Before launching an MCP server via npx/uvx, queries the OSV (Open Source
Vulnerabilities) API to check if the package has known malware advisories
(MAL-* IDs). Regular CVEs are ignored — only confirmed malware is blocked.
- Free, public API (Google-maintained), ~300ms per query
- Runs once per MCP server launch, inside _run_stdio() before subprocess spawn
- Parallel with other MCP servers (asyncio.gather already in place)
- Fail-open: network errors, timeouts, unrecognized commands → allow
- Parses npm (scoped @scope/pkg@version) and PyPI (name[extras]==version)
Inspired by Block/goose extension malware check.
Add optional 'expression' parameter to browser_console that evaluates
JavaScript in the page context (like DevTools console). Returns structured
results with auto-JSON parsing.
No new tool — extends the existing browser_console schema with ~20 tokens
of overhead instead of adding a 12th browser tool.
Both backends supported:
- Browserbase: uses agent-browser 'eval' command via CDP
- Camofox: uses /tabs/{tab_id}/eval endpoint with graceful degradation
E2E verified: string eval, number eval, structured JSON, DOM manipulation,
error handling, and original console-output mode all working.
Only request the privileged members intent when DISCORD_ALLOWED_USERS includes non-numeric entries that need username resolution. Also release the Discord token lock when startup fails so retries and restarts are not blocked by a stale lock.\n\nAdds regression tests for conditional intents and startup lock cleanup.
Existing honcho.json configs without an explicit observationMode now
default to 'unified' (the old default) instead of being silently
switched to 'directional'. New installations get 'directional' as
the new default.
Detection: _explicitly_configured (host block exists or enabled=true)
signals an existing config. When true and no observationMode is set
anywhere in the config chain, falls back to 'unified'. When false
(fresh install), uses 'directional'.
Users who explicitly set observationMode or granular observation
booleans are unaffected — explicit config always wins.
5 new tests covering all migration paths.
discover_plugin_cli_commands() now reads memory.provider from config.yaml
and only loads CLI registration for the active provider. If no memory
provider is set, no plugin CLI commands appear in the CLI.
Only one memory provider can be active at a time — at most one set of
plugin CLI commands is registered. Users who haven't configured honcho
(or any memory provider) won't see 'hermes honcho' in their help output.
Adds test for inactive provider returning empty results.
Add ctx.register_cli_command() to PluginContext for general plugins and
discover_plugin_cli_commands() to memory plugin system. Plugins that
provide a register_cli(subparser) function in their cli.py are
automatically discovered during argparse setup and wired into the CLI.
- Remove 95-line hardcoded honcho argparse block from main.py
- Move honcho subcommand tree into plugins/memory/honcho/cli.py
via register_cli() convention
- hermes honcho setup now redirects to hermes memory setup (unified path)
- hermes honcho (no subcommand) shows status instead of running setup
- Future plugins can register CLI commands without touching core files
- PluginManager stores CLI registrations in _cli_commands dict
- Memory plugin discovery scans cli.py for register_cli at argparse time
main.py: -102 lines of hardcoded plugin routing
As the agent navigates into subdirectories via tool calls (read_file,
terminal, search_files, etc.), automatically discover and load project
context files (AGENTS.md, CLAUDE.md, .cursorrules) from those directories.
Previously, context files were only loaded from the CWD at session start.
If the agent moved into backend/, frontend/, or any subdirectory with its
own AGENTS.md, those instructions were never seen.
Now, SubdirectoryHintTracker watches tool call arguments for file paths
and shell commands, resolves directories, and loads hint files on first
access. Discovered hints are appended to the tool result so the model
gets relevant context at the moment it starts working in a new area —
without modifying the system prompt (preserving prompt caching).
Features:
- Extracts paths from tool args (path, workdir) and shell commands
- Loads AGENTS.md, CLAUDE.md, .cursorrules (first match per directory)
- Deduplicates — each directory loaded at most once per session
- Ignores paths outside the working directory
- Truncates large hint files at 8K chars
- Works on both sequential and concurrent tool execution paths
Inspired by Block/goose SubdirectoryHintTracker.
Plain functions imported as class attributes in APIServerAdapter get
auto-bound as methods via Python's descriptor protocol. Every
self._cron_*() call injected self as the first positional argument,
causing TypeError on all 8 cron API endpoints at runtime.
Wrap each import with staticmethod() so self._cron_*() calls dispatch
correctly without modifying any call sites.

