My impressions after using Claude Code for six months

Last time when I started to write this post, I got carried away. My brain was on verge of explosion because Claude and I had worked together on so many projects and stuff over the last six months. My first interaction with the harness was in February 2026 when I started adopting it in my daily work and personal projects slightly more than Codex CLI. I went from having a large CLAUDE.md file in my global configuration to a smaller one that works 99% of the time.
