dev-skills

Use this skill for a systematic review of another person's GitHub Pull Request. Trigger on "review PR 123", "is this safe to merge", "check this PR's design", "does this break the protocol", or "does this solve the issue". Check the problem, architecture, protocol conformance, root cause, necessity, correctness, security, and project rules. Require the human to confirm the specification, the problem, and the approach before a detailed review. Do NOT use for an uncommitted local diff, a PR description, or a lint check.

Use when the user asks to generate, write, draft, refresh, retitle, or align a GitHub Pull Request title or description for the current branch — including phrasings like "write the PR description", "update the PR", "summarize this branch for review", "match our PR template", or "regenerate the body". Analyzes `git diff` against the base branch (final state, not commit history) so added-then-removed work is omitted and fabrication is avoided. Skip for changelogs, release notes, issue comment summaries, or open-ended code review.
