Best Gemini Prompt for “Write a Technical Spec”
Gemini uses a sandwich structure: role and context at the top, task in the middle, and all constraints at the end. 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.

Why This Gemini Prompt for “Write a Technical Spec” Works Better
When you type “Write a technical specification for [feature]” into Gemini, it lacks structure — Gemini has to guess what format you want, how detailed to go, and what to prioritize. The optimized version removes that guesswork.
It uses a sandwich structure with role and context at the top, the task in the middle, and all hard constraints at the end — matching how Gemini processes and prioritizes instructions.
