Template Validation

This skill helps validate custom dotnet new templates for correctness before publishing. It encodes the validation rules that catch common authoring mistakes — issues that cause templates to silently fail, produce broken projects, or not appear in dotnet new list.

When to Use

• User asks to check or validate a template.json file
• User reports "my template doesn't show up after installing"
• User wants to review a template before packaging and publishing to NuGet
• User encounters unexpected behavior from a custom template

When Not to Use

• User wants to find or use existing templates — route to template-discovery
• User wants to create a project — route to template-instantiation
• User wants to create a template from an existing project — route to template-authoring
