description

Preact 11 specialist skill: signals-based reactivity (v2 API with createModel/useModel), preact/compat migration from React, third-party embed widgets (shadow DOM isolation, IIFE bundles), Astro island integration (client:* directives, 5.0.1 or newer useId fix), and Fresh 2.x framework (Deno-native, islands + serializable props). Use when building Preact components, evaluating Preact vs React, migrating from React to Preact, embedding a widget on third-party pages, or working with Astro or Fresh projects. Do NOT use for React architecture in general (react-worker-bee), Next.js App Router configuration (react-worker-bee), or Deno infrastructure beyond Fresh (devops-worker-bee).
