winapp-troubleshoot

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:

• Diagnosing errors from winapp CLI commands
• Choosing the right command for a task
• Understanding prerequisites — what each command needs and what it produces

Common errors & solutions

For slow WinUI layout or scrolling, use the winapp-performance skill. ETW performance capture is separate from debugger output and crash analysis.
