+# Documentation Update & Synchronization
+
+Update project documentation systematically: $ARGUMENTS
+
+## Current Documentation State
+
+- Documentation structure: !`find . -name "*.md" | head -10`
+- Specs directory: @specs/ (if exists)
+- Implementation status: !`grep -r "✅\|❌\|⚠️" docs/ specs/ 2>/dev/null | wc -l` status indicators
+- Recent changes: !`git log --oneline --since="1 week ago" -- "*.md" | head -5`
+- Project progress: @CLAUDE.md or @README.md (if exists)
+
+## Task
+
+## Documentation Analysis
+
+1. Review current documentation status:
+   - Check `specs/implementation_status.md` for overall project status
+   - Review implemented phase document (`specs/phase{N}_implementation_plan.md`)
+   - Review `specs/flutter_structurizr_implementation_spec.md` and `specs/flutter_structurizr_implementation_spec_updated.md`
+   - Review `specs/testing_plan.md` to ensure it is current given recent test passes, failures, and changes
+   - Examine `CLAUDE.md` and `README.md` for project-wide documentation
+   - Check for and document any new lessons learned or best practices in CLAUDE.md
+
+2. Analyze implementation and testing results:
+   - Review what was implemented in the last phase
+   - Review testing results and coverage
+   - Identify new best practices discovered during implementation
+   - Note any implementation challenges and solutions
+   - Cross-reference updated documentation with recent implementation and test results to ensure accuracy
+
+## Documentation Updates
+
+1. Update phase implementation document:
+   - Mark completed tasks with ✅ status
+   - Update implementation percentages
+   - Add detailed notes on implementation approach
+   - Document any deviations from original plan with justification
+   - Add new sections if needed (lessons learned, best practices)
+   - Document specific implementation details for complex components
+   - Include a summary of any new troubleshooting tips or workflow improvements discovered during the phase
+
+2. Update implementation status document:
+   - Update phase completion percentages
+   - Add or update implementation status for components
+   - Add notes on implementation approach and decisions
+   - Document best practices discovered during implementation
+   - Note any challenges overcome and solutions implemented
+
+3. Update implementation specification documents:
+   - Mark completed items with ✅ or strikethrough but preserve original requirements
+   - Add notes on implementation details where appropriate
+   - Add references to implemented files and classes
+   - Update any implementation guidance based on experience
+
+4. Update CLAUDE.md and README.md if necessary:
+   - Add new best practices
+   - Update project status
+   - Add new implementation guidance
+   - Document known issues or limitations
+   - Update usage examples to include new functionality
+
+5. Document new testing procedures:
+   - Add details on test files created
+   - Include test running instructions
+   - Document test coverage
+   - Explain testing approach for complex components
+
+## Documentation Formatting and Structure
+
+1. Maintain consistent documentation style:
+   - Use clear headings and sections
+   - Include code examples where helpful
+   - Use status indicators (✅, ⚠️, ❌) consistently
+   - Maintain proper Markdown formatting
+
+2. Ensure documentation completeness:
+   - Cover all implemented features
+   - Include usage examples
+   - Document API changes or additions
+   - Include troubleshooting guidance for common issues
+
+## Guidelines
+
+- DO NOT CREATE new specification files
+- UPDATE existing files in the `specs/` directory
+- Maintain consistent documentation style
+- Include practical examples where appropriate
+- Cross-reference related documentation sections
+- Document best practices and lessons learned
+- Provide clear status updates on project progress
+- Update numerical completion percentages
+- Ensure documentation reflects actual implementation
+
+Provide a summary of documentation updates after completion, including:
+1. Files updated
+2. Major changes to documentation
+3. Updated completion percentages
+4. New best practices documented
+5. Status of the overall project after this phase
