Phase When to Load File

API Docs Writing API documentation phases/01-api-docs.md

User Guides Creating tutorials phases/02-user-guides.md

README Creating project READMEs phases/03-readme.md

Core Principles

• ONE section per response - Never generate entire docs at once

• Show, don't tell - Include examples

• Clarity first - Simple language, avoid jargon

Quick Reference

Common Section Chunks

Doc Type Chunk Units

README Installation → Quick Start → Usage → API → Contributing

API Docs Overview → Auth → Endpoints (grouped) → Webhooks → Errors

User Guide Getting Started → Features → Tutorials → Troubleshooting

API Endpoint Template

POST /api/users

Creates a new user account.

Authentication

Requires: API Key

Request Body

Response

Success (201):

{ "id": "123", "email": "user@example.com" }

Error Codes

### README Template

```markdown
# Project Name

Brief description.

## Features
- ✅ Feature 1
- ✅ Feature 2

## Installation
```bash
npm install your-package

Quick Start

[code example]

Documentation

- API Reference

## Workflow

1. **Analysis** (< 500 tokens): List sections needed, ask which first
2. **Generate ONE section** (< 800 tokens): Write/Edit file
3. **Report progress**: "X/Y sections complete. Ready for next?"
4. **Repeat**: One section at a time

## Token Budget

- **Analysis**: 300-500 tokens
- **Each section**: 600-800 tokens
- **API groups**: 3-5 endpoints per response

**NEVER exceed 2000 tokens per response!**

## Writing Principles

1. **Clarity**: Simple language
2. **Examples**: Code snippets for everything
3. **Structure**: Clear headings
4. **Completeness**: Cover edge cases
5. **Accuracy**: Keep in sync with code

## LLM-Optimized Documentation Patterns

When generating documentation that will be consumed by LLMs (Claude Code, AI assistants), follow these patterns for maximum efficiency:

### TL;DR Frontmatter (REQUIRED)

Every document MUST include machine-readable frontmatter:

```yaml
---
title: Feature Name
tldr: One-sentence summary for quick LLM context loading
business_value: How this impacts users/revenue/efficiency
complexity: low|medium|high
last_verified: 2025-01-23
stakeholder_relevant: true|false
dependencies:
  - related-feature-1
  - related-module-2
---

Structured Summary Block (REQUIRED)

After the title, include a scannable summary block:

## TL;DR

**What**: [One sentence describing the feature/doc purpose]
**Why**: [Business value or problem solved]
**How**: [Key mechanism or approach in 1-2 sentences]
**Dependencies**: [List related features/components]

Scannable Content Patterns

For LLM efficiency, structure content as:

Pattern
Usage
Example

Tables
Comparisons, options, mappings
Parameters, API endpoints

Bullet Lists
Steps, features, requirements
Installation steps

Code Blocks
Examples, commands, configs
Usage examples

Headers
Section navigation
H2 for main, H3 for sub

Business Context Requirements

Every feature doc should include:

- Business Value Statement (who benefits, how)

- Success Metrics (measurable outcomes)

- Risk/Limitations (what this doesn't do)

Example LLM-Optimized Doc

---
title: User Authentication
tldr: JWT-based auth with OAuth2 support for secure user sessions
business_value: Enables enterprise SSO compliance, reduces login friction
complexity: medium
last_verified: 2025-01-23
stakeholder_relevant: true
dependencies:
  - user-management
  - session-storage
---

# User Authentication

## TL;DR

**What**: JWT-based authentication system with OAuth2 provider support
**Why**: Enables secure user sessions and enterprise SSO compliance
**How**: Issues JWTs on login, validates on each request, supports refresh tokens
**Dependencies**: user-management, session-storage, redis-cache

## Business Value

- Reduces login friction by 60% via social login
- Enables enterprise SSO (required for Fortune 500 clients)
- Improves security posture (SOC2 compliance)

Numbered Docs Folders (Collision Prevention)

When creating numbered documentation folders (e.g., docs/01-platform/
):

BEFORE creating any docs/NN-*
 folder:

# Check for existing numbered prefixes
ls docs/ | grep -E '^[0-9]{2}-' | cut -d'-' -f1 | sort -u

# Detect collisions (duplicates)
ls docs/ | grep -E '^[0-9]{2}-' | cut -d'-' -f1 | sort | uniq -d

Rules:

- Each numeric prefix (01, 02, ..., 98) can only be used ONCE

- 99 is reserved for 99-archive

- Find the next available number before creating

- If collision detected, renumber the new folder

Example:

# Existing: 01-platform, 02-architecture, 04-deployment
# Next available: 03 (gap) or 05 (sequential)
# WRONG: Creating 04-workflows (collision with 04-deployment!)

Image Generation

When documentation needs visuals (diagrams, illustrations, icons), use the /sw:image-generation
 skill:

"Generate a hero image for the authentication documentation"
"Create an architecture diagram illustration for the API docs"
