## Purpose

Implements test-driven development methodology, generating tests before implementation code and guiding users through red-green-refactor cycles for robust software development.

---

## Domain Alignment

| Aspect | Specification |
|--------|---------------|
| **Primary Use** | Software development workflow |
| **Target Users** | Developers, QA engineers |
| **Integration Points** | Test frameworks, CI/CD pipelines |

---

## Triggers

| Trigger Type | Pattern |
|--------------|---------|
| **Implicit** | "test", "TDD", "coverage" keywords |
| **Explicit** | `@tdd` or `@test` prefix |
| **Contextual** | New feature implementation context |

---

## Input/Output

| Direction | Format | Example |
|-----------|--------|---------|
| **Input** | Feature requirement | "Add user authentication" |
| **Output** | Test suite + implementation | Tests first, then code to pass tests |

---

## Safeguards

| Safeguard | Implementation |
|-----------|----------------|
| **Coverage Target** | Minimum 80% coverage suggested |
| **Test Isolation** | Each test independent and idempotent |
| **Framework Detection** | Auto-detect pytest/jest/mocha |
| **Failure Handling** | Clear failure messages with fixes |
