它能做什么

Build a compact local SQLite index of every function, class, method, interface and type across your repos, so an agent finds a symbol's file:line and signature in one lookup instead of a tree-wide grep plus whole-file read.

codemap

Agents burn tokens re-discovering the same code: grep a name across the trees, then read the file the hit lives in (often the whole thing) to see the signature. codemap collapses that to one short record — file:line plus the signature. Pure Python standard library: no network, no model call, no dependencies.

The executable is {baseDir}/bin/codemap. Build the index once over your roots, then query it instead of grepping.

When to use this

Use it whenever you are about to grep a codebase for where a function/class/type is defined, or need a symbol's signature. Build the index at the start of a session over the repos you will touch, then find instead of grepping. Best on Python and JS/TS/JSX/TSX projects.

How to use it

1. Build (or rebuild) the index over one or more roots

{baseDir}/bin/codemap build   ...

Idempotent — build deletes and re-inserts. Skips node_modules, .next, .git, dist. Rebuild after large edits (there is no file-watcher).

2. Find a symbol

{baseDir}/bin/codemap find scan            # exact match by default
{baseDir}/bin/codemap find scan --like     # substring match
{baseDir}/bin/codemap find Pipeline --kind class
{baseDir}/bin/codemap find scan --json     # machine-readable

find exits non-zero when nothing matches, so it drops into a && chain.

3. Outline a file / see stats

{baseDir}/bin/codemap file src/app/page.tsx
{baseDir}/bin/codemap stats

What it indexes

  • Python: top-level functions, classes, methods (incl. async def).
  • JS / TS / JSX / TSX: function declarations, exported arrow consts, classes, interfaces, type aliases.

Notes for the agent

  • Reference the tool as {baseDir}/bin/codemap — never hardcode a path.
  • Extraction is regex-based, not a full parser: it catches common declaration forms but misses exotic ones (decorated factories, re-exports, dynamically assigned names). It answers "where is X defined", not "who calls X".
  • The index is a snapshot — rebuild after large edits.
