Codemap Config Setup

Goal

Write or improve .codemap/config.json so future Codemap calls stay focused on the code that matters for this repo.

Use this when

.codemap/config.json is missing
The existing config looks like a bare bootstrap instead of a real project policy
Codemap output is dominated by assets, fixtures, generated files, vendor trees, PDFs, screenshots, models, or training data
The project stack is obvious, but Codemap is not prioritizing the right parts of the repo

Workflow

Inspect the repo quickly before writing config
- Run codemap .
- If needed, run codemap --deps .
- Note the stack markers (Cargo.toml, Package.swift, *.xcodeproj, go.mod, package.json, pyproject.toml, etc.)
- Identify large non-code directories and noisy extensions
Decide whether config is missing, boilerplate, or tuned
- Missing: no .codemap/config.json
- Boilerplate: only generic only values, no real shaping, no excludes despite obvious noise
- Tuned: contains intentional project-specific includes/excludes, depth, or routing hints
Write a conservative code-first config
- Keep primary source-language only values when they help
- Add exclude entries for obvious non-code noise
- Set a moderate depth when the repo is broad
- Avoid overfitting or excluding real source directories
Prefer stack-aware defaults
- Rust: focus src, tests, benches, examples; de-prioritize corpora, sample PDFs, training data, large generated artifacts
- iOS/Swift: focus app/framework source, tests, package/project manifests; de-prioritize .xcassets, screenshots, snapshots, vendor/build outputs
- TS/JS: focus src, apps, packages, tests; de-prioritize dist, coverage, Storybook assets, large fixture payloads
- Python: focus package roots, tests, tool config; de-prioritize notebooks, data dumps, models, fixtures when they overwhelm code
- Go: focus packages, cmd, internal, tests; de-prioritize generated assets, sample data, vendor-like noise
Preserve user intent
