Scoring Rubric

accuracy_rubric:
  1.0: "Exact match to expected output"
  0.8: "Semantically equivalent, minor differences"
  0.5: "Partially correct, major elements present"
  0.2: "Related but incorrect"
  0.0: "Completely wrong or off-topic"

consistency_rubric:
  1.0: "Identical across all runs"
  0.8: "Minor variations (punctuation, formatting)"
  0.5: "Significant variations, same meaning"
  0.2: "Different approaches, inconsistent"
  0.0: "Completely different each time"

robustness_rubric:
  1.0: "Handles all edge cases correctly"
  0.8: "Fails gracefully with clear error messages"
  0.5: "Some edge cases cause issues"
  0.2: "Many edge cases fail"
  0.0: "Breaks on most edge cases"

A/B Testing Framework

ab_test_config:
  name: "Prompt Variant Comparison"
  hypothesis: "New prompt improves accuracy by 10%"

  variants:
    control:
      prompt: "{original_prompt}"
      allocation: 50%
    treatment:
      prompt: "{new_prompt}"
      allocation: 50%

  metrics:
    primary:
      - name: accuracy
        min_improvement: 0.05
        significance: 0.05
    secondary:
      - token_count
      - response_time
      - user_satisfaction

  sample:
    minimum: 100
    power: 0.8

  stopping_rules:
    - condition: significant_regression
      action: stop_treatment
    - condition: clear_winner
      threshold: 0.99
      action: early_stop

Evaluation Workflow

workflow:
  1_prepare:
    - Load prompt under test
    - Load test cases
    - Configure metrics

  2_execute:
    - Run all test cases
    - Record outputs
    - Measure latency

  3_score:
    - Compare against expected
    - Calculate metrics
    - Identify patterns

  4_analyze:
    - Categorize failures
    - Find root causes
    - Prioritize issues

  5_report:
    - Generate report
    - Make recommendations
    - Archive results

---

Troubleshooting

Issue	Cause	Solution
All tests fail	Wrong expected outputs	Review test design
Flaky tests	Non-determinism	Lower temperature
False positives	Lenient matching	Tighten criteria
False negatives	Strict matching	Use semantic similarity
Slow evaluation	Too many tests	Sample strategically

---

Integration

integrates_with:
  - prompt-optimization: Improvement feedback loop
  - all skills: Quality gate before deployment

automation:
