What is agy-statusline?

agy-statusline is a small shell script project that adds a custom status line to the Antigravity CLI, a command-line tool known by its short name agy. Instead of a plain prompt, it shows a compact line of information at the bottom of the terminal while you work, covering which AI model is currently active, how much of that session's context window has been used, your working directory and git branch, your account plan, and how much of your usage quota remains. The status line displays two kinds of quota, a five-hour rolling limit and a weekly limit, each shown as a small set of filled and empty circles alongside a percentage and a reset time. It automatically figures out whether to show Claude or Gemini quota based on whichever model is active, so there is nothing to configure by hand for that part. Using it requires three things already installed: jq for parsing JSON, git for reading branch information, and the Antigravity CLI itself already set up. Installation is done by cloning the repository and running an install script, which copies the status line script into the Antigravity CLI's configuration folder and registers it in that tool's settings file. A separate uninstall script removes the entry and restores whatever status line, if any, was configured before. Under the hood, the Antigravity CLI runs whatever command is set as the statusLine in its settings, feeding it the current session state as JSON through standard input, and the script reads that JSON and prints back colored text for the terminal to display. The status line can also be turned on or off at any time from inside the CLI using a slash command.
