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 | $0.02316 | $0.02316 |
| Opus 5.5 | $0.00926 | $0.00926 |
| Sonnet 5.5 | $0.00463 | $0.00463 |
| Haiku 4.5 | $0.00232 | $0.00232 |
Grade A, and why
Tetrad CLAUDE.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 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.
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.
How it starts
The opening of the file, as written. The whole thing — 268 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
Tetrad is a high-performance MCP (Model Context Protocol) server written in Rust that orchestrates three CLI code evaluation tools (Codex, Gemini CLI, Qwen) to validate code produced by Claude Code. It implements a quadruple consensus protocol where no code is accepted without unanimous approval from four intelligences: the three external evaluators + Claude Code itself.
Current Status: Phases 1-5 complete. The project has a functional MCP server, consensus engine, ReasoningBank with SQLite, LRU cache, and hook system. Phase 6 (Release) is in progress - published to crates.io and npm.

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.

Tetrad CLAUDE.md is an instructions file published in the GitHub repository SamoraDC/Tetrad (1 stars, last pushed 9mo ago), licensed MIT. It adds 2,316 tokens to every session, about $0.0093 per session on Opus 5.5. 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.
