Quality

Content

72%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is concise and well-structured for a simple instruction-only skill, but lacks executable code examples and any verification step to confirm the loop is actually seamless.

Suggestions

Add a small copy-paste code or CSS/JS snippet demonstrating the duplicate-and-animate technique to lift actionability.

Include a brief verification step in the workflow (e.g., 'Verify the last frame aligns exactly with the first to confirm seamlessness') to add a validation checkpoint.

Optionally show a prefers-reduced-motion fallback snippet so the accessibility guidance is actionable rather than descriptive.

DimensionReasoningScore

Conciseness

The body is lean with no padding and no explanation of what a marquee is; every line (Use When, Workflow, Guardrails) earns its place, matching the 'lean and efficient; every token earns its place' anchor.

5 / 5

Actionability

Guidance is concrete ('linear transform from 0 to -50%', 'duplicate the item sequence') but provides no executable code or copy-paste example, fitting the 'some concrete guidance but incomplete; missing key details' anchor rather than the executable 4/5.

3 / 5

Workflow Clarity

Six steps are clearly sequenced, but there are no validation checkpoints or feedback loops to confirm the loop is seamless; this matches the 'steps listed but validation gaps; checkpoints missing' anchor. The skill is non-destructive so the destructive cap does not apply.

3 / 5

Progressive Disclosure

This is a simple skill under 50 lines with no bundle files, organized into clear sections (Use When, Workflow, Guardrails); per the simple-skills guideline, well-organized sections alone warrant a 5.

Description

46%Weight 40%Scale 1-5

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description clearly identifies a specific niche but is thin on capability breadth and trigger guidance. Adding a 'Use when...' clause and natural user keywords would markedly improve it.

Suggestions

Add an explicit 'Use when...' clause with natural trigger phrases (e.g., 'Use when building scrolling logos, tickers, testimonials, or infinite-scroll carousels').

Broaden capability specificity beyond a single technique, e.g. 'duplicate items, animate a track from 0 to -50%, and mask edges'.

Include synonyms users actually say ('infinite scroll', 'ticker', 'carousel', 'scrolling text') to improve trigger-term quality.

DimensionReasoningScore

Specificity

The description names the domain ('seamless infinite marquee loops') and one concrete technique ('duplicated items') with a single action ('Apply'), matching the anchor that lists 1-2 concrete actions but is not comprehensive.

3 / 5

Completeness

It states a clear 'what' (apply seamless infinite marquee loops) but lacks any 'Use when...' trigger clause, so per the missing-trigger cap it cannot exceed 3 and matches the 'clear what, when missing' anchor.

3 / 5

Trigger Term Quality

It uses technical terms ('marquee loops', 'duplicated items') but omits natural user phrases such as 'scrolling text', 'ticker', 'infinite scroll', or 'carousel', fitting the anchor for one or two generic keywords missing the natural phrases users say.

2 / 5

Distinctiveness Conflict Risk

'Seamless infinite marquee loops using duplicated items' is a specific niche with minimal overlap risk, fitting the 'mostly distinct; minor overlap risk' anchor rather than the fully comprehensive 5.
