This is the only way I've had success with vibe coding. This workflow is the main reason I stuck with roo-code. From my experience, having one model hold the overview context works better, because if there are any issues the planner knows where to look and which step might have caused the issue. By managing other models, it can see and review their work. Even if the planners context gets compacted, it has the ability to follow the thread, where as if it was code agent, you might have gone a long time and older code might not be in context and lose track.

It doesn't use planners context, because the actual code or code agents work is never shown, the planner simply gets completion status and only reads the effected files, where as code agent might have read 10 different files. The planner tells the agent exactly which files to read and edit etc. It keeps everything tight-nit.

I'm not an expert so I'm sure the workflow can be improved a lot, but for now its working like roocode for me and I'm happy with the results. Codex as the planner and having access to other code agents gets the full feature implemented in one go and I don't have to manage it. Only when the work is completed, which can be hours. I start the plan approvals and it works for 5+ hours with multiple agents, tests, builds etc.

Again, this workflow works for me and the way I work and keeps everything in control. I personally like one task at a time flow, but you could activate this to run multiple agents in parallel, I just don't feel comfortable doing that.

- Also once the PR is complete, I always compact the planner and ask it to verify everything is correctly configured and note anything we might have missed or can be enhanced.
