Quality

Content

85%

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, well-organized, and clearly scoped as a single-frame template, scoring well on clarity and structure. Actionability is the weakest dimension because the SVG grain is abbreviated and no complete executable HTML example is provided.

Suggestions

Replace the "...feTurbulence..." placeholder with a complete inline SVG data-URI so the grain layer is copy-paste ready.

Include a minimal complete single-file HTML skeleton demonstrating the canvas, light-leak gradients, grain overlay, and serif type together.

DimensionReasoningScore

Conciseness

The body is lean and terse (~30 lines) with concrete values (color codes, opacity, fonts, sizes, blend modes) and no filler explaining what grain or letterbox is; every token earns its place.

3 / 3

Actionability

It gives concrete executable CSS (real radial-gradients, hex colors, mix-blend-mode, font stacks), but the SVG grain layer is abbreviated with "...feTurbulence..." and there is no complete copy-paste HTML file, leaving some guidance incomplete.

2 / 3

Workflow Clarity

This is a single-frame render (a simple single-purpose skill) with an unambiguous deliverable and clearly organized component sections, so workflow clarity scores 3 under the simple-skill exception.

3 / 3

Progressive Disclosure

The skill is under 50 lines, needs no external bundle files, and is organized into well-labeled sections (canvas, background, text, optional extras, design details), satisfying the <50-line exception for a score of 3.

Description

72%

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 is specific and distinctive with strong natural trigger terms, but it reads as a feature list without action verbs and omits an explicit "Use when…" trigger clause, which caps both specificity and completeness at 2.

Suggestions

Lead with a concrete action verb, e.g. "Render a cinematic frame with film light leaks, grain, 16:9 letterbox, and large serif type."

Add an explicit trigger clause such as "Use when the user wants a cinematic opening or chapter card with a film/light-leak look."

DimensionReasoningScore

Specificity

It names concrete visual elements ("light leaks, grain, 16:9 letterbox, and large serif type") but states them as a feature list with no action verbs, so it names the domain and specifics without comprehensively describing actions.

2 / 3

Completeness

It states the what (the visual treatments) and a use case ("for cinematic openings or chapter cards"), but lacks an explicit "Use when…" trigger clause, capping completeness at 2 per the guideline.

2 / 3

Trigger Term Quality

Terms like "film light leaks", "grain", "letterbox", "cinematic openings", and "chapter cards" are natural keywords a user requesting this style would actually say, giving good coverage.

3 / 3

Distinctiveness Conflict Risk

The cinematic light-leak frame niche is highly specific and unlikely to trigger for the wrong skill.
