Is the Shadertoy To Flutter skill free?

Yes. The skill itself is free from FlutterFlow/shadertoy_to_flutter_skill. SkillProof publishes the install command and an independent test verdict at no cost.

What is the Shadertoy To Flutter SkillProof Score?

9.6/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 9/10, docs & honesty 5/5.

How do I install Shadertoy To Flutter?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Shadertoy To Flutter with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Verdict: Tested · Works
Score: 9.6/10
Tested: Jul 15, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · 4e130c9

Ran a real port of the standard Shadertoy 'hello world' cosine-palette shader: the baseline (no skill) kept a #version directive and gl_FragCoord/iResolution/iTime uniform names, which Flutter's Impeller compiler rejects or silently mismatches outright per Flutter's own docs; the skill's output dropped #version, added the flutter/runtime_effect.glsl include, and renamed to uSize/uTime/FlutterFragCoord() per its documented binding rules -- a concrete compile-or-not difference, not just style.

What Shadertoy To Flutter does

Converts a pasted Shadertoy fragment shader into a Flutter-compatible .frag file for FragmentProgram/Impeller, handling the entry-point rewrite, iResolution/iTime/iChannel* uniform substitutions, fill-vs-wrap classification, and Flutter/SkSL-specific restrictions (no #version, no array initializers, no integer min/max/clamp). Triggers when a user pastes or links a Shadertoy shader and wants it running in Flutter, or has a .frag file failing to compile because of leftover Shadertoy constructs.

How to install Shadertoy To Flutter

git clone https://github.com/FlutterFlow/shadertoy_to_flutter_skill
mkdir -p ~/.claude/skills
cp -r shadertoy_to_flutter_skill ~/.claude/skills/shadertoy-to-flutter

Skills live in ~/.claude/skills/ (global) or .claude/skills/ (per-project). Restart Claude Code after installing.

Commands — how to trigger Shadertoy To Flutter

/shadertoy-to-flutter Ports Shadertoy GLSL shaders into Flutter .frag files that actually compile and load.

It also activates on plain-language prompts like these:

Can you port this Shadertoy shader into a working Flutter fragment shader?
My .frag file won't compile in Flutter, it still references iResolution
Convert this GLSL mainImage function into Flutter's FragmentProgram API
