Antigravity CLI (agy) is now a supported AI engine in terminal-system 1.3.0 and terminal-router 1.2.0, next to Claude Code and Codex. Both releases are on GitHub and in the SysLinuxOS Tools APT repository.
terminal-system 1.3.0: agy as a third engine
In terminal-system you can start the session with Antigravity directly, or switch engine from the right panel at any time with :engine agy. If the active engine fails, the program now tries every other available engine. Before, the fallback could stop too early.
Antigravity suggestions follow the same rules as the other engines: the AI proposes, you confirm, and commands are typed into the left panel only after your choice. For safety agy runs with strict permissions and every tool denied (file read and write, network, commands, MCP), so it can only write the reply text and cannot run anything itself. Set the model with TS_AGY_MODEL; if empty, the CLI default applies.
terminal-system agy :engine agy # from the right panel, in a running session export TS_AGY_MODEL=nome-modello
terminal-router 1.2.0: agy as an observer
In terminal-router the observer in the right panel reads the Cisco or Huawei router output and suggests analysis and commands. Version 1.2.0 adds Antigravity CLI as a third option: choose it with terminal-router agy, or let automatic selection pick it. The order is now Claude Code, then Codex, then agy.
Here too the agy tools are denied, as Codex runs read-only. Set the model with TR_AGY_MODEL. terminal-router status and the startup check now also detect agy on PATH, in ~/.local/bin and under nvm.
terminal-router agy export TR_AGY_MODEL=nome-modello
Upgrade
You need the agy CLI installed and already signed in. If the SysLinuxOS Tools repository is configured:
sudo apt update sudo apt install --only-upgrade terminal-system terminal-router
.deb packages and release notes: terminal-system v1.3.0 and terminal-router v1.2.0.
For the terminal-system commands read the complete 1.2.1 guide; for the router workspace, the article on terminal-router 1.1.0.
