List all collections (folders) in the library.
AI agents call list_collections to retrieve information from Zotero Assistant without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a query operation that retrieves and displays information about library collections without creating, modifying, deleting, or executing any operations. It is a non-destructive read operation with minimal security impact, appropriate for informational queries in a library management context.
