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.

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 | $0.00121 | $0.02340 |
| Opus 5 | $0.00060 | $0.01170 |
| Sonnet 5 | $0.00024 | $0.00468 |
| Haiku 4.5 | $0.00012 | $0.00234 |
Grade A, and why
maui 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 2d 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.

.NET MAUI
Trigger On
- working on cross-platform mobile or desktop UI in .NET MAUI
- integrating device capabilities, navigation, or platform-specific code
- migrating Xamarin.Forms or aligning a shared codebase across targets
- implementing MVVM patterns in mobile apps

Platform Targets
| Platform | Build Host | Notes |
|---|---|---|
| Android | Windows/Mac | Emulator or device |
| iOS | Mac only | Requires Xcode |
| macOS | Mac only | Catalyst |
| Windows | Windows | WinUI 3 |
Workflow
- Confirm target platforms — behavior differs across Android, iOS, Mac, Windows
- Separate shared UI and platform code — use handlers and DI
- Follow MVVM pattern — keep views dumb, logic in ViewModels
- Handle lifecycle and permissions — platform contracts need testing
- Test on real devices — emulators don't catch everything
Current Upstream Notes
.NET MAUI10.0.100is a broad quality release for the 10.0 line. It fixes Android WebView gestures insideSwipeView, RenderThread crashes and syntheticabout:blankhistory; iOS WebView file/reload behavior; Shell regressions; XAML source-generation AOT paths; adaptive-trigger leaks; shared/customPlatformsmappings; status-bar contrast, window metrics, and SafeArea behavior.- After upgrading MAUI packages, smoke-test grouped and virtualized

.NET MAUILearn overview fornet-maui-10.0still frames the platform around a shared single-project app, native API access, handlers, and optional Blazor Hybrid UI. Verify each target platform rather than treating shared code as identical runtime behavior.
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.

maui is a skill published in the GitHub repository managedcode/dotnet-skills (477 stars, last pushed 2d ago), licensed MIT. It adds 121 tokens to every session and 2,340 once invoked, about $0.0006 per session on Opus 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.
