AI agents call strings_list_glossaries to retrieve information from Phrase without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and enumerates existing glossaries/term bases from a Phrase Strings account. It performs a query operation without creating, modifying, deleting, or executing any actions. The blast radius of misuse is minimal—an AI agent could only enumerate glossaries, not alter them or access sensitive data beyond what the API credentials permit.
From the tool's definition Tool name contains 'list' and description states 'List term bases (previously: glossaries)' - a pure retrieval operation with no modification or side effects.
