4// agentmap — the repo map your coding agent is *forced* to use.
6// A ts-morph code-relationship map for TypeScript/JavaScript repos. Unlike
7// one-shot "pack the repo into a prompt" tools, this is a QUERYABLE, RANKED
8// map: PageRank importance (approach from Aider's repo map), Aider-style
9// symbol ranking, a token-budgeted `--map` digest, and a single `--any`
10// router (file → symbol → feature → live git-grep) — wired into the agent
11// loop via a post-commit auto-refresh + a PreToolUse hook.
13// Near-zero deps (ts-morph only). Runs in the target repo's cwd.
14// Algorithm credit: Aider's repo map (Apache-2.0) — github.com/Aider-AI/aider
