module-map

name: module-map description: Produce a one-screen map of an unfamiliar area of the codebase: entry points, modules, data flow, callers. Designed to be read in fifteen seconds. Use when the user says "I do not know this area", "give me the map", "zoom out", "orient me".

module-map

Orient fast in unfamiliar code. The deliverable is a map, not a tour.

Deliverable

A single response containing, in this order:

1. One-line summary of what the area does from a caller's point of view.
2. Entry points — every function, route, CLI command, event handler, or cron that starts a call chain in this area. File path + symbol.
3. Core modules — the two to five modules that contain the real logic. One line each describing their role.
4. Data flow — ASCII arrows showing the dominant path for the most common input. Skip error paths unless they matter architecturally.
5. External callers — who outside this area calls in, and through which entry points.
6. Hidden coupling — anything that looks independent but is not (shared singletons, global state, implicit ordering, undocumented contracts between files).
