data360-code-extension-generate Skill

Overview

This skill provides a complete workflow for developing, testing, and deploying custom Python code extensions to Salesforce Data Cloud. Code extensions allow you to write Python transformations that read from and write to Data Lake Objects (DLOs) and Data Model Objects (DMOs).

When to Use

• User wants to create a new code extension project
• User needs to test a code extension locally
• User wants to scan code for required permissions
• User needs to deploy a code extension to Data Cloud
• User is working with Data Cloud transformations
• User wants to read/write DLO or DMO data programmatically

Prerequisites Check

Before executing any code extension commands, verify prerequisites:

1. SF CLI with plugin installed

   sf plugins --core | grep data-code-extension
   

   If not installed:

   sf plugins install @salesforce/plugin-data-code-extension
   

2. Python 3.11

   python --version  # Should show 3.11.x
   

3. Data Cloud Custom Code SDK

   pip list | grep salesforce-data-customcode
   

   If not installed:

   pip install salesforce-data-customcode
   

4. Docker running (for deploy only)

   docker ps
   

5. Authenticated org

   sf org display --target-org <org_alias> --json
   

Skill Workflow

Phase 1: Initialize Project

Create a new code extension project with scaffolding.

Commands:

For script-based code extensions (batch transformations):

sf data-code-extension script init --package-dir <directory>

For function-based code extensions (real-time):

sf data-code-extension function init --package-dir <directory>

Required Option:

• --package-dir, -p - Directory path where the package will be created

What it creates:

my-transform/              # Project root
├── payload/               # CRITICAL: This is what --package-dir must point to for deploy
│   ├── entrypoint.py      # Main transformation code
│   └── config.json        # Code extension configuration
├── requirements.txt       # Python dependencies
└── README.md
