# Percolating SQL-first The basic unit in Percolate is a transaction where we ask a question and get a response that could include a tool call and tool evaluation. We will look at this transaction first. After getting a feel for the atomic transactions, we can look into more complex sessions which can evolved a multitude of hops, queries and use of different tools and agents. ### The Transaction ### The Extended Dialogue --- # 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://percolation-labs.gitbook.io/percolation-labs/recipes/percolating-sql-first.md?ask= ``` 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.
