## What it does

review-pr-lite reads pull request metadata and changes through `gh pr view` and `gh pr diff`, then examines the patch itself. It looks for behavioral bugs, edge cases, inadequate tests, and maintainability problems. Its security checks cover injection, authorization mistakes, exposed secrets, and unsafe handling of files, network access, shell commands, or deserialization.

The report includes the PR number and numbered findings ranked by severity: low, mid, high, or critical. More severe issues appear first. Once the code review is complete, the skill checks GitHub Actions and reports the state of every workflow run, including runs still in progress. For failures, it investigates likely causes and suggests possible fixes.

The review runs without subagents and leaves the local branch untouched. When no PR is named, the skill targets the pull request associated with the current branch. The repository must be accessible through `git` and `gh`; the skill reads remote changes instead of checking out the pull request locally.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill review-pr-lite -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill review-pr-lite -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill review-pr-lite -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dyoshikawa/rulesync review-pr-lite
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill review-pr-lite -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dyoshikawa/rulesync --path .rulesync/skills/review-pr-lite
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dyoshikawa/rulesync --skill review-pr-lite -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/dyoshikawa/rulesync/tree/HEAD/.rulesync/skills/review-pr-lite/SKILL.md

## When to use it
- Catch bugs and regressions in pull request changes
- Inspect patches for injection risks and exposed secrets
- Spot missing tests and overlooked edge cases
- Investigate failed GitHub Actions runs
- Rank review findings by severity in one report

## Example prompts
- Review the pull request for the current branch and flag code defects or security risks.
- Review PR 123, rank the findings by severity, and check its GitHub Actions runs.
- Inspect PR 123 without changing my local branch and suggest fixes for failed workflow checks.

name: review-pr-lite
description: >-
  Review a pull request for code quality and security issues without using
  subagents. Use when the user wants a lighter-weight PR review in a single
  skill.
targets:
  - "*"
---

target_pr = the user's request

If target_pr is not provided, use the PR of the current branch.

## Important: Do Not Switch the Local Branch

- Do NOT check out, switch, or otherwise move the local branch (e.g., `git checkout`, `git switch`, `gh pr checkout`).
- To inspect the PR's changes, use `git` and `gh` commands that read remote state without moving the working tree. For example:
  - `gh pr view $target_pr` to read PR metadata and description.
  - `gh pr diff $target_pr` to read the diff.
  - `gh pr view $target_pr --json files` or `gh api` to list changed files.
  - `git fetch origin pull/<PR_NUMBER>/head:refs/remotes/origin/pr-<PR_NUMBER>` and `git diff origin/main...origin/pr-<PR_NUMBER>` if a local read-only ref is needed.

## Step 1: Gather PR Context

Run the following in parallel:

- Get the PR description and metadata via `gh pr view $target_pr` (do not check out the PR locally).
- Get the PR diff via `gh pr diff $target_pr`.
- If needed, inspect changed files individually for deeper context using `gh` / `git` commands (e.g., `gh api`, `git show`) — without switching the local branch.

## Step 2: Review the Changes

Review the PR directly in this skill without calling any subagents.

Focus on both of the following:

1. **Code Review**
   - Bugs or behavioral regressions
   - Incorrect assumptions or edge cases
   - Missing or weak tests
   - Maintainability issues that could cause near-term problems

2. **Security Review**
   - Injection risks
   - Auth/authz mistakes
   - Secrets exposure
   - Unsafe file, network, shell, or deserialization behavior
   - Dependency or configuration changes that could weaken security

## Step 3: Report Findings

Integrate all findings into one review result. Please output the PR number in the result so that the user can easily find the PR.

## Reporting Rules

- Assign a severity level to each finding: low, mid, high, or critical.
- Assign a sequential number to each finding (e.g., #1, #2, #3, ...).
- Present findings first, ordered by severity.
- If no findings are discovered, explicitly state that no findings were found.
- Keep the summary brief and focused on risk and testing gaps.

## Step 4: Check GitHub Actions Workflows

After completing the content review, check the status of the GitHub Actions workflows for $target_pr (for example, using `gh pr checks` or `gh run list`).
```
