AI agents call check_dde_links to retrieve information from Oletools without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs static analysis by scanning Office documents for DDE (Dynamic Data Exchange) link artifacts. It retrieves and reports findings about document structure without creating, modifying, executing code, deleting data, or moving money. DDE link detection is a read-only inspection capability used for security auditing.
From the tool's definition Tool is named 'check_dde_links' and description states it 'Check[s] for DDE links using OLETools (msodde)'. The verb 'check' and 'detect' indicate inspection/analysis without modification.
