Build the Coach in your Claude.
Ghost Proof Coach lives in two places: ChatGPT and Claude. This page sets up the Claude version in your own workspace in five minutes. Same methodology. Same calibration. Same brand. Different platform.
Same Coach.
Wherever you work.
BUILD does not require a platform. The methodology travels. The Coach lives wherever you already trust your AI: ChatGPT, Claude, the next thing. We ship the same system to both because pretending one is the only place would be off-brand.
Claude Projects do not have a public marketplace yet, so the Claude version requires a five-minute setup in your own account. The ChatGPT version installs in one click via the GPT Store. Pick the platform you already use.
Three things you'll need.
Six steps.
In order.
Open Claude Projects
Go to claude.ai and sign in. In the left sidebar, click Projects. Then click Create Project in the top right.
Name it and describe it
Paste these into the Name and Description fields:
Paste the system prompt
Find the Custom Instructions field in the project. Open the System Prompt block below. Click Copy. Paste into the Custom Instructions field. Save.
The prompt is 6,007 characters. Voice-aligned with BUILD's brand system. v2 adds two behaviors: outcome capture on every return visit, and Ghost Ledger maintenance as a byproduct of working. Same prompt that runs the ChatGPT version.
Upload the three knowledge files
In the project's Project Knowledge section, click the + icon. Upload all three files from the Files section below: the OCI Method PDF, the knowledge base markdown, and the Ghost Ledger template.
The Coach reads the OCI Method and knowledge base to calibrate every message. The Ghost Ledger template tells the Coach how to build and maintain your Ledger across sessions.
Test with a real ghosted deal
Start a new conversation in the project. Try one of these:
The Coach should ask one question to identify the scenario, walk you through Observe, Connect, Invite, then emit your updated Ghost Ledger as a markdown code block at the end. Save the code block as your Ledger and attach it to your next session.
You are live
The project auto-saves. The Coach is now in your own Claude workspace. Use it on the next ghosted deal in your pipeline.
Two notes on the return visit. The Coach will open every future session by asking what happened on the open rows of your Ledger. Bring the latest Ledger file each time. You never type into it. The Coach maintains it.
If you want to share it with your team, Claude Projects supports workspace sharing on Team and Enterprise plans. For wider distribution, point your team to this page.
Paste this into Custom Instructions.
6,007 characters. Voice-clean. The OCI Method, the Coach flow, Ghost Ledger maintenance, return-visit outcome capture, the voice rules. All in one block. v2.
Three downloads.
Upload all three in Step 4.
These power the Coach. The OCI Method PDF and the knowledge base carry the methodology and the twenty-prompt library. The Ghost Ledger template carries the data contract the Coach maintains across your sessions.
The PDF is the same file we ship as the free OCI Method download at ghostproof.pro/method. The knowledge base markdown is the structured retrieval reference the Coach uses internally. The Ghost Ledger template is the schema. All three are public.
