8.4/10 — installs cleanly 5/5, triggers reliably 5/5, output vs. baseline 7/10, docs & honesty 4/5.

How do I install Dive Into LangGraph?

Copy the install command from this page, run it in your terminal, and restart Claude Code. Skills live in ~/.claude/skills/ (global) or .claude/skills/ inside a project.

Can I use Dive Into LangGraph with Cursor, Copilot, Gemini CLI, Codex or other AI tools?

The SKILL.md format is native to Claude (Claude Code, Desktop, claude.ai). The instructions inside adapt to other assistants: Cursor rules, GitHub Copilot instructions, Windsurf rules, Custom GPTs, AGENTS.md for OpenAI Codex, and GEMINI.md for Google Gemini CLI — our conversion guides cover each, and the free converter on the tools page does the wrapping for you.

Test report

Verdict: Tested · Works
Score: 8.4/10
Tested: Jul 17, 2026
Environment: Claude Code 2.x (agent harness)
Upstream re-checked: Aug 10, 2026 · fb6fb62

Built the skill's exact create_agent + ToolRuntime[Context] permission pattern against a freshly installed langgraph 1.2.9 / langchain 1.3.14: it compiled into a valid 4-node agent graph, whereas a from-memory baseline reaches for the now-legacy langgraph.prebuilt.create_react_agent. The reference API is current and verified, though the 11 chapters are in Chinese, which the description does not warn about.
