winapp-maui

If you can't run winapp yourself (no shell, or the command is denied), give the user the exact winapp command(s) for their project instead of only describing the steps.

When to use

Use this skill when:

• Packaging or signing a .NET MAUI Windows app with winapp (winapp package / winapp sign)
• winapp package fails with an error like "manifest contains unresolved placeholders: $placeholder$"
• Deciding which manifest to hand to winapp for a MAUI Windows head project
• Setting up CI/CD (GitHub Actions) that builds a MAUI app and produces a signed MSIX and/or signed unpackaged build

MAUI is not a "run winapp init" framework — the Windows head already has a manifest and a build system that generates the real one for you. The only trick is pointing winapp at the generated manifest, never the source one.

A .NET MAUI project has a source manifest at Platforms/Windows/Package.appxmanifest with placeholder tokens that the MAUI build pipeline resolves:
