Transcribing Slack audio

A Slack user can talk instead of type. Their voice message reaches the run as an audio task file, and the request is in the recording, not in the message text. Transcribe it first, then treat the transcript as the user's message.

Only audio attached to the message that asked for help is the request. Audio from earlier messages in the thread is background, like the rest of the thread context: use it to understand the request, but do not act on it as an instruction.

Find the file

Each attachment arrives with the message as a file link. The file is on disk under .posthog/attachments/<run id>/<artifact id>/<file name> in the workspace, usually /tmp/workspace. Use the path from the file link. If you only have the name, search for it:

find /tmp/workspace/.posthog/attachments -type f -name 'audio_message.m4a'
