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 | $0.00212 | $0.00212 |
| Opus 5.5 | $0.00085 | $0.00085 |
| Sonnet 5.5 | $0.00042 | $0.00042 |
| Haiku 4.5 | $0.00021 | $0.00021 |
Grade A, and why
idd-skill GEMINI.md 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 1mo 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.
This is a copy
88% identical to idd-skill CLAUDE.md — 30 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
Guidelines for AI Agents (Antigravity CLI)
This file is the Antigravity CLI (formerly Gemini CLI) entry point.
Antigravity CLI reads GEMINI.md by default rather than AGENTS.md, so
the full guidelines defined there are imported below; treat the
imported content as if it were written directly in this file.
@AGENTS.md
Antigravity-specific notes
schemas/token-cost-event.schema.json'svendorenum has no value for Antigravity yet (grok,claude,codexonly), so skip callingnode scripts/token-cost-event.mjs(Dogfood: token-cost events) for now rather than passing a mismatched vendor — a wrong tag would corrupt the shared dataset.- See docs/idd-workflow.md for the cross-agent entry path and phase routing this loop follows.
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.
