Agentlas-OS is an open-source agent runtime fabric and orchestrator developed by Agentlas AI. It is designed to standardize, coordinate, and govern interactions across heterogeneous AI coding runtimes, agents, and tooling environments via declarative contract specifications and unified communication protocols. The system operates via command-line utilities (such as the agentlas-one CLI and Hephaestus command dispatchers) and leverages a standard-library ACP (Agent Client Protocol) v1 implementation. It manages runtime registries, streams prompts, handles secretless authentication, and coordinates sessions across local runtimes and cloud backends while decoupling model identity from transport mechanisms. Agentlas-OS differentiates itself by focusing on declarative runtime governance, contract validation, and protocol standardization. It includes runtime capability grading (grades A–E, install levels L0–L3), automated runtime drift detection, and native verification for both Agent Plugins 1.0 and Model Context Protocol (MCP) configuration contracts. The project is available as open-source software on GitHub and serves as modular harness infrastructure for developers building reproducible multi-agent developer workflows.
