# Coding Posture

- The product is one file: `skills/coding-posture/SKILL.md`. No engine, no selection code.
- Modes are procedural checklists, not personas. Keep them aimed at situations models reliably get wrong.
- A mode never overrides user/project/safety instructions.
- Keep `SKILL.md` scannable: short checklists, plain mode names, no persona theatrics. Enrich modes only with practices that have evidence behind them.
