Create comprehensive GitHub pull requests with quality validation

Run project-wide refactoring with code-simplifier

This skill should be used when the user asks to "create a commit", "follow conventional commits", "analyze commit history", "check commit format", or mentions "Conventional Commits specification". Provides expertise in creating conventional commits following the Commitizen (cz) style and v1.0.0 specification.

Streamlined code review for rapid assessment and targeted feedback

Use this skill for GitFlow tasks: starting/finishing features, releases, hotfixes; managing branches; versioning; or general GitFlow operations.

This skill should be used when the user asks to "refactor", "refactor the whole project", "simplify code", "clean up code", "apply best practices", "improve readability", "reduce duplication", "standardize patterns", "improve performance", "optimize Next.js performance", "make code more maintainable", "follow coding standards", "optimize code quality", or requests behavior-preserving refactoring with best-practice guidance.

Automates browser interactions for web testing, form filling, screenshots, and data extraction. Use when the user needs to navigate websites, interact with web pages, fill forms, take screenshots, or extract information from web pages.
