      <DocsSection title="Connect Col MCP">
        <DocsText>Use short keywords and structured filters for catalog searches; queries are limited to 4,096 Unicode code points. The MCP agent guide covers exact-name ranking, multi-framework AND filters, verified preview availability, and the sandboxed HTML fallback.</DocsText>
        <DocsText>Connect your coding agent to Col to search libraries and verified components, then inspect their setup and source links. <code>render_component</code> then shows the chosen component live in the chat, using its verified library implementation with your CSS and color scheme. Unsupported previews are explicitly unavailable. The server is read-only and needs no credentials.</DocsText>

      <DocsSection title="Solid 2 and Quoin">
        <DocsText>Search with the <code>SolidJS</code> stack and library <code>quoin-ui</code>. Use <code>get_library</code> for exact version requirements, then <code>get_component</code> for the selected component’s published API declarations and Solid examples in <code>documentation.snapshots</code>. Your agent uses that evidence to implement the component in your application.</DocsText>
        <DocsCode code={`search_components({ "library": "quoin-ui", "query": "dialog", "stacks": ["SolidJS"] })\nget_library({ "slug": "quoin-ui" })\nget_component({ "id": "quoin-ui/Dialog" })`} label="MCP tool calls" />
        <DocsText>Quoin 0.6.0 requires <code>solid-js</code>, <code>@solidjs/web</code>, and <code>@solidjs/signals</code> at <code>2.0.0-rc.18</code>. Follow the linked official setup guide; a newer RC is not automatically compatible. Quoin is unstyled: the examples include CSS, and you supply your application’s styles.</DocsText>
        <DocsText>Optional <code>render_component</code> requests use the genuine Quoin implementation with the pinned Solid runtime. Check each component’s <code>preview.available</code> and limitations first. Rendering availability is separate from API and example coverage.</DocsText>
        <DocsNote>Quoin’s API references are published source and TypeScript declarations, not a separate documentation site. Snapshots identify their version and source; omitted declarations remain linked. Solid 1 compatibility, SSR, and your application’s installed versions are not inferred.</DocsNote>
      </DocsSection>

      <DocsSection title="Read the catalog">
        <DocsText>The plain-text catalog at <a href="/llms.txt"><code>/llms.txt</code></a> lists each library’s official URL, description, category, stacks, and use cases. Fetch it when researching a project so your agent starts from the current directory.</DocsText>
        <DocsCode code={`Read ${siteUrl}/llms.txt.\nFind UI libraries for [framework] that support [use case].\nShortlist three options and explain the tradeoffs.\nVerify required components, installation, and licensing\nagainst each library’s official documentation.\nLink your sources and state anything you could not verify.`} label="Agent prompt" />

      <DocsSection title="Set up an MCP server">
        <DocsText><a href="/integrations">Integrations</a> lists MCP servers and connectors for UI libraries and design tools. Each page has a config snippet for every client its provider documents, and a setup prompt for your agent.</DocsText>
        <DocsNote>Snippets read API keys from environment variables. Never paste a key into a config file or a chat.</DocsNote>
      </DocsSection>

        <DocsNote>Col’s component index is verified but partial. Missing entries mean support has not been recorded, not that the library lacks the component. Broad tags are not evidence of component support. The plain-text catalog contains library metadata, not the component index.</DocsNote>

      <DocsSection title="Contribute with an agent">
        <DocsText>When working in the repository, read <code>AGENTS.md</code> and <code>CONTRIBUTING.md</code> first. Every agent must follow the contribution rules and complete the applicable PR template checks. Link all resolved issues with closing references and verify they are closed after merge.</DocsText>
