Score: 6.8/10 (Innovation: 6, Technical: 7, Documentation: 7, Utility: 7)

SpadeBox provides a sandboxed set of file, network, and JavaScript execution tools designed for AI agents, with bindings for Rust, JavaScript, and Python. Its combination of capability-based sandboxing via cap-std, a custom JS runtime based on Boa, and built-in secret management for HTTP requests makes it a practical and interesting solution for safely extending agent tool use.
