WHAT IT DOES

What tag_and_search_library does on Aos

AI agents use tag_and_search_library to create or update resources in Aos, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Aos environment.

RISK

Why tag_and_search_library is rated Medium

The tool supports both reading (faceted browse/search) and writing (tag editing). Since tag editing modifies stored data, the most severe applicable category is Write. Blast radius is medium: misuse could corrupt or pollute library metadata, but changes are likely reversible.

From the tool's definition 'tag editing over a vault library' — the tool modifies tags on library entries (markdown notes in Recipes/ and Components/)
