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, opinionated, implementation-focused authoring guide with concrete tokens, an explicit workflow, and a required output structure. It is well-organized and free of the concept-padding the rubric penalizes.

DimensionReasoningScore

Conciseness

The body is lean and bullet-driven, assumes Claude's competence, and avoids explaining concepts Claude already knows; every section earns its place.

3 / 3

Actionability

Concrete tokens (hex values, type/spacing scales), an explicit required-states list, do/don't rules, and a required output structure give copy-ready, specific guidance for an instruction-only skill.

3 / 3

Workflow Clarity

The 'Guideline Authoring Workflow' is a clear 6-step numbered sequence paired with a required output structure; no destructive or batch operations are involved, so missing validation checkpoints are not penalized.

3 / 3

Progressive Disclosure

The content is well-organized into clearly labeled sections in a single file with no need for external references, satisfying the simple-skill exception for progressive disclosure.

Description

22%

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 paints a vivid aesthetic picture but fails to state the skill's function or when to invoke it, leaving Claude without actionable triggers. It reads as a style tagline rather than a capability statement.

Suggestions

Lead with the skill's action, e.g. 'Authors implementation-ready design-system guidelines for a hand-drawn Sketch look-and-feel.'

Add an explicit trigger clause: 'Use when creating or applying Sketch-style design-system guidance, hand-drawn UI themes, or warm-paper pencil-illustration aesthetics.'

Include domain keywords users would actually say (design system, UI styling, brand tokens) alongside the aesthetic terms.

DimensionReasoningScore

Specificity

The description only lists visual adjectives ('friendly, hand-drawn sketch interface', 'soft teal brand accents', 'rounded pill controls') and names no concrete actions or capabilities, matching the vague/abstract anchor.

1 / 3

Completeness

It describes the look but not what the skill does, and there is no 'Use when...' trigger clause, so neither 'what' nor 'when' is adequately answered.

1 / 3

Trigger Term Quality

Terms like 'sketch', 'hand-drawn', and 'pencil illustrations' are natural, but common variations and core terms a user would say ('design system', 'brand', 'UI styling') are missing, so coverage is partial.

2 / 3

Distinctiveness Conflict Risk

The aesthetic niche is fairly distinctive, but as a design-system skill with no explicit triggers it could still overlap with sibling styling skills.
