LangGraph is a separate, lower-level runtime built by the\nsame project specifically for agents whose control flow is not a single\nlinear loop — it models the agent as an explicit graph of nodes and edges,\nsupports cycles (a node can route back to an earlier node), and adds two\ncapabilities `AgentExecutor` does not have out of the box: durable\ncheckpointed state (so a run can pause, crash, and resume from its last\ncheckpoint) and first-class human-in-the-loop interrupts (a graph can pause\nat a named node until a human approves, edits, or rejects the pending\nstate). This skill covers choosing between plain LangChain composition,\n`AgentExecutor`, and LangGraph, and operating LangGraph's persistence and\ninterrupt features correctly. It is a framework-specific complement to\n[agent-architecture-design](../agent-architecture-design/SKILL.md), which\ncovers the underlying control-flow patterns (ReAct loop, plan-and-execute,\nfinite-state/graph) in a vendor-neutral way — LangGraph is one concrete\nruntime that implements the finite-state/graph pattern described there. For\ntool access, LangChain/LangGraph agents can call tools defined directly in\nPython or exposed via an MCP server; see\n[mcp-server-development](../mcp-server-development/SKILL.md) for building\nthe tool-serving side, which this skill treats as an external dependency\nrather than repeating.\n\n## When to use\n\n- Deciding whether a task needs plain LangChain chain composition (a fixed\n  pipeline, no branching), `AgentExecutor` (a single ReAct-style tool-calling\n  loop), or a LangGraph graph (multi-step, branching, cyclical, or needing\n  persistence/human approval).\n- Building an agent whose steps depend on prior results in ways a single\n  linear chain can't express — retries, conditional branches, or loops back\n  to an earlier step.\n- Adding durable state to a LangChain/LangGraph agent so a long-running or\n  multi-session workflow survives a process restart or crash mid-run.\n- Adding a human-in-the-loop approval checkpoint before an irreversible tool\n  call in an existing LangGraph graph.\n- An agent built with `AgentExecutor` loses context, re-does completed work,\n  or can't be paused/resumed, and the team is evaluating migrating it to\n  LangGraph.\n- Debugging a LangGraph graph that loops indefinitely, gets stuck at an\n  interrupt, or fails to restore state correctly from a checkpoint.\n\n## Prerequisites & environment\n\n- Python (LangChain/LangGraph's primary, most mature ecosystem) or\n  JavaScript/TypeScript (`langchain`/`langgraph` npm packages, closely\n  mirroring the Python API but with some feature lag) — pick one and check\n  current package versions before starting, since both projects have had\n  breaking changes across major versions (notably the LangChain 0.1 → 0.2/0.3\n  restructuring that split core, community, and partner packages).\n- An LLM provider integration package (e.g. `langchain-anthropic`,\n  `langchain-openai`) installed separately from `langchain-core` — recent\n  LangChain versions moved provider-specific code out of the core package.\n- For LangGraph persistence: a checkpointer backend — the in-memory\n  `MemorySaver` for local development/testing only (state is lost on\n  process exit), or a durable checkpointer (SQLite, Postgres, or a\n  managed backend) for anything that must survive a restart.\n- Tool definitions the agent will call, either as plain Python functions\n  decorated with LangChain's `@tool`, or proxied from an MCP server via an\n  MCP-to-LangChain adapter — confirm which integration path your LangChain\n  version currently supports before assuming API shape.\n- Clarity on which parts of the workflow are genuinely cyclical/branching\n  (justifying LangGraph) versus a fixed sequence (better served by a plain\n  LCEL chain) — reach for LangGraph only once a chain's limitations are\n  concrete, mirroring the \"justify the split\" discipline in\n  [agent-architecture-design](../agent-architecture-design/SKILL.md).\n\n## Step-by-step guidance\n\n1. **Start with the simplest abstraction that fits the task's shape.** A\n   fixed sequence (retrieve → prompt → parse) is a plain LCEL chain:\n   ```python\n   from langchain_core.prompts import ChatPromptTemplate\n   from langchain_core.output_parsers import StrOutputParser\n   from langchain_anthropic import ChatAnthropic\n\n   prompt = ChatPromptTemplate.from_messages([\n       (\"system\", \"Summarize the following ticket in one sentence.\"),\n       (\"human\", \"{ticket_text}\"),\n   ])\n   model = ChatAnthropic(model=\"claude-sonnet-4-5\", temperature=0)\n   chain = prompt | model | StrOutputParser()\n   result = chain.invoke({\"ticket_text\": ticket_body})\n   ```\n   No loop, no tool calls, no branching — a chain is the right tool and\n   adding `AgentExecutor` or LangGraph here is unjustified complexity.\n\n2. **Use `AgentExecutor` only for a single, bounded ReAct-style loop** with\n   no need for persistence, human interrupts, or branching beyond\n   tool-call/no-tool-call:\n   ```python\n   from langchain.agents import AgentExecutor, create_tool_calling_agent\n   from langchain_core.tools import tool\n\n   @tool\n   def search_tickets(query: str) -> str:\n       \"\"\"Search support tickets by keyword. Returns matching ticket IDs.\"\"\"\n       return ticketing_backend.search(query)\n\n   agent = create_tool_calling_agent(model, [search_tickets], prompt)\n   executor = AgentExecutor(\n       agent=agent, tools=[search_tickets],\n       max_iterations=8, max_execution_time=60,   # bound the loop explicitly\n   )\n   result = executor.invoke({\"input\": \"find open billing tickets\"})\n   ```\n   `max_iterations`/`max_execution_time` are `AgentExecutor`'s equivalent of\n   the hard iteration cap and timeout described in\n   [agent-architecture-design](../agent-architecture-design/SKILL.md) — set\n   both explicitly; the defaults are more permissive than most production\n   use cases want.