Conciseness

The body is efficient and skill-specific (snouty commands, endpoint behavior, workflow steps) with no explanation of concepts Claude already knows, but a few sections could be trimmed — e.g., the long 'antithesis-mutation-testing' bullet and the Self-Review preamble. Fits 'Efficient; minor instances of over-explanation' rather than the 5 anchor's every-token-earns-its-place.

Actionability

Concrete, copy-paste-ready commands are given ('snouty doctor --json', the jq tenant lookup, 'snouty runs --json show ${RUN_ID}', 'snouty runs show <RUN_ID> --web') with named workflows, but some exact command forms (properties fetch syntax, search queries) are deferred to reference files. Mostly executable guidance with minor gaps, not fully self-contained.

Workflow Clarity

Workflows are clearly sequenced with explicit validation (preflight: 'Proceed only when the top-level ok is true and the api_key check's status is ok. Otherwise relay the failing check's message/notes and stop'), error-recovery loops ('If you aren't certain what caused the issue, consider downloading logs from other counterexamples... Compare each occurrence'), fallback branches for incomplete runs, and a self-review checklist. Matches the 5 anchor: explicit validation, feedback loops, and a checklist.

Progressive Disclosure

The ~150-line overview explicitly instructs 'Do NOT read them all up front — only read a reference file when you are told to' and names each of the five existing reference files at its point of need, with 666 lines of detail appropriately split out. The single cross-reference (properties.md → references/logs.md) is redundant with a direct body link, so no information is gated behind a two-level chain.

Specificity

The description lists eight concrete actions — 'look up runs, check status, investigate failed properties (assertions), view metadata, download logs, search events across all timelines, inspect findings, and examine environmental details' — giving comprehensive coverage of the triage domain. Not 4: there are no meaningful gaps in the action list within the stated scope.

Completeness

It clearly answers both 'what' (the explicit action list) and 'when' with a concrete trigger clause: 'Load after a run completes or when investigating a failure.' Matches the 5 anchor's 'explicitly answers both what AND when with concrete trigger phrases'.

Trigger Term Quality

Natural keywords users would say are present ('Antithesis', 'test reports', 'run', 'failure', 'failed properties', 'logs'), but a few natural terms and synonyms are missing (e.g., 'fuzzing'/'fuzz test', 'flaky', 'debug a run'). Fits the anchor 'Good keyword coverage; a few natural terms missing' rather than the 5 anchor's comprehensive synonym coverage.

Distinctiveness Conflict Risk

The 'Antithesis' product name plus niche-specific actions (triage reports, assertions, timelines) establish a clear niche with minimal conflict risk; sibling Antithesis skills (debug, workload) address different tasks. Not 4: no notable overlap risk remains.
