pattern-implement

Quick Review

The skill provides solid technical guidance for implementing sub-patterns with clear examples of action(), handler(), and rendering patterns. However, the Description ('Build sub-patterns with minimal UI') is quite vague for CLI invocation—it doesn't specify what triggers this skill or what inputs are needed. The task knowledge is strong with concrete code examples and references to external docs. Structure is good and concise. Novelty is moderate: while pattern implementation has specific framework conventions (action/handler/Cell), a capable CLI agent could potentially accomplish this with sufficient context, though the skill does consolidate framework-specific idioms efficiently.
