Mapping Codebases (deprecated)

Use tree-sitting instead.

Why

This skill wrote _MAP.md files to disk — a persisted symbol inventory per directory, generated once and read many times. That tradeoff made sense when scanning was expensive. It isn't: tree-sitting parses a 250-file repo in about 700ms and answers queries against the in-memory AST in under a millisecond.

A persisted map costs what a runtime scan does not — it goes stale, it needs regenerating, it gets committed, and it must be excluded from every other tool that walks the tree. Nothing was gained for that.
