langchain-ai: skills, plugins and MCP servers

skill-creator langchain-ai skill Guides agents in scaffolding, validating, and structuring custom skills. It cuts token overhead by separating scripts, docs, and assets. Claude Code CX Codex Cursor +1 1,300installs deep-agents-memory langchain-ai skill A skill that maps where a Deep Agent keeps its files: thread state, a persistent store, or the real disk. Useful once the agent starts dropping context. Claude Code CX Codex Cursor +1 19,000installs langgraph-persistence langchain-ai skill A Claude Code skill for LangGraph persistence: wiring a checkpointer, keeping conversations apart by thread_id, and replaying older graph state. Claude Code CX Codex Cursor +1 18,000installs langgraph-fundamentals langchain-ai skill Skill for writing LangGraph code across platforms. Covers StateGraph, state schemas, nodes, edges, Command, Send, invoke, streaming, and error handling. Claude Code CX Codex Cursor +1 18,000installs langchain-rag langchain-ai skill Equips coding agents with reference RAG implementations in Python and TypeScript using LangChain loaders, splitters, and vector stores. Claude Code CX Codex Cursor +1 17,500installs langchain-fundamentals langchain-ai skill Guides LangChain agent work with create_agent(), tools, and middleware. Use it when you need saved conversation state, approval flows, or error handling. Claude Code CX Codex Cursor +1 17,400installs langgraph-human-in-the-loop langchain-ai skill Skill for building LangGraph workflows that pause and wait for human input. Use it to show agent output, request approval, or validate user responses before continuing. Claude Code CX Codex Cursor +1 17,200installs langchain-middleware langchain-ai skill Adds middleware hooks for LangChain agents: pauses execution before dangerous tool calls, lets a human approve, edit or reject the action, intercepts calls for logging and retry logic. Claude Code CX Codex Cursor +1 16,200installs deep-agents-orchestration langchain-ai skill Guides setup of orchestration in Deep Agents: subagent delegation, todo planning, and human approval interrupts. Claude Code CX Codex Cursor +1 16,100installs langchain-dependencies langchain-ai skill Provides verified package versions and dependency rules for LangChain, LangGraph, and LangSmith. Helps set up clean Python or TypeScript projects without version conflicts. Claude Code CX Codex Cursor +1 16,000installs deep-agents-core langchain-ai skill Skill for building multi-step agents with task planning, context management, and task delegation. Built-in filesystem tools, persistent memory across sessions, and subagent spawning—configure, don't code. Claude Code CX Codex Cursor +1 15,900installs managed-deep-agents langchain-ai skill Guides developers through authoring, testing, and deploying Managed Deep Agents in LangSmith. Useful for setting up code-first agent directories and preparing CLI deployments. Claude Code CX Codex Cursor +1 9,100installs langgraph-cli langchain-ai skill Gives the agent a reference for the langgraph CLI: scaffold a project, run it locally, build an image, deploy it. Claude Code CX Codex Cursor +1 8,900installs swarm langchain-ai skill Fans out independent items across subagents in parallel and aggregates the results. Useful for batch file reviews, labeling, and data extraction. Claude Code CX Codex Cursor +1 8,700installs ecosystem-primer langchain-ai skill Guides framework selection across LangChain, LangGraph, and Deep Agents before writing code. Maps requirements to the right layer, env vars, and quickstarts. Claude Code CX Codex Cursor +1 8,000installs
