From Issue #7 of Cinz.AI — companion page for the Try It Tonight section.
You don't need the book. You don't need perfect notes. You just need to remember enough to get started, and let Claude do the rest.
Here's the three-step flow to build your own negotiation knowledge file, plus how to set up the Project so it actually coaches you.
Open a new chat (not your Project yet, just a regular chat) and say:
"I want to build a knowledge file based on Chris Voss's negotiation framework from Never Split the Difference. I'm going to share what I remember and what I found useful, and I want you to help me expand it into a structured reference I can save and reuse. Ask me questions one at a time to draw out what I know."
This works the same way for anything you've already learned. Attended a workshop? Say: "I took photos of the slides from a training on [topic]. Here's what I captured. Help me turn this into a knowledge file." Have rough notes from a recording? Same move. You give Claude the raw material, whatever form it's in, and it helps you shape it.
Once you've shared what you remember, ask:
"Based on what I've told you and what you already know about this framework, fill in anything important I might have missed. I want this to be complete enough that I can hand it to a future version of you and you'll know exactly how to apply it."
This is the part most people skip. Your AI was trained on a lot. It probably knows the framework you're working from. Let it contribute.
Once you're happy with the content, ask:
"Now format everything we've built as a clean markdown file I can save and upload to a Claude Project. Include a short section at the top explaining what the file is and how to use it, and a section at the bottom listing common use cases."
Download it, name it clearly, and it's ready to upload.
