Environment Variable Handler

Core Rules

NO .env.example: Do not create this file. Use .env as the template.
Secrets in .env.local: Actual sensitive values must live in .env.local (git-ignored).
Placeholders: Every variable in .env.local MUST have a corresponding entry in .env.
- If sensitive: KEY=""
- If public/common: KEY="default_value"

Instructions

1. Adding a New Sensitive Variable

When you need to add a secret (e.g., REPLICATE_API_TOKEN):

Update .env: Add the variable with an empty string value.
```
# .env
REPLICATE_API_TOKEN=""
```
Ask the User: Explicitly request the user to add the actual value to their local secrets file.

"I have added REPLICATE_API_TOKEN to your .env file. Please open .env.local and add the actual token: REPLICATE_API_TOKEN=your_token_here"

2. Adding a Non-Sensitive Variable

When adding a public or configuration variable (e.g., NEXT_PUBLIC_APP_URL):

Update .env: Add the variable with its default or development value.
```
# .env
NEXT_PUBLIC_APP_URL="http://localhost:3000"
```

3. Reading Variables

Server-side: process.env.KEY
Client-side: process.env.NEXT_PUBLIC_KEY
