+- [Rust](https://rustup.rs/) (for native CLI development)
+

+   ```
+
+5. Run tests:
+

+
+## Coding Style
+
+- **TypeScript**: All new code should be written in TypeScript with strict types.
+- **Formatting**: Code is formatted with [Prettier](https://prettier.io/). Run `pnpm format` before committing.
+- **Linting**: Run `pnpm lint` and fix any errors before opening a PR.
+- **Commit messages**: Use [Conventional Commits](https://www.conventionalcommits.org/) (e.g. `fix:`, `feat:`, `docs:`, `chore:`).
+- **Tests**: Add or update tests for any behavior you change. Tests live in the `test/` directory and use [Vitest](https://vitest.dev/).
+

+3. Push your branch and open a pull request against `dextonai/agent-browser:main`.
+
+4. Fill in the PR template and link any related issues (e.g. `Closes #123`).
