WHY IT NEEDS A POLICY

Why deal_fact_add needs a policy

This tool creates new data records (factual claims) about deals on the Llama Ventures platform. It is reversible (facts can be edited or deleted via sibling tools like brief_edit or brief_delete), making it Write rather than Destructive.

From the tool's definition Tool name 'deal_fact_add' and description 'Record a factual claim about a deal' indicate creation/modification of data. The RESPONSIBILITY annotation 'set' further confirms a write operation that sets or creates a new fact record.
