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 | $0.00483 | $0.00483 |
| Opus 5 | $0.00242 | $0.00242 |
| Sonnet 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 4d 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 (23,317 stars, last pushed 4d ago), licensed MIT. It adds 483 tokens to every session, about $0.0024 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.
