Seconding. In the past months, when using Aider, I've been using the approach of discussing a piece of work (new project, larger change), and asking the model to prepare a plan of action. After possibly some little back and forth, I approve the plan and ask LLM to create or update a specification document for the project and a plan document which documents a sequence of changes broken down into bite-sized tasks - the latter is there to keep both me and the LLM on track. With that set, I can just keep repeatedly telling it to "continue implementation of the plan", and it does exactly that.

Eventually it'll do something wrong or I realize I wanted things differently, which necessitates some further conversation, but other than that, it's just "go on" until we run out of plan, then devising a new plan, rinse repeat.
