Substring search over the episodic memory log (decisions + interventions) for prior discussions of a topic. Use to avoid re-deciding settled questions.
AI agents call did_we_discuss_this to retrieve information from Carto MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only searches and retrieves information from an episodic memory log to find prior discussions. It has no side effects, does not modify data, does not execute code, and does not affect external systems. The blast radius of misuse is minimal—returning irrelevant or incorrect historical context would only affect decision-making quality, not cause operational damage.
From the tool's definition "Substring search over the episodic memory log" - the tool retrieves and queries historical discussion data without modifying, deleting, or executing external operations.
