• /setup-branch https://mycompany.atlassian.net/browse/PROJ-123 - Create branch from JIRA URL

Instructions:

1. Check prerequisites:
   • Atlassian CLI (acli): Run acli auth status to check if the CLI is installed and authenticated.
     • If the command is not found, display the following message and STOP:

       ## Missing Prerequisite: Atlassian CLI
       
       The `acli` command is not installed. This skill requires the Atlassian CLI to fetch JIRA issue details.
