SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes scripts (resource) and references (resource) components.

What problem does it solve?

This Skill addresses the challenge of quickly understanding large and complex codebases, enabling developers and AI agents to navigate, analyze, and document code efficiently.

Core Features & Use Cases

  • Hierarchical Documentation: Generates documentation at multiple levels (L0-L3) for different audiences.
  • Incremental Scanning: Scans only changed files for faster updates.
  • Semantic Analysis: Extracts business rules, security risks, and technical debt.
  • Use Case: A new developer joins a project with millions of lines of code. They can use this Skill to get a high-level overview (L0), understand the architecture (L1), and then dive into specific domains (L2) and modules (L3) to quickly become productive.

Quick Start

Use the codebase scanner to perform a full scan of the project and generate all documentation levels.

FAQPage Schema
How do I generate documentation for a large codebase to understand its architecture quickly?

You can scan a codebase of any size to generate hierarchical documentation from L0 to L3, providing a high-level overview down to specific modules. This allows developers and AI agents to instantly understand project architecture and navigate complex code efficiently.

How does incremental scanning work for updating codebase documentation?

Incremental scanning works by analyzing only changed files using git-diff, rather than rescanning the entire project. This enables faster documentation updates and allows AI agents to quickly process recent modifications without repeating a full codebase scan.

Can I extract business rules and security risks from my codebase automatically?

Yes, semantic analysis automatically extracts business rules, security risks, and technical debt from your codebase. This helps identify critical code sections and navigate complex project structures without manually reviewing every file.

Does codebase scanning work for projects with millions of lines of code?

Yes, the codebase scanner supports projects of any size, including codebases with millions of lines. A new developer can use it to get an L0 overview, understand the L1 architecture, and dive into L2 domains and L3 modules to quickly become productive.

What is the best way to help an AI agent navigate a complex codebase?

The best way is to perform a full codebase scan to generate hierarchical documentation and semantic analysis. This enables AI agents to understand project architecture, identify critical sections, and navigate complex codebases efficiently without manual context building.

When should I use incremental scanning instead of a full codebase scan?

Use incremental scanning when you need faster documentation updates for changed files only, rather than regenerating all documentation levels. A full scan is necessary initially to establish the L0-L3 baseline, after which git-diff scanning maintains it efficiently.
