for clean breaks.
Works for all platforms (Telegram 4096, Discord 2000, etc.) by reading
the adapter's MAX_MESSAGE_LENGTH at runtime.
Also added a safety net in the Telegram adapter: if edit_message_text
still hits MESSAGE_TOO_LONG (e.g. markdown formatting expansion), it
truncates and returns success so the stream consumer doesn't die.

* fix: NameError in OpenCode provider setup (prompt_text -> prompt)
The OpenCode Zen and OpenCode Go setup sections used prompt_text()
which is undefined. All other providers correctly use the local
prompt() function defined in setup.py. Fixes crash during
'hermes setup' when selecting either OpenCode provider.
* fix: Telegram streaming — config bridge, not-modified, flood control
Three fixes for gateway streaming:
1. Bridge streaming config from config.yaml into gateway runtime.
load_gateway_config() now reads the 'streaming' key from config.yaml
(same pattern as session_reset, stt, etc.), matching the docs.
Previously only gateway.json was read.
2. Handle 'Message is not modified' in Telegram edit_message().
This Telegram API error fires when editing with identical content —
a no-op, not a real failure. Previously it returned success=False
which made the stream consumer disable streaming entirely.
3. Handle RetryAfter / flood control in Telegram edit_message().
Fast providers can hit Telegram rate limits during streaming.
Now waits the requested retry_after duration and retries once,
instead of treating it as a fatal edit failure.
Also fixed double-edit on stream finish: the consumer now tracks
last-sent text and skips redundant edits, preventing the not-modified
error at the source.
* refactor: make config.yaml the primary gateway config source
Eliminates the per-key bridge pattern in load_gateway_config().
Previously gateway.json was the primary source and each config.yaml
key needed an individual bridge — easy to forget (streaming was
missing, causing garl4546's bug).
Now config.yaml is read first and its keys are mapped directly into
the GatewayConfig.from_dict() schema. gateway.json is kept as a
legacy fallback layer (loaded first, then overwritten by config.yaml
keys). If gateway.json exists, a log message suggests migrating.
Also:
- Removed dead save_gateway_config() (never called anywhere)
- Updated CLI help text and send_message error to reference
config.yaml instead of gateway.json

When a user sends a long message, Telegram clients split it into
multiple updates that arrive within milliseconds of each other.
Previously each chunk was dispatched independently — the first would
start the agent, and subsequent chunks would interrupt or queue as
separate turns, causing the agent to only see part of the message.
Add text message batching to TelegramAdapter following the same pattern
as the existing photo burst batching:
- _enqueue_text_event() buffers text by session key, concatenating
chunks that arrive in rapid succession
- _flush_text_batch() dispatches the combined message after a 0.6s
quiet period (configurable via HERMES_TELEGRAM_TEXT_BATCH_DELAY_SECONDS)
- Timer resets on each new chunk, so all parts of a split arrive
before the batch is dispatched
Reported by NulledVector on Discord.
* 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.).
Cherry-picked from PR #1562 by ygd58.
* fix(tools): chunk long messages in send_message_tool before dispatch (#1552)
Long messages sent via send_message tool or cron delivery silently
failed when exceeding platform limits. Gateway adapters handle this
via truncate_message(), but the standalone senders in send_message_tool
bypassed that entirely.
- Apply truncate_message() chunking in _send_to_platform() before
dispatching to individual platform senders
- Remove naive message[i:i+2000] character split in _send_discord()
in favor of centralized smart splitting
- Attach media files to last chunk only for Telegram
- Add regression tests for chunking and media placement
Cherry-picked from PR #1557 by llbn.
* fix(approval): show full command in dangerous command approval (#1553)
Previously the command was truncated to 80 chars in CLI (with a
[v]iew full option), 500 chars in Discord embeds, and missing entirely
in Telegram/Slack approval messages. Now the full command is always
displayed everywhere:
- CLI: removed 80-char truncation and [v]iew full menu option
- Gateway (TG/Slack): approval_required message includes full command
in a code block
- Discord: embed shows full command up to 4096-char limit
- Windows: skip SIGALRM-based test timeout (Unix-only)
- Updated tests: replaced view-flow tests with direct approval tests
Cherry-picked from PR #1566 by crazywriter1.
* fix(cli): flush stdout during agent loop to prevent macOS display freeze (#1624)
The interrupt polling loop in chat() waited on the queue without
invalidating the prompt_toolkit renderer. On macOS, the StdoutProxy
buffer only flushed on input events, causing the CLI to appear frozen
during tool execution until the user typed a key.
Fix: call _invalidate() on each queue timeout (every ~100ms, throttled
to 150ms) to force the renderer to flush buffered agent output.
