To keep environment variables synchronized across multiple project files, this Skill provides a workflow to propagate updates through .env.example, server.js, docker-compose.yml, and Dockerfile, reducing deployment misconfigurations.

The best way to document environment variables is by updating docs/ENVIRONMENT-VARIABLES.md and CLAUDE.md alongside code changes, ensuring centralized documentation accurately reflects current variables required by server.js.

To safely update a PORT environment variable for deployment, you must align configurations across .env.example, server.js, docker-compose.yml, and Dockerfile, outlining required defaults and validation steps to prevent rollout errors.

Yes, the workflow supports Docker by requiring updates to docker-compose.yml and Dockerfile when introducing new environment variables, ensuring containerized deployment configurations remain aligned with application code.

You need to update .env.example immediately when adding new environment variables to ensure required defaults are visible, enforcing a safe workflow by validating steps and aligning centralized documentation before deployment.
