  Delegate a coding task to the Google Antigravity CLI (`agy`) as a background implementer, then review
  its diff and land it yourself. Use this whenever the user wants to hand implementation work to
  Antigravity or agy - phrasings like "have Antigravity do X", "delegate this to agy", "run it through
  agy", or "use Antigravity to implement/fix/refactor" - or wants to run a queue of coding tasks
  through agy while staying the reviewer. DO NOT USE for tasks small enough to do inline, or when the
  user wants the code written directly without delegating.
license: MIT
compatibility: Requires the `agy` CLI installed and authenticated, Node 18+, and git. The orchestrating agent must be able to run shell commands and read files. Shell examples assume bash/zsh (macOS/Linux, or Git Bash/WSL on Windows). Windows launch is not yet verified for this relay.

# Antigravity Delegate

You are the **orchestrator**. This skill lets you hand a bounded coding task to a separate
**implementer** - the Google Antigravity CLI (`agy`) - then review what it produced and land it
yourself. You write the brief and own the judgment; Antigravity does the typing in its own
conversation; you verify and commit.

Nothing here is specific to one orchestrating agent. The loop needs only the ability to run a shell
command and read a file, so any comparable agent can drive it. It is designed for and run on Claude
Code; treat other orchestrators as designed-for, not yet proven.

## When NOT to use this

- The task is small enough to just do inline - delegation overhead is not worth it.
- The `agy` CLI is not installed or not authenticated. Install it from Antigravity's CLI docs and run
  the first-launch setup.
- You want to write the code yourself, or you only need a review without edits. This relay does not
  expose a proven CLI-enforced read-only mode yet.

## Prerequisites (check once)

1. `agy help` succeeds. If not, install the Antigravity CLI and complete first-launch setup.
2. `agy models` succeeds. That proves the CLI can authenticate and list the available model labels.
3. You are in (or will point `--cd` at) the target git repository.

These checks do not prove that a headless write will be approved. In `--print` mode, Antigravity
cannot prompt for a write permission and may auto-deny it. The relay detects that denial instead of
reporting completion.

## Choose the implementer model

`agy` has a configured default model, so `--model` is optional. Use it when the human has a preferred
Antigravity model label for the task. Otherwise let Antigravity use its own current default rather than
guessing.

## The loop

Run these five steps per task. Steps 1, 4, and 5 are your judgment; 2 and 3 are mechanical.

### 1. Write the brief

Antigravity sees only the text you send plus what it can inspect in the workspace - no chat history, no
shared context. Everything the task needs goes in the brief: the goal, the current state, what to
change, what to leave untouched, the project's **actual** gate commands, and a report contract. Tell
Antigravity it will **not** commit (you will). Keep one task per brief. Full guidance and a template:
[references/writing-the-brief.md](references/writing-the-brief.md).

### 2. Dispatch

Send the brief to Antigravity with the bundled helper. It wraps `agy --print`, captures the run, and
writes a structured `result.json` - so your only job is "run a command, read a file." (`<skill-dir>`
below is this skill's installed directory - the folder containing this `SKILL.md`.)

```bash
node "<skill-dir>/scripts/relay.mjs" --brief brief.txt --cd /path/to/repo
# choose a model label:                 add --model "<label from agy models>"
# enable Antigravity terminal sandbox:  add --sandbox
# resume the most recent conversation:  add --resume-last  (delta brief only)
# see all options:                      node .../relay.mjs --help
```

The helper starts a fresh Antigravity pr
