## What it does

This skill evaluates newly written code across three distinct layers. First, it benchmarks the work against task specifications or a plan from `/architect`, flagging missed scope and unrequested additions. Next, it verifies system boundaries. It spots architecture drift like direct database queries in UI components, checks naming rules, and flags hardcoded styles that skip design system tokens. Finally, it checks production readiness, including unhandled errors, loading states, and edge cases.

Findings are formatted into a markdown report labeled with Critical, Important, and Minor severity tiers. The skill explicitly refuses to edit files or propose solutions on its own. It stops once the report is rendered, leaving quality decisions and triage entirely in the hands of the developer.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add jsmastery-pro/jsm-agent-skill --skill review -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add jsmastery-pro/jsm-agent-skill --skill review -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add jsmastery-pro/jsm-agent-skill --skill review -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install jsmastery-pro/jsm-agent-skill review
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add jsmastery-pro/jsm-agent-skill --skill review -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/jsmastery-pro/jsm-agent-skill --path skills/review
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add jsmastery-pro/jsm-agent-skill --skill 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/jsmastery-pro/jsm-agent-skill/tree/HEAD/skills/review/SKILL.md

## When to use it
- audit completed code against an `/architect` implementation plan
- catch architecture boundary leaks such as direct database queries in UI components
- flag hardcoded CSS values and colors that bypass the design system
- detect unhandled loading states, empty states, and silent error failures

## Example prompts
- Run the review skill on the newly built checkout feature
- Review my recent profile page changes against the implementation plan
- Audit this branch across all three layers and show the report

description: After building a feature, verify it matches what was planned, respects the system architecture and design standards, and is ready for production. Reports issues clearly so the developer decides what to fix.

Building is not done when the code runs. It is done when the code is correct.

AI moves fast. Fast means things get built that work on the surface but drift from the architecture, violate the design system, or miss edge cases that matter. This skill catches those things before they compound into bigger problems.

Run this after every feature. Before you move on.

## What This Skill Does Not Do

It does not fix anything. It reports what it finds and lets the developer decide what matters and what to do about it. Fixing without understanding is how problems get buried, not solved.

---

## Step 1 — Understand What Should Have Been Built

Before reviewing anything, establish the benchmark.

Read in this order:

- The implementation plan from `/architect` if one exists
- The feature description or task that was given
- Any relevant context files — architecture boundaries, code standards, design rules

If no plan exists, ask the developer to describe what the feature was supposed to do before reviewing. You cannot verify correctness without knowing what correct looks like.

---

## Step 2 — Review in Three Layers

### Layer 1 — Does it match the plan?

Compare what was built against what was planned.

Check:

- Every part of the feature description — is it all there?
- The decisions made during planning — are they reflected in the code?
- The scope — did the implementation stay within bounds or add things that were not asked for?

Flag anything that was planned but missing. Flag anything that was built but not planned.

### Layer 2 — Does it respect the system?

This is where AI drift most commonly happens. The feature works, but it violates rules that the project depends on.

Check:

- **Architecture boundaries** — does code in the right place own the right responsibilities? No UI logic in API routes. No DB calls in components. Whatever the project's boundaries are — are they respected?
- **Design system** — are the correct tokens, classes, and patterns used? Any hardcoded values that should be variables? Any raw color classes that should use the design system?
- **Code standards** — naming conventions, file organisation, TypeScript strictness, error handling patterns — do they match what the project established?
- **Existing patterns** — does this feature introduce a new pattern when an existing one should have been used?

### Layer 3 — Is it production ready?

Check:

- Error handling — what happens when things go wrong? Are errors caught and handled or does the feature silently fail?
- Edge cases — empty states, loading states, missing data — are these handled?
- Console errors — any errors or warnings in the browser or terminal?
```
