# Reference

Use this section when you need precise lookup information rather than a guided workflow.

Reference pages are intentionally concise. Use them to confirm terminology, node families, built-in catalogs, settings, and execution semantics after you understand the basic authoring path.

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://flow-core.gitbook.io/flow-core-docs/documentation/reference.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
