Quality

Content

100%

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

The body is a tight, well-structured design specification with concrete copy-paste CSS values and exact dimensions, clear single-purpose organization, and no unnecessary concept explanations or nested references.

Dimension	Reasoning	Score
Conciseness	The body is a lean, dense design spec with concrete values and no padding explaining concepts Claude already knows; every section earns its tokens.	3 / 3
Actionability	Provides exact copy-paste-ready CSS (e.g. 'background: rgba(245,245,247,0.78)' and 'backdrop-filter: blur(40px) saturate(180%)') and precise pixel dimensions; as an instruction-only template spec the guidance is concrete and actionable.	3 / 3
Workflow Clarity	A single unambiguous task organized into clear sections (canvas, structure, content, fonts, optional additions, design details), with no destructive or batch operation requiring validation checkpoints.	3 / 3
Progressive Disclosure	Under 50 lines with no need for external references and well-organized sections, satisfying the simple-skill allowance for a top progressive-disclosure score.	3 / 3
	Total	12 / 12 Passed

Description

57%

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 concretely names the output and its use contexts and occupies a distinct niche, but it lacks an explicit 'Use when…' trigger clause and natural keyword variations, leaving completeness and trigger coverage at the mid level.

Suggestions

Add an explicit trigger clause, e.g. 'Use when creating a macOS-style notification banner for a video overlay, product teaser, or social graphic.'

Expand natural trigger terms to include variations users might say, such as 'alert', 'push notification', 'notification overlay', or 'Big Sur banner'.

Lead with the concrete action verb (e.g. 'Renders…' or 'Builds…') to sharpen the capability statement.

Dimension	Reasoning	Score
Specificity	Names the domain ('macOS notification banner') and concrete output elements ('app icon, title, and body') plus use contexts, but describes a single rendered output rather than enumerating multiple distinct actions.	2 / 3
Completeness	The 'what' is clear (a realistic notification banner with icon/title/body), but the 'when' is only implied via 'suited to' with no explicit 'Use when…' trigger clause, which caps completeness at 2.	2 / 3
Trigger Term Quality	'macOS notification banner', 'video overlays', and 'product teasers' are natural terms a user would say, but common variations like 'alert', 'push notification', or 'banner overlay' are missing.	2 / 3
Distinctiveness Conflict Risk	'macOS notification banner' is a clear, narrow niche with distinct triggers that is unlikely to collide with other skills.	3 / 3
