- [Zoku](https://github.com/kasparovabi/zoku) by [kasparovabi](https://github.com/kasparovabi) — Invisible automation layer that records tool actions across sessions, detects repeated workflow patterns, and injects them into Claude's context via hooks.

Why it fits

• pip install zoku — zero dependencies, ready to use
• Uses the official Claude Code hooks API: PostToolUse, Stop, SessionStart, UserPromptSubmit
• Passively records tool actions across sessions and detects repeated workflow patterns
• Injects discovered patterns back into Claude's context automatically
• 67 tests, MIT licensed
• Zero configuration — install and forget
