# pull-request-review

A skill that reviews a pull request or branch diff: checks the change against the issue, hunts correctness and security defects, and returns prioritized comments.

## What it does

The skill gives the agent a fixed order of work. It pulls the diff first — `git_diff` for the working tree, `git_diff_range` against the base branch — and reads all of it before saying anything. Then it opens the linked issue, PR description or commit messages and writes one line about what the change claims to do. Files around the diff get opened too, since a change is only correct in context.

Review order is spelled out: does it do what it says, then correctness (edge cases, error paths, concurrency, ordering, off-by-one, null and empty inputs, resource cleanup, timeouts), then security (injection, path traversal, secrets, permission checks, unsafe deserialization, shell execution with user input), then compatibility (public API, config, storage formats, migrations, older callers), then tests, then maintainability. Where the environment allows, the skill runs tests and lint itself.

Output starts with a one-line verdict: approve, approve with nits, or request changes. Findings follow by severity, each with `file:line`, what is wrong, why it matters and a concrete fix; blocking items are kept apart from optional ones. The agent also states what it did not review. Everything runs through `git` and file reads, so a repository with no commit history gives the diff check nothing to work from.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill pull-request-review -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill pull-request-review -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill pull-request-review -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install autohandai/code-cli pull-request-review
```

2. **Manually: put the files in place**
- File: `.github/skills/pull-request-review/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill pull-request-review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/autohandai/code-cli --path src/skills/builtin/pull-request-review
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill pull-request-review -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/autohandai/code-cli/tree/HEAD/src/skills/builtin/pull-request-review/SKILL.md

## When to use it
- confirm a PR meets the issue requirements instead of drifting in scope
- catch correctness bugs and cite the exact file and line
- run a security pass over the change before merge
- check whether the edit breaks public API or migrations
- sort blocking findings from optional nits

## Example prompts
- Review the current branch against `main` and give me a verdict
- Check this PR: what the issue asks for versus what it changes
- Review my changes and flag security issues with line numbers

# Review the change, not the style guide

A useful review finds the defect that would have shipped and explains it so the
author can fix it in one pass.

## Establish scope

1. Get the diff (`git_diff` for the working tree, `git_diff_range` against the
   base branch). Read the whole diff before commenting on any part.
2. Read the linked issue, PR description, or commit messages. Write one line
   stating what the change claims to do.
3. Open the files around the diff; a change is only correct in context.

## Check in this order

1. **Does it do what it says**: every requirement from the issue is met, no
   silent scope changes, no leftover debug code or TODOs.
2. **Correctness**: edge cases, error paths, concurrency, ordering, off-by-one,
   null and empty inputs, resource cleanup, timeouts.
3. **Security**: injection, path traversal, secrets, permission checks,
   unsafe deserialization, shell execution with user input.
4. **Compatibility**: public API, config, storage formats, migrations, feature
   flags, older callers.
5. **Tests**: a test fails before and passes after for each fix; new behavior
   has coverage including edge cases; flaky patterns (sleeps, real network).
6. **Maintainability**: naming, duplication, module boundaries, comments only
   where logic is non-obvious.

Run the tests and lint yourself when the environment allows; a review with
evidence beats one with opinions.

## Deliver

- Verdict first: approve, approve with nits, or request changes, in one line.
- Findings ordered by severity. Each: file:line, what is wrong, why it matters,
  a concrete fix. Mark confidence when you could not verify.
- Separate blocking from optional. Keep nits short or drop them.
- Say what you did not review.
