gsap-performance

Official GSAP skill for performance — prefer transforms, avoid layout thrashing, will-change, batching. Use when optimizing GSAP animations, reducing jank, or when the user asks about animation performance, FPS, or smooth 60fps.

Quality

Content

72%

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 performance guide with executable code and clear sections. Its main weakness is redundancy from restating the same guidance across three sections, and the absence of any workflow sequence given its best-practices (non-procedural) nature.

Suggestions

Collapse the 'Best practices' and 'Do Not' recaps into the relevant technique sections to remove the triple restatement of transform/opacity, will-change, stagger, quickTo, and cleanup guidance.

Since this is guidance rather than a workflow, either reframe a representative optimization task (e.g. diagnose-and-fix jank) as a short sequenced checklist, or keep it explicitly framed as a reference so workflow_clarity expectations are clear.

Consider a brief 'Quick reference' table mapping symptom→fix (jank on scroll → pin/scrub tuning; jank on many elements → stagger/virtualize) to make the actionable mapping scannable without repeating prose.

DimensionReasoningScore

Conciseness

The body is lean and free of concept-explanation padding, but the core guidance (transform/opacity, will-change, stagger, quickTo, cleanup) is restated across 'Prefer Transform and Opacity', 'Best practices', and 'Do Not', which could be tightened.

2 / 3

Actionability

Provides fully executable examples — 'will-change: transform;' and a complete gsap.quickTo() snippet with an event listener — plus specific property names and ✅/❌ lists that are copy-paste ready.

3 / 3

Workflow Clarity

This is a best-practices collection with no multi-step process or validation checkpoints, and it is not a single unambiguous-action skill that the score-3 carve-out covers; the content is organized but lacks workflow sequencing.

2 / 3

Progressive Disclosure

A self-contained single file with well-organized section headers and no nested or dangling references; nothing here needs to be split out into separate bundle files.

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 concise, well-targeted description that states concrete capabilities, includes an explicit Use-when trigger clause with natural user phrasing, and occupies a clear niche. It hits the top anchor on every dimension.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'prefer transforms, avoid layout thrashing, will-change, batching' — matching the score-3 anchor of multiple specific concrete actions rather than a single vague domain.

3 / 3

Completeness

Explicitly states both what it does (GSAP performance techniques) and when to use it via an explicit 'Use when...' clause, satisfying both halves of the completeness anchor.

3 / 3

Trigger Term Quality

Covers natural user phrasing — 'optimizing GSAP animations, reducing jank... animation performance, FPS, or smooth 60fps' — with strong coverage of terms users actually say.

3 / 3

Distinctiveness Conflict Risk

'Official GSAP skill for performance' carves a clear niche with distinct GSAP-animation-performance triggers unlikely to fire for unrelated skills.
