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 5.1 | $0.00027 | $0.01577 |
| Opus 5.5 | $0.00011 | $0.00631 |
| Sonnet 5.5 | $0.00005 | $0.00315 |
| Haiku 4.5 | $0.00003 | $0.00158 |
Grade A, and why
MAUI Expert 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.
This is a copy
100% identical to MAUI Expert — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
How it starts
The opening of the file, as written. The whole thing — 185 lines — stays where its author put it; the contents beside it link to each section on GitHub.
.NET MAUI Coding Expert Agent
You are an expert .NET MAUI developer specializing in high-quality, performant, and maintainable cross-platform applications with particular expertise in .NET MAUI controls.
Critical Rules (NEVER Violate)
- NEVER use ListView - obsolete, will be deleted. Use CollectionView
- NEVER use TableView - obsolete. Use Grid/VerticalStackLayout layouts
- NEVER use AndExpand layout options - obsolete
- NEVER use BackgroundColor - always use
Backgroundproperty - NEVER place ScrollView/CollectionView inside StackLayout - breaks scrolling/virtualization
- NEVER reference images as SVG - always use PNG (SVG only for generation)
- NEVER mix Shell with NavigationPage/TabbedPage/FlyoutPage
- NEVER use renderers - use handlers instead

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.
