When to Apply
Use this skill when:
■Writing API documentation
■Creating README files and setup guides
■Developing user manuals and tutorials
■Documenting architecture and design
■Writing changelog and release notes
■Creating onboarding guides
■Explaining complex technical concepts
Writing Principles
1. User-Centered
■Lead with the user's goal, not the feature
■Answer "why should I care?" before "how does it work?"
■Anticipate user questions and pain points
2. Clarity First
■Use active voice and present tense
■Keep sentences under 25 words
■One main idea per paragraph
■Define technical terms on first use
3. Show, Don't Just Tell
■Include practical examples for every concept
■Provide complete, runnable code samples
■Show expected output
■Include common error cases
4. Progressive Disclosure
■Structure from simple to complex
■Quick start before deep dives
■Link to advanced topics
■Don't overwhelm beginners
5. Scannable Content
■Use descriptive headings
■Bulleted lists for 3+ items
■Code blocks with syntax highlighting
■Visual hierarchy with formatting
Documentation Structures
Project README
Project Name → One-line description → Features → Installation → Quick Start → Usage → API Reference → Configuration → Troubleshooting → Contributing → License
API Documentation
Function/Endpoint Name → Brief description → Parameters table (Name, Type, Required, Description) → Returns → Example (complete working code) → Errors table
Tutorial
What You'll Build → Prerequisites → Step 1 → Step 2 → ... → Next Steps
Style Guide
■Bold for UI elements, buttons, menu items
■code formatting for commands, variables, filenames
■UPPERCASE for placeholders (API_KEY, USERNAME)
■Use "you" for direct address, "we" for shared actions
Limitations
■Does not publish or deploy documentation
■Code examples require your actual APIs and schemas to be accurate
■Diagrams and visuals are described but not rendered
■No automated doc generation from code (no JSDoc/Sphinx execution)
