sunpeak

Use when working with sunpeak, or when the user asks to "build an MCP App", "build a ChatGPT App", "add a UI to an MCP tool", "create an interactive resource for Claude Connector or ChatGPT", "build a React UI for an MCP server", or needs guidance on MCP App resources, tool-to-UI data flow, simulation files, host context, platform-specific ChatGPT/Claude features, or production builds. For testing (e2e, visual regression, live tests, evals), see the test-mcp-server skill.

Use when testing MCP servers -- e2e tests with the sunpeak inspector, visual regression testing, live testing against real ChatGPT, multi-model evals, Playwright configuration, or scaffolding test infrastructure with "sunpeak test init". Works with any MCP server (Python, Go, TypeScript, etc.), not just sunpeak projects.
