Skill UI

RouterBase acts as a unified, OpenAI-compatible API gateway, allowing applications to route requests across diverse large language models (LLMs) like GPT, Claude, and Gemini. It helps developers migrate existing OpenAI SDK calls, implement sophisticated primary/fallback model selection based on cost, latency, and quality, and manage multimodal payloads (image, audio, video) from a single, standardized endpoint.

SvelteKit is the official full-stack framework built on Svelte, enabling developers to build fast, modern, and highly performant web applications. It provides comprehensive features including file-based routing, Server-Side Rendering (SSR), Static Site Generation (SSG), API routes, and progressive form actions, all while maintaining Svelte's zero runtime overhead. Use this skill when building complex, data-driven web platforms where performance and developer experience are paramount.

This skill acts as a routing layer for UI development tasks. It helps agents select the smallest useful UI skill context via the ui-skills CLI before implementation. It ensures efficient context loading by identifying the task category and loading only necessary skills, avoiding unnecessary overhead.

Design or review an AI agent tool registry or MCP router: document parameter schemas, caller authorization, runtime limits, effect-aware retry contracts and verification evidence before connecting tools to an agent runtime.
