Antigravity Agy
Run Hermes on a Google Antigravity subscription through the official agy CLI, with agy as the model only: a generated custom agent removes agy's built-in tools, Hermes tools are exposed through an inventory-only MCP server with native function calling, and every tool call is handed back to Hermes. Fails closed on any non-Hermes tool step or silent agent fallback; pre-warms agy for fast tool loops.
Good to know before installing
Routes inference through Google's official agy CLI and counts against the Antigravity/Gemini subscription agy is signed in to; the plugin never reads, copies or links agy's credential files. agy runs in your real HOME with the gateway's environment; by default the plugin moves the agy conversation records created by its own idle pre-warmed processes under ~/.gemini/antigravity-cli/ to the trash (trash-put from PATH; ANTIGRAVITY_AGY_CLEANUP=off disables) and pre-warms up to 4 idle agy processes (~400 MB each).

How to install
- Install it. Hermes asks for any API keys it needs, then asks whether to turn it on.
hermes plugins install antigravity-agy - Said no? Turn it on later:
hermes plugins enable antigravity-agy - Restart Hermes so it loads the plugin.
Some plugins also need a sign-in or settings: see Full setup & settings. Memory plugins ask whether to become your memory provider instead. Steps follow the official plugins guide (opens in a new tab).
