.NET MAUI is a C# and XAML framework for building native mobile and desktop applications from one shared codebase. Developers use it to create apps for Android, iOS, iPadOS, macOS, and Windows. The catalogue entries provide skills, instructions, and agents for working with .NET MAUI.

SkillSpector: 1 finding, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Tool Misuse · line 231 Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.
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 | $0.00046 | $0.03298 |
| Opus 5.5 | $0.00018 | $0.01319 |
| Sonnet 5.5 | $0.00009 | $0.00660 |
| Haiku 4.5 | $0.00005 | $0.00330 |
Grade C, and why
run-device-tests scanned grade C with 1 finding 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.
Recursive force deletehighDestructive command
rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

Run Device Tests Skill
Build and run .NET MAUI device tests locally on iOS simulators, MacCatalyst, Android emulators, or Windows.
Platform Support
| Host OS | Supported Platforms |
|---|---|
| macOS | ios, maccatalyst, android |
| Windows | android, windows |
Tools Required
This skill uses bash together with pwsh (PowerShell 7+) to run the PowerShell scripts. Requires:
xharness- Global dotnet tool for running tests on iOS/MacCatalyst/Androiddotnet- .NET SDK with platform workloads installed- iOS/MacCatalyst: Xcode with iOS simulators
- Android: Android SDK with emulator
- Windows: Windows SDK
Dependencies
This skill uses shared infrastructure scripts:
.github/scripts/shared/Start-Emulator.ps1- Detects and boots iOS simulators / Android emulators.github/scripts/shared/shared-utils.ps1- Common utility functions
These are automatically loaded by the Run-DeviceTests.ps1 script.
When to Use
- User wants to run device tests locally
- User wants to verify iOS/MacCatalyst/Android/Windows compatibility
- User wants to test on a specific iOS version (e.g., iOS 26)
- User asks "run device tests for Controls/Core/Essentials/Graphics"
- User asks "test on iOS simulator" or "test on Android emulator"
- User asks "run device tests on MacCatalyst"
- User wants to run only specific test categories (e.g., "run Button tests")
Available Test Projects

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.

run-device-tests is a skill published in the GitHub repository dotnet/maui (23,322 stars, last pushed today), licensed MIT. It adds 46 tokens to every session and 3,298 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
