Conciseness

The body is ~38 lines of lean tables and terse directives with zero padding and no explanation of concepts Claude already knows (e.g., "None required. Use advertised read-only Azure tools or CLI queries."). Every section earns its place.

Actionability

The workflow gives concrete, executable directives ("Capture exact code, nested message, operation, and AKS resource", "Require every qualifier; codes are not substrings", "require explicit approval before every mutation") and the Error Handling table maps inputs to concrete responses. It falls short of anchor 5 only because the per-error verification mechanics (e.g., `az vm list-skus`, `az aks check-acr`) live entirely in the catalog reference rather than the body, leaving minor gaps in copy-paste-ready specifics.

Workflow Clarity

The four-step workflow is a clear sequence with explicit validation checkpoints: the qualifier gate in step 2 ("Require every qualifier"), read-only verification in step 3, and the mutation approval gate in step 4 ("require explicit approval before every mutation"). The Error Handling table supplies recovery routing for non-matching inputs, fulfilling the error-recovery expectation of anchor 5.

Progressive Disclosure

The body is a lean overview and the bulk detail (the signature catalog) is correctly split into a single, clearly signaled, one-level-deep reference — "Use the [catalog](references/error-code-map.md)" — which exists as a real file with no further nesting. Navigation is trivial.

Specificity

"Lookup documented AKS fixes" is a concrete action, reinforced by concrete routing behavior ("use aks-troubleshooting or azure-diagnostics") and fully enumerated matching conditions with no vague language. It falls between anchor 3 (1-2 concrete actions) and anchor 5: the action list itself is short, but everything stated is maximally concrete; the minor gap is that the deliverables (cause, fix, Learn citation) are not stated in the description.

Completeness

The 'what' is explicit ("Lookup documented AKS fixes") and the 'when' is explicit with concrete trigger phrases ("only when the prompt includes an exact catalog signature and all of its qualifiers" followed by the enumerated signatures, plus "Never use for quota errors..."). This matches the anchor-5 example structure of clear what + concrete when.

Trigger Term Quality

Trigger terms are the exact strings users paste from AKS error output ("VMCannotFitEphemeralOSDisk", "'NodeImageVersion is not accepted'", "ZonalAllocationFailed with insufficient zone capacity") plus explicit negative triggers ("quota errors, code-only or bare wrappers"). Coverage is good but not comprehensive: several catalog signatures (K8sVersionNotSupported, OperationNotAllowed, LinkedAuthorizationFailed, OrasPullUnauthorized/CSE 212, ACR 401 image pull) are only covered by the abstract phrase "an exact catalog signature" rather than by their actual keywords, so a few natural terms are missing.

Distinctiveness Conflict Risk

A clear niche (documented AKS known-issue lookups keyed on exact catalog signatures) with explicit negative triggers and explicit redirects to sibling skills ("use aks-troubleshooting or azure-diagnostics"), making wrong-skill triggering very unlikely.
