Rust Implementation of Agent Harness
doodlestein · x · 2026-07-15
The author mentions using native Claude Code and Codex alongside a custom toolchain; if Pi is required, they opt for their own Rust-based implementation.
The quoted content introduces piagentrust: a Rust implementation of the Pi Agent. The author clarifies that it functions more like a minimalist, extensible agent harness, similar in purpose to Claude Code / Codex, and also serves as the core agent framework within the OpenClaw project.
Additional details include:
- This Rust version is not a simple port, but features distinctly different implementation methods
- The author notes that incrementally implementing new features can be even more complex than the rest of the project
- The goal is to retain identical capabilities while offering a more flexible foundation for building upon.
