diagnose
Use when the user reports that a Zilliz Cloud cluster or Milvus collection is unhealthy, slow, stuck, returning errors, hitting quotas, or otherwise misbehaving — or when they ask "what's wrong with...", "why is ... slow", "diagnose ...", "troubleshoot ...".
Install
With your agent
Install OMGSkills skill "zilliztech/zilliz-plugin:plugins/zilliz/skills/diagnose" into this agent's normal skills directory: call the OMGSkills MCP get_install_plan tool for your agent and run the script it returns (it installs only the pinned commit and verifies SKILL.md), and stop if MCP or the pin is unavailable. Do not overwrite or change existing skills without asking me.
Manual command
git clone https://github.com/zilliztech/zilliz-plugin /tmp/zilliz-plugin && ln -s /tmp/zilliz-plugin/plugins/zilliz/skills/diagnose ~/.claude/skills/diagnoseFrom README
Prerequisites CLI installed and logged in (see skill). For cluster diagnosis: a cluster context, or pass --cluster-id explicitly. For collection diagnosis: the cluster context must point at the cluster that owns the collection (see skill). Scope This skill performs read-only diagnosis using existing zilliz commands. It does NOT mutate clusters, collections, indexes, or data. Every recommendation is presented as a suggestion plus the exact next command the user can run themselves. Two entry points: | User says | Use section | |---|---| | "diagnose my cluster", "cluster is slow / stuck / unhealthy" | Cluster Diagnosis | | "diagnose this collection", "search is slow on X", "X won't load" | Collection Diagnosis | When the user's intent spans both (e.g. "everything is slow"), run cluster diagnosis first — a collection-level symptom often has a cluster-level cause. Cluster Diagnosis Follow this checklist in order.
