What is maui-labs packaging.instructions.md?

Build and packaging instructions for the dotnet/maui-labs repository, including NuGet package management and .NET build infrastructure.

They help add NuGet packages, manage versions, create packable projects, and work with Arcade SDK build scripts and Dependency Flow.

They explain where package versions and build settings belong, while identifying generated files that should not be edited.

Token cost

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	$0.01195	$0.01195
Opus 5.5	$0.00478	$0.00478
Sonnet 5.5	$0.00239	$0.00239
Haiku 4.5	$0.00120	$0.00120

Security

Grade A, and why

maui-labs packaging.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 2mo 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.

Packaging and Build Infrastructure

Arcade SDK

This repo uses the Microsoft.DotNet.Arcade.Sdk for build infrastructure. Key rules:

Never modify files in eng/common/ — they are auto-generated and overwritten by Dependency Flow updates
Arcade version is pinned in global.json under msbuild-sdks
CI scripts: eng/common/cibuild.sh (macOS/Linux) and eng\common\cibuild.cmd (Windows)

Central Package Management

All NuGet package versions are defined in Directory.Packages.props at the repo root.

.csproj files reference packages without versions: <PackageReference Include="xunit" />
To add a new dependency: add <PackageVersion Include="Package.Name" Version="X.Y.Z" /> to Directory.Packages.props
To override a version in a specific project: use VersionOverride="X.Y.Z" on the PackageReference
MAUI and runtime package versions flow via Dependency Flow (Maestro/DARC) and are defined in eng/Versions.props

Adding a New NuGet Package

Create the project in src/{Product}/:

<Project Sdk="Microsoft.NET.Sdk">
  <PropertyGroup>
    <TargetFramework>net10.0</TargetFramework>
    <IsPackable>true</IsPackable>
    <IsShipping>true</IsShipping>
    <PackageId>Microsoft.Maui.DevFlow.NewPackage</PackageId>
    <Description>What this package does</Description>
  </PropertyGroup>
</Project>

Set IsPackable and IsShipping to true (defaults are false in Directory.Build.props)
For CLI tools, also set PackAsTool=true and ToolCommandName=your-command
Add any new third-party dependencies to Directory.Packages.props

Add signing entries in eng/Signing.props for third-party DLLs:

<FileSignInfo Include="ThirdParty.dll" CertificateName="3PartySHA2" />

Add the project to the solution: MauiLabs.slnx and the product's .slnf
Add to DevFlow.slnf if it should be built by CI
Check the product's build job in eng/pipelines/devflow-official.yml. Add the project to the exact .slnf or .slnx used by that job; it may be narrower than the product's main solution.
Check the product's NuGet.org publish stage in eng/pipelines/devflow-official.yml. Ensure its Copy-Item package glob matches the new <PackageId>.

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.
