## What it does

This skill maps a project request to `dotnet new` templates, such as an API, console app, test project, or MAUI app. It suggests template short names and parameters for authentication, controllers, AOT, or a target .NET framework.

For exact options, constraints, and generated files, the agent can run `dotnet new search`, `dotnet new list`, `dotnet new <template> --help`, or a dry run. Run `dotnet new` calls one at a time because concurrent requests can conflict with the template engine's global mutex.

It does not create the project itself; use `template-instantiation` for that task. Templates including `maui`, `winui3`, `aspire-starter`, `aspire`, `func`, and `orleans` can require a workload or an extra template package. Check template availability before relying on a recommendation.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill template-discovery -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/template-discovery/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/template-discovery/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill template-discovery -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/template-discovery/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill template-discovery -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/template-discovery/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install dotnet/skills template-discovery
```

2. **Manually: put the files in place**
- File: `.github/skills/template-discovery/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill template-discovery -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/dotnet/skills --path plugins/dotnet-template-engine/skills/template-discovery
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/template-discovery/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add dotnet/skills --skill template-discovery -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/dotnet/skills/tree/HEAD/plugins/dotnet-template-engine/skills/template-discovery/SKILL.md

## When to use it
- match a project brief to a `dotnet new` template
- inspect template parameters and constraints
- preview files produced by a template
- find a package or workload for a missing template
- map authentication needs to template options

## Example prompts
- Find a `dotnet new` template for a Web API with authentication.
- Inspect the parameters for the `webapi` template before creating a project.
- Which templates fit a MAUI application?

  Helps find, inspect, and compare (at a high level) .NET project templates.

  USE FOR: finding the right dotnet new template for a task, inspecting a template's
  parameters and constraints, understanding what a template
  produces before creating a project, resolving intent like "web API with auth" to
  concrete template + parameters.
  DO NOT USE FOR: actually creating projects (use template-instantiation), authoring
  custom templates (use template-authoring), producing a detailed side-by-side comparison
  (use template-comparison), choosing cross-parameter defaults during creation
  (use template-smart-defaults), MSBuild or build issues (use dotnet-msbuild plugin),

# Template Discovery

This skill helps an agent find, inspect, and select the right `dotnet new` template for a given task using `dotnet new` CLI commands for search, listing, and parameter inspection.

## When to Use

- User asks "What templates are available for X?"
- User describes a project in natural language ("I need a web API with authentication")
- User wants to compare templates or understand parameters before creating a project
- User needs to know what a template produces (files, structure) before committing

## When Not to Use

- User wants to create a project — route to `template-instantiation` skill
- User wants to author or validate a custom template — route to `template-authoring` skill
- User wants a detailed side-by-side comparison of templates — route to `template-comparison` skill
- User wants smart cross-parameter defaults during creation — route to `template-smart-defaults` skill
- User is troubleshooting build issues — route to `dotnet-msbuild` plugin

> **Recommendation requests: answer first, confirm second. Inspection requests: inspect
> first.** For a general "which template?" question, start from the Step 1 mappings so a
> transient CLI failure cannot leave the user without an answer. When the user explicitly
> asks what is installed, requests exact options/defaults, or asks for dry-run output, run
> the relevant `dotnet new` command before writing the final answer. Never end a turn on a
> `dotnet new` call or a "let me confirm..." teaser.

> **Inspection requests require inspection.** If the user asks for installed choices,
> exact parameters/defaults, compatibility constraints, or the exact dry-run file list,
> run the corresponding `dotnet new` command. Do not replace observed data with remembered
> flags. Report a flag only when the current template's `--help` output contains it.
