# 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:

- `RENDER_SERVICE_ID`

- `RENDER_SERVICE_NAME`

optional:

- `RENDER_API_BASE_URL` (default `https://api.render.com/v1`)

- `REQUIRED_ENV_KEYS` (comma-separated, default: `DATABASE_URL,DIRECT_URL,SHADOW_DATABASE_URL,NEXT_PUBLIC_APP_URL`)

Run

bash scripts/check-render-env.sh

or with explicit values:

RENDER_SERVICE_NAME=my-service \
REQUIRED_ENV_KEYS="DATABASE_URL,NEXT_PUBLIC_APP_URL,STRIPE_SECRET_KEY" \
bash scripts/check-render-env.sh

Output contract

Prints a short report with `PASS`/`FAIL`

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.
