Confirm the funnel stages, entity identifier, time field, and analysis period. Ask one concise question if a critical definition is missing.
Inspect the schema before querying. Never invent stage names or event definitions.
Calculate the entity count at each stage, step conversion rate, cumulative conversion rate, and loss from the preceding stage.
Segment the largest loss by relevant dimensions such as channel, region, product, or customer cohort when the data supports it.
Separate observed facts from hypotheses. Quantify every important claim and cite the source table or analysis result.
End with the top three prioritized actions, their expected mechanism, and the metric that should be monitored.

Prefer a funnel chart or a compact stage-by-stage table. If stage ordering is ambiguous, do not guess—ask the user.
