voice-post-callPost-call handling for a voice session — turn the transcript into a brain page, post the summary to the operator's messaging surface, archive the audio.
Voice Post Call is an agent skill from garrytan/gbrain. Post-call handling for a voice session — turn the transcript into a brain page, post the summary to the operator's messaging surface, archive the audio. The pipeline is the contract; the firing paths are operator-wired (see "Two firing paths" below for what ships today).
Its SKILL.md is about 1.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file.
The repository describes itself as: Garry's Opinionated OpenClaw/Hermes Agent Brain. The licence is MIT.
Read from SKILL.md and the folder at commit fc54831. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are markdown).
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Voice Post Call loads about 1.7k tokens when it runs. Until then it costs about 72 tokens; SKILL.md has 489 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
ord — whichever is wired in $TARGET_REPO/.env).Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/voice-post-call/SKILL.md (or your agent's skills folder). This skill also uses 1 other file; get the full folder from GitHub.Convention: see gbrain's
skills/conventions/quality.mdfor citation rules + back-link enforcement, andskills/_brain-filing-rules.mdfor the filing decision protocol. (These are not copied by the install; the relative paths resolve only if your host repo mirrors gbrain's skills layout.)
Every call gets processed, even on tool-call failure. The voice persona MAY log mid-session via an opted-in write tool, OR the call may end without that tool firing (model forgot, WebRTC dropped, browser crashed). A call-end handler should post a structured signal regardless so the brain still gets the transcript + audio reference — see "Two firing paths" below for which of these ships today and which the operator implements.
If both paths fire (the tool call AND the call-end handler), the second one is idempotent — it sees the brain page already exists and updates instead of duplicating.
1. CAPTURE → MediaRecorder on the host repo's voice-agent service captures
the full call audio (webm/opus) to /tmp/calls/<ts>-<persona>.webm.
The browser client at /call?test=1 also captures via WebAudio-tee
for E2E asserts; production /call uses server-side capture only.
2. TRANSCRIBE → Whisper (via gbrain transcription) processes the audio. Output:
full transcript (timestamped) + speaker labels where possible.
3. SUMMARIZE → A separate LLM call produces a 3-5 sentence summary covering
key topics, decisions, and unresolved items.
4. WRITE → Create or update meetings/YYYY-MM-DD-call-<persona>.md with:
- frontmatter (date, persona, duration, ratings)
- full transcript in a "Transcript" block-quote section
- summary in a "Summary" section
- audio link (file://, or signed URL if uploaded to storage)
- any entity cross-links (people, companies mentioned)
5. CROSS-LINK → For each entity in the transcript (person, company), append a
timeline entry to people/<slug>.md or companies/<slug>.md pointing
back to this call page. Iron Law: per conventions/quality.md.
6. POST → Send the summary to the operator's messaging surface (Telegram,
Slack, Discord — whichever is wired in $TARGET_REPO/.env).Path A — Persona-initiated mid-call (opt-in):
The voice persona calls log_to_brain via the WebRTC data channel; the host-repo /tool endpoint dispatches through tools.mjs. log_to_brain is in OPTIONAL_OPS, not READ_ONLY_OPS, so this only works if the operator's tools-allowlist.local.json opts in (there is no log_call_summary tool — the override can only enable ops listed in OPTIONAL_OPS).
Path B — Call-end handler (not yet shipped):
The shipped server.mjs has no automatic call-end handler — nothing fires when the WebSocket / WebRTC connection closes. To get the safety-net behavior, implement a post-call handler in your host repo that reads the captured audio + transcript on connection close and runs the pipeline above. Until you do, Path A (opt-in) is the only firing path, and calls where the persona never logs are NOT processed.

SKILL.md names no scripts, command-line tools or credentials: Voice Post Call is instructions for the agent only.
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (mentions a .env file), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Voice Post Call is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.7k tokens (SKILL.md is roughly 6.9k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
