# Repo Mapping Skill

When entering a repo:
1) Read README.md
2) Identify entrypoints (app main / server startup / CLI)
3) Identify config (env vars, .env.example, config files)
4) Identify test/lint scripts (package.json, pyproject.toml, Makefile, etc.)
5) Write a 10-line "repo map" in the PLAN before changing code
