| # Auto-approves a PR when a trusted review bot posts an LGTM verdict. | |
| # | |
| # Two review bots are trusted, and neither can submit an APPROVE review | |
| # itself (GitHub rejects self/app approvals for those integrations), so each | |
| # posts a COMMENT-state review whose body starts with an "LGTM" verdict. | |
| # This workflow turns that signal into a real approval from | |
| # github-actions[bot]. | |
| # | |
| # * claude[bot] — Claude Code's review sessions (verdict | |
| # contract in REVIEW.md) | |
| # * coreplane-switchboard[bot] — Switchboard's `review` agent | |
| # (github.com/coreplanelabs/switchboard). | |
| # Its "LGTM" line is written by the bot | |
| # process from a structured verdict, never by | |
| # the model's prose (fail-closed: no verdict | |
| # → not approving). | |
| # | |
| # Inert until a repo admin enables "Allow GitHub Actions to create and | |
| # approve pull requests" under Settings -> Actions -> General; without | |
| # that setting the approval POST fails with 422. | |
| # | |
| # Guards: | |
| # * Only fires for reviews authored by one of the two bots, matched by | |
| # both login and immutable numeric user id, in state "commented", whose | |
| # body starts with "LGTM" (a mention elsewhere in the body never | |
| # fires). | |
| # * Skips if the review is pinned to a commit that is no longer the | |
| # PR head (a push landed after the bot reviewed). | |
| # * The approval itself is pinned to the reviewed commit via | |
| # commit_id, so it cannot silently attach to a newer head. | |
| # | |
| # Known residual risk: pull_request_review runs this workflow from the | |
| # PR's merge ref, so a PR that edits this file runs its edited copy. | |
| # Branch protection ("Dismiss stale approvals" + required human review) | |
| # is the real backstop. | |
