claude-antigravity-orchestrator

Claude orchestrates; the Antigravity CLI (agy) does the work — web search, downloads, scanning, validation, and first-draft code/UI — on a separate quota, so Claude spends far fewer tokens. Capability

antigravity-delegate

Make Claude the orchestrator and the Antigravity CLI (agy) the worker. Offload token-heavy, low-judgment grunt work — web search, downloads, scanning big logs/codebases, running validators — to the local agy CLI in headless mode. agy eats the volume; Claude gets back only the small distilled answer and keeps the reasoning.

Built for workflows like benchmarking a context-heavy system against competitors, where the search / download / validate legwork would otherwise burn a pile of Claude Opus tokens while agy sits idle.

agy is Google's official replacement for the Gemini CLI, which sunsets for individual / Google One / AI Pro / Ultra tiers on 2026-06-18. It authenticates via the system keyring and exposes Gemini 3.x, Claude, and open-weight models.

Install

# 1. Antigravity CLI (the worker)
curl -fsSL https://antigravity.google/cli/install.sh | bash

# 2. the skill
bash install.sh

Installs to every Agent-Skills path (Claude Code, Codex/Amp/Goose, opencode, Antigravity, OpenClaw). Manual: copy skills/antigravity-delegate/ into your agent's skills dir.

Requirements

Antigravity CLI (agy) — curl -fsSL https://antigravity.google/cli/install.sh | bash
That's it — agy prints plain text, so no jq needed.

Name clash: the Antigravity IDE ships its own agy launcher. If both are installed, keep the IDE launcher as agy and rename the CLI to agy-cli (mv ~/.local/bin/agy ~/.local/bin/agy-cli). The wrapper prefers agy-cli, then agy, and honors AGY_BIN=/full/path/to/cli.

Usage

/antigravity-delegate "<task>" [--model "Gemini 3.5 Flash (Low)"] [--mode search|read|write] [--out FILE]

Or call the helper directly:

skills/antigravity-delegate/scripts/agy-run.sh "<task>" --mode search --model "Gemini 3.5 Flash (Low)"

Arg	Default	Meaning
task	required	one closed, self-contained instruction with a bounded deliverable
`--mode`	`search`	`search`/`read` = read-only intent; `write` = auto-approve tools
`--model`	`"Gemini 3.5 Flash (Low)"`	run `agy models` for the list; use a Pro/Thinking variant for reasoning
`--dir`	—	scope tool access to a directory (`--add-dir`)
`--out`	—	agy writes full output to FILE; stdout is a one-line summary
`--timeout`	`5m`	print-mode wait timeout

Models on tap (via agy models): Gemini 3.5 Flash, Gemini 3.1 Pro, Claude Sonnet/Opus 4.6, GPT-OSS 120B — pick per subtask.

When to delegate

agy runs on your Google One / Antigravity quota — separate from Claude's tokens — so anything it does well is tokens Claude never spends. Two buckets:

Delegate ✅	Keep in Claude ❌
web search → answer	architecture / trade-off decisions
download files/datasets	security-sensitive code or review
grep huge logs/codebases	shipping code with no review
run benchmark/validator → PASS/FAIL	synthesizing the final result
summarize a giant file	anything tiny (overhead not worth it)
frontend/UI scaffold, boilerplate, codemod (draft)
generate unit tests (draft)

Rule: delegate when the cost is volume or the value is a reviewable draft. Keep it when the value is a final decision. A draft from agy is an input to Claude's judgment, not a substitute — Claude reviews before anything ships.

Which model?

agy models lists what your account can use. Route by subtask (quote the exact name):

Subtask	Model
search / download / scan / validate	`Gemini 3.5 Flash (Low)` — cheapest, fastest
frontend/UI drafts, code-gen, multimodal	`Gemini 3.5 Flash (High)`
deep reasoning / long-context	`Gemini 3.1 Pro (High)`
correctness-sensitive code, test gen	`Claude Sonnet 4.6 (Thinking)`
hardest reasoning / knowledge	`Claude Opus 4.6 (Thinking)`
open-weight fallback	`GPT-OSS 120B (Medium)`

Cheapest-capable wins; escalate only when the worker must reason or the draft must be high quality.

How it works

scripts/agy-run.sh runs agy -p "<task>" --model "<name>" (adding --dangerously-skip-permissions in write mode, --add-dir to scope), and prints agy's plain-text answer to stdout. Exit codes pass through from agy; the wrapper adds 2 for bad input and 1 for an empty response.
