codebase-mapping

What problem does it solve?

Codebases, especially large ones, are hard to understand and maintain. This skill provides a structured method to build a mental model of an unfamiliar project by mapping structure, entry points, and key patterns.

Core Features & Use Cases

• Directory structure summary and main module discovery
• Entry point identification and data flow tracing
• Dependency and pattern documentation for onboarding new contributors
• Use Case: A new engineer joins a monorepo and needs a quick map of critical modules and interfaces to start contributing.

Quick Start

Start by loading the repository, run a quick top-level pass to identify top-level folders, entry points, and package.json or requirements.txt files, then generate a summary report.
