ts-codemap

A persistent, file-based map of a TypeScript/JavaScript codebase. The build script walks the target repo with the TypeScript compiler API (via ts-morph), writes a graph of symbols and edges to .codemap/graph.json, and a human-readable summary to .codemap/MAP.md. Other skills read these instead of running Glob/Grep/Read loops over raw source.

For Java/Go/Python/Rust, use the sibling codemap skill (tree-sitter based) — it writes the same .codemap/graph.json schema, so consumer skills don't care which one ran.

Quick start

# Full build (run from repo root, or pass a target path)
/ken-swe:ts-codemap build

# Incremental update (only re-parses files whose SHA256 changed)
/ken-swe:ts-codemap update

Both commands execute the bundled scripts via npx tsx. They install dependencies inside the skill folder on first run; the target repo gets .codemap/ (committed) and .codemap/cache/ (gitignored).
