Spec-Driven Development **flips the script** on traditional software development. For decades, code has been king — specifications were just scaffolding we built and discarded once the "real work" of coding began. Spec-Driven Development changes this: **specifications become executable**, directly generating working implementations rather than just guiding them.

## Task Generation Rules
|
||||
|
||||
**IMPORTANT**: Tests are optional. Only generate test tasks if the user explicitly requested testing or TDD approach in the feature specification.
|
||||
|
||||
**CRITICAL**: Tasks MUST be organized by user story to enable independent implementation and testing.
|
||||
|

**Tests are OPTIONAL**: Only generate test tasks if explicitly requested in the feature specification or if user requests TDD approach.
|
||||
|
||||
### Checklist Format (REQUIRED)
|
||||
|
||||
Every task MUST strictly follow this format:
|
||||
|
||||
```text
|
||||
- [ ] [TaskID] [P?] [Story?] Description with file path
|
||||
```
|
||||
|
||||
**Format Components**:
|
||||
|
||||
1. **Checkbox**: ALWAYS start with `- [ ]` (markdown checkbox)
|
||||
2. **Task ID**: Sequential number (T001, T002, T003...) in execution order
|
||||
3. **[P] marker**: Include ONLY if task is parallelizable (different files, no dependencies on incomplete tasks)
|
||||
4. **[Story] label**: REQUIRED for user story phase tasks only
|
||||
- Format: [US1], [US2], [US3], etc. (maps to user stories from spec.md)
|
||||
- Setup phase: NO story label
|
||||
- Foundational phase: NO story label
|
||||
- User Story phases: MUST have story label
|
||||
- Polish phase: NO story label
|
||||
5. **Description**: Clear action with exact file path
|
||||
|
||||
**Examples**:
|
||||
|
||||
- ✅ CORRECT: `- [ ] T001 Create project structure per implementation plan`
|
||||
- ✅ CORRECT: `- [ ] T005 [P] Implement authentication middleware in src/middleware/auth.py`
|
||||
- ✅ CORRECT: `- [ ] T012 [P] [US1] Create User model in src/models/user.py`
|
||||
- ✅ CORRECT: `- [ ] T014 [US1] Implement UserService in src/services/user_service.py`

||||
- ❌ WRONG: `- [ ] Create User model` (missing ID and Story label)

|

- Map each entity to the user story(ies) that need it
|
||||
- If entity serves multiple stories: Put in earliest story or Setup phase

- Relationships → service layer tasks in appropriate story phase

4. **From Setup/Infrastructure**:
|
||||
- Shared infrastructure → Setup phase (Phase 1)
|
||||
- Foundational/blocking tasks → Foundational phase (Phase 2)
|
||||
- Examples: Database schema setup, authentication framework, core libraries, base configurations
|
||||
- These MUST complete before any user story can be implemented
|
||||
- Story-specific setup → within that story's phase

5. **Ordering**:

- Phase 1: Setup (project initialization)
|
||||
- Phase 2: Foundational (blocking prerequisites - must complete before user stories)
