+# Vibe Dashboard
+
+React 19 + TypeScript + Vite 7 dashboard. pnpm monorepo.
+
+## Commands
+```bash
+pnpm install   # Install deps (~10s, timeout 60s+)
+pnpm dev       # Dev server at localhost:5173
+pnpm build     # Production build (~7s)
+pnpm lint      # Run ESLint
+pnpm fmt       # Format with dprint
+```
+
+## Structure
+- `apps/dashboard/src/App.tsx` - Main dashboard with metrics
+- `apps/dashboard/src/App.css` - Styles
+- Root `package.json` - Workspace scripts
+
+## Adding Metrics
+Edit `App.tsx`: Add data array + metric object with id/name/icon/data/color.
+
+## Search
+You run in an environment where `ast-grep` is available; whenever a search requires syntax-aware or structural matching, default to `ast-grep --lang rust -p '<pattern>'` (or set `--lang` appropriately) and avoid falling back to text-only tools like `rg` or `grep` unless I explicitly request a plain-text search.
+
+## Always
+- Run `pnpm lint && pnpm build` before commits
+- Prefer editing existing files over creating new ones
+- Don't create docs unless explicitly requested
