What comes back


For a task (a document, a script, a fix, an analysis): the ask re-posed at the register of the best prior work: the framing named, invariants, constraints with their denominators, the plan shape, a verification plan that opens with the cheapest test that would prove it wrong, the output shape, a definition of done, and the questions only you can answer, each with a default.


For a project (a product, a system, a repo, a campaign): a complete brief: intent, non-goals, vocabulary, architecture, style regimes, invariants with their checks, milestones from a walking skeleton up, risks from a premortem, and an AGENTS.md ready to paste into the repo root.
