I've admittedly not reached for Rovo much in Jira but this could be appealing - have explored using LLMs as a way to jump-start tickets (almost providing boilerplate for the developer to use). Could potentially be a happy medium between when compared to the hands off nature of what Microsoft is doing with Copilot Agents
Atlassian is well positioned to release a coding agent. If they leverage the integration with the rest of their cloud ecosystem it could turn out to be a very cohesive dev loop.
