Phrony is an open specification and open-source runtime for declaring, deploying, and running AI agents. It treats AI agents similarly to how teams manage services and infrastructure, making them first-class primitives.

• Declarative Agent Specification: Define your AI agents using versioned YAML manifests. This includes specifying tools, policies, secrets, and limits.

• Reference Runtime: A runtime that executes these agent manifests. It handles the model loop, tool dispatch, policies, limits, human-in-the-loop interactions, and tracing.

• SDK for Applications and Tool Workers: Develop applications and tool workers that interact with the Phrony runtime.

• Deployment Workflow: Declare agents in Git, deploy named versions to the runtime, and run them through the Phrony CLI or gRPC.

• Key Components: Includes the official open-source Phrony Agent runtime (daemon, operator CLI, gRPC API) and a TypeScript client SDK for agents and interactive sessions.

• License: Open-source components are released under the MIT license.

Phrony aims to streamline the production deployment and management of AI agents by providing a structured and standardized approach.
