The Agent Skills Directory

[SAFE]: The skill provides comprehensive instructions for integrating mutation testing into a development workflow. It correctly identifies and recommends well-established, industry-standard tools for different language ecosystems, such as StrykerJS for JavaScript/TypeScript and mutmut or cosmic-ray for Python.
[SAFE]: The instructions emphasize safe and efficient practices, such as scoping initial runs to critical business logic, using incremental testing modes to minimize resource consumption, and establishing CI gates based on measured baselines rather than arbitrary thresholds.
[SAFE]: No malicious patterns, such as prompt injection, unauthorized data access, obfuscation, or persistence mechanisms, were detected within the skill's instructions. The skill operates within the expected context of a developer agent helping to maintain a local codebase.
