How to Use Claude as a Business Consultant: The Thomas Skill Guide

Hiring a consultant is expensive; the thinking a good one provides is what you are actually paying for — structure, hard questions, and options you had not considered. When people use Claude as a business consultant with a loose prompt, they get agreeable advice that flatters the plan they already had. A real AI business consultant does the opposite: it challenges the brief before it answers it.

Thomas is that consultant. He is a strategy persona you load once into Claude, ChatGPT, or any AI chat, and he is built to resist the easy “yes”. Give him a decision and he first makes sure it is the right decision to be making, then structures the problem so the answer is reasoned rather than reassuring.

Why generic AI business advice falls flat

Unguided, a chatbot agrees with you. It reflects your framing back, reaches for a generic framework whether or not it fits, and offers one tidy recommendation with none of the trade-offs that make a decision real. Advice that never makes you uncomfortable is rarely advice worth having — and that is exactly what a bare prompt tends to produce.

What changes with the Thomas skill

Thomas structures the problem before solving it, separating the decision you think you face from the one you actually do. He asks the uncomfortable questions a good consultant asks, applies real frameworks to your specific situation rather than reciting them, and lays out options with their trade-offs instead of a single answer. You leave with a clearer problem and a set of choices you can defend.

What it actually produces

Problem framing that names the real question, an options analysis with trade-offs, strategy frameworks applied to your case, risk breakdowns, and decision memos you could put in front of a co-founder or board. Ask him to play devil’s advocate on a plan and he will — with reasons, not contrarianism.

How to get the most out of it

Give him the real situation, constraints and all, rather than a sanitised version. Ask him explicitly to challenge your thinking rather than confirm it — the pushback is the product. And ask for options with trade-offs instead of a single recommendation, so the decision stays yours and stays informed.

Who this is for

Founders weighing a major decision, owners and operators without a board to test ideas against, and managers who need to think a problem through properly before they commit. It works with Claude, ChatGPT, or any AI chat that accepts a system prompt. For the execution that follows, the work & business skills collection covers planning, operations, and analysis — each a focused assistant rather than a general chatbot.
