Data Whisperer

From vague business question to correct SQL, every time.

95 prompts4.8 average rating1,120 sold

Data Whisperer fixes the classic failure of AI-generated SQL: confident queries against misunderstood schemas. The pack's core ritual forces the model to interrogate your schema, confirm grain and join keys, and state its assumptions before writing a line of SQL.

Beyond generation, you get query-optimisation prompts that read EXPLAIN plans, dbt modelling guides that enforce naming and testing conventions, and metric-definition templates that end the 'why does your number differ from mine' meetings. Tested against Postgres, BigQuery and Snowflake.

What's inside

Sample prompts

A free taste of the pack — copy them, run them, judge us on the output.

Schema-first SQL generation

Here is my schema: [DDL OR TABLE LIST]. Business question: [QUESTION]. Do NOT write SQL yet. First: 1) restate the question as a precise metric definition including grain, filters and time window, 2) list the tables and join keys you'll use and any ambiguity you see, 3) ask me up to 3 clarifying questions. Only after my answers, write the SQL for Postgres.

Query optimisation review

Here is a slow query and its EXPLAIN ANALYZE output: [QUERY + PLAN]. Diagnose the top 3 bottlenecks in plain language, then provide a rewritten query for each bottleneck with the expected improvement and any index or table-change recommendations. Note anything that suggests the data model itself is the problem.

Built for

Correct SQL the first time

Schema-first prompts eliminate the confident-but-wrong joins that waste analyst afternoons.

Speed up slow queries

Paste a query and its EXPLAIN plan; get indexed, re-written versions with expected impact.

One source of truth

Metric templates lock definitions, owners and edge-case handling into your docs.
