env-doctor

"It works on my machine" ends here. This skill runs a systematic health check on any project: verifies runtime versions match requirements, checks for missing or conflicting dependencies, diffs your .env against .env.example to find missing variables, checks if databases and services are running, detects port conflicts, and verifies build artifacts exist. It reports every issue with the exact command to fix it. Works with Node.js, Python, Rust, Go, Ruby, and Docker projects. Never prints your secret values.
