score-quality skillA
score-quality is agent-read markdown (skill) from openhands/extensions: Score code migration quality based on coverage and correctness. Evaluates how well target code represents source functionality..
Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.
What the file says
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](references/scoring-criteria.md) for the 1-5 scoring scales.
## Output Format
Save scores as a JSON file:
```json
{
"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.Read the whole file at its exact version.
How to install
mdr add openhands/extensions/score-quality@git:20260306.cebd78bmdr add openhands/extensions/score-quality@sha256:c0a0955e32eff9c6Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
