Feature Lifecycle

One skill, eight focused phases. Each phase tells the agent exactly what to do for that step — inputs, steps, outputs, and a gate to know it's done.

1. Discovery        → what already exists, what the user means
2. Domain design    → ASCII architecture + naming + user approval
3. Domain TDD       → value tests + aggregate tests + protocol + impl class (Red → Green)
4. Composition      → plug the aggregate onto parent + facade forwarders
5. Infrastructure   → port conformance + push routing + wire format
6. Views            → SwiftUI bind to the facade; no ViewModel layer
7. Docs             → feature doc + aggregate audit + visual artifacts
8. Verify           → pre-commit checklist + tests + build

The phases are sequential. Don't skip ahead. If a phase's gate isn't met, go back.
