AI agents call timeline_event_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's purpose is to return a checklist to guide the agent in gathering details before creation. It is a read/fetch operation with no side effects. The actual creation of a timeline event file would be a separate step. Low severity as it only surfaces a static or pre-defined checklist.
From the tool's definition "Return the Narrarium timeline event checklist" — retrieves/returns a checklist template; no data is created or modified
