What problem does it solve? Designing and validating Web mock UI screens for TritonKit requires consistent rules about ports, component libraries, device canvas behavior, and evidence panels, and this Skill encodes those rules so prototypes stay aligned with the CLI/HTTP business-control contract. ## Core Features & Use Cases - React/Vite Mock Implementation: Guides creation of React + TypeScript + Vite mock apps in Web/ with Ant Design components, fixed dev/preview ports, and mock DTO data modules. - Device Canvas & Hierarchy Patterns: Defines interaction rules for screenshot mirroring, tap/type/paste input relays, Lookin-style hierarchy viewers, and network/log evidence panes. - Validation Workflow: Enforces build checks, browser smoke tests at 127.0.0.1:34127, and documentation updates before delivery. - Use Case: When asked to prototype a TritonKit dashboard showing an iOS simulator mirror with a hierarchy inspector, this Skill ensures the screen uses DTO-shaped data, honest fallback labels, and read-only Web boundaries. ## Quick Start Ask the agent to create a TritonKit Web mock UI screen for a device mirror with target list and evidence panels using this skill.
