AI agents call faction_wizard to retrieve information from Narrarium without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool only returns a checklist/template to guide the agent in gathering information. It does not create, modify, or delete any data — the actual faction file creation would be a separate step. This is purely a read/retrieval operation.
From the tool's definition Return the Narrarium faction creation checklist so the agent can gather the right details before creating a faction file.
