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:

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

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)

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
