AI agents call get_calls_extensive to retrieve information from Gong without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves call data from Gong's sales engagement platform. The 'get_' verb and context of sibling read-only tools confirm it performs data retrieval with no side effects. Severity is medium rather than low because call recordings and transcripts may contain sensitive business or customer information, and an agent could potentially retrieve and exfiltrate large volumes of confidential sales data.
From the tool's definition Tool name includes 'get_' prefix and description states 'Get extensive Gong calls', indicating data retrieval without modification. Sibling tools (get_call, get_call_transcripts, get_calls) are clearly Read operations, and this follows the same pattern.
