Lets you read and modify Railway environment configuration through Claude Code. You can inspect and change environment variables, tweak build settings, and adjust service deployment parameters without leaving your editor. Useful when you're iterating on config during development or debugging deployment issues and don't want to context switch to the Railway dashboard. Part of the larger use-railway skill that handles the full Railway stack, so this environment piece fits into a broader workflow around projects, services, and deployments. The granular focus makes sense if you're already comfortable with Railway's resource model and just need quick access to environment-level controls.
