This skill helps developers design system architecture by analyzing constraints and trade-offs, then documenting decisions using ADR-lite. It focuses on component boundaries, dependencies, data flow, and operational requirements like observability and scalability. Use it when you have architectural requirements in `doc/input/rdd.md` or need guidance on design decisions and non-functional requirements.

This Claude Skill helps developers implement features using minimal, precise TDD cycles (RED→GREEN→REFACTOR) and diff-based thinking. It focuses on preventing design degradation like unclear responsibilities or temporary fixes, ensuring changes are review-ready. Use it for implementation, refactoring, bug fixes, or quality improvements to maintain both speed and code quality.

The biz-researcher skill structures market and competitive analysis to support business decisions by organizing evidence, uncertainties, and next steps. It prioritizes verified sources and avoids speculation, explicitly separating facts from hypotheses. Use it when you need to validate a business hypothesis, assess market risks, or require well-sourced data for strategic planning.

The creative-coder skill helps developers translate UI animation and interaction design goals into implementable constraints without sacrificing accessibility or performance. It provides a structured framework for designing state transitions and timing, prioritizing reduced-motion support and core web vitals. Use this skill for consultations on implementing expressive UI animations, micro-interactions, and scroll/transition effects.
