SYSTEM DOCUMENTATION & REQUIREMENTS

What problem does it solve?

Map unfamiliar codebases into a structured knowledge graph that captures files, functions, dependencies, and architecture, helping teams onboard faster and maintain clarity.

Core Features & Use Cases

  • Knowledge-graph generation: Systematically decompose a codebase into nodes (files, functions, classes) and edges (imports, calls, extends) to reveal structure.
  • Architecture layering: Assign files to API, service, data, UI, and config layers with descriptive context.
  • Guided learning tours: Produce a pedagogical tour (5–15 steps) from entry points to deeper dependencies to aid onboarding and reviews.
  • Documentation-ready output: Generate a machine-friendly graph plus human-readable tours and diagrams for architecture docs.

Quick Start

Run the codebase-understanding skill against your repository to generate the knowledge graph and guided tour.

FAQPage Schema
How do I analyze an unfamiliar codebase for onboarding?

To analyze an unfamiliar codebase for onboarding, the skill decomposes repositories into a structured knowledge graph of files, functions, and dependencies, then generates a guided learning tour to help you navigate the architecture.

What is a codebase knowledge graph and how does it work?

A codebase knowledge graph maps files, functions, and classes as nodes, and imports, calls, and extensions as edges. This structured representation reveals underlying architecture and dependencies for clearer documentation and reviews.

Can I generate architecture documentation from my repository automatically?

Yes, you can generate architecture documentation automatically. The skill produces machine-friendly graphs alongside human-readable tours and diagrams, assigning files to API, service, data, UI, and config layers with descriptive context.

How do I create a guided tour for a codebase review?

You create a guided tour for a codebase review by running the skill against your repository. It produces a pedagogical tour of 5 to 15 steps, progressing from entry points to deeper dependencies to aid onboarding and architectural reviews.

What's the best way to visualize code dependencies for refactoring planning?

The best way to visualize code dependencies for refactoring planning is mapping the codebase into a knowledge graph. This captures structural edges like imports and calls, revealing architectural layers to inform your refactoring strategy.

Does this codebase analysis approach work without specific dependencies?

Yes, this codebase analysis approach works without specific dependencies. The skill requires no external dependencies to decompose your repository into navigable nodes, edges, and architectural layers for onboarding and documentation.
