junit-core

Quick Review

This skill provides well-structured JUnit 5 testing standards with clear AAA patterns, coverage requirements, and test organization guidelines. The description adequately covers capabilities, and the workflow provides good task knowledge with references to detailed standards files. Structure is clean with a reference-mode approach that loads standards on-demand. However, novelty is limited—JUnit 5 testing patterns are well-documented online and a CLI agent could reasonably generate similar guidance without this skill, especially for standard AAA patterns and basic test structure. The skill is most valuable for enforcing consistent standards across a team rather than solving complex or obscure testing challenges.
