perf-code-paths

Produces a token-budgeted, ranked map of important symbols (functions/classes/types) in a codebase. Useful for onboarding to large repos, before deep-review fan-outs, or when JIT context is needed instead of whole-file dumps.

Build a ranked, token-budgeted map of the codebase — the top files and their key symbols, ranked by how referenced they are — so you navigate to the right 3 files instead of reading 30. Triggers on "map the repo", "where is X", "how is this codebase laid out", "lay of the land", "I'm new to this repo", or at the start of work in a large/unfamiliar project. A zero-dependency repo-map (Glob + Grep + reference counts) that approximates a code graph; complements Sentinel's architectural map and saves tokens.

Maps unfamiliar codebases in phases: structure, entry points, data flow, patterns, landmines. Use before coding in new, inherited, or revisited projects.
