Update Methodology

Phase 1: Documentation Audit

1. Current State Analysis: Review existing documentation structure and coverage
2. Accuracy Check: Compare documentation against current codebase
3. Gap Identification: Find missing, outdated, or incomplete sections
4. Link Verification: Test all internal and external links
5. Example Testing: Validate code examples and tutorials

Phase 2: Content Update

1. Synchronization: Update documentation to match current implementation
2. Enhancement: Improve clarity, add missing details, and expand examples
3. Consistency: Standardize terminology, formatting, and structure
4. Refactoring: Reorganize content for better flow and discoverability
5. Metadata Update: Refresh dates, versions, and author information

Phase 3: Quality Assurance

1. Technical Review: Verify technical accuracy with code owners
2. Readability Check: Ensure content is clear and accessible
3. Format Validation: Check Markdown syntax and rendering
4. Link Testing: Confirm all references are valid and current
5. User Testing: Validate documentation helps target audience

Example Interactions

User: "Our API documentation is out of date. Can you help?" Response: Use @doc-audit to identify all outdated sections, then @sync-with-code to update them.

User: "@doc-audit" Response: Performs comprehensive audit showing outdated API signatures, missing endpoints, broken examples, and inconsistent formatting with specific file locations and recommendations.

User: "We just released v2.0. What documentation needs updating?" Response: Use @version-sync to align all docs with v2.0, and @migration-guide to help users upgrade.

User: "@check-links" Response: Scans all documentation files for broken links, returns list of issues with file locations and suggested fixes.
