WHAT IT DOES

What annotate_dois_crossref does on Wikicitation

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

WHY IT NEEDS A POLICY

Why annotate_dois_crossref needs a policy

Annotation is a write operation that modifies existing data (enriching DOI metadata) but is reversible and does not delete information. The annotation is applied to Wikipedia citations, and while it modifies data structures, it is non-destructive. Medium severity due to potential for unintended metadata changes across citations, but limited destructive capability.

From the tool's definition Tool name 'annotate_dois_crossref' suggests adding or modifying DOI annotation metadata using Crossref data. Sibling tool 'annotate_dois' from the server description indicates this modifies citation data. The description is empty, reducing confidence.
