Most people use AI. Almost no one uses it well.
Right now AI gives you inconsistent output. Sometimes brilliant. Often mediocre. You edit, retry, and wonder if it's worth the effort. In 12 weeks — practicing in Claude, coached by Finney — you build a prompt system that produces professional-quality output on demand. For any task. Every time.
Built for Claude. Coached by Finney.
Works in Claude Desktop, Claude Code, and claude.ai. Finney connects via MCP. Whichever Claude client you use every day — Finney's there.
Finney coaches you through every mission in Claude — he doesn't write the prompt, he asks the question that makes yours better. You learn to ask. That's the whole method.
What makes this different.
Finney — your coach in the hole
He's in Claude when you practice, and in your coaching area when you reflect. He remembers where you were last week — and he coaches by asking, never by handing you the answer.
60 hands-on missions
Every mission ends with a prompt or template you use at work. Not a quiz. Something real.
The five-part structure
Role. Context. Task. Format. Constraints. The skeleton of every good prompt you'll ever write. Most people skip four of the five.
Domain-specific in Week 6
Communicators, analysts, or builders — you pick the track that matches your work. The skills adapt to your vocabulary.
A deliverable, not notes
You don't collect notes here. Every mission adds to one real system you build and use at work — week over week, it compounds.
You can't fake it
Each checkpoint needs a prompt that actually ran — not a multiple-choice score. You can't reach the next stage without producing real work.
Your journey from guessing to mastery.

What you'll be able to do
Ship AI output without editing it
The output comes back right the first time. You go from rewriting what AI gives you to shipping it.
Control how the model reasons
Chain-of-Thought, few-shot, step-back. You know which technique to use when — and why it works.
Hand off a system that runs without you
By Week 12, a colleague can run your prompt system without asking what it means.
Carry your skills to any new tool
You don't learn one trick — you learn multiple prompt techniques that compound, and they transfer to every new AI tool you meet.
Prompt in your own domain's voice
Your prompts use your vocabulary, your context, your constraints. Not generic. Yours.
Fix bad output in one pass
When the answer is wrong, you know why — and you fix it in one iteration, not ten. Diagnosis, not trial and error.
Finish the journey. Walk away with your Proof of Work.
A certificate proves you showed up. Your Proof of Work proves what you can do — a set of real, usable deliverables, compiled automatically from the work you made along the way.
Case dossier
Your full project, written up — strategy, decisions, results. Word & PDF.
Pitch deck
A ready-to-present deck of what you built. PowerPoint & PDF.
Prompt playbook
Every prompt and template you made, packaged to reuse. Word & PDF.
Shareable portfolio
A public page of your work and its results — a link you can send.
Verifiable skill passport
A computed rating per skill, your rank, and an Open Badge anyone can verify.
Your Skill Twin
An installable AI coworker trained on your own work — it runs inside Claude and writes in your voice.
Built automatically from your real work the moment you finish — arriving for the first graduating cohort.
Why this skill matters.
The difference between AI users who get great output and those who don't is almost never the tool. It's what they ask for, and how. Prompt Mastery teaches that gap in 12 weeks.
The skill that makes every AI tool work better.
