Individual skill
template-instantiation
Creates .NET projects from templates with validated parameters, smart defaults, Central Package Management adaptation, and latest NuGet version resolution. USE FOR: creating new dotnet projects, scaffolding solutions with multiple projects, installing or uninstalling template packages, creating projects that respect Directory.Packages.props (CPM), composing multi-project solutions (API + tests + library), getting latest NuGet package versions in newly created projects. DO NOT USE FOR: finding templates (use template-discovery), producing a detailed side-by-side comparison of templates (use template-comparison), authoring custom templates (use template-authoring), deciding cross-parameter defaults such as which framework to pair with native AOT or whether to keep HTTPS when auth is enabled (use template-smart-defaults), modifying existing projects or adding NuGet packages to existing projects.

# Template Instantiation
This skill creates .NET projects from templates using `dotnet new` CLI commands, with guidance for parameter validation, Central Package Management adaptation, and multi-project composition.
> **Match the workspace, then stop.** The highest-value move is aligning the new project with the repo it lands in: detect **CPM** (`Directory.Packages.props`) and the **target framework** used by neighbouring `.csproj` files, and mirror both. **Treat the discovered target framework as an explicit choice** — pass it as `--framework` so `template-smart-defaults` won't override it; deviate only when it's incompatible with a requested feature (then flag the conflict). Do this in as few steps as possible — a `--dry-run`, the create, and one `dotnet build` to confirm is usually enough. Extra exploratory turns add cost without improving the result.
> **Perform the requested creation.** Do not return only a plan or statement of intent.
> Run state-dependent commands sequentially: inspect, dry-run, create, then build. Never
> launch create and build in parallel; a build-before-create race produces a false failure.
| Situation | Required action |
|-----------|-----------------|
| Simple standalone project | inspect only the requested template, create at the exact path, then build |
| Existing neighboring projects | read their TFMs first and pass the matching supported `--framework` explicitly |
