MAS-Lab¶
A specification-driven foundation for multi-agent systems that are testable, reproducible, observable, and governable.
Multi-agent demos are easy to build; production-grade systems are not. MAS-Lab helps teams close that gap with declarative specs, runtime enforcement, and repeatable experiments — without gluing everything together in prompts and scripts.
What it is¶
MAS-Lab is an open toolkit for engineering multi-agent systems. You describe agents, teams, tools, workflows, and policies in YAML; the runtime executes and checks behavior at important boundaries; experiments and traces let you compare designs and audit what happened.
The same specification travels from local development through benchmarks to governed deployment — intent stays explicit instead of scattered across code and prompts.
Why it exists¶
As systems grow, behavior becomes hard to reproduce, debug, and govern. Small changes to prompts, tools, or coordination can silently shift outcomes. MAS-Lab separates what the system should do from what it actually did at runtime, and connects them with specs, contracts, overlays, and observability.
Who it is for¶
Developers — build modular agent apps from specs instead of one-off glue. Declare agents, tools, and workflows once, then iterate safely across models and coordination patterns.
Enterprises — roll out agentic workflows with governance, traceability, and operational control. Policies and budgets attach as overlays without rewriting core logic.
Researchers — run controlled, multi-run campaigns; vary designs and infrastructure; replay trajectories with reproducibility built in.
