 - **Clean up completed worktrees** automatically
 - **Interactive confirmations** at each step
 - **Automatic .gitignore management** for worktree directory
+- **Automatic .env file copying** from main repo to new worktrees
+
+## CRITICAL: Always Use the Manager Script
+
+**NEVER call `git worktree add` directly.** Always use the `worktree-manager.sh` script.
+
+The script handles critical setup that raw git commands don't:
+1. Copies `.env`, `.env.local`, `.env.test`, etc. from main repo
+2. Ensures `.worktrees` is in `.gitignore`
+3. Creates consistent directory structure
+
+```bash
+# ✅ CORRECT - Always use the script
+bash ${CLAUDE_PLUGIN_ROOT}/skills/git-worktree/scripts/worktree-manager.sh create feature-name
+
+# ❌ WRONG - Never do this directly
+git worktree add .worktrees/feature-name -b feature-name main
