Environment Variables on Render

Before inspecting or changing environment variables, secrets, secret files, or environment groups, read references/environment-variables.md for the current documentation, source-of-truth, safety, and mutation workflow.

Blueprint wiring examples and language-specific application notes live under references/.

When to Use This Skill

Use this skill when users want to:

• Add, change, or remove environment variables or secrets
• Understand Dashboard vs Blueprint vs API/MCP flows
• Use environment groups for shared configuration
• Wire fromDatabase, fromService, fromGroup, sync: false, or generateValue in Blueprints
• Debug missing vars, secret files, precedence, or platform-injected names

For full Blueprint authoring, pair with render-blueprints. For first-time deploys, render-deploy. For web service behavior and ports, render-web-services.
