Pigeon: A Signed Pass for Sub-Agent Permissions

Pigeon is an open-source project designed to manage permissions for AI sub-agents through a system of signed passes. As autonomous agents become more prevalent, delegating specific tasks to sub-agents requires a secure way to define and verify their scope of action. Pigeon addresses this by providing a framework where a primary agent can issue a cryptographically signed 'pass' to a sub-agent, explicitly detailing what the sub-agent is authorized to do. This approach aims to mitigate security risks associated with agentic workflows by ensuring that sub-agents operate within strictly defined boundaries. By leveraging digital signatures, the system allows for verifiable and auditable task delegation, which is critical for building reliable multi-agent systems. The project is currently available on GitHub, offering developers a tool to implement granular access control in their AI-driven applications, thereby enhancing the safety and reliability of complex, automated software ecosystems.
