Quality

Content

92%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.

A lean, highly actionable single-frame template spec with concrete values everywhere and explicit constraints; the only gap is the absence of one assembled HTML example. Structure and token efficiency are exemplary for a skill of this scope.

DimensionReasoningScore

Conciseness

Pure parameter values throughout — "1920×800, 上下黑边各 140px", "opacity 14%, mix-blend-mode: overlay", "5-8vw, weight 500 italic" — with zero padding and no explanation of concepts Claude already knows. Matches anchor 5: every token earns its place.

5 / 5

Actionability

Highly concrete, largely copy-pasteable guidance (exact gradients like `radial-gradient(ellipse at top right, #ffb547 0%, transparent 50%)`, named fonts, sizes, and even a CJK-italic fallback), but no assembled end-to-end HTML example of the finished frame. Matches anchor 4 (minor gaps), short of anchor 5's fully copy-paste-ready common-case example.

4 / 5

Workflow Clarity

Single-purpose skill producing one frame; the section order (canvas → background → type → optional extras → constraints) is an unambiguous build sequence with explicit hard rules ("严禁蓝紫漏光/emoji", "必须用用户提供的标题") and a reduced-motion guard. Per the simple-skill exception, an unambiguous single action scores 5.

5 / 5

Progressive Disclosure

The body is under 50 lines, well-organized into labeled sections, and needs no external references (none exist in the bundle). The rubric's guideline explicitly scores this case 5 with just well-organized sections.

Description

70%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.

A specific, distinct description with good natural trigger terms, but it omits an explicit "Use when..." clause, capping completeness at 3. Adding explicit trigger guidance and a couple of common synonyms would lift the two 4s.

Suggestions

Add an explicit trigger clause, e.g. "Use when the user asks for a cinematic opening, chapter card, title card, or film-style intro frame for a video."

Include common synonyms and file/format terms users naturally say (e.g. "title card", "movie intro", "video opening", "film look", "1920×1080") to round out trigger-term coverage.

Convert the feature inventory into action phrasing (e.g. "Creates cinematic opening frames with film light leaks, 35mm grain, and 2.39:1 letterbox typography") so the capability statement reads as what the skill does.

DimensionReasoningScore

Specificity

Lists several concrete elements ("Film light leaks, grain, 16:9 letterbox, and large serif type") with specific parameters, but it is a feature inventory rather than a list of actions, leaving minor gaps in capability coverage. It exceeds anchor 3 (only 1-2 concrete actions) but is not the comprehensive action coverage of anchor 5.

4 / 5

Completeness

The "what" is clear (leaks, grain, letterbox, serif type), but "when" appears only as the weak purpose clause "for cinematic openings or chapter cards" with no explicit "Use when..." trigger guidance, which the guidelines cap at 3. Not score 4 because the trigger situation is only implied, not explicitly stated.

3 / 5

Trigger Term Quality

Good natural terms users would say — "cinematic openings", "chapter cards", "film", "light leaks", "letterbox", "grain" — but misses common synonyms and variations such as "title card", "movie intro", or "video opening". Better than anchor 3 (missing common variations are only a few), short of anchor 5's comprehensive synonym coverage.

4 / 5

Distinctiveness Conflict Risk

A clear niche with distinct triggers — the light-leak + letterbox + serif-type signature and "cinematic openings or chapter cards" purpose are unlikely to fire for a sibling skill. Matches anchor 5; anchor 4 would apply only if a closely related skill could plausibly collide on these triggers.
