Mostly efficient, but the E-E-A-T/YMYL rationale is repeated across the intro, Quick Reference, and Explain sections, and some background ('held to the highest trust standards') is concepts Claude already knows.

Provides copy-paste-ready disclaimer text for medical, financial, legal, and affiliate content, plus concrete detection guidance (check for a disclaimer element near the top of <main>/<article>, verify FTC disclosure before the first <a> with a referral parameter).

A single-purpose skill with a clear Check → Fix sequence (numbered 1–7) and a Code Review section that functions as verification; no destructive/batch operations so no feedback-loop cap applies.

Well-organized overview sections with a single, clearly signaled one-level-deep reference ('see references/rule.md') that exists as a real file holding the detailed HTML examples.

Lists multiple concrete actions — 'auditing YMYL content pages for trust signals', 'generating disclaimer copy for medical or financial content', and 'reviewing affiliate disclosure requirements under FTC or ASA guidelines' — rather than vague language.

Opens with an explicit 'Use when' clause and answers both what it does (audit/generate/review disclaimers) and when to use it (YMYL, medical/financial content, affiliate disclosures).

Covers natural terms a user would say ('disclaimer copy', 'medical or financial content', 'affiliate disclosure requirements', 'FTC or ASA guidelines'); the 'YMYL' and 'trust signals' jargon is offset by these plain-language triggers.

Targets a clear niche (regulatory disclaimers for sensitive/affiliate content under FTC/ASA) with triggers unlikely to fire for unrelated SEO skills.
