Gemini tends to drop constraints that appear early in the prompt, so boundary words like 'only', 'must', and 'strictly' placed at the end are essential. This free template is optimized specifically for Gemini, achieving approximately 37% token reduction compared to unoptimized prompts while producing higher quality output.
