## What it does

The skill identifies the test framework used by the current project, then installs or updates the matching TDD Guard reporter. Supported targets include Vitest, Jest, Storybook, pytest, PHPUnit, Go, Rust, RSpec, and Minitest. Reporters store test results in `.claude/tdd-guard/data/test.json` under the project root.

It applies framework-specific changes: a `reporters` entry, the Storybook test hook, a pytest setting, a PHPUnit extension or listener, a Go or Rust test target, or Ruby test configuration. The skill does not alter the test framework, build tools, or unrelated dependencies. When it detects multiple frameworks, it asks which one to configure.

Reporter configuration must use an absolute project path. If an existing setup is mixed with custom logic and cannot be migrated safely, the skill reports the issue instead of guessing or changing that logic.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add nizos/tdd-guard --skill setup -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add nizos/tdd-guard --skill setup -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add nizos/tdd-guard --skill setup -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install nizos/tdd-guard setup
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add nizos/tdd-guard --skill setup -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/nizos/tdd-guard --path plugin/skills/setup
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add nizos/tdd-guard --skill setup -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/nizos/tdd-guard/tree/HEAD/plugin/skills/setup/SKILL.md

## When to use it
- identify the test framework used by a project
- install the matching TDD Guard reporter
- update an existing reporter configuration
- migrate reporter settings to the current specification
- preserve the project root during configuration changes

## Example prompts
- Set up TDD Guard for this project and detect its test framework.
- Check the current TDD Guard setup and update the reporter to the current specification.
- Migrate the existing TDD Guard configuration without changing unrelated test settings.

# TDD Guard Setup

Set up TDD Guard for the current project. Your goal is to:

1. Identify the test framework(s) used in this project
2. Install the matching TDD Guard reporter, or update it if already present
3. Configure the reporter, or migrate an existing configuration to match the current specification

## Reporter packages

## Reporter configuration

All reporters write test results to `.claude/tdd-guard/data/test.json` relative to the project root.

**Vitest** — Add the reporter entry to the `reporters` array with `projectRoot` in the options object.

```typescript
reporters: [
  'default',
  ['tdd-guard-vitest', { projectRoot: '/absolute/path/to/project' }],
]
```

**Jest** — Add reporter entry to the `reporters` array with `projectRoot` option.

```typescript
reporters: [
  'default',
  ['tdd-guard-jest', { projectRoot: '/absolute/path/to/project' }],
]
```

**Storybook** — Construct `StorybookReporter` in `.storybook/test-runner.ts` and wire it into the `postVisit` hook.

```typescript
// .storybook/test-runner.ts
import { StorybookReporter } from 'tdd-guard-storybook'

const reporter = new StorybookReporter({
  projectRoot: '/absolute/path/to/project',
})

module.exports = {
  async postVisit(page, context) {
    await reporter.onStoryResult(context)
  },
}

process.on('exit', () => {
  reporter.onComplete()
})
```

**pytest** — Set `tdd_guard_project_root` in pytest config (`pyproject.toml`, `pytest.ini`, or `setup.cfg`).

```toml
[tool.pytest.ini_options]
tdd_guard_project_root = "/absolute/path/to/project"
```

**PHPUnit** — Add extension (PHPUnit 10+) or listener (PHPUnit 9.x) to `phpunit.xml` with project root path.

```xml
<!-- PHPUnit 10+ -->
<extensions>
    <bootstrap class="TddGuard\PHPUnit\TddGuardExtension">
````
