WHY IT NEEDS A POLICY

Why pinterest_ingest needs a policy

This tool writes/stores data (visual analyses) into a ChromaDB vector database. It creates new records in a persistent data store, which is a reversible write operation. It does not delete data, execute code, or involve financial transactions. Severity is medium because it modifies a shared vector database that could be polluted with bad data by a misusing agent, affecting downstream semantic retrieval quality.
