Conciseness

The ~24-line body is pure routing signal with zero padding: it never explains what Azure, VMs, or scale sets are, and every sentence either classifies intent or names a file to open ("never route directly to references/* files"). It matches the lean anchor — every token earns its place — and sits well above anchor 4's "minor instances of over-explanation", of which there are none.

Actionability

Guidance is concrete and executable for a router skill: an exact decision procedure ("classify the user intent below, open the matched workflow file, then load only the reference files that workflow requests"), a routing table mapping intents to specific file paths, and a crisp disambiguation rule ("route to azure-prepare" for app deployments). It is not a 5 because the guidance bottoms out at file pointers — the workflow internals, fallback behavior, and the compute_vm_* tools named in the description are not carried into the body, leaving minor gaps.

Workflow Clarity

The routing sequence is clear and well-guarded: mandatory workflow-first routing, an intent table with explicit "Use when" conditions, and an instruction to "ask a clarifying question to disambiguate between the workflows" when intent is unclear — matching anchor 4's clear sequence with only minor gaps. It falls short of anchor 5 because there is no checkpoint after opening a workflow (e.g., confirming the workflow actually covers the request before proceeding, or a fallback when none matches).

Progressive Disclosure

Scored against the actual bundle per the guideline: all four routing-table links ("workflows/vm-recommender/vm-recommender.md", "workflows/vm-creator/vm-creator.md", etc.) point to files that do not exist in the bundle, while the four real reference files (references/vm-families.md, vm-quotas.md, retail-prices-api.md, vmss-guide.md) are never linked from SKILL.md and are therefore unreachable from the entry point. The body's structure is well-designed in the abstract, but navigation is broken in practice — every link is dead and the actual supporting material is buried, matching anchor 2 rather than anchor 3 (where references are at least present and signaled).

Specificity

The description lists many concrete actions and scopes ("create / provision / deploy / spin-up VM, recommend VM size, compare VM pricing", "CRG association, CRG disassociation", "machine enrollment (EMM)") and even names specific tools ("compute_vm_list-skus / compute_vm_list-images / compute_vm_check-quota"), but the capability statement itself is a terse "Azure VM/VMSS router" with the rest delivered as a keyword list, leaving minor gaps in what the router actually does.

Completeness

It explicitly answers both questions: "what" via "Azure VM/VMSS router" with named tools, and "when" via an explicit "WHEN:" clause with concrete trigger phrases, matching the anchor for clearly answering both. The "what" is terse, but it is explicit and paired with a "PREFER OVER" directive that sharpens intent, so this is not the anchor-4 case of a weakly specified "when".

Trigger Term Quality

Trigger coverage is comprehensive with abundant synonyms and natural user phrasing: "create / provision / deploy / spin-up", "VMSS, scale set, autoscale, burstable", "lightweight server, website, backend, GPU, machine learning, HPC simulation, dev/test", plus expansions of abbreviations ("capacity reservation (CRG)", "Essential Machine Management"). It clearly matches the comprehensive-synonyms anchor and is well above anchor 4's "a few natural terms missing".

Distinctiveness Conflict Risk

The Azure VM/VMSS compute niche is clear and the explicit "PREFER OVER mcp__azure__get_azure_bestpractices for VM create intents" resolves the closest tool conflict. However, very broad triggers like "website, backend, monitor, workload, dev/test" risk overlap with app-deployment or monitoring skills, keeping it at anchor 4 (minor overlap risk with closely related skills) rather than 5.
