animation-systems

Use when designing or implementing product-grade web motion like Stripe, Linear, Apple, and Vercel. Covers motion principles, easing/duration defaults, choreography patterns, scroll/hover interactions, performance, accessibility (reduced motion), and implementation guidance.

Quality

Content

92%

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

A well-organized, actionable, and token-efficient animation reference with a clear output workflow. Its main gap is progressive disclosure: all content lives inline in one file with no external references, and at ~184 lines some detailed sections could be offloaded to reference files.

Suggestions

Split the detailed 'Defaults' and 'Choreography patterns' sections into a references/ file (e.g. MOTION-TOKENS.md) and link to it from a leaner SKILL.md overview to enable one-level-deep progressive disclosure.

Add a small concrete code recipe (CSS transition or GSAP/Framer snippet) directly in the body so the 'Output format' step 5 has an executable anchor rather than only being described.

Consider a short validation/review checklist at the end (e.g. 'verify transform/opacity only, confirm prefers-reduced-motion branch') to make the generative workflow self-checking.

DimensionReasoningScore

Conciseness

Lean bullet-driven reference with no padding about what CSS, transforms, or animation libraries are; every section delivers skill-specific defaults and rules rather than concepts Claude already knows.

3 / 3

Actionability

Provides concrete, specific guidance — exact duration ranges (120–200ms, 400–800ms), offsets (12–24px), stagger (40–90ms), property preferences (transform/opacity), and easing choices — that is directly applicable; as an instruction skill, executable code is not required per the scoring notes.

3 / 3

Workflow Clarity

The 'Output format' section sequences the deliverable into five explicit steps (motion goals → tokens → choreography plan → implementation notes → code recipe), and the work is generative rather than destructive, so validation checkpoints are not required to reach a clear-sequence score.

3 / 3

Progressive Disclosure

Well-organized with clear section headers, but it is a single ~184-line file with no bundle files or one-level-deep references, and detailed defaults/choreography that could be split out remain inline.

Description

100%

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, concise description with an explicit 'Use when' trigger, concrete coverage enumeration, and brand-anchored distinctiveness. Third-person voice is maintained throughout.

DimensionReasoningScore

Specificity

Enumerates concrete coverage areas — 'motion principles, easing/duration defaults, choreography patterns, scroll/hover interactions, performance, accessibility (reduced motion), and implementation guidance' — paired with the concrete actions 'designing or implementing product-grade web motion'.

3 / 3

Completeness

Explicitly answers both halves: 'what' (the enumerated motion coverage) and 'when' via the opening 'Use when designing or implementing...' trigger clause.

3 / 3

Trigger Term Quality

Uses natural trigger phrasing a user would say — 'Use when designing or implementing product-grade web motion like Stripe, Linear, Apple, and Vercel' — where the named brands and 'web motion'/'reduced motion' are terms users actually invoke.

3 / 3

Distinctiveness Conflict Risk

The product-grade web-motion niche anchored to Stripe/Linear/Apple/Vercel is a clear, distinct lane unlikely to collide with unrelated skills.
