+# Task 047 - Tabs Tailwind Refactor
+
+## Goal
+Refactor instance and session tab components to rely on Tailwind utilities and shared tokens, aligning with the design spec for spacing, typography, and state indicators.
+
+## Prerequisites
+- Task 046 complete (prompt input refactor) to keep merges manageable.
+
+## Acceptance Criteria
+- [ ] `src/components/instance-tabs.tsx` and `src/components/session-tabs.tsx` no longer reference legacy `.instance-tabs`, `.session-tabs`, `.session-tab` classes from `src/index.css`.
+- [ ] Global CSS for tab bars (`.connection-status`, `.status-indicator`, `.status-dot`, `.session-view`) is replaced or minimized in favor of Tailwind utilities and token variables.
+- [ ] Active, hover, and error states match the UI spec in both themes, including badges/icons.
+- [ ] Tab bar layout remains responsive with overflow scrolling where applicable.
+
+## Steps
+1. Catalogue existing tab-related classes used in both components and in `src/index.css`.
+2. Convert markup to Tailwind class lists, leveraging tokens for colors/borders (e.g., `bg-[var(--surface-secondary)]`).
+3. Add any reusable tab utilities to `src/styles/components.css` if needed.
+4. Remove obsolete CSS blocks from `src/index.css` once coverage is confirmed.
+5. Smoke-test tab interactions: switching, closing (where allowed), error state display, and overflow behavior.
+
+## Testing Checklist
+- [ ] Run `npm run build`.
+- [ ] In dev mode, load multiple instances/sessions to verify active styling and horizontal scrolling.
+
+## Dependencies
+- Depends on Task 046 completion.
+- Blocks subsequent polish tasks for tab-level layout.
+
+## Estimated Time
+1.0 hour
+
+## Notes
+- Branch suggestion: `feature/task-047-tabs-tailwind-refactor`.
+- Provide before/after screenshots (light/dark) of both tab bars in the PR for clarity.
