Design Patterns Best Practices

Use this skill when the main question is not just code quality, but pattern choice and pattern fit.

Working Style

1. Start from the problem shape, not from pattern names.
2. Prefer the smallest pattern that clarifies variation or collaboration.
3. Introduce patterns to reduce coupling and change cost, not to impress readers.
4. Keep the domain language more visible than the pattern vocabulary.
5. Remove or avoid patterns that explain less than the code they replace.
