- Engineers are expected to thoughtfully incorporate AI tools such as Claude Code, GitHub Copilot, or similar into their daily workflow whenever they meaningfully improve productivity and software quality
- We use AI for tasks like scaffolding, debugging, documentation, testing, and accelerating repetitive work, but AI never replaces engineering judgment
- You remain accountable for the architecture, trade-offs, correctness, security, and quality of everything that ships
- AI is a force multiplier for great engineers, not a substitute for them
