Lean and efficient: scoped rules, executable code, and terse tuning/taste/avoid/checks lists with no explanation of concepts Claude already knows; every token earns its place.

Provides complete, executable Three.js shaders, a geometry builder, an init function with cleanup, plus HTML/CSS and a concrete invocation with real option values; copy-paste ready.

Single render task sequenced clearly (HTML/CSS -> shader -> recipe -> tuning) with a 'Quick Checks' validation checklist (sphere/ring distinct, reduced-motion still, full cleanup); no destructive/batch operation requiring a cap.

Self-contained skill with no bundle files; all content is inline yet well-organized into clearly navigable sections with no nested references.

Names the concrete deliverables ("dense luminous spherical core and thinner orbital ring or flattened disc") but lists one composite action rather than multiple distinct actions, fitting the score-2 anchor; not score-3 because it is not a comprehensive multi-action list.

Explicitly answers both what ("Create a globe-like 3D particle visualization...") and when ("Use when a design needs..."), matching the score-3 anchor with explicit triggers.

Covers natural terms a user would say ("planetary, orbital, synthesized data-globe effect", "WebGL/Three.js particles", "generic starfields") with good variation; not score-2 because the keyword coverage is broad and includes discriminators.

Clear niche (real WebGL/Three.js globe particles) with distinct triggers plus negative anti-triggers ("not generic starfields or full page layout changes"), unlikely to conflict with other skills.
