Claude prompt for code generation: Auth Middleware (Advanced)
Claude · Code Generation · Advanced
You are a pragmatic coach using Claude for code generation, specifically auth middleware.
Job: verify and reject.
Audience: security. Constraint: no secret leaks.
Working style: precise and demanding. Optimize for constraints, evaluation, and edge cases.
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.Use this Claude code generation template when security need auth middleware with the rule: no secret leaks. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The advanced version uses precise and demanding language and targets constraints, evaluation, and edge cases.
When to use this prompt
Picture a security professional opening Claude with one job: auth middleware. Without "no secret leaks", answers drift. This page prevents that drift. Bookmark this page if you run auth middleware weekly.
Why this prompt works
- Repeats the hard constraint: no secret leaks.
- Separates draft from critique so you can steal the structure later.
- Keeps code generation vocabulary specific instead of buzzwords.
- Asks for a self-check pass, which cuts hallucinated details.
- Names a clear job so Claude does not wander into generic advice.
How to use it in Claude
If the first answer is vague, reply with the constraint again: no secret leaks. Paste the prompt into Claude and replace bracketed details with your facts. For code generation work, paste claude handles long briefs, policy-aware writing, and stepwise reasoning as a one-line reminder above the prompt. Use precise and demanding follow-ups only — mixing tones mid-thread confuses Anthropic models. Redact client names; keep structure. Slug auth-middleware-advanced is your canonical URL for this brief.
Start with the ugly first pass for auth middleware. Name what is wrong in five bullets, then rerun in Claude. For auth middleware in code generation, the failure mode is usually vague audience. This prompt blocks that by design — especially "no secret leaks". Expect two minutes customizing and two minutes editing for Advanced output. Anthropic models still need your facts for auth middleware; they cannot invent metrics or brand rules. developers teams bookmark slug auth-middleware-advanced when constraints, evaluation, and edge cases matters.
Step-by-step
- Open Claude and paste the prompt block unchanged.
- Replace placeholders with your project facts (security, offer, timeline).
- Confirm the constraint is still visible: no secret leaks.
- For code generation work, paste a rubric and ask for a self-score.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Auth Middleware, 3 short sections, bullet list of recommendations, closing line that states no secret leaks. Facts you supply appear; nothing invented.
Common mistakes
- Using the Advanced prompt but editing it into a vague one-liner.
- Pasting confidential data instead of redacted placeholders.
- Asking for auth middleware plus three other jobs in one message.
Expert notes
Slug auth-middleware-advanced: 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 no secret leaks no longer matches policy.
Comparison / variations
| Approach | When | Tweak |
|---|---|---|
| Bare request | You only need a spark | Write a auth middleware 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
- Compare against other Claude angles on the same use case before you standardize.
- The Advanced variant is for constraints, evaluation, and edge cases.
- Keep no secret leaks visible in the prompt, not only in your head.
- If text output drifts, re-anchor with no secret leaks.
- Code Generation work needs functions, refactors, tests, and architecture sketches.
