TL;DR I spent 6 months building a self-improving coding agent on top of Claude Code — an orchestrator that hands work to sub-agents, persists its own state, and rewrites its own prompts when it gets things wrong. Here are 5 lessons I wish someone had told me on day one, with the war stories that taught me each one. The Problem I kept hitting the same wall with single-shot LLM coding sessions. The model would do great work for 30 minutes, then forget a decis
