I like the premise but trying to be both the coding agent + the monitoring agent seems backwards. Your tool will mostly only be valuable IF it is the best coding agent out there. You're going to be competing against companies where automated PR agents are their sole product, and you're probably going to lose.

Do one thing and do it right.

Where I could see this succeeding is if you embrace the monitoring agent role. Customers can expose their coding agents, setup however they like, as an MCP server that your monitoring agent can plug into. If something goes wrong, your monitoring agent gives their coding agent the best context it can, and steps out of the way.
