- Use AI where probabilistic reasoning creates value; keep critical business rules deterministic.
- Evaluate prompts and model behaviour instead of relying on demos.
- Make latency, cost, privacy, security, fallbacks and observability architectural concerns.
- Keep humans accountable for requirements, design, review and production outcomes.
