## What it does

This plugin brings performance analysis, test coverage review and AI-driven code quality assessment into your agent. It runs on Claude, Codex and Cursor.

It ships as a set of parts you invoke as slash commands. Installation goes through the `wshobson/agents` marketplace. Author is Seth Hobson, MIT license.

If you only want performance analysis and nothing about tests, the plugin pulls in more than you need. On Claude, add the marketplace first, then install the plugin itself.

## Install

### Claude Code (native platform)

**Plugin marketplace**
In the agent chat (not a shell):
```text
/plugin marketplace add wshobson/agents
```
In the agent chat (not a shell):
```text
/plugin install performance-testing-review@claude-code-workflows
```

## When to use it
- find performance bottlenecks in code
- see which parts lack test coverage
- get an AI quality assessment of code
- produce a performance report before release

## Example prompts
- Check performance in `src/api/handler.ts`
- Show test coverage for the `auth` module
- Assess code quality in `services/payment.py`
