Architect-level development, audit, and migration of multi-agent systems using LangGraph (v1+) and LangChain (v1+). Use when building or refactoring supervisor/subagent architectures, orchestrator-worker workflows, routing/hand-offs, agentic RAG, memory (short + long-term), state + context engineering, guardrails + human-in-the-loop, MCP tool integration, observability (LangSmith/OpenTelemetry), deployment, and performance/cost optimization — or when migrating off deprecated patterns like…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# LangGraph Multi-Agent ## What this skill does Build, review, and modernize production-grade multi-agent systems with LangGraph/LangChain while staying version-accurate by default: always resolve the *current* APIs from docs + installed versions, and fall back to `opensrc/` source snapshots for under-the-hood edge cases. ## Default operating rules (do these every time) 1. Treat all LangGraph/LangChain APIs as **versioned**; never “code from memory” for any API surface that might have changed. 2. Establish **ground truth** before coding: - Determine installed/pinned versions (repo lockfiles + `importlib.metadata`). - Query official docs via `langchain-docs.SearchDocsByLangChain`. - Use Context7 for canonical API references and examples. 3. When docs are ambiguous or behavior is subtle, inspect dependency internals via `opensrc/` (read-only): - Run `npx opensrc pypi:<package>@<version> --modify=false` - Check `opensrc/sources.json` and cite exact `opensrc/...` paths + versions in your writeup. Use `references/research_playbook.md` when you need a rigorous doc-sweep, including `llms.txt`-driven crawling of LangGraph docs. ## Workflow decision tree …

How to install
mdr add bjornmelin/dev-skills/langgraph-multiagent@sha256:524d8992eea7d3d2The line at the top of this page pins the label git:20260126.735ce96, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
