# Quality Evaluation Standards

## Purpose

This document defines the default quality standards used when specifications don't include explicit quality criteria. These standards ensure consistent, fair, and meaningful quality evaluation across all iterations.

## Quality Philosophy

Quality is multi-dimensional:

1. **Technical Excellence**: Does it work well?
2. **Creative Innovation**: Is it interesting?
3. **Specification Adherence**: Does it meet requirements?

All three dimensions matter. A perfect score requires excellence in all areas.

## Scoring Guidelines

### Composite Score Calculation

```
composite_score = (technical * 0.35) + (creativity * 0.35) + (compliance * 0.30)
```

Result is 0-100 scale.

- Worthy of study

**70-79: Good**
- Solid performance
- Meets expectations well
- Quality work
- Above average

**60-69: Adequate**
- Meets basic requirements
- Acceptable quality
- Room for improvement
- Average

**50-59: Needs Improvement**
- Below expectations
- Significant weaknesses
- Requires work
- Below average

**Below 50: Insufficient**

### Evaluation Principles

1. **Objectivity**
   - Base scores on observable evidence
   - Document reasoning for each score
   - Avoid personal bias
   - Apply criteria consistently

2. **Fairness**
   - Evaluate against standards, not other iterations
   - Consider context and constraints
   - Recognize different approaches to quality
   - Don't penalize creative risk-taking unfairly

3. **Constructiveness**
   - Identify specific strengths
   - Point out concrete weaknesses
   - Suggest improvement opportunities
   - Frame feedback positively

4. **Consistency**
   - Use same criteria for all iterations
   - Maintain scoring calibration
   - Avoid evaluation drift
   - Regular calibration checks

5. **Transparency**
   - Document all scoring decisions
   - Explain reasoning clearly
   - Make criteria explicit
   - Enable understanding of scores

## ReAct Integration

Every evaluation should follow ReAct pattern:

**THOUGHT**: Reason about what quality means for this iteration
**ACTION**: Apply evaluation criteria and score
**OBSERVATION**: Analyze results and their implications

Document reasoning at each phase to ensure transparent, thoughtful evaluation.

## Continuous Improvement

These standards should evolve:

1. **Calibration**: Regularly check if scores match actual quality
2. **Refinement**: Adjust criteria based on experience
3. **Expansion**: Add new quality dimensions as needed
4. **Simplification**: Remove criteria that don't differentiate

Quality evaluation is itself a quality process requiring continuous improvement.
