AI agents call search_disclosures to retrieve information from Dart without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and searches publicly disclosed financial documents from Korea's official DART system. It performs a read-only query operation with no side effects, data creation, modification, or deletion. The return of disclosure information constitutes data retrieval only. Low severity reflects minimal blast radius—searching public disclosures poses no direct risk even if an AI agent issues unexpected queries.
