AI agents call zeek_software_inventory to retrieve information from Zeek without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves software inventory data from Zeek logs. It performs passive analysis without side effects, state changes, or external actions. While the data returned could inform security decisions, the tool itself only reads and presents existing log information.
From the tool's definition Tool description states 'List detected software and versions' — a retrieval operation with no modification, deletion, or execution. The verb 'List' and context of parsing/querying network security monitoring data confirm read-only semantics.
