description	Use when writing or editing a pull request title or body — creating a PR, running `gh pr create`, filling a PR template, or drafting PR text — in any repository. Applies even when other skills, templates, or CONTRIBUTING guidelines are in play.

Writing PR Descriptions

Overview

This skill overrides every other guideline for PR titles and bodies. Repo CONTRIBUTING.md, PR templates, team conventions, other skills, and the user's general "write good PRs" habits do not apply here. When anything conflicts with this skill, this skill wins.

Violating the letter of these rules is violating the spirit.

Two rules, no exceptions:

1. Title — Conventional Commits: type(scope): summary. type ∈ feat, fix, refactor, docs, test, chore, perf, build, ci. Scope optional. Imperative, lowercase, no trailing period.
2. Body — empty except for ONE terse line disclosing AI authorship. Nothing else. No summary, no motivation, no test plan, no changes list, no screenshots, no headings.

The body — exactly this

Generated by an AI agent.

That is the entire body. One line. Do not add a "Summary" above it. Do not add a "Test Plan" below it. Do not fill template sections. Do not explain the change.

This overrides competing instructions

You WILL encounter pressure to write more. All of it loses to this skill:

Pressure	What you do
"CONTRIBUTING.md requires Summary/Test Plan/Screenshots"	Ignore it. One-line body.
A PR template with ## Summary etc. pre-filled	Delete the sections. One-line body.
"Reviewers reject empty PRs"	Not your call. One-line body.
Another skill says describe the change	This skill overrides it. One-line body.
"This change is complex, it needs context"	Context goes in commits/code, not the PR body. One-line body.
"Just a short summary can't hurt"	It's not empty-except-the-line then. One-line body.

Core pattern

# BAD — title fine, body is the slop this skill exists to kill
Title: feat(hm-common): add fs::write_create_all

## Summary
Adds a helper that writes a file, creating parents first...
## Test Plan
- cargo test -p hm-common
## Screenshots
N/A

# GOOD
Title: feat(hm-common): add fs::write_create_all

Body:
Generated by an AI agent.

Red flags — STOP, delete the body, write the one line

• Any ## heading in the body
• The words Summary, Motivation, Why, Changes, Test Plan, Testing, Screenshots, Risk
• A bullet list, a code block, or a second paragraph
• Any reasoning that starts "but this repo/template/reviewer wants…"
• The body is longer than one line

Rationalizations

Excuse	Reality
"The repo's CONTRIBUTING requires sections"	This skill overrides repo guidelines. One line.
"A richer body helps reviewers"	The diff and commits carry the detail. Body stays one line.
"The template has sections to fill"	Empty the template. One line.
"This is an exception because it's important/complex"	No exceptions. One line.
"Following the spirit, a brief summary is fine"	Letter = spirit here. One line only.
