Antigravity Exec

Use this skill to delegate tasks to the Antigravity CLI (agy) as a sub-agent. Triggers on: 'ask antigravity', 'run it with antigravity', 'agy -p', or when the user explicitly wants to use the Antigravity CLI for a task.

Antigravity CLI Sub-Agent

A skill for invoking the Antigravity CLI (agy) as a sub-agent in non-interactive mode (-p / --print).

Prerequisites

agy is installed and on PATH (check with agy --version).

How to run

Run non-interactively with agy -p via the Bash tool. The prompt is passed as the flag's argument.

Basic command

agy -p "<task>"

The response is printed to stdout. Example:

agy -p "Reply with exactly one sentence: what is the capital of Japan?"
# -> The capital of Japan is Tokyo.

Flags

Flag	Purpose
`-p` / `--print` / `--prompt`	Run a single prompt non-interactively and print the response
`--print-timeout <dur>`	Timeout for print mode (default `5m0s`; raise for long tasks, e.g. `10m`)
`--dangerously-skip-permissions`	Auto-approve all tool permission requests without prompting
`--add-dir <path>`	Add a directory to the workspace (repeatable)
`--sandbox`	Run in a sandbox with terminal restrictions enabled
`-c` / `--continue`	Continue the most recent conversation
`--conversation <id>`	Resume a previous conversation by ID
`--log-file <path>`	Override the CLI log file path

Long prompts

-p requires its value as an argument (it does not read the prompt from stdin). For a long prompt, pass it via command substitution:

agy -p "$(cat prompt.md)"

Notes

The prompt must be supplied as the -p argument — piping into a bare agy -p fails with "flag needs an argument: -p".
The default print timeout is 5 minutes. For longer tasks raise it with --print-timeout and set a generous Bash timeout (up to 10 minutes: timeout: 600000).
Tool actions may prompt for permission. For unattended automation that needs to write/run, add --dangerously-skip-permissions (and prefer --sandbox to limit the blast radius).
The current conversation context is not carried over. Include any required information in the prompt, or use -c / --conversation to resume a prior session.
Summarize the result back to the user.