Add POST /v1/runs to start async agent runs and GET /v1/runs/{run_id}/events
for SSE streaming of typed lifecycle events (tool.started, tool.completed,
message.delta, reasoning.available, run.completed, run.failed).
Changes the internal tool_progress_callback signature from positional
(tool_name, preview, args) to event-type-first
(event_type, tool_name, preview, args, **kwargs). Existing consumers
filter on event_type and remain backward-compatible.
Adds concurrency limit (_MAX_CONCURRENT_RUNS=10) and orphaned run sweep.
Fixes logic inversion in cli.py _on_tool_progress where the original PR
would have displayed internal tools instead of non-internal ones.

Removing an env-seeded credential (e.g. from OPENROUTER_API_KEY) via
'hermes auth' previously had no lasting effect -- the entry was deleted
from auth.json but load_pool() re-created it on the next call because
the env var was still set.
Now auth_remove_command detects env-sourced entries (source starts with
'env:') and calls the new remove_env_value() to strip the var from both
.env and os.environ, preventing re-seeding.
Changes:
- hermes_cli/config.py: add remove_env_value() -- atomically removes a
line from .env and pops from os.environ
- hermes_cli/auth_commands.py: auth_remove_command clears env var when
removing an env-seeded pool entry
- 8 new tests covering remove_env_value and the full zombie-credential
lifecycle (remove -> reload -> stays gone)
Previously, typing a /command that isn't a built-in, plugin, or skill
would silently fall through to the LLM as plain text. The model often
interprets it as a loose instruction and invents unrelated tool calls —
e.g. a stray /claude_code slipped through and the model fabricated a
delegate_task invocation that got stuck in an OAuth loop.
Now we check GATEWAY_KNOWN_COMMANDS after the skill / plugin /
unavailable-skill lookups and return an actionable message pointing the
user at /commands. The user gets feedback, and the agent doesn't waste
a round-trip guessing what /foo-bar was supposed to mean.
Telegram's Bot API disallows hyphens in command names, so
_build_telegram_menu registers /claude-code as /claude_code. When the
user taps it from autocomplete, the gateway dispatch did a direct
lookup against skill_cmds (keyed on the hyphenated form) and missed,
silently falling through to the LLM as plain text. The model would
then typically call delegate_task, spawning a Hermes subagent instead
of invoking the intended skill.
Normalize underscores to hyphens in skill and plugin command lookup,
matching the existing pattern in _check_unavailable_skill.
Telegram polling can inherit a stale webhook registration when a deployment
switches transport modes, which leaves getUpdates idle even though the gateway
starts cleanly. Outbound send also treats Telegram retry_after responses as
terminal errors, so brief flood control can drop tool progress and replies.
Constraint: Keep the PR narrowly scoped to upstream/main Telegram adapter behavior
Rejected: Port OpenClaw's broader polling supervisor and offset persistence | too broad for an isolated fix PR
Confidence: high
Scope-risk: narrow
Reversibility: clean
Directive: Polling mode should clear webhook state before starting getUpdates, and send-path retry logic must distinguish flood control from timeouts
Tested: uv run --extra dev pytest tests/gateway/test_telegram_* -q
Not-tested: Live Telegram webhook-to-polling migration and real Bot API 429 behavior
Replace the two-step stop/start restart with a single
launchctl kickstart -k call. When the gateway triggers a
restart from inside its own process tree, the old stop
command kills the shell before the start half is reached.
kickstart -k lets launchd handle the kill+restart atomically.
launchctl load/unload/start/stop are deprecated on macOS since 10.10
and fail silently on modern versions. This replaces them with the
current equivalents:
- load -> bootstrap gui/<uid> <plist>
- unload -> bootout gui/<uid>/<label>
- start -> kickstart gui/<uid>/<label>
- stop -> kill SIGTERM gui/<uid>/<label>
Adds _launchd_domain() helper returning the gui/<uid> target domain.
Updates test assertions to match the new command signatures.
Fixes#4820
When an agent was actively processing a message, /status sent via Telegram
(or any gateway) was queued as a pending interrupt instead of being dispatched
immediately. The base platform adapter's handle_message() only had special-case
bypass logic for /approve and /deny, so /status fell through to the default
interrupt path and was never processed as a system command.
Apply the same bypass pattern used by /approve//deny: detect cmd == 'status'
inside the active-session guard, dispatch directly to the message handler, and
send the response without touching session lifecycle or interrupt state.
