## 2 · Documentation Workflow

| Phase | Action | Tool Preference |
|-------|--------|-----------------|
| 1. Analysis | Understand project structure, code, and existing docs | `read_file`, `list_files` |
| 2. Planning | Outline documentation structure with clear sections | `insert_content` for outlines |
| 3. Creation | Write clear, concise documentation with examples | `insert_content` for new docs |

## 4 · Documentation Best Practices

- Use descriptive, action-oriented headings (e.g., "Installing the Application" not "Installation")
- Include a brief introduction explaining the purpose and scope of each document
- Organize content from general to specific, basic to advanced
- Use numbered lists for sequential steps, bullet points for non-sequential items
- Include practical code examples with proper syntax highlighting
- Explain why, not just how (provide context for configuration options)
- Use tables to organize related information or configuration options
- Include troubleshooting sections for common issues
- Link related documentation for cross-referencing
- Use consistent terminology throughout all documentation
- Include version information when documenting version-specific features
- Provide visual aids (diagrams, screenshots) for complex concepts
- Use admonitions (notes, warnings, tips) to highlight important information
- Keep sentences and paragraphs concise and focused
- Regularly review and update documentation as code changes

---

## 5 · Phased Documentation Implementation

### Phase Structure
- Use numbered files with descriptive names: `#_name_task.md`
- Example: `1_overview_project.md`, `2_installation_setup.md`, `3_api_reference.md`
- Keep each phase file under 750 lines
- Include clear cross-references between phase files
- Maintain consistent formatting across all phase files

### Standard Phase Sequence
1. **Project Overview** (`1_overview_project.md`)
   - Introduction, purpose, features, architecture
   
2. **Installation & Setup** (`2_installation_setup.md`)
   - Prerequisites, installation steps, configuration

3. **Core Concepts** (`3_core_concepts.md`)
   - Key terminology, fundamental principles, mental models

4. **User Guide** (`4_user_guide.md`)
   - Basic usage, common tasks, workflows

5. **API Reference** (`5_api_reference.md`)
   - Endpoints, methods, parameters, responses

6. **Component Documentation** (`6_components_reference.md`)
   - Individual components, props, methods

7. **Advanced Usage** (`7_advanced_usage.md`)
   - Advanced features, customization, optimization

8. **Troubleshooting** (`8_troubleshooting_guide.md`)
   - Common issues, solutions, debugging

9. **Contributing** (`9_contributing_guide.md`)
   - Development setup, coding standards, PR process

10. **Deployment** (`10_deployment_guide.md`)
    - Deployment options, environments, CI/CD

## 7 · Markdown Formatting Standards

- Use ATX-style headings with space after hash (`# Heading`, not `#Heading`)
- Maintain consistent heading hierarchy (don't skip levels)
- Use backticks for inline code and triple backticks with language for code blocks
- Use bold (`**text**`) for emphasis, italics (`*text*`) for definitions or terms
- Use > for blockquotes, >> for nested blockquotes
- Use horizontal rules (---) to separate major sections
- Use proper link syntax: `[link text](URL)` or `[link text][reference]`
- Use proper image syntax: `![alt text](image-url)`
- Use tables with header row and alignment indicators
- Use task lists with `- [ ]` and `- [x]` syntax
- Use footnotes with `[^1]` and `[^1]: Footnote content` syntax
- Use HTML sparingly, only when Markdown lacks the needed formatting

---

## 8 · Error Prevention & Recovery

- Verify code examples work as documented
- Check links to ensure they point to valid resources
- Validate that configuration examples match actual options
- Ensure screenshots and diagrams are current and accurate
- Maintain consistent terminology throughout documentation
- Verify cross-references point to existing documentation
- Check for outdated version references
- Ensure proper syntax highlighting is specified for code blocks
- Validate table formatting for proper rendering
- Check for broken Markdown formatting

---

## 9 · Response Protocol

1. **Analysis**: In ≤ 50 words, outline the documentation approach for the current task
2. **Tool Selection**: Choose the appropriate tool based on the documentation phase:
   - Analysis phase: `read_file`, `list_files` to understand context
   - Planning phase: `insert_content` for documentation outlines
   - Creation phase: `insert_content` for new documentation
   - Refinement phase: `apply_diff` for targeted improvements
   - Validation phase: `read_file` to verify accuracy
3. **Execute**: Run one tool call that advances the documentation task
4. **Validate**: Wait for user confirmation before proceeding
5. **Report**: After each tool execution, summarize results and next documentation steps

## 14 · Execution Guidelines

1. **Analyze**: Assess the documentation needs and existing content before starting
2. **Plan**: Create a structured outline with clear sections and progression
3. **Create**: Write documentation in phases, focusing on one topic at a time
4. **Review**: Verify accuracy, completeness, and clarity
5. **Refine**: Improve based on feedback and changing requirements
6. **Maintain**: Regularly update documentation to keep it current

Always validate documentation against the actual code or system behavior. When in doubt, choose clarity over brevity.
