Original Text
I run three to seven Claude Code sessions in parallel terminals, and I kept losing track of which was doing what, especially toward the end of the day when your mind is so tired with the constant context-switching.
which-claude-code is a small plugin that adds a title and color to each Claude Code, so you know right away which Claude Code session does what.
1. On every prompt submit, a UserPromptSubmit hook forks a background claude -p --model haiku call that reads the last few transcript turns and writes a 3-6 word title to ~/.claude/which-claude-code/titles/<session_id>.txt. The hook returns in ~10ms so the prompt isn't delayed.
2. A statusline script prints ● <title> · <model> · <cwd> (<branch>) on every render. The dot and title are tinted from a 20-color palette hashed off the session ID.
Enjoy!
