# DevTune agent spine (init template → `.devtune/ai/AGENTS.md`)

## Shift start
1. `npx devtune doctor` (or monorepo doctor)
2. `npx devtune verify` then `npx devtune smoke` (or battery)
3. Red → stop; paste full output to human
4. Green → one feature chunk only

## Cadence
- Every chunk: verify  
- Every 30–60 min: verify + smoke  
- Never delete or skip gates to stay green  

## Laws
- thing/bind/collide string-literal ids; object-literal settings at call site  
- Packs for physics/movement/camera — declare tune yourself  
- No central CONFIG; no raw Rapier world  
- No bind(parent Group); collide pack bodies  
- No L/2 as game keys
