• Engineering Around the Model: Harnesses, Loops, Graphs and the Definition of Done

  Updated:18 Oct, 2026

  The model sets the ceiling; the harness around it decides how close an agent gets. The parts of a harness; loop design (stopping conditions, retries, budgets); graphs and when they beat a loop; and the definition of done as a check the harness runs instead of a claim the model makes. Measured on a small agent: a verifier that checks only where the answer came from, against the same agent without it, with success at each step budget; and what Anthropic's long-running harnesses do about agents that declare victory early.
