Extended LangChain row with Deep Agents core/memory/orchestration, middleware/HITL, dependency pinning, and Managed Deep Agents ops. Confirm source-list slugs before apply.

Quick Start

Install:

npx skills add langchain-ai/langchain-skills --skill ecosystem-primer --skill langchain-fundamentals --skill langgraph-fundamentals --skill langgraph-human-in-the-loop --skill langgraph-persistence --skill langchain-rag --skill deep-agents-core --skill deep-agents-memory --skill deep-agents-orchestration --skill langchain-middleware --skill langchain-dependencies --skill managed-deep-agents -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode

Use: /ecosystem-primer

Works with Claude Code, Gemini CLI, OpenCode, and other agentskills.io-compatible agents.

Curated external (hand-maintained)

Composed compose-external-wave-4 using authoring SSOT (docs/src/authoring/skills/ecosystem-primer.mdx) + research. Do not run wagents docs generate on this file (HAND-MAINTAINED sentinel). Run external-skill-auditor before using in production or promoting.

What It Does

Part of official langchain-ai/langchain-skills (early dev, ~800 stars). ecosystem-primer: start-here for choosing LangChain vs LangGraph vs Deep Agents, env setup, next skills. langchain-fundamentals: agents via create_agent, tools, structured output, middleware. langchain-middleware: HITL approval, custom middleware, Command resume. langchain-rag: RAG (loaders, embeddings, vector stores). langchain-dependencies: version pinning ref for py/ts.

Harness Coverage

Targets verified harnesses: antigravity, claude-code, codex, crush, cursor, gemini-cli, github-copilot, grok, opencode.

Portable multi-harness install command:

npx skills add langchain-ai/langchain-skills --skill ecosystem-primer --skill langchain-fundamentals --skill langgraph-fundamentals --skill langgraph-human-in-the-loop --skill langgraph-persistence --skill langchain-rag --skill deep-agents-core --skill deep-agents-memory --skill deep-agents-orchestration --skill langchain-middleware --skill langchain-dependencies --skill managed-deep-agents -y -g -a antigravity claude-code codex crush cursor gemini-cli github-copilot grok opencode