Adds a regression test that verifies /status is dispatched and responded to
immediately even when _active_sessions contains an entry for the session.
The _session_expiry_watcher retried failed memory flushes forever
because exceptions were caught at debug level without setting
memory_flushed=True. Expired sessions with transient failures
(rate limits, network errors) would retry every 5 minutes
indefinitely, burning API quota and blocking gateway message
processing via 429 rate limit cascades.
Observed case: a March 19 session retried 28+ times over ~17 days,
causing repeated 429 errors that made Telegram unresponsive.
Add a per-session failure counter (_flush_failures) that gives up
after 3 consecutive attempts and marks the session as flushed to
break the loop.
The API server platform never passed fallback_model to AIAgent(),
so the fallback provider chain was always empty for requests through
the OpenAI-compatible endpoint. Load it via GatewayApp._load_fallback_model()
to match the behavior of Telegram/Discord/Slack platforms.
MCP server names (e.g. annas, libgen) are added to enabled_toolsets by
_get_platform_tools() but aren't registered in TOOLSETS until later when
_sync_mcp_toolsets() runs during tool discovery. The validation in
HermesCLI.__init__() fires before that, producing a false warning.
Fix: exclude configured MCP server names from the validation check.
CLI_CONFIG is already available at the call site, so no new imports needed.
Closes#5267 (alternative fix)
* feat: coerce tool call arguments to match JSON Schema types
LLMs frequently return numbers as strings ("42" instead of 42) and
booleans as strings ("true" instead of true). This causes silent
failures with MCP tools and any tool with strictly-typed parameters.
Added coerce_tool_args() in model_tools.py that runs before every tool
dispatch. For each argument, it checks the tool registry schema and
attempts safe coercion:
- "42" → 42 when schema says "type": "integer"
- "3.14" → 3.14 when schema says "type": "number"
- "true"/"false" → True/False when schema says "type": "boolean"
- Union types tried in order
- Original values preserved when coercion fails or is not applicable
Inspired by Block/goose tool argument coercion system.
* fix: accept reasoning-only responses without retries — set content to "(empty)"
Previously, when a model returned reasoning/thinking but no visible
content, we entered a 120-line retry/classify/compress/salvage cascade
that wasted 3+ API calls trying to "fix" the response. The model was
done thinking — retrying with the same input just burned money.
Now reasoning-only responses are accepted immediately:
- Reasoning stays in the `reasoning` field (semantically correct)
- Content set to "(empty)" — valid non-empty string every provider accepts
- No retries, no compression triggers, no salvage logic
- Session history contains "(empty)" not "" — prevents #2128 session
poisoning where empty assistant content caused prefill rejections
Removes ~120 lines, adds ~15. Saves 2-3 API calls per reasoning-only
response. Fixes#2128.

Three improvements to Matrix cron delivery:
1. Live adapter path: when the gateway is running, cron delivery now uses
the connected MatrixAdapter via run_coroutine_threadsafe instead of
the standalone HTTP PUT. This enables delivery to E2EE rooms where
the raw HTTP path cannot encrypt. Falls back to standalone on failure.
Threads adapters + event loop from gateway -> cron ticker -> tick() ->
_deliver_result(). (from #3767)
2. HTML formatted_body: _send_matrix() now converts markdown to HTML
using the optional markdown library, with h1-h6 to bold conversion
for Element X compatibility. Falls back to plain text if markdown
is not installed. Also adds random bytes to txn_id to prevent
collisions. (from #5236)
3. Origin fallback: when deliver="origin" but origin is null (jobs
created via API/scripts), falls back to HOME_CHANNEL env vars
in order: matrix -> telegram -> discord -> slack. (from #2641)

Users hitting the 10-minute default during complex tool chains.
Bumps both the execution cap and stale-lock eviction timeout.
Still overridable via HERMES_AGENT_TIMEOUT env var (0 = unlimited).
Previously, tool results exceeding 100K characters were silently chopped
with only a '[Truncated]' notice — the rest of the content was lost
permanently. The model had no way to access the truncated portion.
Now, oversized results are written to HERMES_HOME/cache/tool_responses/
and the model receives:
- A 1,500-char head preview for immediate context
- The file path so it can use read_file/search_files on the full output
This preserves the context window protection (inline content stays small)
while making the full data recoverable. Falls back to the old destructive
truncation if the file write fails.
Inspired by Block/goose's large response handler pattern.
