Pull Request Description Writer

A pull request is a request for someone's time, and most PRs waste it: a one-line title over a 600-line diff, no why, no pointer to the risky part, no note on what was tested — so the reviewer reverse-engineers the intent from the code, slowly and often wrongly. AI-generated PRs are worse, because the agent rarely explains its reasoning at all. Pull Request Description Writer writes the description from the diff. Give it the changed files and, ideally, the ticket the work addresses, and it produces a reviewer-focused description: a summary that leads with why, the meaningful changes grouped by behavior rather than listed file-by-file, review guidance that points the reviewer to where to start and what's risky (the single biggest time-saver), an honest testing section that includes what was deliberately not covered, and risk, migration, and rollback notes where they apply. It scales the description to the change — a one-line fix gets a summary and a test note, a risky migration gets the full set — and it flags any why it had to infer for the author to confirm rather than inventing a motivation. The download includes three reference files: the PR-description template, a review-guidance checklist, and a worked sample. It writes from the diff and context you provide — it doesn't run the code or verify tests, so testing claims come from what you tell it. Works with Claude Code, Cursor, Codex CLI, Gemini CLI, and any SKILL.md agent.
