Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00045 | $0.03364 |
| Opus 5 | $0.00023 | $0.01682 |
| Sonnet 5 | $0.00009 | $0.00673 |
| Haiku 4.5 | $0.00005 | $0.00336 |
Grade A, and why
swiftui-graphics scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 10d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
This is a copy
100% identical to swiftui-graphics — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 409 lines — stays where its author put it; the contents beside it link to each section on GitHub.
SwiftUI Graphics
Advanced SwiftUI visuals: Metal shaders, visual effects, Liquid Glass, Canvas. Loaded for advanced thesis (shaders, holographic, liquid-glass, distortion). Foundation:
../swiftui-motion/SKILL.mdcovers the basics. Concise rules here. Deep-dives inreferences/.
Decision Tree: Which API?
| Need | API |
|---|---|
| Pixel-level color manipulation | .colorEffect(ShaderLibrary....) |
| Pixel position / distortion | .distortionEffect(ShaderLibrary....) |
| Full layer with overlay (mix shader + bg) | .layerEffect(ShaderLibrary....) |
| View modifier with geometry context | .visualEffect { content, geometry in } |
| Custom drawing (paths, gradients) | Canvas { context, size in } |
| iOS 26+ glassmorphism | .glassEffect() / GlassEffectContainer |
| Performance dump | Canvas with .opaque(true) then export |
Default order of escalation: built-in modifiers ->
.visualEffect->Canvas-> Metal shader. Reach for shaders only when the effect is per-pixel and animated.
Metal Shaders Intro
SwiftUI binds to Metal Shading Language (MSL) via three modifiers shipped in iOS 17: .colorEffect, .distortionEffect, .layerEffect. You author a .metal file in your app target, mark functions with the [[ stitchable ]] attribute, and SwiftUI auto-generates the Swift binding via ShaderLibrary.<functionName>(...). One library per app target. Shaders run on the GPU at native resolution; arguments are passed as .float, .float2, .color, .image from Swift. iOS 17+ only; for older targets, fall back to gradients, blur, or Canvas.
The three slots differ by what data they receive:
.colorEffect: gets(position, color), returns transformed color. No neighbor sampling..distortionEffect: gets(position), returns a new sample position. Pixels move, colors do not change..layerEffect: gets(position, SwiftUI::Layer layer), returns final color. Can sample anywhere withinmaxSampleOffset. Most expensive.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

swiftui-graphics is a skill published in the GitHub repository Kenyi001/oraculo-radiohead (0 stars, last pushed 13d ago), licensed MIT. It adds 45 tokens to every session and 3,364 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to swiftui-graphics, differing in 0 lines, and is treated as a copy.
