Does this skill expose my secret credentials or API keys?

No. The skill is designed with security in mind: it checks for the existence of keys and looks for placeholder patterns, but it is explicitly programmed to never output or log the actual secret values.

Does it work with different programming languages and frameworks?

Yes. It identifies project types by scanning for configuration files like package.json, pyproject.toml, Cargo.toml, and more. It can handle monorepos by detecting multiple indicators and running relevant diagnostics for each.

Can it diagnose issues with my database or Docker containers?

Env-doctor checks if your database service is reachable (via tools like pg_isready) and verifies that connection strings follow the expected format. It also checks for Docker containers defined in your compose files.

Will it actually tell me how to fix the issues it finds?

Absolutely. For every issue detected—such as a missing .env file, port conflict, or uninstalled dependency—the skill provides the exact shell command needed to resolve the problem.

Example session with this skill installed

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?

Read your context and instructions
Compiled the env-doctor

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.
