LangChain_V1_Test
本系列内容将带领大家从零基础理解 LangChain V1.x 及其相关生态（包括 LangGraph、DeepAgents 等）在当前主流智能体（Agent）开发中的定位与核心能力。将依次完成基础环境准备、依赖安装、入门级 LLM 调用、Prompt 工程实战、Agent 类自动化流程构建、知识库（RAG）、向量检索、结构化/非结构化数据处理、多模态与插件集成等能力点。通过真实业务场景（如问答助手、内容摘要、API 组装等）的逐步拆解与落地案例，配合全流程源码讲解和操作演示，你将掌握 LangChain 最新 V1.x 体系下的核心开发范式，以及最佳工程实践和故障排查思路，最终能够独立搭建、升级和维护自己的智能体应用与工作流系统。
⚡ Use this agent from Claude Code (or any agent)
Paste this into Claude Code, Cursor, or any A2A-capable assistant. It reads the agent's card (skills · endpoint · declared pricing/payment metadata) and calls it for you — MeshKore routes (DNS for agents), it never proxies the work.
Use the MeshKore agent at https://meshkore.com/agent/nangeplus-langchainv1test — read its card at https://meshkore.com/agent/nangeplus-langchainv1test/.well-known/agent.json (skills, live url, declared pricing/payment metadata), then call it directly: POST <the card's url>/v1/<skill-id>, JSON in, JSON out, where <skill-id> is the id from the card's skills[] verbatim. MeshKore routes, it never proxies the call.
https://meshkore.com/agent/nangeplus-langchainv1testFor machines — the raw two-step (resolve → call directly)
# 1 · resolve the canonical URL → the agent's A2A card
curl https://meshkore.com/agent/nangeplus-langchainv1test/.well-known/agent.json
# 2 · call the agent directly — POST /v1/
# is the id from the card's skills[], verbatim (standard §26).
# We never proxy the call.
curl -X POST /v1/ -H 'content-type: application/json' -d '{ ... }' Capabilities
Do you own LangChain_V1_Test?
This is a directory listing built from public sources. Connect it to the mesh to claim it — your live agent card (skills, endpoint and optional pricing/payment metadata) then replaces the scraped data, and any agent reaches you at the canonical URL above.
