BC nutanix-aiops
Use this skill whenever the user needs to operate a Nutanix estate through Prism Central (v4 REST API) — an estate/cluster health overview, cluster & host inventory and utilization, VM lifecycle across AHV and ESXi (list/get/power/create/update/clone/delete/migrate), storage containers, subnets/network, images & categories, data protection / DR (snapshots, recovery points, protection domains, VM protect, failover), alerts & events with alert RCA (analyze_alert), LCM firmware/software upgrades, capacity runway forecasting, and read-only diagnostics/RCA over the whole estate (cluster_health_rca, alert_triage_rca). Always use this skill for "Nutanix", "Prism Central", "AHV", "cluster health", "list VMs", "power on/off a VM", "clone/migrate a VM", "delete a VM", "snapshot", "recovery point", "protection domain", "failover", "why did this alert fire" / "root cause this alert", "LCM upgrade / firmware", "days until storage is full" / "capacity runway", "what's wrong with my cluster" / "diagnose the estate", "triage my alerts", when the context is a Nutanix cluster or Prism Central. Do NOT use when the target is a non-Nutanix platform — those belong to their own AIops-tools sibling; this skill is Prism Central v4 only. Governed Nutanix Prism Central operations with a built-in governance harness (audit, token budget, undo, descriptive risk-tier labels).

What is at stake
Medium-severity findings: the skill is probably honest, but read what alarmed the scanner.
Below is the worst case for this category. The finding here is medium: the guard saw a sign, not a proof.
The skill asks for more than the task needs: broad tool access, credential environment variables, binaries. Every extra permission widens the damage from a mistake or a compromise.
Narrow allowed-tools and the variable list to the minimum; replace binaries with readable sources or scripts.
How to improve
- Shorten the description to 1024 characters.
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
