zenflow

Zenflow provides a robust multi-agent orchestration engine built for Go, transforming declarative YAML agent configurations into executable plans. Key capabilities include: * Declarative YAML for agent workflows * Coordinator for event routing and run finalization * Hub-and-spoke messaging architecture * Race-safe mailbox delivery * Spec-first validation for early error detection This engine routes events through hub-and-spoke mailboxes, ensuring race-safe message delivery without silent data loss or out-of-order sequencing. The core design emphasizes auditability, as peer agents do not directly communicate, maintaining a clear topology. Workflows are expressed in a compact, composable YAML specification, supporting steps, dependencies, parallel fan-out, conditional logic (CEL), loops, and sub-workflow reuse. Each plan is reviewable as a YAML file, integrating smoothly into version control systems. Zenflow prioritizes reliability and performance, validating workflows against a comprehensive schema and Go validator with numerous compliance checks before any external calls. This pre-execution validation catches common errors like cycles, missing dependencies, or malformed conditions in milliseconds, preventing costly runtime failures. The system is multi-provider verified, compatible with major cloud model providers, offering flexibility in deployment options. It comes as a single static Go binary, requiring no additional runtime environments. Ideal for developers and engineering teams building complex, distributed systems that require coordinated actions across multiple components. It's suitable for embedding within long-running services or for executing one-shot runs via the command-line interface, offering a versatile tool for managing intricate process flows and ensuring robust operation.
