hermes

hermes is a plugin for Claude Code from wildcat-finance/skills. Its token cost is not measured, scanned A, original, Apache-2.0.

A Solidity gas-optimisation process that uses measurements from Foundry, a toolkit for building and testing Ethereum smart contracts. It only accepts changes supported by those measurements.

In plain words
What is it for?
Use it to measure and assess gas-usage changes in Solidity contracts with Foundry and its Forge testing tool.
Why use it?
It helps reduce the computational fee paid to run smart-contract code while checking that the proposed change has measured evidence.

Security

Grade A, and why

hermes 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 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.

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.

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.
