# Send Clawhub Skill to your agent Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually. ## Fast path - Download the package from Yavira. - Extract it into a folder your agent can access. - Paste one of the prompts below and point your agent at the extracted folder. ## Suggested prompts ### New install ```text I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete. ``` ### Upgrade existing ```text I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run. ``` ## Machine-readable fields ```json { "schemaVersion": "1.0", "item": { "slug": "clawhub-skill-2", "name": "Clawhub Skill", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/pathemata-mathemata/clawhub-skill-2", "canonicalUrl": "https://clawhub.ai/pathemata-mathemata/clawhub-skill-2", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/clawhub-skill-2", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawhub-skill-2", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "SKILL.md", "USAGE.txt" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "clawhub-skill-2", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-04-30T14:24:11.895Z", "expiresAt": "2026-05-07T14:24:11.895Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawhub-skill-2", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=clawhub-skill-2", "contentDisposition": "attachment; filename=\"clawhub-skill-2-0.1.4.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "clawhub-skill-2" }, "scope": "item", "summary": "Item download looks usable.", "detail": "Yavira can redirect you to the upstream package for this item.", "primaryActionLabel": "Download for OpenClaw", "primaryActionHref": "/downloads/clawhub-skill-2" }, "validation": { "installChecklist": [ "Use the Yavira download entry.", "Review SKILL.md after the package is downloaded.", "Confirm the extracted package contains the expected setup assets." ], "postInstallChecks": [ "Confirm the extracted package includes the expected docs or setup files.", "Validate the skill or prompts are available in your target agent workspace.", "Capture any manual follow-up steps the agent could not complete." ] } }, "links": { "detailUrl": "https://openagent3.xyz/skills/clawhub-skill-2", "downloadUrl": "https://openagent3.xyz/downloads/clawhub-skill-2", "agentUrl": "https://openagent3.xyz/skills/clawhub-skill-2/agent", "manifestUrl": "https://openagent3.xyz/skills/clawhub-skill-2/agent.json", "briefUrl": "https://openagent3.xyz/skills/clawhub-skill-2/agent.md" } } ``` ## Documentation ### Xrouter Xrouter is an open-source inference router that sits between OpenClaw and your LLM providers. It uses a fast, hardware-aware classifier to route each request to the most cost-effective model that can handle the task. This project is MIT licensed. See the MIT License. Core Features OpenAI-compatible reverse proxy at POST /v1/chat/completions. 3-tier classifier (0 = cheap, 1 = medium, 2 = frontier) with early stream cutoff. Hardware detection helper to recommend local engine. Provider selection wizard to choose local and cloud endpoints. Cache layer with Redis or in-memory LRU fallback. Full cloud mode when local inference is not viable. Token tracking dashboard at /dashboard.

Requirements Node.js 20+. Local classifier engine (optional). A frontier provider endpoint (required). Quickstart Install dependencies. (Optional) Start a local model server. Run the configuration wizard. Start the router. npm install npm run configure npm run dev How To Use Start your local model server (optional but recommended). Run the wizard to configure providers and models. Start the router. Send OpenAI-compatible requests to the router. Inspect routing decisions in response headers or the dashboard. Example local setup (Ollama): ollama pull llama3.1 ollama run llama3.1 Run the wizard: npm run configure Start the router: npm run dev Test a request: curl -i http://localhost:3000/v1/chat/completions \\ -H "Content-Type: application/json" \\ -d '{"model":"any","messages":[{"role":"user","content":"Fix this sentence: I has a apple."}]}' Look for these headers: X-Xrouter-decision: 0, 1, or 2. X-Xrouter-upstream: cheap, medium, or frontier. Open the dashboard: http://localhost:3000/dashboard Raw usage JSON: http://localhost:3000/usage Provider Selection (Terminal Wizard) Run: npm run configure The wizard: Scans hardware and recommends a local engine. Suggests a local classifier model. Lets you choose provider base URLs, API keys, and model overrides for cheap/medium/frontier routes. Writes upstreams.json and optionally updates .env. Quick Start Mode If your machine can run a local model, you can choose Quick Start. Quick Start auto-configures the local classifier. Cheap route always uses the same local model as the classifier to avoid Ollama model swapping. You only need to choose medium and frontier providers/models. On Apple Silicon (Ollama), the wizard lists installed Ollama models and can auto-download a recommended model. Routing Behavior The classifier is called for each uncached request. The first 0, 1, or 2 token returned decides the route. If classification fails, the router defaults to the frontier route. When the classifier is enabled, cheap, medium, and frontier routes must be configured. Compatibility The router accepts OpenAI-style requests and translates when needed. Provider type can be explicit (xrouter, openai_compatible, openai, anthropic, gemini, cohere, azure_openai, mistral, groq, together, perplexity) or auto. auto infers the provider adapter from the base URL or API key. Providers that expose OpenAI-compatible endpoints use the openai_compatible adapter. Anthropic/Gemini/Cohere streaming is translated into OpenAI-style SSE chunks. Non-OpenAI adapters currently support text-only messages and basic sampling params (temperature/top_p/stop). Token Tracking Dashboard GET /usage: returns cumulative token usage for cheap, medium, and frontier. GET /dashboard: UI that displays token split and totals.
