google_meet — independently scanned and version-tracked by SaferSkills.
SaferSkills independently audited google_meet (Agent Skill) and scored it 91/100 (green). The audit ran 55 deterministic rules across Security, Supply Chain, Maintenance, Transparency, and Community; it found 1 high-severity and 0 lower-severity findings. The full rule-by-rule trace and per-finding evidence are below. Free, methodology-open.

A fenced bash/python block in SKILL.md carries a natural-language imperative — "now run this", "execute the following command" — directing the agent to execute the fenced content. What looks like documentation becomes an executable payload the agent may run without ever asking you.

The primary manifest — the file an agent reads to learn what this artifact does.
The user says any of:
| Mode | What the bot does |
|---|---|
transcribe (default) | Joins, enables captions, scrapes a transcript. Listen-only. |
realtime | Same as transcribe PLUS speaks into the meeting via OpenAI Realtime. The agent calls meet_say(text) and the bot's voice comes out of the call. |
Pick realtime only when the user actually wants the agent to speak. It costs real money (OpenAI Realtime is pay-per-audio-minute) and requires a virtual audio device set up on the machine running the bot.
| Location | When |
|---|---|
| Local (default) | Gateway machine runs the Playwright bot directly. |
Remote node (node="<name>") | Bot runs on a different machine that has a signed-in Chrome and (for realtime) a configured audio bridge. Useful when the gateway runs on a headless Linux box but the user's real signed-in Chrome lives on their Mac. |
Easiest path — run the built-in installer:
hermes plugins enable google_meet
hermes meet install # pip deps + Chromium (transcribe only)
hermes meet install --realtime # + pulseaudio-utils / brew blackhole+ffmpeg
hermes meet auth # optional; skips guest-lobby wait
hermes meet setup # preflight checkshermes meet install --realtime prompts before running sudo apt-get (Linux) or brew install (macOS). Pass --yes to skip the prompt. It will NOT touch your macOS default-input setting — you have to select BlackHole 2ch in System Settings yourself before starting a realtime meeting.
Or do it manually:
pip install playwright websockets && python -m playwright install chromium
# For realtime mode, additionally:
# Linux: sudo apt install pulseaudio-utils
# macOS: brew install blackhole-2ch ffmpeg
# → System Settings → Sound → Input → BlackHole 2ch
# Then set OPENAI_API_KEY or HERMES_MEET_REALTIME_KEY in ~/.hermes/.envFor a remote node:
# on the user's Mac (where Chrome is signed in):
pip install playwright websockets && python -m playwright install chromium
hermes plugins enable google_meet
hermes meet node run --display-name my-mac # persistent server
# copy the printed token
# on the gateway:
hermes meet node approve my-mac ws://<mac-ip>:18789 <token>
hermes meet node ping my-mac # confirm reachableRun hermes meet setup to preflight local prereqs.
meet_join(url=..., mode=..., node=...). Returns immediately.meet_status() for liveness, meet_transcript(last=20) for recent captions. Don't re-read the whole transcript every turn.meet_say(text="...") queues text for TTS. The speech lags by ~2s. Don't spam it.meet_leave() when done, or set duration="30m" on meet_join for auto-leave.meet_transcript() in full, summarize, and use regular tools to send the recap, file issues, schedule followups.| Tool | Parameters | Use |
|---|---|---|
meet_join | url, mode?, guest_name?, duration?, headed?, node? | Start bot |
meet_status | node? | Liveness + progress |
meet_transcript | last?, node? | Read captions |
meet_leave | node? | Close bot |
meet_say | text, node? | Speak in realtime meeting |
node? on all tools: pass a registered node name (or "auto" for the sole node) to operate a remote bot instead of a local one. Omit for local.

Calling it against a transcribe-mode meeting returns a clear error.response.cancel to OpenAI Realtime. Captions take ~500ms to show up, so the bot will talk over the first second or so of a human interruption.meet_status() returns (subset shown, there are more):
| Key | Meaning |
|---|---|

lobbyWaiting | Clicked "Ask to join", waiting on host. |
joinAttemptedAt / joinedAt | Timestamps for lobby-click and actual admission. |
captioning | Caption observer is installed. |
transcriptLines / lastCaptionAt | Transcript progress. |
realtime / realtimeReady | Realtime mode provisioned / WS connected. |
realtimeDevice | Audio device name the bot is feeding (e.g. hermes_meet_src). |
audioBytesOut / lastAudioOutAt | How much PCM the OpenAI session has produced. |
lastBargeInAt | Timestamp of the most recent response.cancel sent. |
leaveReason | duration_expired, lobby_timeout, denied, page_closed, or null. |
error | Last error (soft — bot may still be running). |
