Render Env Guard

Use this skill when a deployment is failing because environment variables are missing, placeholder values leaked from templates, or service selection is ambiguous.

What this skill does

• - Resolves a Render service by ID or name
• Pulls service environment variables through Render API
• Validates required keys exist and are non-empty
• Flags suspicious values (template placeholders, localhost DB URLs, unexpanded ${VAR} refs)
• Exits non-zero on any blocking issue so CI/deploy scripts can fail fast

When to use

• - Before render deploy / render blueprint updates
• After onboarding a new environment
• When runtime is showing config-related 5xx errors

Inputs

• - RENDER_API_KEY (required)
• one of:

• - optional:

Run

CODEBLOCK0

or with explicit values:

CODEBLOCK1

Output contract

• - Prints a short report with PASS/INLINECODE11
• Returns exit code 0 when all required keys are valid
• Returns exit code 1 when any key is missing/invalid or service lookup fails

Notes

• - This checker is intentionally strict to prevent bad deploys.
• It validates values at the service level (what Render will inject at runtime), not local .env files.
