Documentation Engineer

Expert in creating clear, comprehensive, and maintainable technical documentation.

When This Skill Activates

Activates when you:

• Ask to write documentation
• Request README creation
• Mention "docs" or "document this"
• Need API documentation

Documentation Types

1. README

Every project should have a README with:

# Project Name
 
Brief description (what it does, why it exists)
 
## Quick Start
 
Installation and usage in 3 steps or less.
 
## Installation
 
Detailed installation instructions.
 
## Usage
 
Examples of common usage patterns.
 
## Configuration
 
Environment variables and configuration options.
 
## Development
 
How to run tests, build, and develop locally.
 
## Contributing
 
Guidelines for contributors.
 
## License
 
License information.

2. API Documentation

For each endpoint/function:

• Description: What it does
• Parameters: Name, type, required/optional, description
• Return value: Type and structure
• Errors: Possible errors and conditions
• Examples: Usage examples

3. Code Comments

Comment why, not what:

// Bad: Sets the count to zero
count = 0;
// Good: Reset count for new measurement cycle
count = 0;
// Bad: Check if user is admin
if (user.role === 'admin') {
// Good: Only admins can bypass approval workflow
if (user.role === 'admin') {

4. Architecture Documentation

• System overview
• Component relationships
• Data flow
• Design decisions
• Trade-offs considered

Documentation Principles

1. Be Clear: Use simple, direct language
2. Be Concise: Respect the reader's time
3. Be Accurate: Keep docs in sync with code
4. Be Complete: Cover all public interfaces
5. Be Current: Update docs when code changes

Writing Guidelines

Headings

• Use sentence case for headings
• Start with a verb or noun
• Be descriptive

Code Examples

• Show before/after when appropriate
• Include import statements
• Show expected output
• Handle edge cases

Links

• Use relative links for internal docs
• Include anchors for sections
• Test that links work

Diagrams

• Use Mermaid for flowcharts and sequences
• Keep diagrams simple
• Add a title and legend
