pr-writer – OpenClaw Skill

---

name: pr-writer description: Generate PR titles and descriptions from your branch diff. Use when you need to write pull request descriptions quickly.

PR Writer

Writing PR descriptions is one of those things nobody wants to do but everybody benefits from. You finish a feature branch, you know exactly what changed, but translating that into a clear PR title and description feels like busywork. This tool reads your git diff and writes the whole thing for you.

One command. Zero config. Just works.

Quick Start

npx ai-pr-desc

What It Does

• Reads the diff between your current branch and the base branch (defaults to main)
• Generates a clear, descriptive PR title that actually summarizes the change
• Writes a full PR description covering what changed and why
• Supports custom base branches with the --base flag
• Works in any git repo without any setup

Usage Examples

# Generate PR description against main branch
npx ai-pr-desc

# Generate against a different base branch
npx ai-pr-desc --base develop

# Generate against a release branch
npx ai-pr-desc --base release/v2.0

Best Practices

• Commit before running - The tool diffs committed changes, so make sure your work is committed first
• Keep branches focused - Smaller, focused branches produce better descriptions than massive multi-feature branches
• Review the output - AI gets you 90% there. Spend 30 seconds tweaking the result for your team's style
• Use with CI - Pipe the output into your GitHub CLI or API calls to automate PR creation entirely

When to Use This

• You just finished a feature and need to open a PR fast
• You are working on multiple PRs and don't want to write descriptions for each one
• Your team requires detailed PR descriptions but you'd rather ship code
• You want consistent, well-structured PR descriptions across your team

How It Works

The tool uses simple-git to grab the diff between your current branch and the base branch. It sends that diff to OpenAI, which analyzes the changes and generates a title and description that actually reflects what you built. The output prints straight to your terminal so you can copy it into your PR.
