configure-env-var

Sets an environment variable by writing it to .atxp/.env.production, which is included in deployments to cloud.atxp.ai.

Usage

/configure-env-var KEY VALUE

Replace KEY with your environment variable name and VALUE with its value.

Examples

Set API keys for external services:

/configure-env-var GOOGLE_ANALYTICS_API_KEY ya29.a0AfH6SMBx...
/configure-env-var GOOGLE_SEARCH_CONSOLE_KEY AIzaSyC...
/configure-env-var DATAFORSEO_API_KEY 12345678-1234-1234-1234-123456789abc

How it works

1. Creates .atxp/.env.production if it doesn't exist
2. Adds or updates the environment variable in KEY=VALUE format
3. Sets file permissions to 600 (owner read/write only)
4. The file will be included in your next /deploy
5. Your deployed agent can access these variables at runtime

Requirements

• Bash 3.2+ (default on macOS and most Linux distributions)
• Write access to current directory

Value Handling

• Empty values: Not allowed. Use /remove-env-var to delete variables.
• Values with spaces: Fully supported (e.g., "Hello World")
• Values with special characters: Supported including =, :, /, etc.
• Multiline values: Not supported. Use base64 encoding if needed.

Implementation

#!/bin/bash

# Parse arguments
if [ "$#" -lt 2 ]; then
    echo "Usage: /configure-env-var KEY VALUE"
    echo "Example: /configure-env-var API_KEY abc123"

# Validate key format (alphanumeric and underscore only)

    echo "Error: KEY must start with a letter or underscore and contain only alphanumeric characters and underscores"
