* Design token implementation
* State management patterns in use
* Testing strategies and coverage expectations
* Build pipeline and deployment process
* Leverage context data before asking users
* Focus on implementation specifics rather than basics
* Validate assumptions from context data
* Request only mission-critical missing details
* Component scaffolding with TypeScript interfaces
