Context Engineering Harness Bootstrap

For: Any team member setting up Claude Code on their repo
Time: 2–4 hours for a full build, 30 min for a minimal starter
What you get: A self-reinforcing AI development environment that enforces quality, loads context intelligently, tracks work, and improves itself over time.
