refactoring-patterns

This skill conducts automated code reviews focused on quality, testability, and maintainability, prioritizing critical feedback like bugs and security issues. It's designed for use during code reviews, when providing feedback, or when establishing review practices. The tool categorizes feedback by severity and emphasizes asking questions over issuing commands.

This Claude Skill detects codebase bloat by progressively analyzing dead code, duplication, complexity, and documentation issues. It's ideal for quarterly maintenance, pre-release cleanup, or before refactoring when you have sufficient context. Avoid using it during active feature development or when fixing time-sensitive bugs.

This Claude Skill helps developers apply both London (mock-based) and Chicago (state-based) TDD approaches when practicing test-driven development. It guides you to choose the appropriate style based on your context—using Chicago for domain logic and London for code with external dependencies. The skill follows the red-green-refactor cycle and works with specialized testing agents to generate, implement, and refactor tests.

This skill provides a production-tested setup for Content Collections, a TypeScript-first tool that transforms Markdown/MDX files into type-safe data collections with Zod validation. Use it when building blogs, documentation sites, or content-heavy Vite + React applications to ensure type safety and automatic content validation. It covers everything from Vite plugin configuration and MDX compilation to deployment optimization and schema validation.
