Wireframe skill — Agents can ship one SVG per screen (desktop and mobile), a flow map, and an HTML viewer you can publish for review — before anyone commits to a build.
Improvements
Skill packaging for design reviews — Wireframe packages publish as a single reviewable artifact with navigation between screens.
Mobile + desktop pairs — Default templates encourage paired layouts so flows stay coherent across breakpoints.
Fixes
Broken SVG viewBox on nested symbols — Nested symbols keep a stable viewBox when exported from the wireframe skill.
Upgrade Guide
Install or update the wireframe skill from the Skills catalog, then ask an agent to draft screens before implementation.
