Observation
The slowest part of EDA is often not the plotting or the SQL. It is defining what the pass is for, what counts as an anomaly, and what should be ignored.
What changed
Agents make the mechanical parts cheaper. They can summarize columns, flag nulls, cluster edge cases, and produce first-pass questions very quickly.
What did not change
They still need a human holding the frame. If the question is weak, the run gets wider instead of sharper.
Current rule
- Start with one operational question.
- Define one success condition before the run starts.
- Cut any branch that does not change a product or data decision.
