## What it does

This skill inspects the current branch, working tree, and complete diff against the base branch using `git` and GitHub CLI. Instead of generating a commit dump, file checklist, or standard template, it drafts a concise note focused on reviewer needs. It highlights changed behavior, affected surfaces, and actual risks before implementation details.

Titles follow the conventional commit format, using types such as `feat`, `fix`, or `ref`. The skill deliberately drops standard sections like Summary or Test Plan when they add no signal. New pull requests are created directly as drafts with `gh pr create --draft`, while existing PRs are patched via `gh api`.

An authenticated `gh` CLI session is strictly required. Without active GitHub authentication, the skill fails immediately because it cannot detect default branches or update pull requests.

## Requirements
- Works with: GitHub

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/skills --skill pr-writer -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/pr-writer/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/pr-writer/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/skills --skill pr-writer -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/pr-writer/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/skills --skill pr-writer -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/pr-writer/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install getsentry/skills pr-writer
```

2. **Manually: put the files in place**
- File: `.github/skills/pr-writer/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add getsentry/skills --skill pr-writer -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/getsentry/skills --path skills/pr-writer
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/pr-writer/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add getsentry/skills --skill pr-writer -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/getsentry/skills/tree/HEAD/skills/pr-writer/SKILL.md

## When to use it
- draft clear PR descriptions directly from full branch diffs
- generate conventional commit PR titles with accurate scopes
- rewrite existing PR bodies after review feedback without narrating commit history
- create draft pull requests automatically via the GitHub CLI

## Example prompts
- Prepare a draft PR description for this branch
- Update the existing PR title and body to reflect our latest commits
- Write a reviewer-focused PR note highlighting the breaking contract change

# PR Writer

Write the PR body as a cover note for reviewers, not a changelog, template,
validation log, or file-by-file summary.

## Inspect the Change

Requires authenticated `gh`. Inspect the current branch, working tree, PR,
base branch, commits, and full diff:

```bash
git branch --show-current
git status --porcelain
gh pr view --json number,title,body,url,baseRefName,headRefName
gh repo view --json defaultBranchRef
```

If `gh pr view` reports that no PR exists, continue with first-time PR
creation. For an existing PR, use its `baseRefName`; otherwise use the
repository default branch. Set `BASE`, then inspect:

```bash
git log "$BASE"..HEAD --oneline
git diff "$BASE"...HEAD
```

If on `main` or `master`, create a feature branch first. Ensure intended
changes are committed and review the whole branch diff, not only the latest
commit or existing PR text.

## Core Rules

- Describe concrete changed behavior, affected surfaces, and reviewer impact
  before implementation detail.
- Explain motivation, risk, tradeoffs, migration, or review focus only when
  useful.
- Use the smallest structure that makes the change easier to review.
- Replace internal prompt or process terminology with specific behavior.
- When refreshing a PR, rewrite around the current full diff without narrating
  review history.

## Titles

Use `<type>(<scope>): <subject>` or `<type>: <subject>`.

Allowed types: `feat`, `fix`, `ref`, `perf`, `docs`, `test`, `build`,
`ci`, `chore`, `style`, `meta`, `license`, and `revert`.

- Describe the dominant full-branch change with the narrowest accurate type
  and scope.
- Use `!` only when the change breaks an external contract, and explain the
  affected surface in the body.
- Avoid vague subjects such as `update`, `cleanup`, `misc`, `fix stuff`,
  or `address feedback`. Do not add a trailing period.
- Keep an existing title only when it still describes the whole diff.

## Body Shape

Choose the minimum useful shape:

| Change | Include |
|--------|---------|
| Small or obvious | One concise paragraph without headings. |
| Feature, bug fix, or refactor | Changed behavior and effect; add root cause, unchanged behavior, or non-obvious approach when relevant. |
| Contract or breaking change | Affected API, schema, payload, config, permission, storage, or CLI surface; include compatibility and migration guidance. |
| Operational, visual, or workflow change | User/operator effect, measured impact, failure modes, or flow when useful. |
| Broad, generated, or cross-cutting change | Organizing principle, why the breadth is necessary, and where review should start. |

Default:

```markdown
<What changed and what effect it has.>

<Why the approach, risk, migration, or review focus matters, if not obvious.>
```
