What this skill actually does
Core Features
Notes are organized into notebooks and folders with support for tagging, pinning, and wiki-style [[linking]] between entries. Every change is automatically tracked via Git, providing full revision history and multi-device syncing through any Git remote. Search works across all notebooks with full-text and regex support. Notes can be encrypted with password protection using industry-standard encryption.
Bookmarking and Archiving
nb doubles as a powerful bookmarking system. Web pages are downloaded, cleaned, and saved as structured Markdown documents with local full-text search over cached content. Broken links are automatically checked against the Internet Archive Wayback Machine. A built-in local web server provides distraction-free browsing of bookmarks in terminal or GUI browsers.
Integration and Export
Pandoc integration enables importing and exporting notes to dozens of document formats including PDF, DOCX, HTML, and EPUB. The todo and task system tracks actionable items across notebooks. Extensibility is provided through a plugin architecture that lets users add custom functionality.
Agent Skill Applications
nb is particularly well-suited as a persistent knowledge store for AI agents. Its CLI interface, Git versioning, structured plain-text storage, and full-text search make it an ideal backend for agent memory systems. Agents can create, search, link, and tag notes programmatically, while the Git sync ensures multi-agent or multi-machine consistency. The bookmarking feature lets agents archive and index web research for later retrieval.
