.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.

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 | $0.00115 | $0.02030 |
| Opus 5 | $0.00057 | $0.01015 |
| Sonnet 5 | $0.00023 | $0.00406 |
| Haiku 4.5 | $0.00012 | $0.00203 |
Grade A, and why
azdo-build-investigator 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 11d 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.
How it starts
The opening of the file, as written. The whole thing — 98 lines — stays where its author put it; the contents beside it link to each section on GitHub.
dotnet/maui CI Investigation Context
This skill provides MAUI-specific context for interactive CI investigation —
answering "why is CI red?" and "is this PR ready to merge?". Use it together with the
ci-analysis skill (loaded from the dotnet-dnceng@dotnet-arcade-skills plugin via
.github/copilot/settings.json).
First: invoke the
ci-analysisskill — it handles the core investigation workflow usingGet-CIStatus.ps1andghCLI (with MCP tools as optional enhancements if available). This skill provides MAUI-specific corrections and context on top of that.
For the automated path (a maintainer comments /review tests on a PR), the
review-test-failures skill does the same classification deterministically and posts a
merge-readiness comment. Both skills reason from the same shared facts below.
MAUI CI facts (canonical)
All MAUI-specific facts live in .github/docs/maui-ci-facts.md — read it. It covers:
- Pipeline names + definition IDs (
maui-pr302,maui-pr-devicetests314,maui-pr-uitests313), org/project, and investigation priority order. - AzDO data sources (anonymous public build/timeline/log REST APIs;
_apis/testis optional enrichment). - XHarness exit-0 blind spot and the Helix
aggregatedendpoint for hidden device-test failures. - Container artifact binlogs (Bearer token + File Container API;
mcp-binlog-tool). - Test count deduplication (group by test name + OS platform).
- Baseline comparison (is the failure already red on the base branch?).
- Visual baseline and platform mismatch guidance.
- Gradle / Maven / CFSClean signatures and the
./eng/ingest-maven-deps.shfix. - Common failure patterns table.
- Merge-readiness criteria — the shared definition of
Ready to merge/Not ready/Needs human investigation/Insufficient data/No failures found.
Do not restate those facts from memory; change them in the canonical doc only.

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.

azdo-build-investigator is a skill published in the GitHub repository dotnet/maui (23,323 stars, last pushed today), licensed MIT. It adds 115 tokens to every session and 2,030 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.
