Nu

Nu functions as a self-hosted personal agent, offering robust control and transparency for managing various tasks. Key features include: • Policy-driven tool call validation • Approval required for unallowed actions • Persistent state logging for crash recovery • Sandboxed execution for shell commands • Extensible through custom packages Built on the Rebuno framework, Nu ensures that every tool call adheres to your predefined policies. Any action not explicitly permitted will await your direct approval, giving you complete oversight. This focus on user control means you can define rules in plain YAML, making them easy to read, edit, and version control, ensuring the agent operates precisely within your boundaries. One of Nu's core strengths is its resilience; every operational step is logged before execution. This means if the system crashes or restarts, Nu can seamlessly resume from where it left off without duplicating effort, ensuring efficiency and continuity. Furthermore, shell commands are executed within a secure sandbox, preventing the agent from accessing your sensitive information unless explicitly provided for a specific task. Packages allow deep customization, enabling you to add new tools, skills, or even replace core components like the sandbox or chat integrations. This tool is ideal for developers, power users, and security-conscious individuals who require a personal assistant with maximum transparency and configurability. It's perfect for managing tasks, automating routines, and extending functionality across different chat applications, all while maintaining strict control over data and operations. The open-source, MIT-licensed nature provides flexibility and community support.
