Generate A2UI 0.8 protocol compliant UI code. Use when building agent-driven interfaces, generating JSONL messages for surfaceUpdate/dataModelUpdate/beginRendering, creating forms, lists, cards, or any UI components that render across web/mobile/desktop platforms.

Apply DDD tactical patterns (Entities, Value Objects, Aggregates, Domain Services, Repositories) and strategic design (Ubiquitous Language, Bounded Contexts). Use when modeling complex business logic.

Build a WebF bridge module/native plugin using the module-codegen workflow (*.module.d.ts → codegen → Dart implementation → registration → JS usage). Use when the user mentions module-codegen, bridge module, native plugin, *.module.d.ts, or registering a module.

Create CRPO-compliant welcome email sequences for therapy practices that build trust and reduce no-show rates. Use when new leads fill out contact form but before first appointment.

Performance optimization for React web applications. Use when optimizing renders, implementing virtualization, memoizing components, or debugging performance issues.

Use this skill whenever the user wants to set up, configure, or refactor shadcn/ui in a Vite + React + TypeScript project (non-Next.js), including Tailwind, components.json, theming, and component structure.

Use PROACTIVELY this agent when you need to design and create optimal Claude Code subagents, update existing agents with new capabilities, revise agent configurations, analyze project requirements to identify specialized roles, or craft precise agent configurations with appropriate tool permissions and model tiers. When the user specify "Create or Update subagent [name]", this skill must be triggered.