* fix(claw): warn when API keys are skipped during OpenClaw migration (#1580)
When --migrate-secrets is not passed (the default), API keys like
OPENROUTER_API_KEY are silently skipped with no warning. Users don't
realize their keys weren't migrated until the agent fails to connect.
Add a post-migration warning with actionable instructions: either
re-run with --migrate-secrets or add the key manually via
hermes config set.
Cherry-picked from PR #1593 by ygd58.
* fix(security): block sandbox backend creds from subprocess env (#1264)
Add Modal and Daytona sandbox credentials to the subprocess env
blocklist so they're not leaked to agent terminal sessions via
printenv/env.
Cherry-picked from PR #1571 by ygd58.
* fix(gateway): cap interrupt recursion depth to prevent resource exhaustion (#816)
When a user sends multiple messages while the agent keeps failing,
_run_agent() calls itself recursively with no depth limit. This can
exhaust stack/memory if the agent is in a failure loop.
Add _MAX_INTERRUPT_DEPTH = 3. When exceeded, the pending message is
logged and the current result is returned instead of recursing deeper.
The log handler duplication bug described in #816 was already fixed
separately (AIAgent.__init__ deduplicates handlers).
* fix(gateway): /model shows active fallback model instead of config default (#1615)
When the agent falls back to a different model (e.g. due to rate
limiting), /model still showed the config default. Now tracks the
effective model/provider after each agent run and displays it.
Cleared when the primary model succeeds again or the user explicitly
switches via /model.
Cherry-picked from PR #1616 by MaxKerkula. Added hasattr guard for
test compatibility.
* feat(gateway): inject reply-to message context for out-of-session replies (#1594)
When a user replies to a Telegram message, check if the quoted text
exists in the current session transcript. If missing (from cron jobs,
background tasks, or old sessions), prepend [Replying to: "..."] to
the message so the agent has context about what's being referenced.
- Add reply_to_text field to MessageEvent (base.py)
- Populate from Telegram's reply_to_message (text or caption)
- Inject context in _handle_message when not found in history
Based on PR #1596 by anpicasso (cherry-picked reply-to feature only,
excluded unrelated /server command and background delegation changes).

* refactor: centralize slash command registry
Replace 7+ scattered command definition sites with a single
CommandDef registry in hermes_cli/commands.py. All downstream
consumers now derive from this registry:
- CLI process_command() resolves aliases via resolve_command()
- Gateway _known_commands uses GATEWAY_KNOWN_COMMANDS frozenset
- Gateway help text generated by gateway_help_lines()
- Telegram BotCommands generated by telegram_bot_commands()
- Slack subcommand map generated by slack_subcommand_map()
Adding a command or alias is now a one-line change to
COMMAND_REGISTRY instead of touching 6+ files.
Bugfixes included:
- Telegram now registers /rollback, /background (were missing)
- Slack now has /voice, /update, /reload-mcp (were missing)
- Gateway duplicate 'reasoning' dispatch (dead code) removed
- Gateway help text can no longer drift from CLI help
Backwards-compatible: COMMANDS and COMMANDS_BY_CATEGORY dicts are
rebuilt from the registry, so existing imports work unchanged.
* docs: update developer docs for centralized command registry
Update AGENTS.md with full 'Slash Command Registry' and 'Adding a
Slash Command' sections covering CommandDef fields, registry helpers,
and the one-line alias workflow.
Also update:
- CONTRIBUTING.md: commands.py description
- website/docs/reference/slash-commands.md: reference central registry
- docs/plans/centralize-command-registry.md: mark COMPLETED
- plans/checkpoint-rollback.md: reference new pattern
- hermes-agent-dev skill: architecture table
* chore: remove stale plan docs
Add exponential-backoff retry (3 attempts) around initialize() to
handle transient TLS resets during gateway startup. Also catches
TimedOut and OSError in addition to NetworkError.
Add exponential-backoff retry (3 attempts) around send_message() for
NetworkError during message delivery, wrapping the existing Markdown
fallback logic.
Both imports are guarded with try/except ImportError for test
environments where telegram is mocked.
Based on PR #1527 by cmd8. Closes#1526.
default group and channel sessions to per-user isolation, allow opting back into shared room sessions via config.yaml, and document Discord gateway routing and session behavior.
The disconnect() method was unconditionally calling updater.stop() and
app.stop(), causing errors when:
- The updater was not running (RuntimeError: This Updater is not running!)
- The app was None (AttributeError: 'NoneType' object has no attribute)
Changes:
- Check if updater exists and is running before stopping
- Check if app is running before stopping
- Only log warnings for actual errors, not expected shutdown states
Fixes spurious warnings during gateway shutdown.
