# Type hints

Type hints is a hover feature that helps you identify the correct [node types](/learn/openapi/openapi-visual-reference/openapi-node-types) used in [configurable rules](/docs/cli/rules/configurable-rules#configurable-rules) and [custom plugins](/docs/cli/custom-plugins#custom-plugins) for writing rules or decorators.

When you hover over a node in your API description, a tooltip displays the node type, a short description, and a link to the corresponding documentation section.
