.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.

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 | $0.00483 | $0.00483 |
| Opus 5.5 | $0.00193 | $0.00193 |
| Sonnet 5.5 | $0.00097 | $0.00097 |
| Haiku 4.5 | $0.00048 | $0.00048 |
Grade A, and why
maui safe-area-ios.instructions.md 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.
What it actually says
Safe Area Guidelines (iOS/macCatalyst)
Platform Differences
| macOS 14/15 | macOS 26+ | |
|---|---|---|
| Title bar inset | ~28px | ~0px |
| Used in CI | ✅ | ❌ |
Local macOS 26+ testing does NOT validate CI behavior. Fixes must pass CI on macOS 14/15.
| Platform | UseSafeArea default |
|---|---|
| iOS | false |
| macCatalyst | true |
Architecture (PR #34024)
IsParentHandlingSafeArea — before applying adjustments, MauiView/MauiScrollView walk ancestors to check if any ancestor handles the same edges. If so, descendant skips (avoids double-padding). Edge-aware: parent handling Top does not block child handling Bottom. Result cached in bool? _parentHandlesSafeArea; cleared on SafeAreaInsetsDidChange, InvalidateSafeArea, MovedToWindow. AppliesSafeAreaAdjustments is internal for cross-type ancestor checks.
EqualsAtPixelLevel — safe area compared at device-pixel resolution to absorb sub-pixel animation noise (0.0000001pt during TranslateToAsync), preventing oscillation loops (#32586, #33934).
Anti-Patterns
❌ Window Guard — comparing Window.SafeAreaInsets to filter callbacks blocks legitimate updates. On macCatalyst + custom TitleBar, WindowViewController pushes content down, changing the view's SafeAreaInsets without changing the window's. Caused 28px CI shift (macOS 14/15 only). Never gate per-view callbacks on window-level insets.
❌ Semantic mismatch — _safeArea is filtered by GetSafeAreaForEdge (zeroes edges per SafeAreaRegions); raw UIView.SafeAreaInsets includes all edges. Never compare them — compare raw-to-raw or adjusted-to-adjusted.
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 safe-area-ios.instructions.md is an instructions file published in the GitHub repository dotnet/maui (23,322 stars, last pushed today), licensed MIT. It adds 483 tokens to every session, about $0.0019 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.
