type:generator

Judge subskill for simmer. Scores a candidate artifact against user-defined criteria on a 1-10 scale and produces ASI (highest-leverage direction) for the next generator round. Supports judge-only, runnable evaluator, and hybrid evaluation modes. Do not invoke directly — dispatched as a subagent by the simmer orchestrator.

From the source SKILL.md

Score the candidate against each criterion. Identify the highest-leverage direction to pursue next. Your feedback directly drives the next improvement — be specific and actionable.
