    🩺 Env Doctor

    by JustHandled Labs

    2

    Fix the 'it works on my machine' problem before you touch the code. Diagnoses local setup failures across Node, Python, Go, and Docker: missing dependencies, broken env vars, port conflicts, stale installs, and 'why won't this run?' sludge, then hands you copy-paste bash fixes.

    About this skill

    What it does

    Env Doctor is a diagnostic tool designed to solve the "it works on my machine" problem. Before you waste time refactoring application code, this skill treats the project as innocent and puts the local environment on trial. It automatically detects your project type (Node, Python, Go, or Docker) and runs a comprehensive health check on runtimes, dependencies, and system configurations.

    Why use this skill

    Manually debugging environment issues is tedious. This skill automates the boring stuff: scanning for missing node_modules, identifying port conflicts, detecting missing environment variables from .env.example, and verifying if services like Postgres or Redis are actually running. Unlike a generic AI prompt, it follows a rigorous diagnostic workflow and provides prioritized, copy-pasteable bash commands to fix discovered issues instantly.

    Supported Tools

    • Runtimes: Node.js, Python, Go, Docker
    • Databases: Postgres, MySQL, Redis
    • Package Managers: npm, pip, go mod
    • System: Port analysis (lsof/Get-NetTCPConnection), file permissions, and .env validation
    debugging
    devops
    node-js
    python

    Env Doctor needs terminal access to run version checks (`node --version`), port checks (`lsof -i :3000`), and service checks (`pg_isready`). File read access reads manifest files (package.json, requirements.txt) and .env files to validate configuration. No write, browser, network, or env var access required.