Cancel any queued media-group flush tasks during Telegram adapter disconnect
and clear the buffered events map so shutdown can't leave a pending album
flush behind. Add a regression test covering disconnect before the debounce
window expires.
Telegram albums arrive as multiple updates with a shared media_group_id.
Previously each image triggered a separate MessageEvent, causing the agent
to interrupt itself when describing the first image.
- Add 0.8s debounce window for media group items
- Merge attachments into single MessageEvent
- Add regression test for photo album buffering
Remove web UI gateway (web.py, tests, docs, toolset, env vars, Platform.WEB
enum) per maintainer request — Nous is building their own official chat UI.
Fix 1: Replace sd.wait() with polling pattern in play_audio_file() to prevent
indefinite hang when audio device stalls (consistent with play_beep()).
Fix 2: Use importlib.util.find_spec() for faster_whisper/openai availability
checks instead of module-level imports that trigger heavy native library
loading (CUDA/cuDNN) at import time.
Fix 3: Remove inspect.signature() hack in _send_voice_reply() — add **kwargs
to Telegram send_voice() so all adapters accept metadata uniformly.
Fix 4: Make session loading resilient to removed platform enum values — skip
entries with unknown platforms instead of crashing the entire gateway.
- /voice on: reply with voice when user sends voice messages
- /voice tts: reply with voice to all messages
- /voice off: disable, text-only replies
- /voice status: show current mode
- Per-chat state persisted to gateway_voice_mode.json
- Dedup: skips auto-reply if agent already called text_to_speech tool
- drop_pending_updates=True to ignore stale Telegram messages on restart
- 25 tests covering command handler, reply logic, and edge cases
Add a /reasoning command across gateway adapters so users can
inspect or change reasoning effort without editing config by hand.
Reload reasoning settings from config.yaml before each agent run,
including background tasks, so the next message picks up the new
value consistently.
The MEDIA routing in _process_message_background passes
metadata=_thread_metadata to send_video, send_document, and
send_image_file — but none accepted it, causing TypeError silently
caught by the except handler. Files just failed to send.
Fix: add **kwargs to all four base class media methods and their
Telegram overrides.
Authored by aydnOktay. Replaces print() statements with structured
logging calls (error/warning/info/debug) throughout the Telegram
adapter. Adds exc_info=True for stack traces on failures.
Part 2 of thread_id forum topic fix: add metadata param to
send_voice, send_image, send_animation, send_typing in Telegram
adapter and pass message_thread_id to all Bot API calls. Update
send_typing signature in Discord, Slack, WhatsApp, HomeAssistant
for compatibility.
Based on the fix proposed by @Bitstreamono in PR #656.
Implement send_document() and send_video() overrides in TelegramAdapter
so the agent can deliver files (PDFs, CSVs, docs, etc.) and videos as
native Telegram attachments instead of just printing the file path as
text.
The base adapter already routes MEDIA:<path> tags by extension — audio
goes to send_voice(), images to send_image_file(), and everything else
falls through to send_document(). But TelegramAdapter didn't override
send_document() or send_video(), so those fell back to plain text.
Now when the agent includes MEDIA:/path/to/report.pdf in its response,
users get a proper downloadable file attachment in Telegram.
Features:
- send_document: sends files via bot.send_document with display name,
caption (truncated to 1024), and reply_to support
- send_video: sends videos via bot.send_video with inline playback
- Both fall back to base class text if the Telegram API call fails
- 10 new tests covering success, custom filename, file-not-found,
not-connected, caption truncation, API error fallback, and reply_to
Requested by @TigerHixTang on Twitter.
Adds a 'find-nearby' skill for discovering nearby places using
OpenStreetMap (Overpass + Nominatim). No API keys needed. Works with:
- Coordinates (from Telegram location pins)
- Addresses, cities, zip codes, landmarks (auto-geocoded)
- Multiple place types (restaurant, cafe, bar, pharmacy, etc.)
Returns names, distances, cuisine, hours, addresses, and Google Maps
links (pin + directions). 184-line stdlib-only script.
Also adds Telegram location message handling:
- New MessageType.LOCATION in gateway base
- Telegram adapter handles LOCATION and VENUE messages
- Injects lat/lon coordinates into conversation context
- Prompts agent to ask what the user wants nearby
Inspired by PR #422 (reimplemented with simpler script and broader
skill scope — addresses/cities/zips, not just Telegram coordinates).
Telegram: add /insights, /update, /reload_mcp (underscore variant since
Telegram BotCommand names don't allow hyphens).
