Conciseness

The body is task-specific and avoids explaining concepts Claude already knows, but the daily-capture rules are stated three times — the 'Daily UI Inspiration Capture Contract' (contiguous pixel-complete crops, full-page/section structure, cover-image prohibition) reappear nearly verbatim in workflow step 4 and again in the verify step. Anchor 3 fits: mostly efficient but could be tightened by consolidating the duplicated crop/evidence rules into one place.

Actionability

Guidance is concrete and executable for an instruction-only skill: specific grep terms ('mousemove', 'ScrollTrigger', 'parallax'), exact commands ('git diff --check', 'ffprobe'), a 2-second settle delay, explicit folder naming ('articles/YYYY-MM-DD-ui-inspiration-capture/'), and a full prompt anatomy template. Not 5 because the actual browser capture steps and manifest creation lack any commands or examples, leaving minor gaps.

Workflow Clarity

Eight clearly sequenced steps (inspect → decide → write → capture → video → article → verify → commit) with an explicit, checklist-style verification step ('verify exactly 5 inspirations, 5 embedded videos..., use ffprobe to confirm MP4 files are readable') and error-recovery feedback ('If live capture is blocked, prefer replacing the candidate...', 'If verification is blocked, report what was checked locally'). This matches the anchor-5 pattern of clear sequence, explicit validation, and feedback loops.

Progressive Disclosure

Sections are well-organized (Goal, Contract, Workflow, Prompt Style Rules, Library Guidance) but the skill is ~130 lines with zero reference files: the Library Guidance catalog and the lengthy Daily UI contract are content that clearly belongs in separate reference files and is inlined instead. This matches anchor 3 — some structure, but content that should be separate is inline; not 4 because there are no well-signaled references at all, and the skill exceeds the under-50-line exception.

Specificity

The description lists multiple concrete, third-person actions — 'Convert a supplied HTML page... into a screenshot-backed article', 'extract animation/interactions, create prompts, capture screenshots for each prompt, add them to an article, or commit the resulting article/assets' — covering the full workflow comprehensively. It is not below 4 because coverage has no meaningful gaps; it is not vague at any point.

Completeness

Both 'what' (convert HTML into a screenshot-backed article of reusable interaction prompts) and 'when' (an explicit 'Use when the user provides... and asks to...' clause with concrete triggers) are clearly and explicitly stated. It matches the anchor-5 example structure exactly; score 4 would apply only if the 'when' were less explicit.

Trigger Term Quality

Natural user phrases are comprehensively covered with synonyms and a concrete filename: 'HTML file, exported page, generated-page.html, or local/live reference' plus verbs users would actually say ('extract animation/interactions', 'create prompts', 'capture screenshots', 'commit'). Anchor 4 would require missing natural terms, but none are evident.

Distinctiveness Conflict Risk

The HTML-to-interaction-prompt niche with specific triggers like 'generated-page.html' is mostly distinct, but 'capture screenshots for each prompt' and 'add them to an article' carry minor overlap risk with generic screenshot or article-writing skills. Not 5 due to that residual overlap; clearly above 3 because the core trigger combination is unique.
