Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00012 | $0.00326 |
| Opus 5 | $0.00006 | $0.00163 |
| Sonnet 5 | $0.00002 | $0.00065 |
| Haiku 4.5 | $0.00001 | $0.00033 |
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 2d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -fsSL https://antigravity.google/cli/install.sh | bash What it actually says
Run:
node "${CLAUDE_PLUGIN_ROOT}/scripts/antigravity-companion.mjs" setup --json
If the JSON result has installed: false:
- Do NOT auto-run any installer. Tell the user the Antigravity CLI (
agy) is not installed and print one of these commands for them to run themselves:
curl -fsSL https://antigravity.google/cli/install.sh | bash
or
brew install --cask antigravity-cli
- After they confirm they have installed it, rerun:
node "${CLAUDE_PLUGIN_ROOT}/scripts/antigravity-companion.mjs" setup
If the JSON result has installed: true and authenticated: false:
- Tell the user to run
!agyand complete sign-in (Google account orANTIGRAVITY_API_KEY).
If the JSON result has ready: true:
- Show a brief confirmation and mention
/ask-antigravity:reviewand/ask-antigravity:rescueas the next things to try.
Output rules:
- Present the final setup output to the user (the human-readable rerun, not the JSON).
- Do not paraphrase the install/auth instructions; surface them verbatim.
- Never run a remote installer on the user's behalf. Only print the install command.
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 contrapuntal/antigravity-cli-plugin-cc (2 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 12 tokens to every session and 326 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
