archive_library_item
AI agents call archive_library_item to permanently remove resources in Metis Public Health — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
Archiving a library item typically moves it out of active use in a way that may not be easily reversible, making it closer to Destructive than Write. However, the description is empty, so this is uncertain. Given the sibling tools context (PDF library management), archiving likely removes an item from the active index. Confidence is low due to lack of description.
