When to Use This Skill

• Creating feature documentation
• Writing BDD test documentation
• Structuring new documentation files
• Understanding documentation standards
• Following numbered hierarchy patterns

Numbered Hierarchy Pattern

Documentation uses numbered prefixes for ordering:

{NN}-{category}/
├── {NN}-{topic}.md
├── {NN}-{topic}.md
└── {NN}-{topic}/
    ├── {NN}-{subtopic}.md
    └── {NN}-{subtopic}.md

Examples:
01-fundamentals/
├── 01-project-overview.md
├── 02-getting-started.md
└── 03-quick-start.md

04-entities/
├── 01-introduction.md
├── 02-entity-config.md
├── 03-api-endpoints.md
└── 04-entity-types/
    ├── 01-core-entities.md
    └── 02-theme-entities.md

Numbering Rules

1. Categories: Start at 01-, increment by 1
2. Topics within category: Start at 01-, increment by 1
3. New content: Add at the end with next number
4. Renumbering: Only when reorganizing (rare)

File Naming Conventions

Correct:
- 01-project-overview.md
- 02-getting-started.md
- auth-testing-guide.md
- entity-creation-guide.md

Incorrect:
- ProjectOverview.md        # Use kebab-case
- getting_started.md        # Use hyphens, not underscores
- 1-overview.md             # Use two-digit prefix: 01-
- overview.md               # Need category context

### 3. Theme Documentation (contents/themes/{theme}/docs/)

Theme-specific documentation.

```markdown
# [Theme Name] Theme

## Overview

## Configuration
[How to configure the theme]

## Customization
[How to customize]

4. BDD Test Documentation (*.bdd.md)

Behavior-Driven Development documentation for tests.

# BDD: [Feature Name]

**Test File:** `cypress/e2e/uat/[feature].cy.ts`
**Last Updated:** [YYYY-MM-DD]

---

## Feature: [Feature Name]

### Scenario: [Scenario Name]

**Given** [precondition]
**When** [action]
**Then** [expected result]

**Test ID:** `[test-id]`
**Tags:** `@[tag1]`, `@[tag2]`

---

### Scenario: [Another Scenario]

**Given** [precondition]
**When** [action]
**Then** [expected result]
**And** [additional expectation]

---

## Edge Cases

### Scenario: [Edge Case]

**Given** [edge case condition]
**When** [action]
**Then** [expected behavior]

Frontmatter (Optional)

Some documentation files use YAML frontmatter:

---
title: Entity System Overview
description: How the entity system works
category: entities
order: 1
---

# Entity System Overview
[Content...]

Code Example Standards

TypeScript Examples

```typescript
// ✅ CORRECT: Include imports when relevant
import { useAuth } from '@/core/hooks/useAuth'

// ✅ CORRECT: Add comments for complex logic
const { user, isAuthenticated } = useAuth()

// ✅ CORRECT: Show practical usage
if (isAuthenticated) {
  console.log(`Welcome, ${user.name}`)
}

### Bash Examples

```markdown
```bash
# Install dependencies
pnpm install

# Run development server
pnpm dev

# Run tests
pnpm test

### JSON Examples

```markdown
```json
{
  "name": "example",
  "version": "1.0.0",
  "description": "Example configuration"
}

## Documentation Templates

### Feature Documentation Template

```markdown
# [Feature Name]

## Overview
[Brief description of the feature]

## Quick Start
[Fastest way to get started]

## Configuration
[How to configure the feature]

## Usage

### Basic Usage
[Simple example]

### Advanced Usage
[Complex example]

## API Reference

### [Function/Method Name]

| Parameter | Type | Required | Description |
|-----------|------|----------|-------------|
| `param1` | string | Yes | Description |
| `param2` | number | No | Description |

**Returns:** `ReturnType`

**Example:**
```typescript
const result = functionName(param1, param2)

### API Endpoint Documentation

```markdown
## [HTTP Method] [Endpoint Path]

### Description
[What this endpoint does]

### Authentication
- **API Key**: Requires `[scope]` scope
- **Session**: Dashboard access required

### Parameters

| Parameter | Type | Location | Required | Description |
|-----------|------|----------|----------|-------------|
| `id` | string | path | Yes | Resource ID |
| `limit` | number | query | No | Page size (default: 20) |

### Request Example
```bash
curl -X POST https://api.example.com/v1/resource \
  -H "Authorization: Bearer sk_xxx" \
  -H "Content-Type: application/json" \
  -d '{"name": "Example"}'

Response Example

{
  "success": true,
  "data": {
    "id": "resource_123",
    "name": "Example"
  }
}

Error Responses

## Documentation Agent

The `documentation-writer` agent creates documentation:

```typescript
// Only create documentation when explicitly requested
await launchAgent('documentation-writer', {
  feature: 'entity_system',
  includeExamples: true,
  includeApiDocs: true,
  includeTroubleshooting: true
})

NEVER Create Documentation Proactively

// ❌ WRONG - Don't create docs unless requested
// Claude Code should NOT create documentation automatically

// ✅ RIGHT - Only when explicitly requested
if (userRequestsDocumentation) {
  await launchAgent('documentation-writer', { task: 'create_docs' })
}

Documentation Quality Checklist

Before Publishing

• All code examples are tested and working
• Links are valid and accessible
• Screenshots are current (if any)
• Grammar and spelling correct
• Table of contents accurate (for long docs)
• Examples cover common use cases
• Error scenarios documented
• Prerequisites stated
• Related docs linked

Maintenance Schedule

• Daily: Fix reported documentation bugs
• Weekly: Update changed API endpoints
• Monthly: Review and update examples
• Quarterly: Comprehensive documentation audit
• Release: Update all affected documentation

Anti-Patterns

# NEVER: Document obvious code
// ❌ BAD: Set the variable to true
const isActive = true

# NEVER: Include auto-generated files in docs
# core/lib/registries/*.ts - DO NOT DOCUMENT

# NEVER: Create documentation without explicit request
# Only create when user asks

# NEVER: Duplicate information
# Link to authoritative sources instead

# NEVER: Skip code examples
# Always include practical examples

# NEVER: Use outdated screenshots
# Update or remove if outdated

# NEVER: Leave TODO comments in published docs
# TODO: Add example later ❌
