Using AI in your Negotiations
In the section I give you the free tools based on Magnetic Influence that you can use to implement AI + human in every negotiation.
Instructions: Upload it into your own Claude under Settings/Customize → Skills. It works for users on Free, Pro, Max, Team, and Enterprise plans, as long as you have code execution enabled. It's easy - download the Zip file and go to Claude, then Settings > Customise > Skills > Create Skills > Upload a Skill (add the whole zip)
Next paste an email, describe a deal, or talk through an offer, and get the exact move and the words to use. Where Influence Meets Intelligence.
What it is
Most people use AI to write faster. This makes you negotiate better. The MAGNETIC Influence Coach turns Claude into a negotiation and influence coach trained on the framework from Tim Castle's book Magnetic Influence. Paste in a tricky email, describe a deal, or talk through an offer on the table — and get a clear read on where you stand and exactly what to do next. It's not theory. It's the move, the words, and the line to avoid.
What it does for you
Prep any negotiation before you walk in — know your position, your leverage, and your ask. Fix the email before you send it — paste a draft and get it rewritten to land, not leak. Pressure-test a big decision — two job offers, a pricing call, a partnership — and see what the numbers are really telling you. Build the conversation that wins the room — pitches, cold outreach, difficult feedback. Get the exact words to say — and the words that would quietly cost you.
How it works
Add it to Claude once — about two minutes, no technical skill required. Talk to Claude like you'd talk to a coach — describe the situation or paste the message. Get coached in real time — a clear score, your strengths and risks, your best next move, and the line to say.
Try saying "How can I generate more gravitas in this situation? Or I have a big salary negotiation coming up, here's the context, what should I do" Help me think it through." (paste the details) "How do I build gravitas before this board meeting?" Built on the MAGNETIC framework Eight principles behind every influential professional: Meaningful Impact, Authenticity, Gravitas, Generosity & Gratitude, Networking, Energetic Vibration, Trust, Intuition, and Connection. The Coach scores your situation across all eight and shows you where to sharpen.
The difference
This Coach builds influence, not tricks. No hard closes, no false urgency, no pressure tactics —those cost you trust and the next deal. It coaches you toward the kind of presence that makespeople want to work with you. You attract. You don't chase.
Who it's for
Leaders, founders, and sales teams. Anyone who sits across a table — or hits send on a message that matters. Get started Add the Coach to Claude — Free → Works with any Claude account (Free, Pro, Max, Team, or Enterprise). Two-minute setup.
