Building a Custom Coding Harness with Pi

Summary

A developer shares his move from Claude Code to Pi and explains how a small coding-agent core can support a highly customizable harness. AGENTS.md defines stable rules, Skills add capabilities on demand, and Packages provide orchestration, research, context, and side-thread controls. His workflow separates clarification, read-only scouting, implementation, and fresh review, with only one writer allowed per directory. He also warns that Pi has maximum privileges and no sandbox by default.
