PromptMachine — AI skill for Claude Code

PromptMachine

**A library of prompts and skills that turn rough ideas into instructions an AI can actually execute.**

The first skill in the library is **Ultimate Prompt Engine**: plan mode on steroids. Give it an idea of any size, from one line to a page, and it interviews you like a senior engineer and a product designer would. It surfaces the decisions you have not thought about, asks them as plain questions with the stakes spelled out, never decides silently, and ends with a `spec/` folder a coding agent can build from without inventing anything.

What an interview looks like

From a real run on a bill-splitting app idea:

**Amit installs the app later and wants to claim the ghost "Amit" in your group. How does the app know it is really him?** If anyone can claim any ghost, someone could claim one to wipe a debt or read someone's history.

a) Personal claim link *(recommended)*: someone in the group sends Amit a link made only for that ghost, on WhatsApp b) Phone number match c) Pick from a list: easiest, but anyone can pick anyone d) Decide for me

Every question works this way:

• Plain words, with named people and concrete moments instead of jargon.
• The stakes are in the question, so you learn what the choice decides.
• Options are anchored to products you have used ("glassmorphism, like Apple's Control Centre").
• One recommendation, and always "Decide for me". Anything decided for you is logged with its reason and how hard it is to reverse.
• "Show me instead" for anything about looks: send screenshots and it extracts the palette and style.

What makes it different

Most spec prompts	Ultimate Prompt Engine
Ask generic questions ("What's your tech stack?")	Bans 9 generic questions by name and asks what you have not thought of
Decide quietly when you don't answer	Logs every assumption with reasoning, evidence and reversibility
Accept contradictions	Checks every answ
