Map-Codebase Skill

Purpose

When starting work on an existing codebase, Claude must discover its structure, patterns, and risks reactively — reading files on demand, accumulating context piecemeal. This skill runs a one-time parallel analysis and persists the results in docs/codebase/ so every future session loads structured context instead of starting blind.

Not for: greenfield projects you built from scratch (you already know the structure).
