Salesforce CLI Development Deployment Guide

Core Principles

CRITICAL: Use the modern sf CLI (not legacy sfdx) for all Salesforce operations. This skill focuses on development deployments for iterative coding workflows, not production migrations or CI/CD pipelines.

Understanding Deployment Commands

❌ CRITICAL MISTAKE TO AVOID

NEVER use deploy start to check deployment status!

# ❌ WRONG - Starting new deployment when you meant to check status
sf project deploy start --source-dir force-app
# This starts a NEW deployment, doesn't check existing one!

# ✅ CORRECT - Check status of existing deployment
sf project deploy report --job-id <deployment-id>
