Gemini prompt for code generation: Security Review (Common Fixes)
Gemini · Code Generation · Common Fixes
You are a exacting editor using Gemini for code generation, specifically security review.
Job: threat notes on a snippet.
Audience: appsec. Constraint: owasp lens.
Working style: diagnostic. Optimize for typical failures and how to repair the prompt.
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 Gemini code generation template when appsec need security review with the rule: owasp lens. Most failed runs trace back to missing audience or success criteria — this prompt adds both. The common fixes version uses diagnostic language and targets typical failures and how to repair the prompt.
When to use this prompt
Gemini shines at code generation work when you state the observable outcome: threat notes on a snippet. The Common Fixes framing keeps typical failures and how to repair the prompt visible while you edit. Bookmark this page if you run security review weekly.
Why this prompt works
- Uses diagnostic language that matches how practitioners actually brief work.
- Keeps code generation vocabulary specific instead of buzzwords.
- Separates draft from critique so you can steal the structure later.
- Repeats the hard constraint: owasp lens.
- Centers threat notes on a snippet so success is observable.
How to use it in Gemini
Functions, refactors, tests, and architecture sketches. Keep that context in the thread when you iterate. Use diagnostic follow-ups only — mixing tones mid-thread confuses Google models. Redact client names; keep structure. Slug security-review-fixes is your canonical URL for this brief. Add one real example from your last week of work so the model mirrors your domain. For code generation work, paste gemini is useful for research synthesis, workspace-style tasks, and multimodal briefs as a one-line reminder above the prompt.
Swap the audience once. If the security review piece still works, the core is solid. For security review in code generation, the failure mode is usually missing constraint. This prompt blocks that by design — especially "owasp lens". Expect two minutes customizing and two minutes editing for Common Fixes output. Google models still need your facts for security review; they cannot invent metrics or brand rules. developers teams bookmark slug security-review-fixes when typical failures and how to repair the prompt matters.
Step-by-step
- Open Gemini and paste the prompt block unchanged.
- Replace placeholders with your project facts (appsec, offer, timeline).
- Confirm the constraint is still visible: owasp lens.
- If output is vague, ask Gemini to restate assumptions as questions first.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Security Review, 3 short sections, bullet list of recommendations, closing line that states owasp lens. Facts you supply appear; nothing invented.
Common mistakes
- Asking for security review plus three other jobs in one message.
- Using the Common Fixes prompt but editing it into a vague one-liner.
- Pasting confidential data instead of redacted placeholders.
Expert notes
Google users working on security review in code generation should treat "owasp lens" as non-negotiable. Functions, refactors, tests, and architecture sketches. When appsec run the Common Fixes variant, they usually care about typical failures and how to repair the prompt more than length.
If text output feels generic, re-paste owasp lens as the first follow-up message — do not rewrite the whole prompt.
