# TDD INIT Phase

Start a new TDD cycle and create a Cycle doc.

## Progress Checklist

```
INIT Progress:
- [ ] STATUS確認 → 環境収集 → 既存cycle確認
- [ ] 実装内容確認 → リスク評価 → スコープ確認
- [ ] Cycle doc作成 → tdd-plan自動実行
```

## Restrictions

- No detailed implementation planning (done in PLAN)
- No test code (done in RED)
- No implementation code (done in GREEN)

## Workflow

### Step 1: Check Project Status

```bash
cat docs/STATUS.md 2>/dev/null
```

If not found, recommend `tdd-onboard`. Also check hooks: [reference.md](reference.md#hooks-check)

### Step 2: Collect Environment Info

Collect language versions and key packages for Cycle doc Environment section.
Details: [reference.md](reference.md)

### Step 3: Check Existing Cycles

```bash
ls -t docs/cycles/*.md 2>/dev/null | head -1
```

If an active cycle exists, recommend continuing it.

### Step 4: Ask What to Implement

Ask "What feature do you want to implement?" e.g., login, CSV export.

### Step 4.5: Risk Score Assessment

Calculate risk score (0-100) from user input:

| Score | Result | Action |
|-------|--------|--------|
| 0-29 | PASS | Show confirmation, auto-proceed |
| 30-59 | WARN | Quick questions (Step 4.6), then Step 5 |
| 60-100 | BLOCK | Brainstorm & risk questions (Step 4.7) |

Keyword scores: [reference.md](reference.md)
Record `Risk: [score] ([result])` in Cycle doc.

### Step 4.6: Quick Questions (WARN only)

Ask 2 lightweight questions. Templates: [reference.md](reference.md#warn-questions-30-59)

### Step 4.7: Brainstorm & Risk Questions (BLOCK only)

Templates: [reference.md](reference.md#brainstorm-questions-block-60-1). Bug keywords detected → `Skill(tdd-core:tdd-diagnose)`.

### Step 5: Scope (Layer) Confirmation

Use AskUserQuestion to confirm scope:

| Layer | Description | Plugin |
|-------|-------------|--------|
| Backend | PHP/Python etc. | tdd-php, tdd-python, tdd-flask |
| Frontend | JavaScript/TypeScript | tdd-js, tdd-ts |
| Both | Full stack | Multiple plugins |

Details: [reference.md](reference.md)

### Step 6: Generate Feature Name & Create Cycle Doc

Generate feature name (3-5 words) and create Cycle doc from [templates/cycle.md](templates/cycle.md).

### Step 7: Complete & Auto-Execute Next Phase

Display `INIT Complete` and execute based on `CLAUDE_CODE_EXPERIMENTAL_AGENT_TEAMS`:

| 環境変数 | 実行 |
|----------|------|
| 有効 (`1`) | `Skill(tdd-core:tdd-orchestrate)` |
| 無効 / 未設定 | `Skill(tdd-core:tdd-plan)` |
