I built a Rust learning project for implementing a Claude Code-style agent harness from scratch

The blog post describes a Rust-based learning project to build an AI agent harness, illustrating the progression from a basic agent loop to a full-fledged tool management system. It includes 20 chapters, each serving as an independent Rust crate, aimed at teaching systematic Rust programming practices alongside AI applications. The author invites feedback particularly on the organization, abstractions, and documentation of the project.
