Claude prompt for code generation: Migration Script (With Examples)
Claude · Code Generation · With Examples
You are a systems thinker using Claude for code generation, specifically migration script.
Job: forward and back.
Audience: dba. Constraint: idempotent.
Working style: practical. Optimize for few-shot samples and before/after pairs.
Process:
1. Restate the brief in one sentence and list missing facts as questions.
2. Draft the artifact.
3. Stress-test it against the constraint.
4. Return a final version plus 3 numbered improvements.
Output contract: use headings, short paragraphs, and concrete examples. No filler. No invented statistics.
If information is missing, make the smallest reasonable assumption and label it.A Claude prompt for code generation is a copy-ready brief for migration script aimed at dba. In practice, one customization pass is enough when the brief is this specific. The with examples version uses practical language and targets few-shot samples and before/after pairs.
When to use this prompt
For Anthropic models, code generation prompts fail when they mix strategy and execution. This migration script brief separates the job so you can iterate once, not ten times. Swap only nouns when adapting — keep the process intact.
Why this prompt works
- Uses practical language that matches how practitioners actually brief work.
- Centers forward and back so success is observable.
- Names a clear job so Claude does not wander into generic advice.
- Repeats the hard constraint: idempotent.
- Forces an output contract: headings, examples, and a final version.
How to use it in Claude
Redact client names; keep structure. Slug migration-script-examples is your canonical URL for this brief. Use practical 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. This With Examples path is for dba who care about forward and back. If the first answer is vague, reply with the constraint again: idempotent.
Ask for a checklist dba would use. Then grade the draft against forward and back. For migration script in code generation, the failure mode is usually no example. This prompt blocks that by design — especially "idempotent". Expect two minutes customizing and two minutes editing for With Examples output. Anthropic models still need your facts for migration script; they cannot invent metrics or brand rules. developers teams bookmark slug migration-script-examples when few-shot samples and before/after pairs matters.
Step-by-step
- Open Claude and paste the prompt block unchanged.
- Replace placeholders with your project facts (dba, offer, timeline).
- Confirm the constraint is still visible: idempotent.
- Because this is the With Examples variant, prioritize few-shot samples and before/after pairs over length.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Migration Script, 3 short sections, bullet list of recommendations, closing line that states idempotent. Facts you supply appear; nothing invented.
Common mistakes
- Using the With Examples prompt but editing it into a vague one-liner.
- Ignoring the output contract headings.
- Accepting the first draft without checking forward and back.
Expert notes
Slug migration-script-examples: a developers-oriented code generation brief. Functions, refactors, tests, and architecture sketches. Pair it with one real asset from your portfolio before the second run.
Refresh quarterly: Claude models change. Keep constraints; update examples. Mark the page stale if idempotent no longer matches policy.
Comparison / variations
| Approach | When | Tweak |
|---|---|---|
| Bare request | You only need a spark | Write a migration script piece. |
| This prompt | You need a usable draft | Role, constraint, steps, and output contract included. |
| Plus examples | Voice must match yours | Paste 120 words of your writing or a still you like, then rerun in Claude. |
Key takeaways
- If text output drifts, re-anchor with idempotent.
- Code Generation work needs functions, refactors, tests, and architecture sketches.
- dba should recognize themselves in the first paragraph.
- Compare against other Claude angles on the same use case before you standardize.
- Document what changed when you customized slug migration-script-examples.
FAQ
- What is a Claude prompt for migration script?
- It is a structured brief that tells Claude how to produce code generation output for dba. This with examples version stresses few-shot samples and before/after pairs and keeps "idempotent" in the instructions.
- How do I customize this Claude code generation prompt?
- Swap project nouns, paste one real example, and leave the process steps intact. The constraint "idempotent" should stay unless your brief truly changed.
- Why use the with examples angle for migration script?
- Different angles solve different failures. With Examples helps when dba need few-shot samples and before/after pairs. It is not longer for its own sake — each line has a job.
- Is this Claude prompt updated for 2026?
- Yes. Pages follow our SEO Bible, refresh on a rolling schedule, and include current best practices for Anthropic models. Always verify facts before client delivery.
