Overview

Two Primary Capabilities

1. Greenfield Documentation: Create professional documentation from templates for new projects
2. Brownfield Documentation: Reverse-engineer documentation from existing codebases

PDA Architecture (54% Token Reduction)

This skill uses Progressive Disclosure Architecture to minimize token consumption while maintaining full functionality:

• Core (Auto-loaded): SKILL.md (~2,500 tokens) - Routing, execution logic, and quick start
• On-demand: Workflow guides, templates, mappings (~10,000 tokens, loaded selectively)

Typical Token Load: 2,500 tokens (just SKILL.md) to 5,000 tokens (with workflow) = 44-72% reduction vs v1.0

Key Features

1. Template-Based Creation (Greenfield)

Create professional documentation from scratch using industry-standard templates:

2. Code-to-Docs Reverse Engineering (Brownfield)

Automatically generate documentation from existing code:

Backend Frameworks:

• Spring Boot (Fully mapped) - Controllers to OpenAPI, Entities to ER diagrams, Services to SDD
• FastAPI, Express.js, Django, Flask (Planned)

Infrastructure:

• Pulumi (Fully mapped) - Resources to deployment docs, architecture diagrams
• Terraform, AWS CDK (Planned)

Frontend:

• React, Next.js, Vue.js (Planned)

Data and CLI:

• Python ETL, Apache Airflow, CLIs (Planned)

3. Documentation Audit and Quality Control

• Automated quality checklists (SRS, PRD, SDD, OpenAPI, User Docs)
• Gap analysis and completeness scoring
• Best practices validation (IEEE, OpenAPI, WCAG)
• Improvement recommendations with examples
• Automated fixes for common issues

4. Multi-Format Output

• Markdown (Primary format, Git-friendly)
• DOCX (Microsoft Word via docx skill)
• PDF (Professional documents via pdf skill)
• Diagrams (Mermaid, PlantUML via skills)

5. Visual Documentation

Mermaid Diagrams (via mermaid-architect skill):

• C4 Model: Context, Container, Component
• Flowcharts and decision trees

PlantUML Diagrams (via plantuml skill):

• UML: Class, Sequence, Activity, State Machine
• ER Diagrams (database schema)
• Deployment diagrams

Quick Start

Example 1: Create a Requirements Document

Create a Software Requirements Specification for a payment processing system

Generates: IEEE-compliant SRS with functional requirements, NFRs, acceptance criteria

Example 2: Document Existing Spring Boot App

Document my Spring Boot application at ~/projects/ecommerce-api

Generates: SDD (arc42), OpenAPI spec, C4 diagram, ER diagram, Component diagram

Example 3: Audit API Documentation

Audit my OpenAPI specification at docs/api/openapi.yaml

Generates: Audit report with quality score, gap analysis, recommendations

Example 4: Convert to Multiple Formats

Convert docs/requirements/billing-srs.md to Word format

Generates: Professionally styled DOCX with TOC, styles, formatting

Example 5: Generate Architecture Diagrams

Create a C4 container diagram for my e-commerce microservices platform

Generates: C4 container diagram showing services, databases, external systems

How It Works (PDA Flow)

User Request Flow

Example: "Create an SRS for a billing system"

1. Auto-Load: SKILL.md classifies intent as CREATE_NEW (2,500 tokens)
2. Selective Load:
   • workflows/greenfield-workflow.md (1,500 tokens)
   • templates/markdown/requirements-srs.md (500 tokens)
3. Execute: Generate customized SRS
4. Total Tokens: 4,500 (vs 9,000 in v1.0) = 50% reduction

Intent Classification

The skill automatically classifies your request into one of eight intents:

Integration with Other Skills

This skill seamlessly integrates with other Claude Code skills:

Auto-invocation: The skill automatically calls these skills when needed, you do not need to invoke them manually.

Documentation Philosophy

This skill follows Docs-as-Code principles:

1. Living Documentation: Update docs in the same commit as code changes
2. Minimum Viable Documentation: Small, fresh, accurate docs over large stale docs
3. The Bonsai Tree Principle: Alive but frequently trimmed
4. Audience-Specific: Different docs for stakeholders, developers, users
5. Git-Friendly: Markdown primary format, version controlled with code

Use Cases

Use Case 1: Starting a New Project (Greenfield)

Scenario: Building a new SaaS product, need documentation from day one.

Commands:

1. Create a PRD for a team collaboration platform with real-time messaging
2. Create an SRS for the billing module (high-risk, compliance-critical)
3. Generate an arc42 architecture document for microservices
4. Create OpenAPI spec for the REST API

Result: Complete documentation suite ready for development kickoff.

Use Case 2: Documenting Legacy Code (Brownfield)

Scenario: Inherited a Spring Boot application with zero documentation.

Command:

Document my Spring Boot application at ~/projects/customer-api

Result:

• Software Design Document (arc42 format, 20+ pages)
• OpenAPI specification (extracted from @RestController classes)
• C4 Container diagram (shows architecture)
• Component diagram (shows layer structure)
• ER diagram (from @Entity classes)
• Sequence diagrams (for key workflows)

Use Case 3: Compliance Audit

Scenario: Company needs formal documentation for SOC 2 compliance.

Commands:

1. Create a formal SRS for our payment processing system
2. Audit the SRS for completeness
3. Convert to Word format with professional styling
4. Generate PDF documentation package

Result: Enterprise-grade, audit-ready documentation.

Use Case 4: API Documentation

Scenario: Need to document API for external developers.

Commands:

1. Extract OpenAPI spec from my FastAPI application at ~/api
2. Audit the OpenAPI spec for best practices
3. Create sequence diagrams for key API workflows
4. Convert to PDF for distribution

Result: Professional API documentation ready for developer portal.

Configuration

Custom Templates

Override default templates:

Use my custom SRS template at templates/my-company-srs.md for this project

The skill will use your template instead of the default.

Framework Mapping

To add support for a new framework:

1. Create mappings/{category}/{framework}-mapping.yaml
2. Define detection patterns, extraction rules
3. Test with real codebase

See mappings/backend/spring-boot-mapping.yaml for a complete example.

Troubleshooting

Issue: Framework not detected

Solution: Verify detection files exist:

# For Spring Boot:
ls pom.xml build.gradle
grep -r "@SpringBootApplication" src/

If detection fails, manually specify:

Document this as a Spring Boot application at [path]

Issue: Generated docs too generic

Solution: Provide more context in your request:

Generic:

Create an SRS for an app

Specific (Better):

Create an SRS for a HIPAA-compliant telemedicine app with video consultations,
prescription management, and EHR integration. Must support 10,000 concurrent users.

Issue: Diagrams not generated

Solution: Ensure required skills are installed:

/skill mermaid-architect
/skill plantuml

Issue: Cannot convert to Word/PDF

Solution: Ensure format conversion skills are installed:

/skill docx
/skill pdf
