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.

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 | $0.01434 | $0.01434 |
| Opus 5 | $0.00717 | $0.00717 |
| Sonnet 5 | $0.00287 | $0.00287 |
| Haiku 4.5 | $0.00143 | $0.00143 |
Grade C, and why
evm-cortex AGENTS.md 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 2d 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.

EVM Cortex
Ethereum Protocol Engineering Squad
This file is for Codex CLI (OpenAI). If you're using Claude Code, see CLAUDE.md or just run ./install.sh.
What is this?
EVM Cortex turns your AI coding assistant into a specialized Ethereum protocol engineering team. Agents cover Solidity development, security auditing, DeFi integration, testing, and deployment -- everything needed to build, audit, and ship smart contracts.
Setup (Codex CLI)
./install-codex.sh
Prerequisites
- Foundry:
curl -L https://foundry.paradigm.xyz | bash && foundryup - Slither:
pip install slither-analyzer - Aderyn (optional):
cargo install aderyn

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.

evm-cortex AGENTS.md is an instructions file published in the GitHub repository ccashwell/evm-cortex (127 stars, last pushed 22d ago), licensed MIT. It adds 1,434 tokens to every session, about $0.0072 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.
