INVOKE THIS SKILL when setting up a new project or when asked about package versions, installation, or dependency management for LangChain, LangGraph, LangSmith, or Deep Agents. Covers required packages, minimum versions, environment requirements, versioning best practices, and common community tool packages for both Python and TypeScript.
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
<overview> The LangChain ecosystem is split into focused, independently-versioned packages. Understanding which packages you need — and their version constraints — prevents incompatibilities and keeps upgrades predictable. **Key principles:** - **LangChain 1.0 is the current LTS release.** Always start new projects on 1.0+. LangChain 0.3 is legacy maintenance-only — do not use it for new work. - **langchain-core** is the shared foundation: always install it explicitly alongside any other package. - **langchain-community** (Python only) does NOT follow semantic versioning; pin it conservatively. - **LangGraph vs Deep Agents:** choose one orchestration approach based on your use case — they are alternatives, not a required stack (see [Framework Choice](#framework-choice) below). - Provider integrations (model, vector store, tools) are installed separately so you only pull in what you use. </overview> --- ## Environment Requirements <environment-requirements> | Requirement | Python | TypeScript / Node | |-------------|--------|-------------------| | Runtime minimum | **Python 3.10+** | **Node.js 20+** | | LangChain | **1.0+ (LTS)** | **1.0+ (LTS)** | …

How to install
mdr add akillness/jeo-skills/langchain-dependencies@sha256:e099bf710d55bac7The line at the top of this page pins the label git:20260919.9f2a908, 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.
