Hey Product Hunt! 👋 I’m the maker of agent-contracts. If you’re building LangGraph agents, you’ve probably felt the pain of manually wiring graphs, keeping node I/O consistent, and debugging why routing chose a certain path. agent-contracts lets you: - Define nodes declaratively with contracts (I/O, state, triggers) - Auto-build the graph from those contracts - Use hybrid routing (rules + LLM) for predictable + flexible orchestration I’d love feedback on: 1. What’s the biggest pain in your current LangGraph setup? 2. Would you prefer a “minimal core” or more batteries-included tooling (CLI, visualization, templates)? 3. What integrations would make this immediately useful (LangSmith, OpenTelemetry, etc.)? Happy to answer anything—thanks for checking it out! 🙏
