## Develop

From the **repo root**:

```bash
npm run chrome:install
npm run chrome:dev      # hot reload
npm run chrome:build    # → packages/chrome/.output/chrome-mv3/
npm run chrome:zip      # store package
npm run chrome:test
npm run chrome:typecheck
```

Or inside this package:

```bash
npm install
npm run dev
npm run build
```

### Load unpacked

1. `npm run chrome:build`
2. Chrome → `chrome://extensions` → Developer Mode
3. **Load unpacked** → select `packages/chrome/.output/chrome-mv3`

## Shared core

Provider adapters and prompts live in [`../../src/lib`](../../src/lib) (`@lib/*`). Do not import `@lib/crypto` or `@lib/messaging` from the VS Code or CLI packages.

## Version

Bump `version` in this package’s `package.json` only — the extension manifest follows it via `wxt.config.ts`.
