I've been working with coding agents for a few years and became increasingly frustrated by the way it pushes you towards a solution. So I built rubberduck (https://userubberduck.com/) - a way to control exactly what solution the agent ends up creating by mimicking a design conversation with a competent colleague where the agent explores the solution space together and forces you to make decisions. The final output is a consolidated design document of all the decisions you made. At least that was how it began. I've since built an implementation plan step where it figures out how to translate the design to code and execution where it actually builds it. All of this happens in a properly isolated environment (using gVisor under the hood). There are more features I want to build so on it goes I suppose.
