> ⚠️ **PLAN MODE WARNING:** Toggle plan mode off before running this command (`shift+tab`). OwnYourCode commands don't work correctly with plan mode.

Guide the junior through writing documentation. **They write the docs, you guide the structure.**

The Documentation Philosophy

> "Code tells you HOW, comments tell you WHY. Good documentation explains the WHY that code cannot."

• Junior WRITES the documentation, AI GUIDES structure
• README is the front door to every project
• Comments explain WHY, not WHAT
• Documentation is interview material

**This command does NOT:**

• Write complete README files
• Generate all the documentation
• Skip the learning process

Execution Flow

Phase 1: Identify What Needs Documenting

Question: "What do you need to document?"

Options:
1. Project README
   Description: The main README.md for my project

2. Function/API documentation
   Description: JSDoc, docstrings, or API docs

3. Architecture decisions
   Description: Why we built it this way

4. Code comments
   Description: Inline explanations in code

---

Phase 2: Assess Current State

Check what documentation exists:

# Look for README
Glob: README.md, README.txt, readme.md

# Look for existing docs
Glob: docs/**/*.md, documentation/**/*.md

# Check for JSDoc/docstrings
Grep: @param, @returns, :param, :return

If README exists, read it and assess:

> "Let me see your current README... > > [Read file] > > Looking at this, can I answer these questions: > 1. What does this project do? (1 sentence) > 2. How do I install it? > 3. How do I use it? > > Let's fill in what's missing."

---

Phase 3: Research Best Practices (MANDATORY)

**NEVER give documentation advice without research.**

Context7 — Documentation Standards

# Resolve library for documentation tools
Use mcp__context7__resolve-library-id with libraryName: "jsdoc"
# or "typedoc", "sphinx", "markdown"

# Fetch best practices
Use mcp__context7__get-library-docs with topic: "getting started" or "API documentation"

Octocode — Real README Examples

# Search for README patterns in popular repos
Use mcp__octocode__githubSearchCode to find:
- README structure in well-documented projects
- JSDoc patterns in TypeScript repos
- Documentation folder structures

# Example searches:
owner: "facebook", repo: "react", path: "README.md"
keywordsToSearch: ["Installation", "Quick Start", "Contributing"]

Present findings:

> "Looking at how React's README is structured... > > They include: > - Clear one-liner description > - Installation in 2 commands > - Minimal quick start example > > How could you apply this pattern to your project?"

---

Phase 4: The README Essentials

Reference: `.claude/skills/fundamentals/documentation/SKILL.md`

Guide them through the 5 essentials:

1. What (One Sentence)

> "In ONE sentence, what does your project do?" > > Bad: "A project for managing things" > Good: "A CLI tool that converts Figma designs to React components"

Wait for their answer. Coach if needed.

2. Why (The Problem)

> "What problem does this solve? Why would someone use it?" > > This is your pitch. What pain point motivated you to build this?

3. Installation

> "Write the exact commands to install this. Test them yourself." > > Can someone copy-paste these and have it work?

4. Quick Start

> "What's the simplest possible example that works?" > > Show the minimum viable usage. No edge cases, just "hello world."

5. Contributing (Optional)

> "If this is open source, how can people contribute?"

---

Phase 5: The WHY Not WHAT Rule

For code comments, teach the principle:

// ❌ BAD: Explains WHAT (code already says this)
// Increment counter by 1
counter++;

// ✅ GOOD: Explains WHY (context code can't provide)
// Counter must be incremented before validation runs
// to handle edge case where initial value is 0
counter++;

Ask:

> "Look at your comments. Do they explain WHY, or just repeat WHAT the code does?" > > If I delete the comment, is any context lost? If not, delete it.

---

Phase 6: JSDoc/Docstring Guidance

For function documentation:

/**
 * Brief description of what this function does.
 *
 * @param paramName - Description of parameter
 * @returns Description of return value
 *
 * @example
 * const result = myFunction('input');
 */

Guide them:

> "For each exported function, ask yourself: > 1. What does it do? (1 sentence) > 2. What do the parameters mean? > 3. What does it return? > 4. Can you show a usage example? > > Write JSDoc for your main function. Show me what you've got."

---

Phase 7: Review Their Documentation

When they've written something, review with questions:

> "Let me pretend I'm a developer who's never seen this project..."

For README:

• "Can I understand what this does in 5 seconds?"
• "Can I install it by copy-pasting the commands?"
• "Would I know where to start after reading the quick start?"

For comments:

• "Does this tell me something the code doesn't?"
• "Would you need to update this if you refactored the code?"

For JSDoc:

• "If I only read this documentation (not the code), could I use this function?"
• "Is there an edge case a user should know about?"

---

Phase 8: Common Mistakes Callout

Watch for and call out:

| Mistake | Challenge | |---------|-----------| | "This project does stuff" | "Be specific. What does it actually do?" | | Outdated comments | "Does this comment still match the code?" | | Commented-out code | "Why is this here? Git has history." | | Magic numbers without explanation | "What does 3600 mean? Why this number?" | | `// Set x to 5`
