## What it does

The skill turns the agent into a Magento 2 performance analyst. It covers the whole loop: profile code, database and network, locate the bottlenecks, then build an optimization plan with priorities and a rollback path. Metrics get their own sections — page load time, TTFB, LCP, FID, CLS on the frontend, query execution time, slow query count and cache hit rate on the database side.

Work is split into frontend, database and application. Frontend means Core Web Vitals, trimming JavaScript and CSS, modern image formats. Database means killing N+1 queries, index design, connection pooling, query result caching. Application means PHP execution, memory leaks, caching strategy, lazy loading. Named tools include Blackfire, XHProf, New Relic and browser DevTools.

Measure before you change anything — that is the skill's own rule, and without a baseline every edit is a guess. Profiling needs developer mode: `bin/magento deploy:mode:set developer`. On a live store that switch is worth testing under load first.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add maxnorm/magento2-agent-skills --skill magento-performance-analyst -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add maxnorm/magento2-agent-skills --skill magento-performance-analyst -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add maxnorm/magento2-agent-skills --skill magento-performance-analyst -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install maxnorm/magento2-agent-skills magento-performance-analyst
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add maxnorm/magento2-agent-skills --skill magento-performance-analyst -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/maxnorm/magento2-agent-skills --path skills/magento-performance-analyst
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add maxnorm/magento2-agent-skills --skill magento-performance-analyst -a opencode
```

### Claude.ai

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

## When to use it
- find the bottleneck behind a slow Magento 2 page
- read slow SQL queries and remove N+1 patterns
- capture baseline metrics before touching code
- build a prioritized optimization plan with rollback
- check the frontend against Core Web Vitals

## Example prompts
- profile this Magento 2 catalog and show where the time goes
- find the slow queries on the product page
- draft an optimization plan ordered by impact
