## 1. Install

```bash
npx rahman-resources add file-upload
# alias: npx rr add file-upload
```

The CLI copies `frontend/slices/file-upload/` into your project + augments `.env.example` + installs npm deps automatically. Run it from your project root.

## 2. What it ships

- shadcn primitives: `button`

## 3. Wire it up

Run `npx rr add file-upload`. Wrap your tree with `<FilesAdapterProvider adapter={...}>` — pass `useLocalStorageFilesAdapter()` for a quick demo or implement `FilesAdapter` (upload + remove + useUrl) against your backend. Then drop `<FileUploadButton onUploaded={...}>` anywhere; pair with `<FileChip fileRef={...}>` for rendered chips. Hooks: `useFileUpload()` returns `{upload, uploading, progress, removeFromStorage}`; `useFileUrl(storageId)` resolves to a fetchable URL (Convex adapter uses useQuery for live invalidation; demo reads localStorage synchronously). To wire S3: implement the FilesAdapter interface with presigned URLs + DELETE; the slice doesn't care which backend you pick.

## Rules of engagement

- shadcn-only UI primitives. No raw `<button>` / `<dialog>` / native date or file inputs.
- 200-line hard cap per source file (extract neighbours when over).
- All Convex queries hit an index (`.withIndex(...)`); never bare `.collect()`.
- Public mutations/queries declare `args:` validators + authz.

The agent will fetch /llms.txt for the full ruleset and use /api/knowledge for the JSON catalog.
