Compute Engine Spot Capacity Advice

The compute-spot-capacity-advice skill provides telemetry and architectural guidance to assess the obtainability of Google Compute Engine (GCE) Spot VMs before submitting creation requests.

Spot VMs run on spare compute capacity and are subject to preemption. Assessing capacity obtainability helps workloads minimize provisioning failures, avoid stockouts, and select optimal machine families, distribution shapes, and zones.

[!NOTE] Spot Capacity Advice is served on the Compute Engine Beta API (compute.beta.AdviceService.Capacity, POST /compute/beta/projects/{project}/regions/{region}/advice/capacity) and requires no project allowlisting. Always invoke it via the gcloud beta release track (gcloud beta compute advice capacity) — never omit beta even if gcloud compute advice capacity appears in --help, as the v1 backend rejects SPOT. Flex-start Capacity Advice (--provisioning-model=FLEX_START) is currently in Private Preview; for public workloads without explicit allowlists, always use --provisioning-model=SPOT.
