What comes back
  For a task: the ask re-posed at the register of the best prior work, with the framing named, invariants,
  constraints with denominators, plan shape, a verification plan that opens with the cheapest falsifying test,
  output shape, definition of done, and the questions only the author can answer, each with a default.
  For a project: a complete brief (intent, non-goals, vocabulary, shape, style regimes, invariants,
  milestones, verification, risks, open questions) ending in a paste-ready AGENTS.md.

Paying
  One free run per address per day from a shared budget that refills continuously (429 names retry_after_s).
