Install Pixel
Pixel is a command-line tool: Gemini CLI runs the pixel binary, so install it first (macOS and Linux).
brew install LivioGama/tap/pixelThe install script is the other channel. Neither one changes any agent’s configuration.
What pixel install writes
Nothing for Gemini CLI. pixel doctor judges only what pixel install writes, so it does not see Gemini CLI’s plugin.
Antigravity also keeps its configuration under ~/.gemini/, in ~/.gemini/config/, but it is another agent, and pixel install wires it.
Install the plugin
gemini extensions install https://github.com/LivioGama/pixel.
The plugin never installs the pixel binary. The protocol it loads starts by checking for it (command -v pixel) and tells the agent to work without Pixel’s commands when it is missing.
Check it
pixel doctor .It checks the binary, the daemon and this repository’s index, the parts Gemini CLI relies on once the plugin is in place.
Remove it
Remove the plugin with Gemini CLI’s own plugin or extension command.
