What it does
Decides whether a change can merge. Reviews a unified diff you supply against its acceptance criteria and upstream gate results, checks whether the changed tests actually exercise the change, classifies API-contract drift as breaking or not, and scores the maintenance pressure on the files it touches. Provided-data: no repository, network or file-system access.
Example prompts
- Here is the diff and the acceptance criteria — is this merge-ready?
- Do the tests in this diff actually cover what it changed?
- Does this change break any existing API consumer, and what version bump does it force?
