Explain a complex SQL query in plain English

Use to understand or review an inherited query you did not write.

The prompt
prompt.txt
Act as a SQL reviewer who explains queries clearly.

Query ({{sql_dialect}}):
{{query}}

Task:
1. Summarize in one sentence what this query returns.
2. Walk through it step by step, CTE by CTE or clause by clause, in reading order, explaining what each part does and why.
3. State the grain of the result set (one row per what).
4. List any assumptions, edge cases, or bugs you notice (silent joins fanning out, missing filters, NULL handling, timezone issues).
5. Suggest one improvement to readability or correctness.

Use plain language a junior analyst would understand.
