🩺 Env Doctor

What it does

Env Doctor guides a local, read-only diagnosis when an app works on one machine but not another. It checks project type, runtime versions, dependencies, required environment-variable key names, local port ownership, Docker configuration, and service health across Node.js, Python, Go, and Docker projects.

Why use this skill

Environment failures often look like application bugs. Env Doctor follows a prioritized workflow so you can identify the likely setup issue before changing code. It never asks for secret values, never prints .env contents, and does not kill processes or modify project files blindly. Findings include the evidence checked, the likely cause, and shell-specific next steps.

Cross-platform fixes

Commands are matched to the user's shell: PowerShell on Windows, or Bash-compatible commands on macOS and Linux. Port checks identify the owning process before any stop action is suggested.

Supported tools

• Runtimes: Node.js, Python, Go, Docker
• Services: Postgres, MySQL, Redis
• Package managers: npm, pip, go mod
• System checks: dependency state, key-only environment validation, port ownership, Docker configuration, and local service health
