The body is lean and action-dense — concrete commands and workflow steps with no explanation of concepts Claude already knows; the few repetitions (e.g. null triage_report handling) serve distinct workflows and earn their place.

Provides copy-paste-ready executable commands throughout — 'snouty doctor --json', 'snouty runs --json show ${RUN_ID}', 'snouty runs --json events ${RUN_ID} ${PROPERTY_NAME}' plus a jq pipeline — with real variable names and exact field paths.

Multiple workflows are clearly sequenced with numbered steps and explicit validation checkpoints — the Preflight 'Proceed only when ok is true', the null-report stop in Triage step 2, and a final Self-Review checklist — plus error-recovery (retry with larger -n).

SKILL.md is an overview that signals each reference at the point of need, tells Claude not to load them all up front, and the four cited files (logs.md, properties.md, run-discovery.md, run-info.md) all exist and stay one level deep (properties.md→logs.md is a peer reference, not nested).

Enumerates multiple concrete actions — 'look up runs, check status, investigate failed properties (assertions), view metadata, download logs, inspect findings, and examine environmental details' — matching the multiple-specific-actions anchor.

The colon clause answers 'what' (the enumerated actions) and 'Load after a run completes or when investigating a failure' is an explicit 'when' trigger, satisfying both halves.

Includes natural triage phrases a user would actually say — 'investigating a failure', 'what happened in a run', 'test reports', 'failed properties', 'logs' — giving good coverage of natural trigger terms.

Scoped to 'Antithesis test reports' and 'failed properties (assertions)', a clear niche with triggers unlikely to fire for unrelated skills.
