agent-contracts – Contract-driven architecture for scalable LangGraph agents

Summary: agent-contracts enables building LangGraph agents by defining declarative node contracts that specify I/O, state, and triggers. It auto-wires graphs and uses hybrid rule and LLM routing for flexible orchestration.

What it does

It constructs LangGraph agents from declarative contracts, automatically building the graph and managing routing through combined rule-based and LLM methods.

Who it's for

Developers building LangGraph agents who need consistent node I/O and streamlined graph wiring.

Why it matters

It reduces manual graph wiring and debugging by automating graph construction and routing decisions.
