What trend_init does on Geoseo

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

WHY IT NEEDS A POLICY

Why trend_init needs a policy

This tool creates a new SQLite database file. Creation is a reversible Write operation—the database can be deleted or recreated. It does not execute arbitrary code, delete data, move money, or trigger irreversible side effects.

From the tool's definition Tool description states "Create the local SQLite snapshot DB if it doesn't exist; return its path." The verb 'Create' indicates data modification.
