LLM Data Profiling Report Prompt

Table schema and sample rows: {{sample}}

Produce a profile: row count and grain, each column's type and null rate, columns that look like they should be unique but aren't, columns with suspicious value distributions (e.g. one value dominating), and likely foreign keys to other tables.
Flag anything that would break a naive average or count if not handled.

Replace the {{fields}} with your own context and tighten the rules to match your domain.
