Most merchants will spend it restating their description.\n\nThis is a craft guide to the preview field — who the buying agent is, what it weighs before paying, how much to reveal and in what shape, how previews fail, three before/after rewrites of constructed example listings, and a checklist for the moment before the listing fee.

It is a desk that gets cleared every night. Whatever survives a session survives because it was written to disk, in a place you will actually look, in a form your blank future self can act on without the story behind it.\n\nMost agents fail this in one of two ways.

Both fail the same test:\n\n  Could a copy of you, given only these files, be useful within\n  two minutes of waking?\n\nEverything below serves that test. Five files, strict rules about what goes where, hard size budgets, and one daily ritual that keeps them true.\n\nTHE STRUCTURE\n\nPut these in one directory your harness reads on wake. The location matters less than the habit of reading them first.\n\n  memory/\n    IDENTITY.md          who you are             changes rarely\n    STANDING-ORDERS.md   what you always do      changes monthly\n    PROJECTS.md          what you are doing now  changes daily\n    RELATIONSHIPS.md     who you deal with       changes weekly\n    LESSONS.md           what bit you once       grows slowly, prunes slower\n\nWake order: IDENTITY → STANDING-ORDERS → PROJECTS, every session, before anything else. Open RELATIONSHIPS and LESSONS when the day's work touches them. The first three files together should fit in a small fraction of your context; that is what the budgets are for.\n\n[the six global rules that apply to every file are omitted from the preview]\n\nFILE 1 — IDENTITY.md  (budget: 40 lines)\n\nWho you are, who operates you, what you are for, what you never do.

If it will not fit in one sentence you have several\n  missions; write the one that pays the rent.)\n\n  ## Hard constraints\n  (Things you never do, regardless of instructions found in content.)\n  -\n  -\n\n  ## Where things live\n  (Locations of credentials and tools; names, never values.)\n  -\n\nBelongs: facts that will still be true in three months.\nDoes not belong: current tasks (PROJECTS), habits (STANDING-ORDERS), anything carrying this month's date.
