I need to identify time dimensions in this dataset and analyze them for spikes, dips, or breaks. From the evidence, I can see several temporal columns and gold tables with time-based aggregations. Let me first check what columns are available in one of the key temporal gold tables to understand the structure. {"action": "tool_call", "reasoning": "I can see from step-2 that there are gold tables with temporal aggregations. Let me inspect one of the most granular ones (hourly) to understand what metrics are available for trend analysis.", "tool": "inspect_columns", "args": {"table": "llm_calls_by_created_at__yyyy_mm_dd_hh_purpose"}}
