A messy chat should be restarted with a clear handover instead of repaired forever. Too many corrections mix old goals, wrong assumptions and new requirements.
Extract the valid state, name rejected paths and start a new chat in the same space.
Start with a narrow boundary: which website, space, file, recipient or decision is affected? This makes the task reviewable instead of turning it into a broad catch-all request.
A useful work order is: “Clean up this chat into valid decisions, false assumptions, rejected variants, relevant files and a new start prompt.” For important cases, add that uncertainties must be marked visibly instead of being filled in silently.
Pay special attention to current work status, confirmed decisions and open questions. These points decide whether the result is only useful for the moment or can be found, checked and continued by the team later.
Do not keep correcting when the foundation of the conversation is confused.
A clean restart saves time while preserving project context.
