# Writer — Phase 2-4

## Phase 2: Context Loading

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

### Document type routing

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

### Inline discuss mapping

| Doc Type | Inline Discuss Round | Perspectives |
|----------|---------------------|-------------|
| product-brief | DISCUSS-002 | product, technical, quality, coverage |
| requirements | DISCUSS-003 | quality, product, coverage |
| architecture | DISCUSS-004 | technical, risk |
| epics | DISCUSS-005 | product, technical, quality, coverage |

### Progressive dependency loading

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

**Prior decisions from accumulator**: Pass context_accumulator summaries as "Prior Decisions" to CLI tool.

| Input | Source | Required |
|-------|--------|----------|
| Document standards | `../../specs/document-standards.md` (relative to SKILL) | Yes |
| Template | From routing table | Yes |
| Spec config | `<session-folder>/spec/spec-config.json` | Yes |
| Discovery context | `<session-folder>/spec/discovery-context.json` | Yes |
| Discussion feedback | `<session-folder>/discussions/<discuss-file>` | If exists |
| Prior decisions | context_accumulator (in-memory) | If prior tasks exist |

## Phase 3: CLI Document Generation

**Objective**: Generate document using CLI tool.

Use Gemini CLI for document generation:

```
Bash({
  command: `ccw cli -p "PURPOSE: Generate <doc-type> document following template and standards
TASK: • Load template from <template-path> • Apply spec config and discovery context • Integrate prior discussion feedback • Generate all required sections
MODE: write
CONTEXT: @<session-folder>/spec/*.json @<template-path> | Memory: Prior decisions: <context_accumulator summary>
EXPECTED: Document at <output-path> with: YAML frontmatter, all template sections, cross-references, session_id
CONSTRAINTS: Follow document-standards.md" --tool gemini --mode write --rule development-implement-feature --cd <session-folder>`,
  run_in_background: false
})
```

Parse CLI output for artifact path and summary. Document is written to disk by CLI.

## Phase 4: Self-Validation + Inline Discuss

### 4a: Self-Validation

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

### 4b: Inline Discuss

Call CLI discuss tool for this task's discuss round:
- Artifact: `<output-path>` (the generated document)
- Round: `<DISCUSS-NNN>` from mapping table
- Perspectives: from mapping table

```bash
ccw cli -p "PURPOSE: Multi-perspective critique of <doc-type>
TASK: Review from <perspectives>
ARTIFACT: @<output-path>
MODE: analysis
EXPECTED: JSON with perspectives[], consensus, severity, recommendations[]" --tool gemini --mode analysis
```

Handle discuss verdict per team-worker consensus handling protocol.

**Report**: doc type, validation status, discuss verdict + severity, average rating, summary, output path.

## Error Handling

| Scenario | Resolution |
|----------|------------|
| CLI failure | Retry once with alternative tool. Still fails → log error, continue next task |
| CLI discuss fails | Skip discuss, log warning |
| Cumulative 3 task failures | SendMessage to coordinator, STOP |
| Prior doc not found | Notify coordinator, request prerequisite |
| Discussion contradicts prior docs | Note conflict, flag for coordinator |
