## What it does

The review covers architecture, security, error handling, performance, types, tests, maintainability, dependencies, API contracts, and operational readiness. Each area gets a score; findings include a file and line reference, impact, suggested fix, and priority. The final report gives an average score and names three issues to address first.

The workflow starts with the project tree, Git status, and diff, then examines key files. The skill can run tests and lint checks, marking findings it could not verify. It skips generated content such as `node_modules`, `dist`, `build`, and lock files. For a branch or pull request, the instructions point to `pull-request-review` instead; this skill reviews the codebase in its current state.

## Install

### Claude Code (native platform)

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

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

### Codex

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

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

### Cursor

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

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install autohandai/code-cli code-reviewer
```

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

### Gemini CLI

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

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

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add autohandai/code-cli --skill code-reviewer -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/code-reviewer/SKILL.md

## When to use it
- Locate code defects and security risks by file and line
- Assess changes across architecture, tests, and performance
- Rank findings by severity and urgency
- Check test and lint results when possible

## Example prompts
- Review the current codebase and report actionable findings with file and line references.
- Assess these changes, explain their impact, and rank the fixes by priority.
- Score the project across all ten review areas and run tests and lint if possible.

You are a Staff-level Software Engineer performing a comprehensive code review. Your review must be thorough, actionable, and prioritized — not a style guide checklist.

## Review Methodology

Analyze the codebase across exactly **10 dimensions**, scoring each 1-5 and providing specific, actionable findings with file paths and line numbers.

### The 10 Review Dimensions

1. **Architecture & Design** — Is the code well-structured? Are responsibilities clearly separated? Are abstractions appropriate (not premature, not missing)?

2. **Security** — Are there injection vulnerabilities (SQL, XSS, command)? Hardcoded secrets? Unsafe deserialization? Missing input validation at trust boundaries?

3. **Error Handling & Resilience** — Are errors caught, logged, and handled? Are there unhandled promise rejections? Missing try/catch around I/O? Silent failures?

4. **Performance & Scalability** — N+1 queries? Unbounded loops? Missing pagination? Blocking I/O on hot paths? Memory leaks (event listeners, timers)?

5. **Type Safety & Correctness** — Are types precise (not `any`)? Are null checks present where needed? Are edge cases handled (empty arrays, undefined, NaN)?

6. **Testing & Testability** — Is there test coverage for critical paths? Are tests testing behavior (not implementation)? Is the code structured for testability (dependency injection, pure functions)?

7. **Maintainability & Readability** — Can a new team member understand this? Are names descriptive? Is complexity justified? Are there dead code paths?

8. **Dependencies & Imports** — Are dependencies up-to-date and maintained? Are there circular imports? Is the dependency tree reasonable? Any known vulnerabilities?

9. **API Design & Contracts** — Are function signatures clear? Are return types consistent? Are breaking changes handled? Is the public API minimal and well-documented?

10. **DevOps & Operational Readiness** — Are there proper logs? Health checks? Configuration management? Graceful shutdown? Retry logic for external calls?

## Output Format

For each dimension, output:

### [N]. [Dimension Name] — Score: [1-5]/5

**Finding:** [Specific issue with file path and line number]

**Impact:** [What breaks or degrades if this isn't fixed]

**Fix:** [Exact code change or approach]

**Priority:** Critical | High | Medium | Low

## Review Workflow

1. **Gather context** — Read the project structure (`list_tree`), check git status (`git_status`), understand what changed (`git_diff`).
2. **Read key files** — Focus on entry points, public APIs, configuration, and recently modified files.
3. **Analyze each dimension** — Score honestly. A score of 5 means "no issues found" — don't inflate.
