The body is dominated by lean, executable YAML templates and istioctl commands with minimal prose; the few non-code lines (intro sentence, 'When to Use' list, compact resource table) are short reference material rather than verbose concept explanation, fitting the 'lean and efficient' anchor over the 'some unnecessary explanation' of score 2.

Seven complete, copy-paste-ready VirtualService/DestinationRule/Gateway manifests plus full istioctl debugging commands provide fully executable guidance, matching the score 3 anchor rather than the pseudocode/incomplete anchor of score 2.

Verification tooling exists ('istioctl analyze') and a Do's/Don'ts checklist is present, but there is no explicit apply→validate→fix sequence with checkpoints for the config operations, so it sits at the score 2 anchor rather than the sequenced-feedback-loop anchor of score 3.

The skill is a single ~320-line file with no bundle files and all seven templates inline; sections are well-organized, but content that could be split into reference files is kept inline, fitting the score 2 anchor rather than the split-with-references anchor of score 3.

Lists multiple concrete actions — 'routing, load balancing, circuit breakers, and canary deployments' — matching the 'lists multiple specific concrete actions' anchor rather than the partial coverage of score 2.

Explicitly answers both what ('Configure Istio traffic management including...') and when ('Use when implementing...'), matching the score 3 anchor with an explicit 'Use when' trigger clause.

Natural trigger terms users would say — 'service mesh traffic policies, progressive delivery, or resilience patterns' — give good coverage of common phrasings, fitting the score 3 anchor over the 'some relevant keywords' of score 2.

'Istio traffic management' is a clear, narrow niche with distinct triggers unlikely to conflict with other skills, fitting the score 3 anchor rather than the overlapping scope of score 2.
