@surrealdb/langgraph

SurrealDB checkpoint saver, store and node cache for LangGraph.js, plus a SurrealDB Agent Memory store

toolweave

Typed code-mode tool orchestration for LLM agents: tools become TypeScript declarations, generated programs are type-checked (routeable checker backends), repaired via diagnostics, and executed in a QuickJS sandbox.
