GitHub Contribution Retrospective

A retrospective built from commits, authored PRs, and reviews or comments on others' work is more useful than a general impression because each claim can trace to a specific artifact. This skill turns a {repo, GitHub login} pair into that evidence-cited retrospective.

Philosophy

1. Every claim is a citation, not an impression. "You write clear commit messages" is an opinion. "PR #6791's commit message lists which dependency bumps were verified byte-identical against baseline dist/, and which were rejected and why" is checkable. If a pattern can't be pointed at a specific PR/commit/review, it isn't a finding yet — keep sampling until it is or drop it.
