WHY IT NEEDS A POLICY

Why upload_company_document needs a policy

Upload operations create or modify files reversibly, fitting the Write category. Severity is high because corporate documents are typically sensitive and a malicious upload could introduce malware, phishing content, or false records into company systems. Confidence is 0.85 (not higher) due to empty description—'upload' is clear from the name, but intent and scope are not explicitly documented.

From the tool's definition Tool name 'upload_company_document' indicates file creation/modification. Description is empty, limiting precision.
