Quality

Content

57%

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 well-structured, mostly lean instruction skill with concrete tokens and a clear output structure, but it lacks executable examples and explicit validation checkpoints in its workflow. Tightening the Brand paragraph and adding a worked example would lift the weaker dimensions.

Suggestions

Add one concrete worked example of a generated component guideline so the abstract rules become copy-paste ready.

Insert an explicit validation/feedback checkpoint into the authoring workflow (e.g., verify each rule maps to a token or threshold, fix and re-check).

Trim the generic prose in the 'Brand' section to keep the description token-lean.

DimensionReasoningScore

Conciseness

The body is mostly efficient bullet-listed guidance with no tutoring of concepts Claude already knows, but the 'Brand' paragraph includes generic filler ('offering a clean, user-friendly interface that adheres to modern web standards') that could be trimmed.

2 / 3

Actionability

It gives specific tokens (e.g., '#F2673C'), spacing scale, required states, and a QA checklist, but guidance stays abstract ('Define required states', 'State spacing... explicitly') without a worked, copy-paste example of a generated guideline.

2 / 3

Workflow Clarity

A clear six-step 'Guideline Authoring Workflow' with a 'Required Output Structure' and 'Quality Gates' is present, but there are no explicit validation checkpoints or feedback loops to catch errors during guideline generation.

2 / 3

Progressive Disclosure

The skill is compact and single-purpose with no external bundle files, and content is organized into well-labeled sections, satisfying the under-50-lines exception for progressive disclosure.

Description

17%

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 characterizes the flat aesthetic but does not describe what the skill does or when to invoke it, missing any explicit trigger guidance. It reads as a style definition rather than a capability statement.

Suggestions

State the concrete action the skill performs (e.g., 'Authors Flat design-system guidelines') instead of only describing the visual style.

Add a 'Use when...' clause with natural trigger terms like 'flat design', 'design system', or 'brand style guidelines'.

Include third-person capability verbs (e.g., 'Generates', 'Defines') so the description reads as a skill, not an aesthetic glossary entry.

DimensionReasoningScore

Specificity

The description names the domain and attributes ('Two-dimensional minimalist style with vibrant colors, clean typography, and no 3D effects') but lists no concrete actions the skill performs, so it sits at the lower end of 'names domain and some actions'.

2 / 3

Completeness

It states what the style is but never answers 'when should Claude use it' — there is no 'Use when...' clause, and the 'what' describes an aesthetic rather than a capability, so both halves are weak.

1 / 3

Trigger Term Quality

It lacks natural trigger terms a user would say ('flat design', 'design system', 'brand colors'); phrasing like 'Two-dimensional minimalist style' reads as technical/generic rather than user-spoken keywords.

1 / 3

Distinctiveness Conflict Risk

The phrasing is tied to a flat-design niche but is generic enough to overlap with other design/style skills, so it is somewhat specific but not clearly distinguishable.
