GenPark AI Agent Skill - Mutation Coverage Scorer

Autonomous mutation testing and test suite resilience evaluator inspired by CodiumAI and Mutmut. Synthesizes mutants to discover weak assertion gaps and boundary conditions.

Features

• AST Mutant Generation: Generates syntactically valid mutated AST clones.
• Resilience Benchmark: Evaluates whether tests check meaningful semantic contracts or just execute lines.
• Zero External Dependencies: Standard library Python 3.9+.

Quickstart

from client import TestMutationCoverageScorerClient

scorer = TestMutationCoverageScorerClient()
report = scorer.evaluate_mutation_score(code, test_cases)
print("MSI Score:", report["msi"])
