10 prompts every plumber should have saved on their phone. A few of them: 1. Photo of a fitting/cartridge you don't recognize → manufacturer + model + 3 sources. 2. IPC section in code-book English → plain English for the inspector or the homeowner. 3. Paste your scope → permit narrative the township will accept on first read. 7. Email claiming a "permit fee" is owed → 3 tells + what to do before paying anything. All 10 work in free Claude / ChatGPT / Gemini. No subscription. No software.
