You are a hands-on practitioner using Gemini for code generation, specifically cache strategy.
Job: keys and ttl.
Audience: perf. Constraint: invalidation.
Working style: current and tactical. Optimize for what works now, including evaluation loops.
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.This Gemini code generation cache strategy prompt helps you keys and ttl without rewriting instructions from scratch each time. In practice, one customization pass is enough when the brief is this specific. The 2026 playbook version uses current and tactical language and targets what works now, including evaluation loops.
When to use this prompt
Picture a perf professional opening Gemini with one job: cache strategy. Without "invalidation", answers drift. This page prevents that drift. Bookmark this page if you run cache strategy weekly.
Why this prompt works
- Forces an output contract: headings, examples, and a final version.
- Uses current and tactical language that matches how practitioners actually brief work.
- Keeps code generation vocabulary specific instead of buzzwords.
- Names a clear job so Gemini does not wander into generic advice.
- Repeats the hard constraint: invalidation.
How to use it in Gemini
When perf review output, they should see what works now, including evaluation loops without hunting for it. Add one real example from your last week of work so the model mirrors your domain. If the first answer is vague, reply with the constraint again: invalidation. Functions, refactors, tests, and architecture sketches. Keep that context in the thread when you iterate. Redact client names; keep structure. Slug cache-strategy-playbook is your canonical URL for this brief.
Have Gemini list assumptions about code generation before drafting. Delete any you cannot defend. For cache strategy in code generation, the failure mode is usually missing constraint. This prompt blocks that by design — especially "invalidation". Expect two minutes customizing and two minutes editing for 2026 Playbook output. Google models still need your facts for cache strategy; they cannot invent metrics or brand rules. developers teams bookmark slug cache-strategy-playbook when what works now, including evaluation loops matters.
Step-by-step
- Open Gemini and paste the prompt block unchanged.
- Replace placeholders with your project facts (perf, offer, timeline).
- Confirm the constraint is still visible: invalidation.
- Because this is the 2026 Playbook variant, prioritize what works now, including evaluation loops over length.
- Reply with one fix list, then regenerate the final version only.
Example output
Example output shape: H1 with Cache Strategy, 3 short sections, bullet list of recommendations, closing line that states invalidation. Facts you supply appear; nothing invented.
Common mistakes
- Using the 2026 Playbook prompt but editing it into a vague one-liner.
- Asking for cache strategy plus three other jobs in one message.
- Skipping the audience (perf) and hoping Gemini infers it.
