visual-style

Create, extract, and apply portable visual design systems via visual-style.md files. Use when: (1) Creating a visual-style.md design system from scratch, (2) Extracting a visual style from a website URL, video, or PDF brand guide, (3) Applying a visual style to HeyGen videos, HTML slides, Figma, or paper.design, (4) Browsing the gallery of pre-built visual styles (Swiss, Saul Bass, Game Boy, etc.), (5) User mentions "visual style", "design system", "brand style", or "style guide", (6) Styling a HeyGen video with a consistent design language.

Content

78%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 well-structured overview that routes each of its four modes to concrete, existing reference files with clear navigation — exemplary progressive disclosure. The workflows and guidance are concrete but stop just short of fully self-contained: validation is lightweight without a feedback loop, and a few small redundancies could be trimmed.

Suggestions

Give the Extract workflow's "Validate" step a concrete check (e.g., the list of required fields or a pointer to the exact section of spec.md) and add a brief fix-and-retry loop so it functions as a real checkpoint.

Remove the duplicated "style_prompt_full is king" guidance and the repeated template links by keeping each fact in exactly one section (Format Quick Reference and Templates & Spec respectively).

Expand the required-fields YAML skeleton slightly or point to the minimal template inline for the Create workflow's Generate step, so the body's format guidance is complete without opening spec.md.

DimensionReasoningScore

Conciseness

The body is efficient — tables, short numbered steps, no explanations of concepts Claude already knows — but has minor trimmable redundancy: "style_prompt_full is king" appears both in Format Quick Reference and Best Practices, and the template links in the Create workflow are repeated verbatim in the Templates & Spec section. This fits the level-4 anchor (efficient, minor instances that could be trimmed) rather than the every-token-earns-its-place level 5.

4 / 5

Actionability

Guidance is mostly executable for an instruction-only skill: numbered per-mode workflows, a batched question list, a YAML required-fields skeleton, and connector/extractor tables mapping each case to a specific file. Minor gaps keep it below level 5: the YAML snippet is partial (full field spec deferred to spec.md) and the Extract "Validate" step gives no concrete check to run.

4 / 5

Workflow Clarity

All four modes (Create, Extract, Apply, Gallery) have clearly sequenced numbered steps, and validation appears in the Extract workflow ("Validate — Ensure all required fields are present") plus a preview step in Create. It sits at level 4 rather than 5 because there is no fix-and-retry feedback loop and validation criteria are implicit; the destructive/batch cap does not apply since these are non-destructive file-generation operations.

4 / 5

Progressive Disclosure

The body is a true overview — quick-reference mode table, concise workflows, format summary — with all detailed material pushed one level deep into clearly signaled reference files (connectors, extractors, gallery, templates, spec.md), each presented in a use-case table. Every referenced path resolves to a real file in the bundle, and nothing that belongs in a separate file is inlined, matching the level-5 anchor.

Description

88%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 strong description that clearly states what the skill does and gives six explicit trigger conditions with natural user phrases. Its only weaknesses are a few missing common synonyms for trigger terms and slight overlap risk from the broad phrases "design system" and "brand style".

DimensionReasoningScore

Specificity

"Create, extract, and apply portable visual design systems via visual-style.md files" names the domain and enumerates multiple concrete actions — creating from scratch, extracting from a website URL, video, or PDF brand guide, applying to HeyGen videos, HTML slides, Figma, or paper.design, and browsing a pre-built gallery. Coverage of the skill's modes is comprehensive, matching the level-5 anchor rather than the minor-gaps level-4 anchor.

5 / 5

Completeness

The description explicitly answers both questions: the "what" ("Create, extract, and apply portable visual design systems via visual-style.md files") and the "when" via a six-item "Use when:" list with concrete trigger phrases, including direct user-mention terms. This matches the level-5 anchor exactly.

5 / 5

Trigger Term Quality

Explicit user-mention triggers include "visual style", "design system", "brand style", "style guide", and the file name visual-style.md, which are natural phrases. However, a few common synonyms users would plausibly say — "aesthetic", "theme", "look and feel", "palette" — are missing, fitting the level-4 anchor (good coverage, a few natural terms missing) rather than comprehensive level 5.

4 / 5

Distinctiveness Conflict Risk

The niche is clear — portable visual-style.md files with named connectors (HeyGen, Figma, paper.design, HTML slides) — but the trigger terms "design system", "brand style", and "style guide" carry minor overlap risk with generic branding or design-guideline skills, fitting the level-4 anchor (mostly distinct, minor overlap with closely related skills).
