Conciseness

Mostly lean and assumes Claude's competence (no generic OTel/Python primer), but the flush guidance is restated three times - in the Worked-example prose and in two near-duplicate anti-pattern rows ('Query Jaeger immediately after exercise' and 'Skip flushing pipeline') - which could be trimmed. Not a 5 due to that redundancy; not a 3 because the rest is efficient.

Actionability

Fully copy-paste-ready guidance throughout: a concrete `docker run` command with ports, complete Python SDK configuration, and a full executable test with real `requests.get` params and assertions covering the common case.

Workflow Clarity

Clear five-step sequence with an explicit validation checkpoint (the 'mandatory' force_flush + sleep before query) and an anti-patterns checklist, but there is no error-recovery feedback loop (what to do when the assert fails), which the 5 anchor calls for. The destructive/batch cap does not apply since querying a backend is neither destructive nor batch.

Progressive Disclosure

Clear overview with well-signaled one-level-deep references - references/query-api-and-ci-wiring.md, references/zipkin.md, references/tempo.md all exist as real files, are linked inline and listed in a References section, and are not nested. Content is appropriately split with bulk query-API, CI-wiring, and per-backend details pushed to reference files.

Specificity

Lists multiple concrete actions across three backends - 'query patterns', 'span set + parent-child + duration assertions', 'B3 single/multi-header propagation tests', 'dependency graph', 'TraceQL span selectors + structural operators' - with comprehensive coverage, matching the anchor for multiple specific concrete actions.

Completeness

Explicitly answers both 'what' ('Author integration tests that query a tracing backend for cross-service trace verification') and 'when' ('Use when verifying that a request produces the expected spans across service boundaries in a running Jaeger, Zipkin, or Tempo backend') with concrete trigger phrases.

Trigger Term Quality

Comprehensive natural-term coverage including synonyms for all three backends (Jaeger, Zipkin, Grafana Tempo) plus 'integration tests', 'tracing', 'cross-service trace verification', 'spans across service boundaries' - phrases a user would naturally say; not merely technical jargon.

Distinctiveness Conflict Risk

Clear niche (distributed-tracing integration testing against named OSS backends) with distinct, specific triggers and minimal overlap risk with other skills; unlikely to fire for the wrong skill.
