validate-branch-refs

Find and fix the loose ends a branch leaves behind — references to things it renamed, moved, or removed (paths, links, commands, env vars), plus stale factual claims in docs. The skill compares your branch to its base, fixes the clear-cut cases, and asks you about the ambiguous ones.

Use it when

• You're preparing a branch for merge and want to catch stale references.
• You've done a refactor or rename and want docs and comments brought back in sync.

What it helps solve

• Finds stale docs, comments, links, paths, and command names after a branch changes things.
• Helps clean up rename fallout before review.
• Catches outdated claims that would confuse the next developer.

Use it before merging a refactor, rename, or documentation-heavy branch.
