Gemini prompt for code generation: Feature Flag (With Examples)
Gemini · Code Generation · With Examples
You are a senior specialist using Gemini for code generation, specifically feature flag.
Job: safe rollout.
Audience: release. Constraint: default off.
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.Use this Gemini code generation template when release need feature flag with the rule: default off. 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 Google models, code generation prompts fail when they mix strategy and execution. This feature flag brief separates the job so you can iterate once, not ten times. Bookmark this page if you run feature flag weekly.
Why this prompt works
- Repeats the hard constraint: default off.
- Uses practical language that matches how practitioners actually brief work.
- Names a clear job so Gemini does not wander into generic advice.
- Separates draft from critique so you can steal the structure later.
- Locks the audience (release) before style so tone stays honest.
How to use it in Gemini
Redact client names; keep structure. Slug feature-flag-examples is your canonical URL for this brief. Paste the prompt into Gemini and replace bracketed details with your facts. Name the success metric aloud: safe rollout. If the draft cannot pass it, do not polish prose yet. When release review output, they should see few-shot samples and before/after pairs without hunting for it. Save the winning variant for feature flag — teams with a short library ship faster.
Swap the audience once. If the feature flag piece still works, the core is solid. For feature flag in code generation, the failure mode is usually vague audience. This prompt blocks that by design — especially "default off". Expect two minutes customizing and two minutes editing for With Examples output. Google models still need your facts for feature flag; they cannot invent metrics or brand rules. developers teams bookmark slug feature-flag-examples when few-shot samples and before/after pairs matters.
Step-by-step
- Open Gemini and paste the prompt block unchanged.
- Replace placeholders with your project facts (release, offer, timeline).
- Confirm the constraint is still visible: default off.
- 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 Feature Flag, 3 short sections, bullet list of recommendations, closing line that states default off. Facts you supply appear; nothing invented.
Common mistakes
- Skipping the audience (release) and hoping Gemini infers it.
- Using the With Examples prompt but editing it into a vague one-liner.
- Accepting the first draft without checking safe rollout.
Expert notes
