# Send chitin-core 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": "chitin-core", "name": "chitin-core", "source": "tencent", "type": "skill", "category": "AI 智能", "sourceUrl": "https://clawhub.ai/adroidian/chitin-core", "canonicalUrl": "https://clawhub.ai/adroidian/chitin-core", "targetPlatform": "OpenClaw" }, "install": { "downloadUrl": "/downloads/chitin-core", "sourceDownloadUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=chitin-core", "sourcePlatform": "tencent", "targetPlatform": "OpenClaw", "packageFormat": "ZIP package", "primaryDoc": "SKILL.md", "includedAssets": [ "README-SYNC.md", "SKILL.md", "_meta.json", "config.json", "scripts/provider-sync.js", "scripts/router.js" ], "downloadMode": "redirect", "sourceHealth": { "source": "tencent", "slug": "chitin-core", "status": "healthy", "reason": "direct_download_ok", "recommendedAction": "download", "checkedAt": "2026-05-04T19:10:58.797Z", "expiresAt": "2026-05-11T19:10:58.797Z", "httpStatus": 200, "finalUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=chitin-core", "contentType": "application/zip", "probeMethod": "head", "details": { "probeUrl": "https://wry-manatee-359.convex.site/api/v1/download?slug=chitin-core", "contentDisposition": "attachment; filename=\"chitin-core-1.0.0.zip\"", "redirectLocation": null, "bodySnippet": null, "slug": "chitin-core" }, "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/chitin-core" }, "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/chitin-core", "downloadUrl": "https://openagent3.xyz/downloads/chitin-core", "agentUrl": "https://openagent3.xyz/skills/chitin-core/agent", "manifestUrl": "https://openagent3.xyz/skills/chitin-core/agent.json", "briefUrl": "https://openagent3.xyz/skills/chitin-core/agent.md" } } ``` ## Documentation ### chitin-core Route tasks to the cheapest capable model. Never crash on rate limits. ### Activation When spawning sub-agents or delegating tasks, use ModelRouter to select the optimal model. Trigger phrases: "route this", "spawn a sub-agent", "delegate", or any time you need to choose a model for a task. ### Route a Task node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js route "task description here" Returns JSON: {"tier":"MEDIUM","model":"google-antigravity/gemini-3.1-pro","confidence":0.85,"estimatedCost":0.005,"signals":["codeSignals:2×1.2=2.4"]} Use the returned model value in sessions_spawn. ### Handle Failures If a spawned session fails with a rate limit or error: node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js fail "provider/model" "error message" Then re-route — the failed model will be skipped: node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js route "same task" ### Check Health node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js health ### View Costs node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js costs ### Validate Config node ~/.openclaw/workspace/skills/chitin-core/scripts/router.js validate ### Workflow Receive task from user Run router.js route "" to get optimal model sessions_spawn with returned model If spawn fails → router.js fail "" "" → retry route Return result to user ### Tiers TierUse CaseModelsLIGHTGreetings, simple Q&A, status checksFlash, DeepSeek, gpt-5-mini, Groq, OllamaMEDIUMCode, summaries, standard tasksGemini Pro, gpt-5.2, DeepSeek ReasonerHEAVYArchitecture, complex reasoning, agenticgpt-5.2-pro, o3, Codex ### Override Tags Include in task text to force a tier: @light — force cheapest model @medium — force mid-tier @heavy — force most capable ### Graceful Degradation If all models in a tier are rate-limited, the router automatically: Tries adjacent tiers (escalate or downgrade) Falls back to local Ollama if configured Returns structured error with retry time (never crashes) ### Configuration Edit config.json in the skill directory to: Add/remove models per tier Adjust cost figures Tune classification boundaries ## Trust - Source: tencent - Verification: Indexed source record - Publisher: adroidian - Version: 1.0.0 ## Source health - Status: healthy - Item download looks usable. - Yavira can redirect you to the upstream package for this item. - Health scope: item - Reason: direct_download_ok - Checked at: 2026-05-04T19:10:58.797Z - Expires at: 2026-05-11T19:10:58.797Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/chitin-core) - [Send to Agent page](https://openagent3.xyz/skills/chitin-core/agent) - [JSON manifest](https://openagent3.xyz/skills/chitin-core/agent.json) - [Markdown brief](https://openagent3.xyz/skills/chitin-core/agent.md) - [Download page](https://openagent3.xyz/downloads/chitin-core)
