When to use this prompt
Picture a data eng professional opening Claude with one job: sql query. Without "explain plan notes", answers drift. This page prevents that drift. Swap only nouns when adapting — keep the process intact.
Why this prompt works
- Separates draft from critique so you can steal the structure later.
- Repeats the hard constraint: explain plan notes.
- Locks the audience (data eng) before style so tone stays honest.
- Centers correct join and filter so success is observable.
- Keeps code generation vocabulary specific instead of buzzwords.
How to use it in Claude
Name the success metric aloud: correct join and filter. If the draft cannot pass it, do not polish prose yet. Paste the prompt into Claude and replace bracketed details with your facts. Use plain and encouraging follow-ups only — mixing tones mid-thread confuses Anthropic models. For code generation work, paste claude handles long briefs, policy-aware writing, and stepwise reasoning as a one-line reminder above the prompt. Ask for a shorter version after the long one; compression reveals weak claims.
Run a constrained version and a wild version of sql query. Keep structure from one and energy from the other. For sql query in code generation, the failure mode is usually too many jobs in one ask. This prompt blocks that by design — especially "explain plan notes". Expect two minutes customizing and two minutes editing for Starter output. Anthropic models still need your facts for sql query; they cannot invent metrics or brand rules. developers teams bookmark slug sql-query-starter when first successful run with safe defaults matters.
Step-by-step
- Open Claude and paste the prompt block unchanged.
- Replace placeholders with your project facts (data eng, offer, timeline).
- Confirm the constraint is still visible: explain plan notes.
- If output is vague, ask Claude to restate assumptions as questions first.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with SQL Query, 3 short sections, bullet list of recommendations, closing line that states explain plan notes. Facts you supply appear; nothing invented.
Common mistakes
- Skipping the audience (data eng) and hoping Claude infers it.
- Accepting the first draft without checking correct join and filter.
- Ignoring the output contract headings.
