# Template Authoring This skill helps an agent create and validate custom `dotnet new` templates. It guides bootstrapping templates from existing projects and validates `template.json` files for authoring issues before publishing. ## When to Use - User wants to create a reusable template from an existing .csproj - User wants to validate a template.json for correctness - User is setting up `.template.config/template.json` from scratch - User wants to package a template for NuGet distribution ## When Not to Use - User wants to find or use existing templates — route to `template-discovery` or `template-instantiation` - User has MSBuild issues unrelated to template authoring — route to `dotnet-msbuild` plugin ## Inputs | Input | Required | Description | |-------|----------|-------------| | Source project path | For creation | Path to the .csproj to use as template source | | template.json path | For validation | Path to an existing template.json to validate | | Template name | For creation | Human-readable name for the template | | Short name | Recommended | Short name for `dotnet new <shortname>` usage | ## Workflow ### Step 1: Bootstrap from existing project Analyze the source `.csproj` and create a `.template.config/template.json`: 1. Create `.template.config` directory next to the project 2. Generate `template.json` with `identity` (reverse-DNS), `name`, `shortName`, `sourceName` (project name for replacement), `classifications`, and `tags` 3. Preserve from source:...
