explore-codebase

To build a mental map of a large codebase without loading everything into memory, this skill orchestrates targeted sub-agents to summarize specific regions. It creates a navigable structural map by decomposing files and synthesizing summaries without overwhelming your context window.

The best way to explore an unfamiliar codebase for onboarding is to dispatch focused agents to read modules and identify key entry points. This approach produces a consolidated structural map that highlights dependencies, module relationships, and invariants for rapid understanding.

Yes, you can map codebase dependencies to plan a large refactor. By building a scalable map of module relationships, the approach highlights architectural hotspots and invariants, providing the regional clarity needed to safely execute structural changes.

Structural codebase exploration with sub-agents works by dispatching focused agents to read specific modules and summarize their interfaces. A synthesis step then assembles these per-file summaries into a persistent map stored in shared state, constrained by a recursion cap.

No, exploring a sprawling codebase does not require loading all files into context. The skill applies per-file decomposition and a recursion cap to summarize regions independently, ensuring you can navigate large repositories without hitting memory limits.

You should use an automated codebase mapping tool when you need regional clarity for tasks like onboarding to unfamiliar repositories, navigating forks, or planning large refactors. It builds a persistent mental map to highlight dependencies and key entry points efficiently.
