 The Agents sidebar `AICustomizationShortcutsWidget` supports three entrypoint modes via `sessions.customizations.sidebarMode`: `welcome` (default) keeps the per-category sidebar rows but opens the AI Customization management editor welcome page, `section` restores per-category deep linking, and `single` replaces the per-category rows with one Customizations entry that opens the welcome page. All modes keep the active customization harness in sync with the active session before opening the editor.
 
+When the harness selector dropdown is disabled in the management editor, the sidebar overview button displays the active harness name and harness icon (matching the picker icon) with a distinct background treatment.

 ### Item Badges
 
 `IAICustomizationListItem.badge` is an optional string that renders as a small inline tag next to the item name. For context instructions, this badge shows the raw `applyTo` pattern (e.g. a glob like `**/*.ts`), while the tooltip (`badgeTooltip`) explains the behavior. For skills with UI integrations, the badge reads "UI Integration" with a tooltip describing which UI surface invokes the skill. The badge text is also included in search filtering.
