## What it does

This skill manages the lifecycle of Salesforce Data Cloud code extensions written in Python. It supports batch scripts and real-time functions reading from or writing to DLO and DMO resources using the `salesforce-data-customcode` SDK. The assistant handles project initialization, schema verification, and local test runs against an active org.

The scan phase inspects `payload/entrypoint.py` to map out read and write permissions, then updates `config.json` and `requirements.txt`. During deployment, the `--package-dir` flag must point directly to `./payload` rather than the project root. Missing this directory target causes deployment failures.

Prerequisites include Python 3.11, SF CLI 2.0.0 or higher with `@salesforce/plugin-data-code-extension`, and an authenticated Salesforce org. Docker 20.0.0 or newer is strictly required for deployment. Local testing runs without Docker.

## Requirements
- Works with: Docker, Salesforce

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill data360-code-extension-generate -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/data360-code-extension-generate/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/data360-code-extension-generate/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill data360-code-extension-generate -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/data360-code-extension-generate/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill data360-code-extension-generate -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/data360-code-extension-generate/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install forcedotcom/sf-skills data360-code-extension-generate
```

2. **Manually: put the files in place**
- File: `.github/skills/data360-code-extension-generate/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill data360-code-extension-generate -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/forcedotcom/sf-skills --path skills/data360-code-extension-generate
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/data360-code-extension-generate/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add forcedotcom/sf-skills --skill data360-code-extension-generate -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/forcedotcom/sf-skills/tree/HEAD/skills/data360-code-extension-generate/SKILL.md

## When to use it
- scaffold Salesforce Data Cloud Python extension projects
- scan `entrypoint.py` to populate permissions in `config.json`
- test data transformations locally against a live org
- deploy batch scripts and real-time functions with Docker

## Example prompts
- Initialize a script code extension in directory my-transform
- Scan payload/entrypoint.py to generate config.json permissions
- Run payload/entrypoint.py locally against target org my-org

# 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**
   ```bash
   sf plugins --core | grep data-code-extension
   ```
   If not installed:
   ```bash
   sf plugins install @salesforce/plugin-data-code-extension
   ```

2. **Python 3.11**
   ```bash
   python --version  # Should show 3.11.x
   ```

3. **Data Cloud Custom Code SDK**
   ```bash
   pip list | grep salesforce-data-customcode
   ```
   If not installed:
   ```bash
   pip install salesforce-data-customcode
   ```

4. **Docker running** (for deploy only)
   ```bash
   docker ps
   ```

5. **Authenticated org**
   ```bash
   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):
```bash
sf data-code-extension script init --package-dir <directory>
```

For **function-based** code extensions (real-time):
```bash
sf data-code-extension function init --package-dir <directory>
```

**Required Option:**
