## 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

- npm: `lucide-react`
- shadcn primitives: `button`

## 3. Wire it up

Default React/Next: run `npx rr add file-upload`, wrap with `<FilesAdapterProvider adapter={...}>`, then use `<FileUploadButton>` / `<FileChip>` and the React hooks. Svelte/SvelteKit: run `npx rr add file-upload --framework sveltekit`, wrap with the Svelte `<FilesAdapterProvider>`, and implement `FilesAdapter` with upload + remove + resolveUrl plus optional subscribeUrl for live invalidation. The bundled localStorage adapter is demo-only; production hosts can target Convex/S3/GCS/R2. The dangerous `files.remove` tool remains server-checked and requires confirmation.

## 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.
