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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00018 | $0.00358 |
| Opus 5 | $0.00009 | $0.00179 |
| Sonnet 5 | $0.00004 | $0.00072 |
| Haiku 4.5 | $0.00002 | $0.00036 |
Grade C, and why
agy-preflight 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 4d 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.

curl | sh runs whatever the server returns today, which is not necessarily what it returned when this was reviewed.

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
Antigravity (agy) Preflight
Check the supported Google terminal backend: Antigravity CLI (agy). This is
separate from /cc-suite:codex-preflight (Codex) and /cc-suite:grok-preflight
(Grok Build).
Step 1: Run the preflight script
bash "${CLAUDE_PLUGIN_ROOT}/scripts/agy-preflight.sh"
Parse the JSON output from stdout. The probe is deadline-bounded and does not fall back to the deprecated consumer Gemini CLI.
Step 2: Display results
## Antigravity CLI Preflight Results
**Backend**: {backend}
**Status**: {status}
**agy version**: {agy_version}
**Default model**: {default_model}
**Workspace MCP bridge**: {workspace_mcp_registered}
**Claude reverse bridge**: {claude_mcp_registered}
### Available Models
{models, one per row}
Step 3: Handle errors
agy_not_found→ install with:curl -fsSL https://antigravity.google/cli/install.sh | bashagy_not_authenticated→ runagyinteractively and complete Google sign-inagy_probe_timeout→ check network/authentication, then retry- Empty
models→ do not continue with an agy delegation; runagyinteractively
Do not silently substitute gemini. Enterprise users who intentionally retain
Gemini CLI should use that tool directly; cc-suite's project bridge targets agy.
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.

agy-preflight is a command published in the GitHub repository xiaolai/cc-suite (44 stars, last pushed 2d ago), licensed ISC. It adds 18 tokens to every session and 358 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 2026-08-30.
