Frequently asked questions

What is the best Refactoring & code quality skill for AI agents?

The top-rated launch-quality Refactoring & code quality skill for AI agents is code-refactor (grade B), followed by 051-design-two-steps-methods and code-refiner. Skillspace rates 879 Refactoring & code quality skills; 128 are launch-quality.

How does Skillspace rate Refactoring & code quality skills?

Skillspace grades every Refactoring & code quality skill from A to F with a published scoring engine that reads the skill's SKILL.md: architecture and maturity make the score, and a security scan can cap it. In crowded categories, a judge model also compares the strongest contenders side by side, and some skills are tested head-to-head on real tasks against other skills in the same category (including a deliberately weak one) and a no-skill baseline. Launch-quality skills are graded A to C with a clean safety verdict, and not excluded by a quality filter: the filters catch skills our model's safety screen flags for prompt injection, guardrail bypass, harmful content or credential exposure; test fixtures and attack benchmarks; skills written only for the repository they live in; templates and stubs; and near-duplicate variants and copies of other skills. Ratings were last updated on 24 September 2026; the full method is on the methodology page.

Are Refactoring & code quality skills safe to install?

Of the 879 Refactoring & code quality skills Skillspace rates, 857 passed its safety scan with no flag from its model, and 22 are flagged: 4 for review, 7 as risky, 9 as unsafe, 1 as an attack benchmark and 1 as a test fixture. Each skill's page shows its safety verdict. A pass is not a guarantee: the scan reads only the skill's SKILL.md, not the scripts or other files it ships, and looks for patterns such as piping a remote script into a shell, reading credentials or hiding actions from the user. Skills are third-party code that Skillspace indexes but does not host or endorse, so read a skill's source on GitHub before you install it.
