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:
Commands
Step 1: Verify ATK CLI works
