Gemini prompts for developers
Curated Gemini prompts written for engineers, tech leads and indie hackers. Every prompt below is a copy-paste scaffold โ replace the brackets, run it in Gemini, and ship.
Why Gemini for developers
Coding prompts work best when they're scoped: one file, one feature, one decision. This pack treats the model as a senior pair โ give it the constraint, the code, and the format you want the answer in (diff, full file, list of suggestions). The prompts here cover the work engineers actually repeat: code review, targeted refactors, debugging from a stack trace, choosing between two architectures, and generating tests that hit real edge cases instead of trivial happy paths.
What you'll ship
Code reviews that catch real issues, not just style nits
Targeted refactors with before/after diffs
Debug from a stack trace + minimal reproduction
Generate unit tests that cover edge cases first
Starter Gemini prompts
Copy any prompt, replace the brackets, paste into Gemini. No account, no gate.
Targeted code review
You are a senior engineer doing a code review. The constraint: [CONSTRAINT โ e.g. must run on Cloudflare Workers]. Review this code:
[CODE]
Return: (1) bugs or runtime errors, (2) violations of the constraint, (3) up-to-3 refactors with a one-line rationale each, in priority order. Skip style nits.
