# install-atk

This skill checks that the M365 Agents Toolkit CLI runs and installs the VS Code extension. Handy when ATK has to be set up on a machine.

## What it does

One job: get M365 Agents Toolkit (ATK) installed or updated, both the CLI and the VS Code extension. Ask for it in plain words — "install atk", "update agents toolkit" — and the skill works out the scope: everything, CLI only, or just the VSIX.

Nothing gets installed globally. Every call goes through `npx -y --package @microsoft/m365agentstoolkit-cli atk`, so the first run pulls the current package and later runs reuse the cache. The check itself is `npx -y --package @microsoft/m365agentstoolkit-cli atk --version`. For the editor side the skill runs `code --install-extension TeamsDevApp.ms-teams-vscode-extension`.

Before touching `atk`, it exports `ATK_CLI_SKILL=true` for the session, which tags the CLI calls as skill-initiated. A broken Node.js 18+ or npm setup makes the verification step fail, so sort that out first. Failures are reported instead of swallowed.

## Requirements
- Works with: Azure

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add microsoft/skills --skill install-atk -a claude-code
```

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

### Codex

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

### Cursor

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

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install microsoft/skills install-atk
```

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

### Gemini CLI

**Platform CLI**
```bash
gemini skills install https://github.com/microsoft/skills --path .github/plugins/microsoft-365-agents-toolkit/skills/install-atk
```

### Windsurf (Devin Desktop)

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

### 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/microsoft/skills/tree/HEAD/.github/plugins/microsoft-365-agents-toolkit/skills/install-atk/SKILL.md

## When to use it
- install the M365 Agents Toolkit CLI without a global package
- update the ATK extension inside VS Code
- confirm which ATK CLI version the session can reach
- set up ATK from scratch on a fresh machine
- find out why the `atk` command will not start

## Example prompts
- Install ATK
- Update the ATK VS Code extension
- Check whether the ATK CLI works

# Install ATK

Install or update the M365 Agents Toolkit (ATK) CLI and/or VS Code extension.

## Telemetry Tagging

Before running any `atk` CLI commands, set the session environment variable so all CLI invocations are tagged as skill-initiated:
```bash
export ATK_CLI_SKILL=true
```
Run this once at the start of the session. All subsequent `atk` commands in the same terminal will inherit it.

## Triggers

This skill activates when the user asks to:
- Install or update ATK / Agents Toolkit / the toolkit
- Install or update the ATK CLI
- Install or update the ATK VS Code extension / VSIX
- Set up ATK / get started with ATK

## Behavior

ATK CLI commands use `npx -y --package @microsoft/m365agentstoolkit-cli atk` which automatically downloads and runs the latest version — no global installation is needed.

When triggered, determine what the user wants:

| User intent | Action |
|-------------|--------|
| Install/update **everything** or just "ATK" | Verify CLI works + install VSIX |
| Install/update **CLI** only | Verify CLI works (npx handles it automatically) |
| Install/update **extension** / **VSIX** only | Install VSIX only |
| Ambiguous | Verify CLI works + install VSIX |

## Commands

### Step 1: Verify ATK CLI works

```bash
npx -y --package @microsoft/m365agentstoolkit-cli atk --version
```

- **If this succeeds** (prints a version): ATK CLI is available. The `npx` prefix automatically downloads the latest package on first use and caches it for subsequent runs.
- **If this fails**: Check that Node.js 18+ and npm are installed. The `npx` command requires a working Node.js environment.

### Step 2: ATK VS Code Extension (if requested)

```bash
code --install-extension TeamsDevApp.ms-teams-vscode-extension
```

## Execution

1. **Verify** ATK CLI works by running `npx -y --package @microsoft/m365agentstoolkit-cli atk --version`
2. Report the result (version number / failure)
3. Install VS Code extension if requested
4. Explain that all ATK commands use the `npx -y --package @microsoft/m365agentstoolkit-cli atk` prefix — no global install needed

## Safety Rules

- **MUST NOT** skip errors — report failures clearly to the user
- **MUST** use the exact package names and extension IDs above — do not substitute with other names or links
