Anti-Hallucination Guidelines

CRITICAL: Before implementing anything:

1. Discover project commands first - Do NOT assume bun, npm, make, etc. exist
2. Read CLAUDE.md - Every project may have different conventions
3. Verify tools exist - Check for Makefile, justfile, package.json, pyproject.toml, etc.
4. Never guess test commands - Find the actual test runner used by this project

Lean Code

Write the smallest change that fully does the job — and that the next person can change without fear. Two goals at once: minimal footprint, easy to change.
