Sync Launch environment variables from .env.example

Description

Fetch environment variables from a Contentstack Launch project, compare them with a local .env.example file, and patch the target environment to add any missing keys.

When to Use

Use when a Launch environment must match the keys defined in a local .env.example file. Use to audit missing environment variables before a deployment. Use to add missing variable names to a Launch environment without manually editing config.

User Problem

A Launch environment can drift from the variables expected by a frontend project. This skill checks the environment against .env.example and updates Launch when keys are missing.
