langgraph SKILL.md skillA
langgraph from jnpiyush/agentx is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add jnpiyush/agentx/langgraph@v1.0.0Pins v1.0.0 in mdr.lock. Pin the fingerprint instead.

Build stateful, durable agent workflows with LangGraph. Use when implementing graph-based orchestration, long-running agent state, human-in-the-loop checkpoints, subgraphs, memory, or LangSmith-observed agent execution.
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 > WHEN: Building stateful agent orchestration with explicit graph nodes, durable execution, checkpointing, interrupts, subgraphs, or LangSmith-observed agent workflows. ## When to Use - Building multi-step agents with explicit state transitions - Implementing durable, resumable workflows for long-running tasks - Adding human approval or interruption points into agent execution - Modeling branching, loops, retries, and subgraphs explicitly - Using LangSmith to inspect trajectories, state changes, and failures ## Decision Tree ``` Need agent orchestration? +- Mostly linear workflow with simple tool calls? | +- Use plain agent framework first | - Add LangGraph only if state and branching become explicit requirements +- Need durable state across steps or resumes? | - Use LangGraph StateGraph with checkpointing +- Need human approval or editing of state mid-run? | - Use interrupts / human-in-the-loop nodes +- Need reusable workflow segments? | - Use subgraphs with narrow state contracts +- Need production debugging visibility? | - Add LangSmith tracing and run metadata -- Need complex branching and retries? …

How to install
mdr add jnpiyush/agentx/langgraph@sha256:68e9aa132223d823The line at the top of this page pins the label v1.0.0, 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.
