Antigravity CLI Sub-Agent
A skill for invoking the Antigravity CLI (agy) as a sub-agent in non-interactive mode (-p / --print).
Prerequisites
agyis installed and onPATH(check withagy --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
-pargument — piping into a bareagy -pfails with "flag needs an argument: -p". - The default print timeout is 5 minutes. For longer tasks raise it with
--print-timeoutand 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--sandboxto limit the blast radius). - The current conversation context is not carried over. Include any required information in the prompt, or use
-c/--conversationto resume a prior session. - Summarize the result back to the user.
