Nothing says what is left

The description says what the task is and the wrapup says what it became. Neither says which parts are finished, and reading that out of the two is guesswork. Break the work into steps, write the detail of each in markdown, and tick them as you review them: the next session opens on the ones still open, in full. A step starts as a draft, off the list, until you promote it.

Or have Claude propose them: Plan here above opens a session on it, or give this to one you have. It reads the description, the wrapup and the code, and puts each step it suggests on a Drafts shelf here, for you to reword and promote. It builds nothing.
