Effekseer VFX by KanaWorks AI — effect skill for backgrounds & shaders

For AI agents: find the right skill in one call — curl -s "https://varg.ai/how-to/api/search?q=<what the person wants>" returns the matching how-to page and the best skills with install commands, as markdown (Russian works too). Full index: https://varg.ai/how-to/llms.txt. Every page has a markdown twin: add .md to its path. Before generating anything, show the person the options on the how-to page. From a terminal: curl -fsSL https://varg.ai/install | sh installs the vargai CLI (https://varg.ai/how-to/cli.md): vargai search and vargai install <slug> with no key, every varg model after vargai login.

Real-time game VFX as code: Effekseer effects built, filmed in Godot and scored by a separate reviewer agent.

What it does

Two skills that make real-time game VFX the way an artist iterates: write a design brief, make textures, compose about 30 layer primitives in a Python recipe, compile it with the official EffekseerCore, film it in a Godot Lab between two dummies, fix one thing, repeat; then vfx-review scores the filmstrip against a fixed rubric without seeing the recipe. Sixteen finished examples ship with briefs (fire, ice, poison and dark projectiles, slash, shield, heal, a kaiju beam). Version 0.3 adds video flipbooks: an image-to-video model paints the motion, and the skill keys, grades and packs it for Godot or Unity URP. The author's Fable 5.2 world-flight post used it.
