Why web_extract is rated Low

The blast radius if misused by an AI agent is minimal—it can only access public web content that is already accessible. Classification as Read is appropriate.
From the tool's definition Tool name: 'web_extract'; description: 'Extract the readable content from any public URL and return it as clean markdown.' The verbs 'extract' and 'read' indicate data retrieval with no modification or deletion. Processing public URLs produces no side effects.