\n\n3. **Move to LangGraph once the task needs cycles, branching, persistence,\n   or a human checkpoint.** Model the agent as a typed state object and a\n   graph of nodes:\n   ```python\n   from typing import TypedDict, Annotated\n   from langgraph.graph import StateGraph, END\n   from langgraph.checkpoint.memory import MemorySaver\n\n   class TicketState(TypedDict):\n       ticket_id: str\n       category: str\n       draft_reply: str\n       approved: bool\n\n   def triage(state: TicketState) -> TicketState:\n       category = classify(state[\"ticket_id\"])\n       return {**state, \"category\": category}\n\n   def draft(state: TicketState) -> TicketState:\n       reply = generate_draft(state[\"ticket_id\"], state[\"category\"])\n       return {**state, \"draft_reply\": reply}\n\n   def route_after_triage(state: TicketState) -> str:\n       return \"escalate\" if state[\"category\"] == \"legal\" else \"draft\"\n\n   graph = StateGraph(TicketState)\n   graph.add_node(\"triage\", triage)\n   graph.add_node(\"draft\", draft)\n   graph.add_node(\"escalate\", lambda s: {**s, \"approved\": False})\n   graph.set_entry_point(\"triage\")\n   graph.add_conditional_edges(\"triage\", route_after_triage, {\"draft\": \"draft\", \"escalate\": \"escalate\"})\n   graph.add_edge(\"draft\", END)\n   graph.add_edge(\"escalate\", END)\n\n   app = graph.compile(checkpointer=MemorySaver())\n   ```\n   This is the finite-state/graph pattern from\n   [agent-architecture-design](../agent-architecture-design/SKILL.md)\n   expressed directly in LangGraph's API — nodes are states, edges (plain\n   or conditional) are transitions.\n\n4. **Add a human-in-the-loop interrupt at the highest-leverage node**, not\n   everywhere, using `interrupt_before`/`interrupt_after` at compile time:\n   ```python\n   app = graph.compile(\n       checkpointer=MemorySaver(),\n       interrupt_before=[\"send_reply\"],   # pause here every run until resumed\n   )\n\n   config = {\"configurable\": {\"thread_id\": \"ticket-8842\"}}\n   app.invoke(initial_state, config=config)   # runs up to send_reply, then pauses\n\n   # ... a human reviews the checkpointed state out-of-band ...\n\n   app.invoke(None, config=config)            # resumes from the paused checkpoint\n   ```\n   Passing `None` as input on resume is deliberate — it tells LangGraph to\n   continue from the last checkpoint rather than starting a new run; passing\n   a real input restarts the thread instead.\n\n   > **Warning:** compiling a graph that reaches an irreversible-write node\n   > (sending a message, executing a payment, deleting a resource) with no\n   > `interrupt_before` on that node means it will execute automatically the\n   > first time the graph reaches it, with no human checkpoint at all. Do\n   > not rely on prompt wording alone to prevent an irreversible action —\n   > gate it structurally with `interrupt_before`, the same discipline\n   > described for any irreversible tool in\n   > [agent-architecture-design](../agent-architecture-design/SKILL.md).\n\n5. **Choose a checkpointer backend deliberately for the deployment target.**\n   `MemorySaver` is fine for local development and tests; anything\n   long-running or multi-process needs a durable checkpointer:\n   ```python\n   from langgraph.checkpoint.sqlite import SqliteSaver\n   # or, for production multi-instance deployments:\n   # from langgraph.checkpoint.postgres import PostgresSaver\n\n   with SqliteSaver.from_conn_string(\"checkpoints.db\") as checkpointer:\n       app = graph.compile(checkpointer=checkpointer)\n   ```\n   Every checkpointed run needs a stable `thread_id` in `config`; reusing a\n   `thread_id` across unrelated tasks corrupts that thread's history.\n\n6. **Bound cycles explicitly.** A conditional edge that can route back to an\n   earlier node (e.g. `draft -> review -> draft` on rejection) needs an\n   explicit counter in state and a hard cap, or a rejection loop can run\n   indefinitely:\n   ```python\n   def route_after_review(state: TicketState) -> str:\n       if state.get(\"revision_count\", 0) >= 3:\n           return \"escalate\"          # fail closed after 3 rejected drafts\n       return \"draft\" if not state[\"approved\"] else END\n   ```\n\n7. **Stream intermediate state for observability**, rather than only\n   consuming the final result — both `AgentExecutor` and LangGraph support\n   streaming (`.stream()`/`.astream()`), which surfaces each tool call and\n   state transition as it happens, matching the \"instrument every loop\n   iteration\" guidance in\n   [agent-architecture-design](../agent-architecture-design/SKILL.md).\n\n8. **Compose multiple LangGraph graphs for multi-agent topologies** rather\n   than hand-rolling a supervisor loop, when the task genuinely needs\n   multiple specialized roles — a compiled graph can itself be a node in a\n   parent graph. Confirm this split is justified per\n   [multi-agent-orchestration](../multi-agent-orchestration/SKILL.md) before\n   introducing it; LangGraph makes multi-agent easy to wire, not automatically\n   the right call.\n\n## Best practices\n\n- Default to the least powerful ","tagline":"Guides building LLM applications with LangChain's chain/agent abstractions and, for stateful multi-step agents, LangGraph's graph-based orchestration (nodes, edges, cycles, checkpointed persistence, human-in-the-loop interrupts).

Preserve the core workflow, adapt paths to this repo, and keep the rule scoped to tasks where it is relevant. Skill purpose: Guides building LLM applications with LangChain's chain/agent abstractions and, for stateful multi-step agents, LangGraph's graph-based orchestration (nodes, edges, cycles, checkpointed persistence, human-in-the-loop interrupts).
