Everything you need in one collection
Code Review & Refactor Kit for SaaS. A ready-to-run set of prompts tailored to a B2B SaaS product: copy a prompt, replace the bracketed details, and paste it into ChatGPT, Claude, or Gemini.
Overview
A tight, 6-prompt toolkit — the Code Review & Refactor Kit for SaaS is built for SaaS teams. You'll get prompts such as “Refactor for clarity”, “Write tests” and “Explain this code”. The structure is already done, so instead of engineering a prompt you just fill in what makes your situation unique. Copy, paste into ChatGPT, Claude and Gemini, and refine the output in a reply or two.
