merge-guard

v0.1.2

Post-merge verification tail: diffs merged main against the pre-merge state to catch junk files leaked by squash merges and unintended path changes, checks configurable grep-based business invariants (attribution parameters, forbidden patterns), auto-opens a cleanup PR for leaked junk, and guides an adjacent-behavior regression spot-check. Complements pre-merge review gates.

Included Skills1

Use immediately after merging a PR to the default branch (or when asked to verify a recent merge) — post-merge verification tail that catches junk files leaked by squash merges, unintended file changes, violated business invariants, and self-inflicted regressions adjacent to the touched code. Complements pre-merge review; it does not repeat it.
