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 | $0.01768 | $0.01768 |
| Opus 5.5 | $0.00707 | $0.00707 |
| Sonnet 5.5 | $0.00354 | $0.00354 |
| Haiku 4.5 | $0.00177 | $0.00177 |
Grade A, and why
antigravity CLAUDE.md scanned grade A with 1 finding 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 2mo 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.
- **SKILL.md files use relative script paths** (`uv run scripts/x.py`), but a worker's cwd is its own job dir, not the skill dir. `skill_preamble()` therefore injects each skill's **absolute** path. Without it, every scr How it starts

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
What this is
An MCP (Model Context Protocol) server that exposes the Antigravity CLI (agy, Google's Gemini agent) as a set of tools usable from Claude Code, Claude Desktop, Cursor, and Windsurf. The animating idea: Claude is the Conductor/frontier model, and agy/Gemini is a cheaper executing agent to which Claude offloads bulky, token-heavy work (web research, codebase indexing, commit-message generation, cross-model review) to keep Claude's own context lean. See the antigravity_workflow and antigravity_research_recipe MCP prompts (in antigravity_mcp/prompts.py) for the operating philosophy.
The implementation lives in the antigravity_mcp/ package; main.py is a thin entrypoint. Layout: app.py (the shared FastMCP instance), agy.py (subprocess/model-tier helpers + the pure skill layer, no MCP — unit-testable), jobs.py (filesystem-backed background jobs + _start_batch fan-out scaffolding), delegation.py, research.py, architect.py, skills.py, codegit.py, prompts.py, and server.py (side-effect imports that register everything + main()).
Three multi-step pipelines build on this: deep-research (research_fanout → research_status → collect_digests, plus the /deep-research skill and antigravity_research_recipe prompt); architect/build (propose_design_questions → review_fanout/research_fanout → draft_design_doc, plus the /architect skill and antigravity_build_recipe prompt) — a Spec-Driven loop (Requirements → Design → Tasks → Implement) for creating/improving codebases; and science (propose_science_plan → science_fanout → research_status → collect_digests, plus the /science-research skill and antigravity_science_recipe prompt). All three share the same fan-out scaffolding (_start_batch) and batch collectors (research_status/collect_digests are batch-generic — they read any sub_NN/subreport.md + manifest.json, so review and science batches reuse them unchanged).
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.

antigravity CLAUDE.md is an instructions file published in the GitHub repository JamesZor/antigravity (0 stars, last pushed 3mo ago), licensed MIT. It adds 1,768 tokens to every session, about $0.0071 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
