A command that checks whether the Antigravity command-line tool is installed, available on the system path, and responding.

Use it before other Antigravity commands to check the agy CLI, PDF support, semantic search support, media support, and graph support.

It quickly shows whether the required tool is ready and reports related optional components that may be missing.

setup — Command for Claude Code by MarcosNahuel/antigravity-plugin-cc

Install

Getting it into your agent

This one installs as part of its plugin. Adding the marketplace and installing the plugin brings it with everything else the plugin ships.

Claude Code

/plugin marketplace add MarcosNahuel/antigravity-plugin-cc

Claude Code

/plugin install antigravity

Made for: Claude Code.

Or install antigravity, the plugin that ships this one along with the rest of its 2 skills, 22 commands, 1 agent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00021	$0.00742
Opus 5.5	$0.00008	$0.00297
Sonnet 5.5	$0.00004	$0.00148
Haiku 4.5	$0.00002	$0.00074

Security

Grade C, and why

setup scanned grade C with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 25d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 64 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Phase 0 — Stack check (ONE Bash call, no agy)

First report the whole agent stack — what's installed, what's missing, how to fix each — so the user knows which /agy:* capabilities are ready:

python "${CLAUDE_PLUGIN_ROOT:-$PWD/plugins/antigravity}/scripts/stack_check.py"

It checks: agy CLI (required), PyMuPDF/fitz (required for /agy:notebook PDFs), sqlite-vec (optional — /agy:notebook --semantic), ffmpeg (optional — long media for /agy:transcribe), and graphify (optional — /agy:graph). Present the table and the fix line for anything missing. Prints STACK n/5 present.

It also does a read-only check of agy's own global settings.json (~/.gemini/antigravity-cli/) for toolPermission: "always-proceed". If found, present the warning block as-is: this plugin already runs agy --print with --dangerously-skip-permissions (required — there is no TTY to answer a permission prompt in headless mode), so always-proceed on top of that means agy never asks for confirmation on anything, from either source. Never edit this file or any other agy config yourself — only surface the warning and the manual steps to scope it down; changing Nahuel's global agy configuration is out of scope for this command.

Phase 1 — agy health ping

Route this to the antigravity:agy-rescue subagent in MODE: setup.

Pass this header block to the subagent:

MODE: setup
INTENSITY:
MODEL:
RESUME: false
WRITE_FILE:
USER_TEXT:

The subagent will:

Resolve the agy binary (PATH, then AGY_BIN, then per-OS fallback paths).
Try agy changelog to read the current version.
Run a 30s ping: a minimal --print call expecting "pong" back.
Report binary path, version, and ping status.

Output rules:

Present the final setup output to the user as-is.
If the binary is missing, tell the user to install Antigravity:
- Windows (PowerShell): irm https://antigravity.google/cli/install.ps1 | iex
- macOS / Linux (bash): curl -fsSL https://antigravity.google/cli/install.sh | bash

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

setup is a command published in the GitHub repository MarcosNahuel/antigravity-plugin-cc (30 stars, last pushed 8d ago), licensed MIT. It adds 21 tokens to every session and 742 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it C with 2 findings (downloads and executes remote code, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
