Platform-specific advice to get the most out of every prompt.
Put durable rules (role, tone, output format, prohibitions) in the system instruction and keep per-message prompts short
Define the output format explicitly — AI Studio's structured output mode works best when your prompt names every field
Test your prompt against awkward, real-world inputs before shipping it, not just the happy path
Save prompt versions as you iterate so you can compare results across Gemini model updates
