Documentation Creation Skill

Overview

This skill guides the creation of comprehensive project documentation from scratch by analyzing the project codebase and applying established VilnaCRM documentation patterns. It ensures documentation accurately reflects the actual project implementation.

Use this skill for: Initial documentation creation from scratch Use documentation-sync for: Updating existing documentation when code changes

Context (Input)

• Need to create documentation for a project from scratch
• Want consistent style following VilnaCRM patterns
• Need to ensure documentation accuracy against actual codebase
• Project has no existing comprehensive documentation

Task (Function)

Create comprehensive, accurate project documentation by:

1. Analyzing the project codebase thoroughly
2. Creating documentation using established templates
3. Verifying all references against actual codebase
4. Ensuring consistent style and cross-linking

Success Criteria:

• All documentation files created with consistent structure
• All code references verified against actual project structure
• All directory paths and file mentions exist in codebase
• All links between documentation files work correctly
• Technology stack accurately reflected (no false claims)

Quick Start: Documentation Creation Workflow

Step 1: Analyze Project Structure

Before creating any documentation, thoroughly understand the project:

# Check project structure
ls -la src/

# Identify technology stack
cat composer.json | grep -A5 "require"
cat Dockerfile
cat docker-compose.yml

# Identify bounded contexts
ls -la src/Core/
ls -la src/Shared/
ls -la src/Internal/

# Check for entities
find src -path "*/Entity/*.php"

# Check for commands and handlers
find src -name "*Command.php" | head -20
find src -name "*Handler.php" | head -20

Key items to document:

• Technology stack (PHP version, framework, database, runtime)
• Architecture style (DDD, hexagonal, CQRS)
• Bounded contexts and their purposes
• Main entities and their relationships
• Available commands and testing tools

Step 2: Create Technology Stack Summary

Document the verified technology stack:

# PHP version
grep -i "php:" Dockerfile

# Framework
grep -i "symfony" composer.json

# Database
grep -i "mongo\|postgres" docker-compose.yml

# Available make commands
grep -E "^[a-zA-Z][a-zA-Z0-9_-]*:" Makefile | head -30

Create a technology summary table:

Component	Technology	Version
Language	PHP	X.Y
Runtime	PHP-FPM	-
Framework	Symfony	X.Y
Database	MongoDB	X.Y
Web Server	Caddy	-

Step 3: Create Documentation Files

Create each documentation file following this order:

1. main.md - Project overview and design principles
2. getting-started.md - Installation and quick start
3. design-and-architecture.md - Architectural decisions and patterns
4. developer-guide.md - Code structure and development workflow
5. api-endpoints.md - REST and GraphQL API documentation
6. testing.md - Testing strategy and commands
7. glossary.md - Domain terminology and naming conventions
8. user-guide.md - API usage examples
9. advanced-configuration.md - Environment and configuration
10. performance.md - Benchmarks and optimization
11. security.md - Security measures and practices
12. operational.md - Operational considerations
13. onboarding.md - New contributor guide
14. community-and-support.md - Support channels
15. legal-and-licensing.md - License and dependencies
16. release-notes.md - Release process
17. versioning.md - Versioning policy

Step 4: Write Each Documentation File

For each documentation file:

1. Use the appropriate template from reference/doc-templates.md

2. Fill in project-specific content:

   • Project name and description
   • Entity names from codebase
   • Bounded context names
   • URLs and repository links

3. Verify all references:

   • Directory paths exist
   • Commands exist in Makefile
   • Entity names match codebase

4. Add cross-links to related documentation

Step 5: Verify Accuracy

Run comprehensive verification:

1. Technology Stack Verification:

   # Verify PHP version
   grep -i "php" Dockerfile
   
   # Verify framework
   grep -i "symfony" composer.json
   
   # Verify database
   grep -i "mongo\|postgres" docker-compose.yml
   

2. Directory Structure Verification:

   # Verify all mentioned src directories
   for dir in "Shared" "Core" "Internal"; do
     ls -la src/$dir/ 2>/dev/null || echo "Missing: src/$dir"
   done
   

3. Command Verification:

   # Verify mentioned make commands exist
   for cmd in "unit-tests" "integration-tests" "behat" "infection"; do
     grep -q "^$cmd:" Makefile && echo "Found: $cmd" || echo "Missing: $cmd"
   done
   

4. Link Verification:

   • Check all internal markdown links resolve
   • Verify external links are accurate

Documentation Templates

Overview Document (main.md)

# {Project Name}

Welcome to the **{Project Name}** documentation...

## Design Principles

{List project's core design principles}

## Technology Stack

| Component | Technology | Version |
| --------- | ---------- | ------- |
| Language  | PHP        | X.Y     |
| Framework | Symfony    | X.Y     |
| Database  | MongoDB    | X.Y     |

Getting Started (getting-started.md)

See reference/doc-templates.md for complete templates.

---

Constraints

NEVER

• Include references to non-existent directories or files
• Claim features or technologies the project doesn't use
• Leave placeholder text unreplaced
• Skip verification step after creating documentation
• Document commands that don't exist in Makefile

ALWAYS

• Verify every directory path mentioned exists
• Confirm technology stack matches project reality
• Test command examples work in the project
• Update all cross-references to point to correct files
• Maintain consistent terminology throughout
• Add Table of Contents to longer documents (100+ lines)

---

Verification Checklist

After creating documentation:

Technology Accuracy

• PHP version matches Dockerfile
• Framework version matches composer.json
• Database type matches docker-compose.yml
• Runtime environment correctly described
• No false claims about unused technologies

Structure Accuracy

• All mentioned src/ directories exist
• All bounded context names are correct
• Entity names match actual codebase
• Command and handler names are accurate

Command Accuracy

• All make commands exist in Makefile
• Docker commands work as documented
• Test commands produce expected output

Link Accuracy

• All internal markdown links resolve
• External repository links are correct
• No broken navigation links

Content Consistency

• Project name consistent throughout
• Terminology consistent across documents
• No placeholder text remaining

Common Pitfalls

Technology Mismatch

Problem: Documenting technologies the project doesn't use

Solution:

# Verify before documenting
grep -i "fpm" Dockerfile
cat docker-compose.yml
# Only document what actually exists

Missing Directories

Problem: Documenting directories that don't exist in src/

Solution:

# Verify before documenting
ls -la src/
ls -la src/Core/
# Update to match actual structure

Outdated Commands

Problem: Documenting non-existent make targets

Solution:

# Check actual Makefile
grep -E "^[a-zA-Z][a-zA-Z0-9_-]*:" Makefile

Missing Table of Contents

Problem: Long documents hard to navigate

Solution: Add TOC to documents over 100 lines:

## Table of Contents

- [Section 1](#section-1)
- [Section 2](#section-2)
- [Section 3](#section-3)
