Render Deploy Diff

# Render Deploy Diff

Use this skill before deploy to compare required environment keys with what is currently configured on a Render service.

What this skill does - Resolves a target Render service by `RENDER_SERVICE_ID` or `RENDER_SERVICE_NAME` - Reads required env keys from `REQUIRED_ENV_KEYS` or local env template files - Fetches configured env keys from Render API - Prints two drift sets: - required but missing on Render - present on Render but not required locally - Exits non-zero when required keys are missing on Render

Inputs - `RENDER_API_KEY` (required unless using mock JSON) - one of: - `RENDER_SERVICE_ID` - `RENDER_SERVICE_NAME` - optional: - `RENDER_API_BASE_URL` (default `https://api.render.com/v1`) - `REQUIRED_ENV_KEYS` (comma-separated explicit required keys) - `REQUIRED_ENV_FILES` (comma-separated files to parse, default `.env.example,.env.production`) - `RENDER_ENV_VARS_JSON_PATH` (path to saved Render env-var API JSON for offline testing)

Run

```bash bash scripts/render-deploy-diff.sh ```

With explicit required keys:

```bash RENDER_SERVICE_NAME=my-service \ REQUIRED_ENV_KEYS="DATABASE_URL,DIRECT_URL,SHADOW_DATABASE_URL,NEXT_PUBLIC_APP_URL" \ bash scripts/render-deploy-diff.sh ```

Offline test with saved API response:

```bash REQUIRED_ENV_KEYS="DATABASE_URL,NEXT_PUBLIC_APP_URL" \ RENDER_ENV_VARS_JSON_PATH=./fixtures/render-env-vars.json \ bash scripts/render-deploy-diff.sh ```

Output contract - Prints service identity, required key count, remote key count, and drift summary - Returns exit code `0` when all required keys exist on Render - Returns exit code `1` when required keys are missing or inputs are invalid
