## What it does

One command builds the QA skeleton: `tests/docs/`, `tests/e2e/`, `tests/fixtures/`, CSVs for execution and bug tracking, metric and weekly report templates, plus a master prompt for autonomous runs. Test cases follow the TC-[CATEGORY]-[NUMBER] format with Arrange-Act-Assert steps and priorities from P0 to P4.

Initialization overwrites its own template files, so point it at a fresh destination. The script appends `tests/` to the project root, and `<qa-expert-dir>` resolves from the loaded skill directory rather than the target repo. Metrics come from `scripts/calculate_metrics.py`, which reads the tracking CSV and reports progress, pass rate and quality gate status.

Autonomous execution needs one thing up front: an available, authorized host runner. A prompt alone does not keep a session alive, and after an interruption you have to read back checkpoints and reconcile uncertain side effects before picking the next test. Auditing an already-rendered UI is out of scope here — that is what `frontend-visual-qa` covers.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill qa-expert -a claude-code
```

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

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill qa-expert -a codex
```

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

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill qa-expert -a cursor
```

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install daymade/claude-code-skills qa-expert
```

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

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill qa-expert -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/daymade/claude-code-skills --path qa-expert
```

### Windsurf (Devin Desktop)

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

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add daymade/claude-code-skills --skill qa-expert -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/daymade/claude-code-skills/tree/HEAD/qa-expert/SKILL.md

## When to use it
- scaffold QA directories and templates from scratch
- write AAA test cases with P0–P4 priorities
- track test execution without losing statuses
- file a bug with reproduction steps and severity
- compute pass rate and quality gate status from the CSV

## Example prompts
- initialize a QA project for my repo
- write AAA test cases for the CLI and assign priorities
- calculate metrics from TEST-EXECUTION-TRACKING.csv

  Sets up QA testing processes: test strategies, Google Testing Standards test cases, P0-P4 bug
  tracking, quality metrics, progress reports, autonomous execution via master prompts, and OWASP

  writing test cases, executing test plans, or tracking bugs. Not for auditing an already-rendered

# QA Expert

Set up test cases, execution tracking, bug reports and QA handoffs using AAA test structure and OWASP security categories.

## When to Use This Skill

Trigger this skill when:
- Setting up QA infrastructure for a new or existing project
- Writing standardized test cases (AAA pattern compliance)
- Executing comprehensive test plans with progress tracking
- Implementing security testing (OWASP Top 10)
- Filing bugs with proper severity classification (P0-P4)
- Generating QA reports (daily summaries, weekly progress)
- Calculating quality metrics (pass rate, coverage, gates)
- Preparing QA documentation for third-party team handoffs
- Enabling autonomous LLM-driven test execution

## Quick Start

**One-command initialization**:
```bash
uv run "<qa-expert-dir>/scripts/init_qa_project.py" "<project-name>" "<project-root>"
```

**What gets created**:
- Directory structure (`tests/docs/`, `tests/e2e/`, `tests/fixtures/`)
- Tracking CSVs (`TEST-EXECUTION-TRACKING.csv`, `BUG-TRACKING-TEMPLATE.csv`)
- Documentation templates (`BASELINE-METRICS.md`, `WEEKLY-PROGRESS-REPORT.md`)
- Master QA Prompt for autonomous execution
- README with preparation steps and links to the generated files

The output directory is the project root; the script appends `tests/`. Use a fresh
destination: initialization overwrites its template files. Replace example CSV
rows, write test specifications and bind the project harness before execution.
Resolve `<qa-expert-dir>` from this loaded Skill's directory, not the target project.

**For autonomous execution**: Follow [the master prompt](references/master_qa_prompt.md)
for preparation, bounded execution and interruption recovery. Initialization
creates templates; it does not run tests or install a scheduler.

## Core Capabilities

### 1. QA Project Initialization

Initialize QA directories and templates:

```bash
uv run "<qa-expert-dir>/scripts/init_qa_project.py" "<project-name>" "<project-root>"
```

Creates directory structure, tracking CSVs, documentation templates, and master prompt for autonomous execution.

**Use when**: Starting QA from scratch or migrating to structured QA process.

### 2. Test Case Writing

Write standardized, reproducible test cases following AAA pattern (Arrange-Act-Assert):

1. Read template: `assets/templates/TEST-CASE-TEMPLATE.md`
2. Follow structure: Prerequisites (Arrange) → Test Steps (Act) → Expected Results (Assert)
