The body is lean and assumes Claude's competence — it skips generic explanations and only adds non-obvious value such as 'avoids the paid SplitText plugin and keeps spaces intact', matching the 'lean and efficient; every token earns its place' anchor rather than level 2's mild over-explanation.

Provides fully executable, copy-paste-ready HTML, CSS, and GSAP JS with concrete values (duration 0.8, stagger 0.035, start 'top 82%'), plus a React cleanup pattern — matching the 'fully executable code; copy-paste ready' anchor rather than level 2's pseudocode or missing details.

For this simple single-purpose skill the single action is unambiguous, and the 'Quick Checks' section acts as a verification checklist (hidden-before-init, aria-label, spaces preserved, reduced-motion, SPA cleanup); no destructive/batch operation is present to cap the score at 2.

This is a simple, single-purpose skill with no need for external references, and its content is split into clearly organized sections (Use When, Motion Defaults, HTML, CSS, GSAP, React, Taste Rules, Quick Checks); per the simple-skills note, well-organized sections earn a 3 with no bundle files required.

Lists multiple concrete actions and specifics: 'Create masked staggered word reveals on scroll', 'GSAP ScrollTrigger', 'reveal word-by-word through an overflow mask', matching the 'lists multiple specific concrete actions' anchor rather than the partial coverage at level 2.

Explicitly answers both what ('Create masked staggered word reveals on scroll with GSAP ScrollTrigger') and when via an explicit 'Use when...' clause with concrete triggers, matching the level-3 anchor and exceeding level 2 which has 'what, but when is missing or only implied'.

Covers natural terms a user would say — 'headings, hero copy, section titles, or editorial text', 'reveal word-by-word', 'scroll', 'overflow mask' — matching the 'good coverage of natural terms' anchor rather than level 2's 'some relevant keywords but missing common variations'.

Occupies a clear niche (GSAP ScrollTrigger masked word-by-word reveal) with distinct, specific triggers unlikely to fire for unrelated skills, matching the 'clear niche with distinct triggers; unlikely to conflict' anchor rather than level 2's overlap risk.
