Lean, action-dense body with minimal prose between executable code blocks; assumes Claude's competence and avoids explaining basic concepts, with only a light justifying sentence in the Overview. Not scored 2 because there is no meaningful padding to tighten.

Every step ships copy-paste-ready, executable artifacts — bash for secrets managers, TypeScript HMAC verification and PII redaction, curl rotation test, and concrete tables — meeting the 'fully executable' anchor.

Steps 1-6 are clearly sequenced, and the destructive key-rotation procedure includes an explicit validation checkpoint ('Test connectivity' then 'Once confirmed working, revoke old key'), supported by a security checklist and error-handling table. Not capped at 2 because validation precedes the destructive action.

Single SKILL.md with well-organized sections and clear navigation; the only cross-skill reference (Next Steps -> clay-prod-checklist) is one level deep and clearly signaled, and no bundle files exist to require splitting. Meets the 'well-organized sections' standard for a self-contained skill.

Lists multiple concrete actions ('securing Clay integrations, rotating API keys, auditing access, or implementing webhook authentication') tied to specific domains (API keys, webhook secrets, data access control), matching the 'lists multiple specific concrete actions' anchor.

Explicitly answers what ('Apply Clay security best practices for API keys, webhook secrets, and data access control') and when ('Use when securing Clay integrations, rotating API keys...') with explicit triggers, hitting the top anchor.

Provides explicit natural trigger phrases ('clay security', 'clay secrets', 'secure clay', 'clay API key security', 'clay webhook security') that a user would plausibly say, giving good coverage.

Clear niche (Clay platform security) with 'clay'-prefixed triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers' anchor.
