The Endor Labs Agent Kit installs into Antigravity CLI as a plugin, adding the Endor Labs setup skill, workflow skills, and subagents. Google documents Antigravity CLI as the consumer transition path for Gemini CLI, so use this package if your Gemini CLI account is affected by that transition.
1

Install the plugin

Clone the public distribution repository, then validate and install the generated Antigravity plugin from it.
Some Antigravity installs expose the command as antigravity instead of agy. Use the same plugin validate, plugin install, and plugin list subcommands. Restart Antigravity CLI after installing or reinstalling the plugin if the new skills or subagents are not visible.

Set up this machine

Ask your AI coding assistant to run the setup skill.
The setup skill guides package-manager-first endorctl installation, verifies Endor Labs authentication and namespace readiness, and reports missing gh or toolchain prerequisites. It does not run scans, run endorctl host-check, edit shell profiles, auto-install gh, or install language runtimes and package managers.

Run your first workflow

Each workflow is available as a skill and as a subagent. Invoke a subagent with @<name>. Try these example prompts.
See the Agent Kit overview for the full agent catalog, and the safety model for how mutating agents handle approval gates.
