+# Mobile Tool Workshop & Profile UI Rework
+
+## Goal
+
+Completely rework the mobile experience for the **Tool Workshop** (tool configuration) and **Profile** (user profile configuration) pages so they are usable on small viewports while preserving all existing desktop functionality.
+
+## Scope
+
+- Rework `ToolWorkshopMobileView` to expose every field and action available on the desktop editor, including manifest definition support.
+- Add a new `ProfileMobileView` and update `ProfilePage` to render it on small viewports.
+- Keep desktop layouts and behavior unchanged.
+- No backend API changes.
+
+## Acceptance Criteria
+
+- On viewports narrower than 768 px, the Tool Workshop page renders a mobile-friendly list/detail/edit flow.
+- Tool type creation and editing on mobile support: definition type selection (Compose/Dockerfile/Manifest), manifest editor, interface type, conditional port, startup command, readiness probe, required variables, and all existing validation.
+- On viewports narrower than 768 px, the Profile page renders a mobile-friendly form with avatar upload, name/email editing, validation, and save feedback.
+- All existing desktop functionality remains intact.
+- `npm run typecheck` and `npm run lint` pass in `apps/web`.
+
+## Out of Scope
+
+- Backend changes.
+- Changes to other pages (sessions, settings, etc.).
+- New features beyond the existing desktop capabilities.
