# Case Study: Evaluator-Loop Skill Synthesis

## Scenario

Goal: create a skill where one pass is not enough and quality improves through critique and revision.

## Input collection approach

This case collected:

1. examples of first-draft failures
2. existing review rubrics or acceptance criteria
3. evidence that critique materially improves output
4. stopping rules to avoid endless loops

## Coverage matrix used

Required dimensions tracked during synthesis:

1. rubric quality
2. feedback-to-edit mapping
3. loop stop conditions
4. evidence retention between rounds

## Synthesized artifacts produced

The resulting skill references included:

1. first-draft to critique to revision example
2. rubric reference
3. max-loop or plateau rule
4. acceptance checklist

## What made this high quality

1. the rubric was explicit
2. the loop had a clear stopping rule
3. the revision process produced measurable improvement rather than vague repetition
