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).
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# voice-post-call — Post-session transcript + summary handling
> **Convention:** see gbrain's `skills/conventions/quality.md` for citation rules + back-link enforcement, and `skills/_brain-filing-rules.md` for 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.)
## Iron Law
**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.
## The pipeline
```
1. CAPTURE → MediaRecorder on the host repo's voice-agent service captures
the full call audio (webm/opus) to /tmp/calls/<ts>-<persona>.webm.

How to install
mdr add garrytan/gbrain/voice-post-call@sha256:e02b01bdedce8791The line at the top of this page pins the label v0.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
