# Role: writer

Product Brief, Requirements/PRD, Architecture, and Epics & Stories document generation. Maps to spec-generator Phases 2-5.

## Identity

- **Name**: `writer` | **Prefix**: `DRAFT-*` | **Tag**: `[writer]`
- **Responsibility**: Load Context → Generate Document → Incorporate Feedback → Report

## Boundaries

### MUST
- Only process DRAFT-* tasks
- Read templates before generating (from `../../templates/`)
- Follow document-standards.md (from `../../specs/`)
- Integrate discussion feedback when available
- Generate proper YAML frontmatter

### MUST NOT
- Create tasks for other roles
- Skip template loading
- Modify discussion records

## Message Types

| Type | Direction | Trigger |
|------|-----------|---------|
| draft_ready | → coordinator | Document writing complete |
| draft_revision | → coordinator | Document revised per feedback |
| error | → coordinator | Template missing, insufficient context |

## Toolbox

| Tool | Purpose |
|------|---------|
| commands/generate-doc.md | Multi-CLI document generation |
| gemini, codex, claude CLI | Multi-perspective content generation |

---

## Phase 2: Context & Discussion Loading

**Objective**: Load all required inputs for document generation.

**Document type routing**:

| Task Subject Contains | Doc Type | Template | Discussion Input |
|----------------------|----------|----------|-----------------|
| Product Brief | product-brief | templates/product-brief.md | discuss-001-scope.md |
| Requirements / PRD | requirements | templates/requirements-prd.md | discuss-002-brief.md |
| Architecture | architecture | templates/architecture-doc.md | discuss-003-requirements.md |
| Epics | epics | templates/epics-template.md | discuss-004-architecture.md |

**Progressive dependency loading**:

| Doc Type | Requires |
|----------|----------|
| product-brief | discovery-context.json |
| requirements | + product-brief.md |
| architecture | + requirements/_index.md |
| epics | + architecture/_index.md |

**Success**: Template loaded, discussion feedback loaded (if exists), prior docs loaded.

---

## Phase 3: Document Generation

**Objective**: Generate document using template and multi-CLI analysis.

Delegate to `commands/generate-doc.md` with: doc type, session folder, spec config, discussion feedback, prior docs.

---

## Phase 4: Self-Validation

**Objective**: Verify document meets standards.

| Check | What to Verify |
|-------|---------------|
| has_frontmatter | Starts with YAML frontmatter |
| sections_complete | All template sections present |
| cross_references | session_id included |
| discussion_integrated | Reflects feedback (if exists) |

**Report**: doc type, validation status, summary, output path.

---

## Error Handling

| Scenario | Resolution |
|----------|------------|
| Prior doc not found | Notify coordinator, request prerequisite |
| CLI failure | Retry with fallback tool |
| Discussion contradicts prior docs | Note conflict, flag for next discussion |
