AI agents call get_citation_network to retrieve information from Legal without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries existing legal citation metadata without creating, modifying, deleting, or executing operations. It is a straightforward data retrieval function consistent with the server's stated purpose of enabling legal research through the CourtListener API. The blast radius of misuse is minimal—returning irrelevant or excessive citation data causes no operational harm.
