Checks the health of a Claude Code or Codex dev environment (git, Node.js, the Claude Code and Codex CLIs and their login state, VS Code + extensions, Docker, claude-mem, installed plugins) and gives exact fix commands per OS. Use when the user says "check my setup", "is my install broken", "setup isn't working", or asks why claude/codex/docker/git isn't working.
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
This skill runs inside either Claude Code or Codex. Every check below is read-only. In Claude Code they are pre-approved in `allowed-tools`, so run them without stopping to ask. Never assume a result — always run the real command. If a check fails with "Operation not permitted", "permission denied", or a Docker socket connect error while you are running inside Codex, that is Codex's sandbox, not the machine: rerun that one command with escalated permissions before reporting it as broken. ## 1. Run these checks (one at a time) - `git --version` - `node --version` (needs ≥ 20 — claude-mem requires it; current LTS recommended) - `code --version` - `docker --version` and `docker info` (confirms the engine is actually running, not just installed) - Claude Code, if it's installed: - `claude --version` - `claude doctor` — read-only install diagnostics; reports sign-in state, auto-update state, settings-file errors, each with a suggested fix - `claude plugin list` and `claude plugin marketplace list` - Codex, if it's installed: - `codex --version` …

How to install
mdr add killernay/cc-devenv-doctor/environment-doctor@sha256:5d8f3993ce7f1be3The line at the top of this page pins the label git:20261026.3af9e25, 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.
