WHAT IT DOES

What attachments_fetch does on OpenClaw

AI agents call attachments_fetch to retrieve information from OpenClaw without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why attachments_fetch is rated Low

This tool retrieves and lists attachment metadata from a conversation message. It performs a read-only query operation without creating, modifying, deleting, or executing any code. The blast radius of misuse is minimal—an agent could only access existing attachment information, not alter it or trigger external actions.

From the tool's definition Tool name 'attachments_fetch' and description 'List non-text attachments for a message' indicate retrieval/listing operation with no modification or side effects.