Discord: add /insights (with days parameter), /reload-mcp.
Also add reload_mcp as an alias for reload-mcp in the gateway command
dispatcher so Telegram's underscore form works, and add resume/provider
to the _known_commands set for hook emission.
Add /title, /resume, /compress, /provider, /usage to Telegram's
set_my_commands so they appear in the / autocomplete menu.
Add /title, /resume, /compress, /provider, /usage, /help as Discord
slash commands so they appear in Discord's native command picker.
These commands were functional via text but not registered with the
platform-native command menus, so users couldn't discover them.
browser_vision now saves screenshots persistently to ~/.hermes/browser_screenshots/
and returns the screenshot_path in its JSON response. The model can include
MEDIA:<path> in its response to share screenshots as native photos.
Changes:
- browser_tool.py: Save screenshots persistently, return screenshot_path,
auto-cleanup files older than 24 hours, mkdir moved inside try/except
- telegram.py: Add send_image_file() — sends local images via bot.send_photo()
- discord.py: Add send_image_file() — sends local images via discord.File
- slack.py: Add send_image_file() — sends local images via files_upload_v2()
(WhatsApp already had send_image_file — no changes needed)
- prompt_builder.py: Updated Telegram hint to list image extensions,
added Discord and Slack MEDIA: platform hints
- browser.md: Document screenshot sharing and 24h cleanup
- send_file_integration_map.md: Updated to reflect send_image_file is now
implemented on Telegram/Discord/Slack
- test_send_image_file.py: 19 tests covering MEDIA: .png extraction,
send_image_file on all platforms, and screenshot cleanup
Partially addresses #466 (Phase 0: platform adapter gaps for send_image_file).
Telegram's send_photo via URL has a ~5MB limit. Upscaled images from
fal.ai's Clarity Upscaler often exceed this, causing 'Wrong type of
web page content' or 'Failed to get http url content' errors.
Fix: Add download-and-upload fallback in Telegram's send_image().
When URL-based send_photo fails, download the image via httpx and
re-upload as bytes (supports up to 10MB file uploads).
Also: convert print() to logger.warning/error in image sending path
for proper log visibility (print goes to socket, invisible in logs).
When MarkdownV2 parsing fails, _strip_mdv2() removes escape backslashes
and bold markers (*text*) but missed italic markers (_text_). Users saw
raw underscores around italic text in the plaintext fallback.
- Add regex to strip _text_ italic markers in _strip_mdv2()
- Use word boundary lookaround to preserve snake_case identifiers
- Add tests for _strip_mdv2 covering italic, bold, snake_case, and edge cases
When Telegram's MarkdownV2 parser rejects a message, the send() fallback
was sending the already-escaped text as plain text. This caused users to
see raw backslashes before every special character (periods, dashes,
parentheses, etc.) — e.g. 'sentence\.' or '\-\-auto\-approve'.
Changes:
- Add _strip_mdv2() to reverse MarkdownV2 escaping for clean plaintext
- Use stripped text in the send() fallback path instead of raw escaped chunk
- Add logging when the MDV2 fallback is triggered for diagnostics
- Add logger to telegram.py (was missing)
The edit_message() fallback already correctly used the original content;
this brings send() in line with that behavior.
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 0xbyt4.
The italic regex [^*]+ matched across newlines, corrupting bullet lists
using * markers (e.g. '* Item one\n* Item two' became italic garbage).
Fixed by adding \n to the negated character class: [^*\n]+.
The ImportError fallback set ContextTypes = Any, but then
ContextTypes.DEFAULT_TYPE was used as a type annotation at class
definition time — Any doesn't have .DEFAULT_TYPE, causing AttributeError.
Fix: create a _MockContextTypes class with DEFAULT_TYPE = Any.
Also stub CommandHandler, TelegramMessageHandler, filters, ParseMode,
and ChatType to prevent potential NameErrors.
Fixes#304.
The italic regex \*([^*]+)\* used [^*] which matches newlines, causing
bullet lists with * markers to be incorrectly converted to italic text.
Changed to [^*\n]+ to prevent cross-line matching.
Adds 43 tests for _escape_mdv2 and format_message covering code blocks,
bold/italic, headers, links, mixed formatting, and the regression case.
- Sanitize filenames in cache_document_from_bytes to prevent path traversal (strip directory components, null bytes, resolve check)
- Reject documents with None file_size instead of silently allowing download
- Cap text file injection at 100 KB to prevent oversized prompt payloads
- Sanitize display_name in run.py context notes to block prompt injection via filenames
- Add 35 unit tests covering document cache utilities and Telegram document handling
