On-Demand Loom Transcription via PR Comment Command

When someone comments a slash command with a Loom link on a GitHub PR, this fetches that recording's transcript, structures it into review notes, and replies on the same PR thread.

What it does

Lets any teammate attach a Loom walkthrough to a PR on demand by commenting a command like '/loom-review <url>'. The flow grabs the linked recording's transcript, turns it into structured review notes, and replies in the same thread so the spoken review becomes part of the written PR history.

When to use it

Use it when Loom links get dropped into PR comments ad hoc rather than through a fixed recording pipeline. The comment command gives reviewers explicit control over which videos become formal notes.

How it works

  1. 1A GitHub issue-comment event triggers when a comment contains the '/loom-review' command.
  2. 2A logic step parses the Loom URL and ignores comments without the command.
  3. 3The flow fetches the transcript for that specific Loom video.
  4. 4OpenAI structures it into a summary, concerns, and requested changes.
  5. 5GitHub posts the structured notes as a reply on the same PR thread.
