## Summary

A longtime Claude Code user says they are retiring Claude Code as their main coding harness and moving their development setup to Pi, citing frustrations with multi-tab IDE support, features and stability, and system prompt changes. The author says Anthropic announced AGENTS.md support for Claude Code a day after the decision, which was too late to keep them. The author says Claude Code's default Bash tool description is almost 3,000 tokens.
