Cc Devenv Doctor — Development skill for Claude Code

cc-devenv-doctor

One command to take a bare Windows or Mac machine to a working [Claude Code](https://claude.com/claude-code) setup — plus a plugin that keeps diagnosing it afterwards.

Why this exists

This started at an **AI Agentic Engineering for IT** exam.

The material was not the hard part. Getting everyone's machine ready was. Installing git, then Node, then VS Code, then Docker, then the Claude Code CLI — one command at a time, across Windows and Mac at once, with PATH not refreshing, with installers that stop to ask a question nobody in the room knows how to answer. Hours went into that. Hours that were supposed to go into the actual subject.

The frustrating part is that none of it was interesting. It was the same handful of commands every time, in the same order, failing in the same few ways. That is exactly the kind of problem worth solving once and giving away, so nobody else has to spend their morning on it.

So: one script per OS, and a plugin that can tell you what's still broken afterwards.

What it installs

• Git
• Node.js (LTS)
• Bun — required by claude-mem, which doesn't install it for you
• Claude Code CLI (via the official native installer)
• devenv-doctor — the plugin bundled in this repo. Run /devenv-doctor:environment-doctor in Claude Code and it runs the real checks, then tells you exactly what to fix
• Docker Desktop, including WSL2 setup on Windows if it's missing
• VS Code + two extensions: Claude Code and Docker
• mattpocock-skills — a plugin on Anthropic's official marketplace (grilling, TDD, code review, and more)

The last two are examples, not the point

The VS Code extensions and mattpocock-skills are here as **examples of what a ready machine looks like** — not as a claim that these are the right choices fo
