render-env-guard

What This Skill Does

The render-env-guard is a mission-critical utility designed to prevent deployment failures caused by configuration drift on the Render platform. It acts as an automated gatekeeper that verifies the state of your service's environment variables before any deployment process begins. By directly interfacing with the Render API, the skill pulls live environment configurations rather than relying on local files, ensuring that what you see is exactly what your production runtime will receive. It performs rigorous validation, checking for the existence of required keys and auditing values for common anti-patterns, such as accidental placeholder strings (e.g., "REPLACE_ME"), unexpanded variable references, or unsafe local development strings like "localhost". By returning specific exit codes, it integrates seamlessly into CI/CD pipelines, allowing you to halt broken deployments before they reach your end users.

Installation

To integrate this skill into your workflow, you can add it via the OpenClaw CLI tool. Run the following command in your terminal:

clawhub install openclaw/skills/skills/daniellummis/render-env-guard

Ensure that you have your RENDER_API_KEY stored in your local environment or secret manager, as this is required for the skill to authenticate with the Render API and perform service lookups.

Use Cases

• Automated CI/CD Gates: Add this skill as a pre-deployment step in your GitHub Actions or GitLab CI workflows to ensure environment variables are valid before triggering a Render build.
• Production Troubleshooting: If your service is returning 5xx errors after an update, use the guard to verify if environment variables were inadvertently unset or misconfigured during the last deployment cycle.
• Onboarding & Migration: When transitioning a service to a new environment, use this tool to quickly verify that all required secret keys are present and correctly mapped, preventing time-consuming trial-and-error debugging.

Example Prompts

1. "OpenClaw, run the render-env-guard for my service 'production-web-api' and make sure the DATABASE_URL and STRIPE_API_KEY are properly configured."
2. "Before I push this new deployment, please check the Render environment for the service ID 'srv-12345' and identify any missing or placeholder variables."
3. "Verify that our staging environment settings are complete, ensuring all keys defined in the required list are non-empty and valid."

Tips & Limitations

This tool is designed for strict validation; it is not meant to manage or edit environment variables. It operates in read-only mode to fetch and validate existing keys. Note that it only checks values as they exist in Render's configuration; it does not scan your local machine's .env files. Ensure your RENDER_API_KEY has the appropriate read permissions for the services you intend to audit. If you encounter issues, verify that your service name matches exactly what appears in the Render dashboard.
