Lists multiple specific concrete actions: look up runs, check status, investigate failed properties (assertions), view metadata, download logs, inspect findings, and examine environmental details.

Clearly answers both what ('Triage Antithesis test reports... look up runs, check status, investigate failed properties...') and when ('Load after a run completes or when investigating a failure'), with explicit trigger guidance.

Includes natural keywords users would say: 'test reports', 'run', 'failed properties', 'assertions', 'logs', 'findings', 'failure', 'triage', 'Antithesis'. These cover the domain well and match how users would describe investigating test failures.

Highly distinctive due to the specific product name 'Antithesis' and the focused domain of test report triage. Unlikely to conflict with generic testing or logging skills due to the specific tool reference and detailed action list.

The skill is mostly efficient and avoids explaining concepts Claude already knows, but there's some verbosity — the preflight section is somewhat lengthy, the 'Suggesting follow-up skills' section includes detailed descriptions of four other skills that could be more concise, and some guidance is repeated (e.g., the importance of logs is stated multiple times).

The skill provides concrete, executable commands throughout (e.g., `snouty runs --json properties`, `snouty runs --json events ${RUN_ID} ${PROPERTY_NAME}`, `snouty runs --json build-logs ${RUN_ID}`). Steps are specific with exact flags, field names to check, and clear decision points. The guidance is copy-paste ready and leaves little ambiguity about what to do.

Multiple workflows are clearly sequenced with explicit validation checkpoints — the preflight checklist stops at the first failure, the triage workflow checks for null triage_report before proceeding, incomplete runs have a distinct diagnostic path, and the 'Investigate failed properties' workflow includes feedback loops (downloading additional logs, comparing passing vs failing examples). The self-review section adds a final validation checkpoint.

The skill is well-structured as an overview that delegates detailed content to reference files (run-discovery.md, run-info.md, properties.md, logs.md) at exactly the point they're needed. References are one level deep, clearly signaled, and the skill explicitly instructs not to read them all up front. Navigation is intuitive.
