Conciseness

Every section encodes workflow-specific knowledge Claude would not have (evidence priority order, ordered stage list, case-sensitive path formats, "Zero targets with changed sample data commonly means a misspelled or mis-cased parser directory") with no padding and no explanation of concepts Claude already knows like GitHub Actions or KQL basics. Not 4 because no sentence can be identified as over-explanation to trim.

Actionability

The collector invocation is copy-paste ready with backtick continuation and enumerated optional parameters, and guidance is exact throughout: "Parsers/ASim<Schema>/IngestTimeParsers/<Parser>.yaml", the Sample Data fixture path format, concrete KQL examples like "| project-rename EventProduct = DeviceProduct", and the ordered stage list. Not 4 because the common failure cases are covered with specific, executable detail rather than minor gaps.

Workflow Clarity

The 7-step investigation workflow is clearly sequenced with explicit validation checkpoints: step 1 verifies run identity, "Do not diagnose from the PR's current Files changed view until comparing its current head SHA" guards against stale evidence, and "If artifact download fails... continue with job logs and explicitly state the evidence limitation" provides an error-recovery path. Not 4 because checkpoints and recovery loops are explicit rather than implicit.

Progressive Disclosure

The body stays a lean overview and cleanly offloads detail: "Read [failure-catalog.md](references/failure-catalog.md) for stage semantics, common signatures, and remediation patterns" points to a real, well-organized 165-line reference that itself contains no further bundle-file references, and the referenced scripts/Get-AsimItpValidationDiagnostics.ps1 exists at the exact path used in the command. One level deep, clearly signaled, easy navigation.

Specificity

"Diagnoses GitHub Actions runs for the ASIM ingestion-time parser validation workflow" plus "asks why an ITP target was missed or failed" and "exact evidence-based remediation" name several concrete actions in a precisely defined domain. Not 3 because it goes beyond 1-2 generic actions; not 5 because the capability list is narrower than the comprehensive multi-action anchor example.

Completeness

"Diagnoses GitHub Actions runs for the ASIM ingestion-time parser validation workflow" explicitly states what it does, and "Use when a user provides a run URL or ID, asks why an ITP target was missed or failed, or needs exact evidence-based remediation" gives concrete trigger phrases for when. Clearly matches the anchor requiring both what and when with concrete triggers, not the anchor-4 case where the when-clause is generic.

Trigger Term Quality

"run URL or ID", "why an ITP target was missed or failed", and "GitHub Actions runs" are natural phrases users would say. Not 5 because common synonyms and variations such as "CI", "build failure", or "parser validation failed" are absent.

Distinctiveness Conflict Risk

Terms like "ASIM ingestion-time parser validation workflow" and "ITP target" define a clear niche with distinct triggers that no generic CI-debugging or coding skill would match. Minimal conflict risk.
