Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

What it costs to keep this loaded
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 | $0.00129 | $0.01820 |
| Opus 5.5 | $0.00052 | $0.00728 |
| Sonnet 5.5 | $0.00026 | $0.00364 |
| Haiku 4.5 | $0.00013 | $0.00182 |
Grade A, and why
uno-platform 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 1mo 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.

Uno Platform
Trigger On
- building cross-platform apps from a single C# and XAML codebase
- targeting WebAssembly, iOS, Android, macOS, Linux, and Windows simultaneously
- migrating WPF or UWP applications to cross-platform
- implementing pixel-perfect UI across all platforms
- using WinUI/UWP APIs on non-Windows platforms
Documentation
- Uno Platform Overview
- Getting Started
- Using Uno Platform with WinUI
- Platform-Specific Code
- MVUX Pattern

Platform Support
| Platform | Rendering | Notes |
|---|---|---|
| Windows | WinUI 3 | Native Windows App SDK |
| WebAssembly | Skia/Canvas | Runs in browser |
| iOS | Skia/Metal | Native iOS app |
| Android | Skia/OpenGL | Native Android app |
| macOS | Skia/Metal | Mac Catalyst or AppKit |
| Linux | Skia/X11 | GTK or Framebuffer |
Workflow
- Choose the right template — Uno Platform offers various templates for different scenarios
- Understand rendering modes — Skia vs native rendering affects performance and fidelity
- Apply MVVM or MVUX patterns — keep views dumb, logic in ViewModels
- Handle platform differences — use conditional XAML or partial classes
- Test on all target platforms — behavior varies across platforms

What ships with it
2 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.

uno-platform is a skill published in the GitHub repository managedcode/dotnet-skills (490 stars, last pushed 2d ago), licensed MIT. It adds 129 tokens to every session and 1,820 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
