 ## Antigravity CLI
 
-Google is renaming Gemini CLI to Antigravity CLI (the `agy` binary); the same extension installs there:
-
 ```bash
 agy plugin install https://github.com/DietrichGebert/ponytail
 ```
 
-It reuses this repo's `gemini-extension.json`. One difference: Antigravity converts the `/ponytail` commands into skills, so you type them into the chat (e.g. `/ponytail-review` as a message) instead of picking them from a slash menu. Until the migration completes (around June 18, 2026), `gemini extensions install` still works too. To run it as an always-on rule instead, drop the ruleset into `.agents/rules/`.
+Installs the six skills, and Antigravity turns the `/ponytail` commands into skills as well, so you [call them as slash commands](https://www.antigravity.google/docs/skills#slash-command-conversion) such as `/ponytail-review`. No lifecycle hooks, so levels don't persist. For the always-on ruleset, copy [`AGENTS.md`](AGENTS.md) into your project; Antigravity [reads it as workspace rules](https://www.antigravity.google/docs/rules). Install verified with Antigravity CLI 1.3.3.
