Query the substrate
AI agents call myco_query_forged_understanding to retrieve information from Myco — Agent-First Cognitive Substrate without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves or inspects state from a cognitive graph substrate. The verb 'query' combined with 'Query the substrate' clearly indicates a read-only operation that retrieves information. There is no indication of side effects, modifications, code execution, or deletion. The unusual name 'forged_understanding' does not override the functional semantics of a query operation.
From the tool's definition Tool name contains 'query' and description states 'Query the substrate' — both indicate data retrieval without modification.
