development
Create distinctive, production-grade frontend interfaces with high design quality. Use this skill when the user asks to build web components, pages, or applications, OR when they provide screenshots/images/designs to replicate or draw inspiration from. For screenshot inputs, extracts design guidelines first using ai-multimodal analysis, then implements code following those guidelines. Generates creative, polished code that avoids generic AI aesthetics.
development
Use when the user asks to investigate, understand, explore, or explain how a feature works, asks about existing logic, or wants to understand code flow. Triggers on keywords like "how does", "explain", "investigate", "understand", "what does", "where is", "how works", "logic flow", "trace", "explore feature".
development
Use when the user asks to implement a new feature, enhancement, add functionality, build something new, or create new capabilities. Triggers on keywords like "implement", "add feature", "build", "create new", "develop", "enhancement".
development
Use when the user asks to generate comprehensive feature documentation with verified test cases, create feature README with code evidence, or document a complete feature with test verification. Triggers on keywords like "feature documentation", "document feature", "comprehensive docs", "feature README", "test verification", "verified documentation".
