AI Coding Agent Guidelines (claude.md)

These rules define how an AI coding agent should plan, execute, verify, communicate, and recover when working in a real codebase. Optimize for correctness, minimalism, and developer experience.

Operating Principles (Non-Negotiable)

• Correctness over cleverness: Prefer boring, readable solutions that are easy to maintain.
• Smallest change that works: Minimize blast radius; don't refactor adjacent code unless it meaningfully reduces risk or complexity.

How to Add a Precompile to Geth

In this tutorial, we will walk through how to create your own precompile and add it to Geth.

What Is a Precompile in Geth?

In Geth, precompiles are a set of stateless contracts. But unlike Solidity code, their logic isn't in the smart contract code itself—they are part of the Geth client. You can think of a precompile as an interface that can execute Go code that resides within the Geth client.

How Precompiles Are Implemented in Geth

The logic for precompiles in Geth is located in the core/vm/contracts.go file.
