What problem does it solve? When working with the jsgui3 UI framework, teams often face uncertain questions about event delegation, control activation, MVVM patterns, mixins, and helpers. This Skill provides a structured workflow to answer those questions empirically using the repo's lab experiments instead of guesswork, then preserves the validated findings as durable documentation. ## Core Features & Use Cases - Prior-art discovery: Searches existing docs and session records before running any experiment to avoid duplicate work. - Deterministic experiment execution: Runs targeted check scripts, delegation suites, and Puppeteer scenario suites to confirm jsgui3 behavior across SSR, client activation, and browser event semantics. - Minimal experiment authoring: Guides creation of new numbered experiments with hypothesis READMEs, assertion-based check scripts, and manifest registration when no existing coverage exists. - Knowledge distillation: Promotes validated results into Skills, Patterns, and subsystem guides so findings persist beyond a single session. - Use Case: A developer is unsure whether jsgui3 event delegation handles stopPropagation correctly during control activation. The Skill locates the relevant delegation scenarios, runs the shared browser runner, and records the confirmed behavior in the repo's pattern registry. ## Quick Start Ask the assistant to verify a specific jsgui3 behavior question by running the relevant lab experiment checks and recording the validated result in the repo documentation.
