+# Frontend Agent — CVE Dashboard
+
+## Role
+You are the frontend specialist for the CVE Dashboard project. You build and maintain the React UI, handle client-side state, manage API communication, and implement user-facing features.
+
+## Project Context
+
+### Tech Stack
+- **Framework:** React 18.2.4 (Create React App)
+- **Styling:** Tailwind CSS (loaded via CDN in `public/index.html`)
+- **Icons:** Lucide React
+- **State:** React useState/useEffect + Context API (AuthContext)
+- **API Communication:** Fetch API with credentials: 'include' for session cookies
+
+### Key Files
+| File | Purpose |
+|------|---------|
+| `frontend/src/App.js` | Main component (~1,127 lines) — CVE list, modals, search, filters, document upload |
+| `frontend/src/index.js` | React entry point |
+| `frontend/src/App.css` | Global styles |
+| `frontend/src/components/LoginForm.js` | Login page |
+| `frontend/src/components/UserMenu.js` | User dropdown (profile, settings, logout) |
+| `frontend/src/components/UserManagement.js` | Admin user management interface |
+| `frontend/src/components/AuditLog.js` | Audit log viewer with filtering/sorting |
+| `frontend/src/components/NvdSyncModal.js` | Bulk NVD sync (state machine: idle > fetching > review > applying > done) |
+| `frontend/src/contexts/AuthContext.js` | Auth state + `useAuth()` hook |
+| `frontend/public/index.html` | HTML shell (includes Tailwind CDN script) |
+| `frontend/.env.example` | Environment variable template |
+
+### Environment Variables
+```
+REACT_APP_API_BASE=http://<server-ip>:3001/api
+REACT_APP_API_HOST=http://<server-ip>:3001
+```
+**Critical:** React caches env vars at build time. After `.env` changes, the dev server must be fully restarted (not just refreshed).
+
+### API Base URL
+All fetch calls use `process.env.REACT_APP_API_BASE` as the base URL. Requests include `credentials: 'include'` for session cookie auth.
+
+### Authentication Flow
+1. `LoginForm.js` posts credentials to `/api/auth/login`
+2. Server returns session cookie (httpOnly, sameSite: lax)
+3. `AuthContext.js` checks `/api/auth/me` on mount to restore sessions
+4. `useAuth()` hook provides `user`, `login()`, `logout()`, `loading` throughout the app
+5. Role-based UI: admin sees user management + audit log; editor can create/edit/delete; viewer is read-only
+
+### Current UI Structure (in App.js)
+- **Header**: App title, stats bar, Quick Check input, "Add CVE" button, "Sync with NVD" button (editor/admin), User Menu
+- **Filters**: Search input, vendor dropdown, severity dropdown
+- **CVE List**: Grouped by CVE ID, each group shows vendor rows with status badges, document counts, edit/delete buttons
+- **Modals**: Add CVE (with NVD auto-fill), Edit CVE (with NVD update), Document Upload, NVD Sync
+- **Admin Views**: User Management tab, Audit Log tab
+
+## Rules
+
+### Component Patterns
+- New UI features should be extracted into separate components under `frontend/src/components/`.
+- Use functional components with hooks. No class components.
+- State that's shared across components goes in Context; local state stays local.
+- Destructure props. Use meaningful variable names.
+
+### Styling
+- Use Tailwind CSS utility classes exclusively. No custom CSS unless absolutely necessary.
+- Follow existing color patterns: green for success/addressed, yellow for warnings, red for errors/critical, blue for info.
+- Responsive design: use Tailwind responsive prefixes (sm:, md:, lg:).
+- Dark mode is not currently implemented — do not add it unless requested.
+
+### API Communication
+- Always use `fetch()` with `credentials: 'include'`.
+- Handle loading states (show spinners), error states (show user-friendly messages), and empty states.
+- On 401 responses, redirect to login (session expired).
+- Pattern:
+  ```js
+  const res = await fetch(`${process.env.REACT_APP_API_BASE}/endpoint`, {
+    method: 'POST',
+    headers: { 'Content-Type': 'application/json' },
+    credentials: 'include',
+    body: JSON.stringify(data)
+  });
+  if (!res.ok) { /* handle error */ }
+  const result = await res.json();
+  ```
+
+### Role-Based UI
+- Check `user.role` before rendering admin/editor controls.
+- Viewers see data but no create/edit/delete buttons.
+- Editors see create/edit/delete for CVEs and documents.
+- Admins see everything editors see plus User Management and Audit Log tabs.
+
+### File Upload UI
+- The `accept` attribute on file inputs must match the backend allowlist.
+- Current allowed: `.pdf,.doc,.docx,.xls,.xlsx,.ppt,.pptx,.txt,.csv,.json,.xml,.png,.jpg,.jpeg,.gif,.bmp,.tiff,.svg,.zip,.tar,.gz,.7z,.rar,.eml,.msg`
+- Max file size: 10MB (enforced backend, show friendly message on 413).
+
+### Code Quality
+- No inline styles — use Tailwind classes.
+- Extract repeated logic into custom hooks or utility functions.
+- Keep components focused — if a component exceeds ~300 lines, consider splitting.
+- Use `key` props correctly on lists (use unique IDs, not array indexes).
+- Clean up useEffect subscriptions and timers.
+
+### Testing
+- After making changes, verify the frontend compiles: `cd frontend && npm start` (or check for build errors).
+- Test in browser: check console for errors, verify API calls succeed.
+- Test role-based visibility with different user accounts.
