The body is lean imperative guidance with no padding or explanation of concepts Claude already knows; specific values like '160–220ms for control feedback' and '12–16px radii' earn their tokens.

As an instruction-only design skill it provides concrete, specific directives ('Disable autoplay typing and large state motion for reduced motion', 'Connect ambiguous terms to deep-linked FAQ answers') rather than vague direction, meeting the executable-guidance bar.

'Establish the Story' gives a numbered 5-step sequence and a dedicated 'Validate' section lists explicit checkpoints (keyboard editing, quota/moderation/network states, focus/contrast/200% zoom, reduced motion).

The skill is a single self-contained file with no bundle directories and no nested references; well-organized section headers (Build the Visual System, Compose the Page, Validate, Avoid) provide clear navigation within one level.

The description lists multiple concrete actions and page patterns ('Create or redesign SaaS and AI product landing pages', 'product UI in the hero, prompt-to-output stories, audience tabs, compact feature modules, honest pricing comparisons, and FAQ handoffs') in third-person voice, matching the anchor for listing multiple specific concrete actions.

It explicitly answers both 'what' (create/redesign product landing pages where the workflow is the proof) and 'when' via an explicit 'Use for...' trigger clause, satisfying the anchor for clearly answering both what AND when.

It covers many natural terms a user would say ('SaaS and AI product landing pages', 'audience tabs', 'pricing comparisons', 'FAQ handoffs') with good breadth of variations, clearing the bar for good coverage even if some phrasing leans design-jargon-heavy.

The 'product proof' SaaS landing-page niche with workflow/interface-as-evidence framing is a clear, distinct trigger set unlikely to fire for generic web or design skills.
