LBE – open-source execution control layer for AI agents (github.com)

LBE, an open-source execution control layer for AI agents, introduces a vital enhancement to safety protocols by placing a local policy gate between proposed actions by AI agents and their actual execution. This system reviews and validates every action—from file writes to shell commands—locally, eliminating dependencies on cloud services. Currently implemented in Letterblack for Adobe After Effects, LBE ensures that all AI-generated scripts undergo risk checks before they can modify live project files. This development is particularly significant for the AI/ML community as it provides a robust mechanism for real-time action validation without compromising system integrity. LBE operates through a well-defined 7-gate pipeline that secures against threat vectors like malformed requests and unauthorized actions. Notably, it prevents any execution of unapproved actions, reinforcing accountability through an immutable audit log. By offering both a full-control execution layer and a lightweight decision-making SDK, LBE empowers developers with the tools to enhance the safety and reliability of AI systems—crucial for industries where precision and safety are paramount.
