Show HN: SpadeBox – Sandboxed tools and JavaScript runtime for AI agents

SpadeBox addresses the critical challenge of safely executing code generated by local LLMs by providing an isolated JavaScript runtime environment. This is essential infrastructure for agentic systems where models generate and execute code to accomplish tasks, as it prevents malicious or buggy code from affecting the host system.

For self-hosted LLM deployments, SpadeBox enables developers to give agents the ability to interact with tools and execute logic without requiring full system access. The sandboxed approach is particularly valuable for privacy-conscious organizations running models on-premises, as it maintains strong isolation boundaries between the LLM's generated code and sensitive host resources.

This tool represents the kind of security-first infrastructure needed to make local agent deployment production-ready and trustworthy in enterprise environments.
