# Datafield descriptions Descriptions can be used to add explanations or comments to datafields. The user is free to include any description, comment or explanation in the description field so that the function of a description is completely up to the user (or the policy of the organisation). For example in more complex clauses or concepts with many datafields, descriptions could be used to explain the exact role a datafield plays in a certain clause, document or library. This will make it much easier for any future user editing the datafield to understand its use, thereby avoiding the situation where any changes are made to the datafield that e.g. ‘break’ a clause (for example by removing predefines). --- # 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://help.clause9.com/datafields/datafield-descriptions.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.
