webgl-card-effects is agent-read markdown (skill) from notque/vexjoy-agent: Standalone WebGL fragment shaders for card visual effects: holographic foil, shimmer, rarity glow..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
# WebGL Card Effects Skill ## Overview This skill adds GPU-accelerated visual effects to React card components using standalone WebGL2 fragment shaders — no Three.js, no R3F, no external library required. It targets deckbuilder games and card UIs where rarity tiers should feel visually distinct, not just differentiated by a CSS `box-shadow` value. **Scope**: Holographic foil overlays, metallic shimmer bands, rarity-driven energy pulses, and interactive tilt-shine effects mounted directly on React card components. The canonical target is `FramedCard.tsx` in a React 19 / Vite / Tailwind project with a rarity system (starter → common → uncommon → rare → legendary). **Not in scope**: 3D transformations, texture loading, post-processing pipelines, or any Three.js scene management. For those, use `threejs-builder`. **Key constraint**: Browsers cap WebGL contexts at roughly 8–16 total per page. This skill uses a single shared WebGL2 context with blit-to-2D-canvas output per card, avoiding the per-card context problem entirely. See `references/shader-integration-react.md` for the full singleton pattern. --- ## Instructions ### Phase 1: ASSESS …
