Status line customization

Define custom scripting configurations and format dynamic JSON state payloads to customize your TUI status line.

Overview

The status line is positioned at the bottom of the TUI prompt panel. It provides at-a-glance context regarding active agent cycles, workspace environments, context token window usages, and background execution tasks.

Custom status line scripting

For advanced terminal layouts or custom status bar displays, you can route active agent metadata into a custom script.

Configuration

Add a statusLine configuration block to your ~/.gemini/antigravity-cli/settings.json file:

{
    "statusLine": {
        "type": "command",
        "command": "~/.gemini/antigravity-cli/statusline.sh"
    }
}

Whenever the agent state changes, the TUI executes your command script, pipes a detailed state JSON payload directly to the script’s stdin, reads your formatted string from stdout, and renders the result in the prompt’s status line. Full ANSI color codes are supported.

The block accepts three more optional keys: padding adds blank lines above the status line, enabled set to false suspends the script while keeping the command on file, and stack_with_default set to true renders your script below the built-in line instead of replacing it.

Available JSON fields

The JSON payload piped to your script contains the following top-level fields:

Field	Type	Description
`cwd`	string	Current working directory when the CLI was launched.
`session_id`	string	Backward-compatibility alias for `conversation_id`.
`conversation_id`	string	Current unique conversation ID.
`transcript_path`	string	Absolute path to the active conversation transcript log file (optional).
`model`	object	Contains `id` and `display_name` of the active model.
`workspace`	object	Contains `current_dir` and `project_dir` paths.
`version`	string	CLI version string.
`context_window`	object	Contains token usage details: `total_input_tokens`, `total_output_tokens`, `context_window_size`, `used_percentage`, `remaining_percentage`, and `current_usage` sub-object.
`exceeds_200k_tokens`	bool	True if the conversation context has exceeded 200k tokens (null before first API call).
`product`	string	Application name (e.g., `antigravity`).
`quota`	object	Maps model/bucket IDs to their quota status, containing `remaining_fraction`, `reset_time`, and `reset_in_seconds` (optional).
`agent_state`	string	Current state: `idle`, `thinking`, `working`, `tool_use`, `initializing`.
`vcs`	object	Version control info: `type` (git/jj/hg), `branch`, `client`, `dirty` (optional).
`sandbox`	object	Sandbox configuration: `enabled`, `allow_network` (optional).
`artifact_count`	int	Number of artifacts produced in the conversation.
`plan_tier`	string	Subscription tier of the authenticated user (optional).
`email`	string	Email/LDAP of the authenticated user.
`pending_input_count`	int	Number of queued user messages.
`tool_confirmation_pending`	bool	True when a tool confirmation dialog is showing.
`task_count`	int	Number of running background tasks.
`terminal_width`	int	Live width of the interactive terminal.
`execution_mode`	string	Current active prompt execution mode (e.g., `planning`, `fast`).
`vim`	object	Vim editing state: `mode` is `NORMAL`, `INSERT`, `VISUAL`, or `VISUAL LINE`. Present only when Vim editor mode is enabled.

JSON payload example

Here is a fully sanitized, typical JSON payload piped to your status line script:

Example script

You can download a complete, layout-adaptive script from the official statusline.sh example on GitHub. This script renders state badges, handles active branches, and formats context window progress bars dynamically.

Save the script to ~/.gemini/antigravity-cli/statusline.sh and make it executable:

chmod +x ~/.gemini/antigravity-cli/statusline.sh
