Browse reusable Agent Skills, each with a clear purpose and practical guidance.
Practical regex patterns for common tasks - validation, extraction, replacement - with language-specific syntax differences and ready-to-use recipes. Use when the user asks about regex cheatsheet, related techniques, best practices, or needs guidance in this domain. Do NOT use when the request is outside the scope of regex cheatsheet or requires a different specialized skill.
Regular expression expert covering syntax reference, common patterns, performance optimization, lookaround assertions, named groups, language-specific flavors, and testing strategies. Use when the user asks about regex master, regex master best practices, or needs guidance on regex master implementation. Do NOT use when the user needs a different specialized skill or is asking about an unrelated technology domain.
Guides expert-level responsive design patterns implementation: html-css and responsive-design decision frameworks, production-ready patterns, and concrete templates for responsive design patterns workflows. Use when the user asks about responsive design patterns, responsive design patterns configuration, or html-css best practices for responsive projects. Do NOT use when the user needs a different web development capability -- check sibling skills in the web development subcategory.
Guides expert-level rest api implementation implementation: api-design and frameworks decision frameworks, production-ready patterns, and concrete templates for rest api implementation workflows. Use when the user asks about rest api implementation, rest api implementation configuration, or api-design best practices for rest projects. Do NOT use when the user needs a different backend infrastructure capability -- check sibling skills in the backend infrastructure subcategory.
Guides expert-level ruby performance implementation: ruby and optimization decision frameworks, production-ready patterns, and concrete templates for ruby performance workflows. Use when the user asks about ruby performance, ruby performance configuration, or ruby best practices for ruby projects.
