Conciseness

Lean and imperative throughout — no background concepts explained, every bullet instructs — but the time-sensitive details ('no tagged release as of 2026-10-19', 'after v1.42.0') sit inline in the workflow rather than in a deprecated/old-patterns section, a minor instance of content that could be trimmed or relocated.

Actionability

Fully executable, copy-paste-ready commands with exact arguments for every common case ('--groups', 'http', 'http spans', 'http http.request.method'), plus env-var setup, a test-script invocation, and concrete decision rules for naming and attribute selection.

Workflow Clarity

Five clearly sequenced steps with an explicit output-specification step ('include the group name, released version, and source URL'), but the only feedback loop ('after changing the parser, run ... test script') covers script maintenance rather than validating the task result mid-flow — a minor validation gap.

Progressive Disclosure

A 42-line overview body that clearly signals one-level-deep references ('see references/semconv-selection.md', 'to target a version ... see references/sdk-semconv-packages.md'); all referenced bundle files exist and the references point only to scripts and external URLs, with detail appropriately split out of SKILL.md.

Specificity

Enumerates several concrete tasks — 'selecting released semantic convention groups, attributes, or span naming rules', 'checking semantic convention compliance', 'checking which semantic-conventions version a language SDK's semconv package exposes' — though the core 'what' ('semantic convention lookup and naming guidance') is slightly generic rather than a fully comprehensive concrete action list.

Completeness

Clearly answers both: the 'what' ('OpenTelemetry semantic convention lookup and naming guidance') and an explicit 'Use when...' with three concrete trigger clauses, matching the both-what-and-when-with-trigger-phrases anchor exactly.

Trigger Term Quality

Good coverage of natural terms users in this domain would say ('semantic convention', 'attributes', 'span naming rules', 'compliance', 'semconv package', 'SDK'), but misses common variations such as 'otel' or 'instrumentation naming', so it falls just short of the comprehensive-synonyms anchor.

Distinctiveness Conflict Risk

Clear niche (OpenTelemetry semantic conventions) with distinct, domain-specific triggers ('semconv package', 'span naming rules', 'semantic convention compliance'), making conflict with other skills unlikely.
