Moves platform STT out into a plugin that owns the whole whisper.cpp contract: sidecar, config (a JSON file under DATA_PATH/transcribe/, validated against the server before storing), a thin proxy router, a skill so an agent knows the contract without being told, and a script-mode file-browser task (not agentic — no model turn per audio file). sidecar/transcribe.ts and its test moved unchanged from src/servers/api/stt/ — every constant in it has a reason attached and none of it was touched. The platform-side removal (routes, dead useAudioRecording path, Settings screen, locale keys) lands in a separate, uncommitted change in the platform repo for review. Not yet reachable from the file browser: the platform does not load tasks from a plugin's directory yet (skills/affordances/notifications do). Ships anyway per instructions.

Transcribe
Officer's speech-to-text, talking to a self-hosted whisper.cpp server.
Transcribe does not run Whisper and ships no model. You point it at a whisper.cpp /inference server
you already run and it forwards to it, tuned for one person talking into a phone: detect the spoken
language, then transcribe faithfully in it — never translated, never guessed at in English when the
audio is not.
What you get
POST /api/transcribe/transcribe— send an audio file, get back its text and the language Whisper detected. Two-pass under the hood (detect, then transcribe in that language) so a low-confidence guess never quietly defaults to English.- A file-browser task. Right-click an
.mp3,.wavor.m4aand transcribe it without a model turn — the task is a plain script that calls this plugin's own route and files the result next to the original. - A skill, so an agent asked to transcribe something knows the route, the shape, and what to say when nothing is configured, without being told.
What you need
A whisper.cpp server you already run, reachable from this machine, answering POST /inference —
the same container the platform used to talk to directly. Nothing else. No system packages, no host
binaries; the sidecar reaches it with fetch.
Setup
PUT /api/transcribe/config
{ "url": "http://192.168.1.50:64201" }
Validated against the server before it is stored — a wrong URL is a 400 with the reason, not a saved value that fails on the first real transcription.
What this plugin deliberately does not have
- No dashboard route, no dock tile. There is nothing to look at — this is reached through the file
browser's task menu and by an agent that has read the skill, not through a screen. Shipping no
web/is a supported shape, not an oversight. - No streaming. One file in, one answer back. If you want a live microphone, that is a different feature built on top of this one, not something this plugin does today.
- No translation. It transcribes in whatever language was spoken. Whisper's own translate mode is English-only, so honouring "translate into <language>" for anything else would mean silently handing back a rough English rendering of, say, Portuguese audio — worse than refusing.
