From a conversation to a graph, in one command.

Set up the Unified Product Graph (UPG) on my machine so I can use it with my AI assistant. First read the official setup docs at https://unifiedproductgraph.org/mcp, then walk me through the steps and run them for me.

1. Check my environment: tell me my operating system, and confirm Node.js 18+ and npm are installed. If either is missing, give me the install link for my OS and stop here.
   (Windows: if PowerShell blocks npm or npx with an execution-policy error, use the npm.cmd / npx.cmd wrappers, or run the commands in Command Prompt.)
2. Install the UPG CLI globally:  npm install -g @unified-product-graph/cli
3. Create my product graph in this folder:  upg init --title "My Product" --template blank --yes  (the --yes flag is required so it does not stop on an interactive menu; templates: blank, saas, marketplace, mobile, oss; add --force to overwrite)
4. Wire up the MCP server so my AI tool can read and write the graph:  upg mcp setup  (add --scope user to make it available in every project). That writes the standard .mcp.json entry; the server runs on demand via npx, so there is nothing else to install.
5. Install the /upg-* slash commands:  upg install-skills  (add --scope user for every project)
6. Verify the install:  upg health  and  upg mcp status  (the server should show as connected).

When you are done, tell me where each file was written and how to run my first /upg command. If you hit a permissions error, tell me exactly what access you need.
