## Workflow Overview

This workflow follows a structured, phase-based approach with validation gates to ensure comprehensive documentation review:

1. **Phase 1: Discovery and Inventory** - Map documentation landscape
2. **Phase 2: Quality Assessment** - Evaluate against standards
3. **Phase 3: Gap Analysis** - Identify missing or outdated content
4. **Phase 4: Improvement Planning** - Create prioritized recommendations
5. **Phase 5: Implementation Support** - Guide execution of improvements

**BLOCKING VERIFICATION**: Complete each phase checklist before proceeding to the next phase.

## Phase 1: Discovery and Inventory

**Objective:** Understand the current documentation state and create a comprehensive inventory.

### PHASE 1 CHECKLIST

[ ] **Step 1**: Identify all documentation files in the codebase

- Search for common documentation patterns: `README.md`, `*.md`, `docs/`, `documentation/`
- Identify API documentation files (OpenAPI specs, JSDoc, Sphinx, etc.)
- Locate inline code documentation (comments, docstrings, annotations)
- Find configuration documentation (examples, templates, guides)

[ ] **Step 2**: Categorize documentation by type and purpose

- **User-facing**: README, getting started guides, tutorials
- **API documentation**: Endpoint references, request/response examples
- **Developer guides**: Architecture docs, contribution guidelines, development setup
- **Inline documentation**: Code comments, function docstrings, type annotations
- **Configuration**: Environment setup, deployment guides, troubleshooting

[ ] **Step 3**: Map documentation structure and organization

- Document file organization patterns (`/docs`, `/documentation`, root-level)
- Identify navigation structures (tables of contents, cross-references)
- Note documentation tooling (static site generators, markdown processors)
- Record version control practices (documentation in same repo as code)

[ ] **Step 4**: Identify documentation dependencies and integrations

- External documentation links (API references, third-party docs)
- Automated documentation generation tools (Doxygen, Sphinx, JSDoc)
- CI/CD documentation checks (link validators, markdown linters)
- Documentation hosting platforms (GitHub Pages, ReadTheDocs, custom sites)

**BLOCKING VERIFICATION**: Confirm complete documentation inventory before proceeding to Phase 2.
