@moldea.ai/adapter-langgraph

Deterministic runtime evidence and diagnostics for LangGraph TypeScript Graph API and Functional API workflows declared by moldea agents.

Installation

pnpm add @moldea.ai/adapter-langgraph @moldea.ai/core @moldea.ai/repository

The package exports one immutable adapter:

import { langGraphAdapter } from '@moldea.ai/adapter-langgraph';
import { createCore } from '@moldea.ai/core';

const core = createCore({ adapters: [langGraphAdapter] });

Verified targets

Version 3.0.3 supports Repository Format 1, @moldea.ai/core ^4.0.0, and declared ranges that intersect @langchain/langgraph >=1.4.12 with companion @langchain/core >=1.2.9. Those minimum versions are verified. Later stable releases are eligible for deterministic inspection on a best-effort basis and must still match the documented source patterns. Qualification evidence records the exact package versions and date used for each execution. The targets recognize:

• directly exported compiled StateGraph definitions using supported inline fluent or single-owner module-local builders
• closed modern Graph API schema initialization and direct input/output schema wiring
• supported node, direct-edge, waiting-edge, and conditional-edge operations
• directly exported Functional API entrypoint(...) definitions
• direct task, interrupt, previous-state, and final-state patterns in an entrypoint's own lexical body

The adapter reads source through the Repository contract. It does not execute LangGraph, import inspected modules, inspect lockfiles or installed packages, contact LangSmith or model providers, or write to the repository.

Public API

The package exports only langGraphAdapter. It has no default export, configuration factory, LangGraph facade, parser export, or public diagnostic registry.
