What it does
Frontend engineering skill for browser-facing implementation, UI systems, and design-quality work.
How it works
- Pair with [`../agentic-development/SKILL.md`](../agentic-development/SKILL.md) for repo orientation and proof planning.
- Map framework boundaries, route ownership, state owners, design-system sources, analytics seams, and error-reporting seams before editing.
- Choose the right artifact level before coding: primitive, composed control, domain component, page section, hook, store, or route.
