xAI Reasoning Agent

Combine ReasoningTools and YFinance on Grok 4.3 to write a stock report with visible reasoning.

Use ReasoningTools and YFinance with an explicit Grok 4.3 model to produce a TSLA report.

xAI now resolves the pinned grok-3-beta alias to grok-4.3, so its pricing and behavior follow Grok 4.3 rather than the original beta. Use the explicit current model ID before running. See Grok 4.3.
