score-quality

name: score-quality description: Score code migration quality based on coverage and correctness. Evaluates how well target code represents source functionality. license: MIT compatibility: Requires completed migration with source and target code triggers: - migration quality - migration score - coverage score - correctness score

Evaluate migration quality by scoring coverage and correctness for each source-target file pair.

Prerequisite: A migration mapping file must exist (see migration-mapping skill).

See references/scoring-criteria.md for the 1-5 scoring scales.

Output Format

Save scores as a JSON file:

{
  "source_file_1.cbl": {
    "coverage": 4,
    "correctness": 5,
    "justification": "All calculation logic migrated. Tax rounding matches COBOL behavior."
  }
}

Evaluation Process

For each source file and its mapped target files:

1. Identify key functionality in the source

   • Business logic, data operations, control flow, error handling

2. Check coverage in the target

   • Is each function/paragraph represented?
   • Are all data fields and code paths covered?

3. Verify correctness

   • Do calculations produce the same results?
   • Are edge cases handled the same way?

4. Document justification

   • Specific functionality present/missing
   • Known discrepancies

Incremental Scoring

If a score file already exists, update it with new scores rather than replacing it entirely.
