Downloads any open-source repository's source code, builds an AST-based code graph, reads the core implementation files, and generates a comprehensive, shareable HTML architecture report.

29 5No licenseUpdated 2026-06-29

Overview

This skill acts as a deep code comprehension assistant that bypasses superficial documentation and README files. By combining `opensrc` to retrieve actual source code across ecosystems (npm, PyPI, GitHub) and `graphify` to map structural relationships, it pinpoints critical modules and god nodes, reads their implementation directly, and compiles a self-contained HTML breakdown detailing architecture, core abstractions, and end-to-end flows.

Capabilities

  • Fetches real source code for packages from npm, PyPI, crates.io, and GitHub
  • Builds local code graphs using AST analysis via graphify
  • Identifies central code components (god nodes) and system community structures
  • Reads and analyzes actual source files to trace control and data flow
  • Generates a self-contained, beautifully formatted HTML report outlining repository architecture and contribution entry points

Best for

Learning a new open-source library or framework from its implementation rather than docs, Onboarding onto a complex, unfamiliar codebase quickly, Preparing to contribute or extend an external repository by identifying key entry points and core abstractions

Security considerations

Executes external command-line utilities and downloads code repositories locally from public registries and GitHub, which should be done within a trusted environment.
