Skill Tester
Validate, test, and score the quality of skills within the claude-skills ecosystem.
Before & after
Same prompt, same agent — the only difference is the skill.
To know if a skill is production-ready, you should test it manually with a few examples and make sure the output looks reasonable. You'll want to check that it handles different types of input without breaking, and that the formatting is consistent. It's also good to think about edge cases—what happens if someone gives it an empty input or something unexpected? You might also want to review the skill's documentation to make sure the instructions are clear. Overall, if it works well in your manual testing and the documentation is good, it's probably ready. Let me know if you run into any issues.

Skill Tester
Validate, test, and score the quality of skills within the claude-skills ecosystem. Comprehensive meta-skill: structure validation, Python script testing (syntax + imports + runtime + output format), multi-dimensional quality scoring with letter grades and tier classification (BASIC/STANDARD/POWERFUL). Use when authoring a new skill, auditing existing skills for tier promotion, setting up pre-commit hooks for skill quality, or integrating skill QA into CI.
