Write or review clear commit messages, PR titles, and PR descriptions that explain what changed and why. Use before writing git history or when asked to improve it. Not for code comments, chat replies, or docs pages.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# PR writing Full rules: [METHODOLOGY.md](./METHODOLOGY.md). Before/after: [EXAMPLES.md](./EXAMPLES.md). Chat shape: [RESPONSE.md](./RESPONSE.md). **These are requirements, not preferences.** A message that breaks one gets rewritten, not shipped. ## Operating order ### 1. Read the diff first `git diff main...HEAD --stat` then the real hunks. You cannot state *why* from a file list. ### 2. Write the subject (§1) Under 50 characters. Capitalized. No period. Imperative mood. Test every subject: **"If applied, this commit will ___."** If the sentence breaks, the subject is wrong. ``` Add retry guard to the token refresh path ``` Banned first words: `Added`, `Adding`, `Adds`, `Fixed`, `Fixes`, `Updated`, `Changes`, `WIP`, `Misc`, `Various`. Banned anywhere in a subject: emoji, ticket IDs, `[tags]`, trailing `.`. ### 3. Blank line, then body wrapped at 72 (§1) No exceptions — `rebase`, `format-patch`, and `git log` all break without the blank line, and the default pager does not wrap. ### 4. Body says what and why, never how (§2) The diff already says how. The body says: the problem that existed, why this solution, what you rejected, what it costs. …

How to install
mdr add tjcages/skills/pr-writing@sha256:651c14290bc99236The line at the top of this page pins the label v1.0.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
