You say
My project won't start and says something about the port. Can you run a health check on my environment and tell me what's wrong?
Your agent does
Identified missing .env fields: STRIPE_KEY and DB_PASSWORD. Found port 3000 occupied by PID 4421. Docker containers for 'redis' are exited. Fix: cp .env.example .env && kill -9 4421.
About this skill
"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.

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.
