## Medusa Rules

## General Rules

- Don't use type aliases when importing files.
- When throwing errors, always throw `MedusaError`.
- Always use Query to retrieve data.

## Workflow Rules

- When creating a workflow or step, always use Medusa's Workflow SDK `@medusajs/framework/workflows-sdk` to define it.
- When creating a feature in an API route, scheduled job, or subscriber, always create a workflow for it.
- When creating a workflow, always create a step for it.
- In workflows, use `transform` for any data transformation.
- In workflows, use `when` to define conditions.
- Don't use `await` when calling steps.
- In workflows, don't make the workflow function async.
- Don't add typing to compensation function's input.
- Only use steps in a workflow.

## Data Model Rules

- Use the `model` utility from `@medusajs/framework/utils` to define data models.
- Data model variables should be camelCase. Data model names as passed to `model.define` should be snake case.
- When adding an `id` field to a data model, always make it a primary key with `.primaryKey()`.
- A data model can have one `id` only, other IDs should be `text` instead.
- Data model fields should be snake case.

## Service Rules

- When creating a service, always make methods async.
- If a module has data models, make the service extend `MedusaService`.

## Admin Customization Rules

- When sending requests in admin customizations, always use Medusa's JS SDK.
- Use TailwindCSS for styling.
