Monitor Gemini API CLI with FrontierStack

The Gemini API CLI, gemini-api, is Google's experimental command-line tool for the Gemini API. It isn't an agent itself. Claude Code, Codex and other agents run it from the shell to use Gemini models, generate images, audio and video, analyse files, or start Gemini managed agents. FrontierStack detects it and its version on this Mac or over SSH, installs or updates it with Google's script, and opens gemini-api configure to save a key. It can keep its own copy of the key, so after you rotate a Gemini key in KeyRotate, save the new key there too.
