Show additional context and suggestions for error messages.
AI agents call enhance_error_message to retrieve information from QuantConnect MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool reads and presents error diagnostic information to help users understand failures. It has no side effects on data, system state, or financial positions. It does not execute code, modify strategies, run backtests, or affect live trading. The worst-case misuse would be providing misleading diagnostic suggestions, which carries only informational risk.
From the tool's definition Tool description states it 'Show[s] additional context and suggestions for error messages' — a retrieval and display operation with no data modification, deletion, or code execution. The verb 'show' indicates passive information retrieval.
