Wraps the nb CLI to give Claude proper note-taking capabilities without shell escaping headaches. Exposes operations for creating, editing, searching, and organizing Markdown notes, todos, and bookmarks through JSON parameters instead of raw shell commands. Handles notebook context explicitly so you can maintain separate note collections per project. Commands include nb.add for new notes with tags and folders, nb.search for full-text queries, nb.todo for task management, and nb.move for reorganization. Automatically creates notebooks and manages Git commits in the background. Particularly helpful if you're coordinating multiple LLMs on the same codebase and need structured, searchable notes that survive backticks and code blocks. Requires nb installed locally and supports configuration via environment variables or CLI flags.
