SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

Explains how a subsystem works by exploring code and producing a clear architectural explanation. Optionally critique the architecture for issues.

Core Features & Use Cases

Explain Mode (default): generates a concise architectural overview for a subsystem by tracing code paths and identifying key components.
Critique Mode: after the explanation, runs architectural critics to surface design weaknesses and improvement opportunities.
Structured Output: delivers Overview, Key Concepts, How It Works, Where Things Live, Gotchas.
Reference-first Discovery: uses frontmatter 'name' and 'description' for discovery and 'references/' prompts/reports to guide exploration.
Diagram Support: can include mermaid diagrams to visualize flows when helpful.

Quick Start

Ask a question about how a subsystem works and let the Skill generate a senior-engineering architectural explanation.

FAQPage Schema

How do I get an architectural overview of an unfamiliar codebase subsystem?▼

To get an architectural overview of a codebase subsystem, the Skill traces code paths and identifies key components to generate a concise explanation. It delivers a structured breakdown including an overview, key concepts, and data flows.

How can I identify architectural issues and design weaknesses during codebase exploration?▼

You can identify architectural issues during codebase exploration by using Critique Mode. After generating an architectural explanation, it runs architectural critics to surface design weaknesses and improvement opportunities.

Can I generate visual diagrams to visualize codebase data flows and architecture?▼

Yes, you can generate visual diagrams to visualize codebase data flows. The Skill includes diagram support and can automatically generate mermaid diagrams to visualize architectural flows when helpful.

What is the best way to explain how complex software architecture works to a new team?▼

The best way to explain how complex software architecture works is to produce a structured architectural summary. The Skill generates output covering Overview, Key Concepts, How It Works, Where Things Live, and Gotchas for clear team alignment.

Does the codebase analysis require specific dependencies or external tools to map architecture?▼

No specific dependencies or external tools are required to map architecture. The Skill uses reference-first discovery with internal frontmatter and references to guide exploration and produce the architectural explanation.
