# What does the GitHub App check?

> The GitHub App is planned; it checks four things on every pull request: lint, golden tests on DuckDB, a cost estimate and a preview dashboard link.

The GitHub App is planned; nothing can be installed yet. It checks four things on every pull request.

- **Lint:** your SQL and Python checked against your platform's rules, so known traps are caught before anything runs.
- **Golden tests:** the templates' tests run on DuckDB with the fixtures committed in your repository.
- **Cost:** an estimate of what the change costs to run on your target platform.
- **Preview:** a link to a dashboard built from the change, so reviewers can see the result.

The app asks only for read access to contents and metadata, and write access to checks and pull requests. Read about the [GitHub integration](https://emolysis.com/integrations/github) and the [GitHub checks docs](https://emolysis.com/docs/github-checks), or [run the checks in your own CI](https://emolysis.com/faq/run-checks-in-my-own-ci).
