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.

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 | $0.00013 | $0.00299 |
| Opus 5 | $0.00006 | $0.00150 |
| Sonnet 5 | $0.00003 | $0.00060 |
| Haiku 4.5 | $0.00001 | $0.00030 |
Grade A, and why
review scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
Start a read-only review session. The Antigravity daemon runs the worker with an SDK
policy that denies every state-mutating tool (create_file, edit_file,
run_command, generate_image, start_subagent) while allowing read-only
tools, then returns a digest of findings. Writes are blocked by policy, not
merely discouraged by prompt.
!python "${CLAUDE_PLUGIN_ROOT}/scripts/cao-companion.py" --plugin-data "${CLAUDE_PLUGIN_DATA}" session.review "$ARGUMENTS"
The command above prints a JSON object with a session_id. Review sessions cannot
write (mutating tools are stripped), so there are no approval prompts — just watch
until it finishes, using the Antigravity companion via the Bash tool:
- Watch: run
python "${CLAUDE_PLUGIN_ROOT}/scripts/cao-companion.py" --plugin-data "${CLAUDE_PLUGIN_DATA}" session.wait <session_id>. It blocks up to ~25s and returns "running" or "finished". - If it reports "running", run
session.wait <session_id>again. - When it reports the session finished, run
... cao-companion.py session.events <session_id>and show the user the findings digest.
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.

review is a command published in the GitHub repository jinseo-jang/antigravity-plugin-cc (6 stars, last pushed 26d ago), licensed Apache-2.0. It adds 13 tokens to every session and 299 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
