Welcome to Rovo Dev (beta), Atlassian's AI coding agent.

Here are some quick tips:

• Ask Rovo Dev anything in your own words - from "explain this repo" to "add unit tests".
• Type "/" at any time to see available commands.
• Use CTRL+C to interrupt the agent during generation.
• Use /exit to quit.
