Install Produ­point

Four short steps: you copy, you paste, you're in. Every step says what you should see, and what to do if you don't.

1. 1Step 1: Check your Claude Code version

   In the Terminal, type this and press Enter:

   claude --version

   You should see a number like 2.1.241 (Claude Code). Anything 2.1.224 or higher is fine.

   • Lower than 2.1.224? Type claude update, press Enter, and check again (or update it however you installed it).
   • Check it here, in the Terminal. The Claude desktop app shows a different number (it looks like 1.4…) that says nothing about Claude Code.

   It says command not found? Then Claude Code isn't installed yet. Install it with Anthropic's own installer. Mac: paste this in the Terminal and press Enter:

   curl -fsSL https://claude.ai/install.sh | bash

   Windows (in PowerShell, where the line starts with PS): irm https://claude.ai/install.ps1 | iex. If it says 'irm' is not recognized, you are in Command Prompt: open PowerShell instead.

   When it finishes, close the Terminal and open a new one. (If the installer's last lines tell you to run a command, copy that line, paste it, and press Enter first.) Type claude, press Enter, and sign in with your Claude account in the browser window that opens. It needs a paid plan (see the card above). No browser window? The Terminal shows a sign-in link: copy it into your browser. Then type /exit and check the version again.

   Still command not found in a new window? Anthropic's install troubleshooting matches the exact message to a fix.

2. 2Step 2: Add your key

   On a Mac, this one line does it all. It finds your Claude Code settings file (it lives in a hidden folder, so you don't have to), keeps everything already in it, and adds Produpoint.

   It's long, and you don't need to read it. Click once inside the box to select all of it, copy it (⌘ + C), paste it into the Terminal (⌘ + V) and press Enter:

   (printf "Paste your key, then press Enter (it stays hidden): "; read -rs K; echo; K="$K" osascript -l JavaScript -e 'ObjC.import("Foundation");var e=$.NSProcessInfo.processInfo.environment,h=ObjC.unwrap(e.objectForKey("HOME")),k=(ObjC.unwrap(e.objectForKey("K"))||"").trim();if(!/^pp_live_[^\s<>"]+$/.test(k))throw "That does not look like a pp_live_ key. Nothing was changed.";var d=h+"/.claude",p=d+"/settings.json";if(!$.NSFileManager.defaultManager.createDirectoryAtPathWithIntermediateDirectoriesAttributesError(d,true,$(),null))throw "Could not save your settings file. Nothing was changed.";var s={},t=$.NSString.stringWithContentsOfFileEncodingError(p,4,null);if(!t.isNil()&&ObjC.unwrap(t).trim()){try{s=JSON.parse(ObjC.unwrap(t))}catch(x){throw "Your settings file has a mistake in it, so nothing was changed. Email us a screenshot of it, with your key hidden."}if(typeof s!=="object"||s===null||Array.isArray(s))throw "Your settings file is not in the expected shape, so nothing was changed.";if(!t.writeToFileAtomicallyEncodingError(p+".backup",true,4,null))throw "Could not save your settings file. Nothing was changed."}if(typeof s.extraKnownMarketplaces!=="object"||s.extraKnownMarketplaces===null)s.extraKnownMarketplaces={};s.extraKnownMarketplaces["yutom-plugins"]={source:{source:"url",url:"https://dl.produpoint.com/marketplace.json",headers:{Authorization:"Bearer "+k}}};if(!$(JSON.stringify(s,null,2)+"\n").writeToFileAtomicallyEncodingError(p,true,4,null))throw "Could not save your settings file. Nothing was changed.";"Done - Produpoint is set up. Now start Claude Code (step 3)."')

   It asks for your key. Paste it (⌘ + V) and press Enter. Nothing appears while you paste. That's normal: it keeps your key off the screen.

   You should see Done - Produpoint is set up. Now start Claude Code (step 3).

   • Paste it into the plain Terminal, not into Claude Code or the Claude app. If you see Claude Code's box, type /exit first. Never paste your key into a chat with Claude.
   • An error instead of Done? Find its words in If it does not work. Nothing was changed, so you can simply try again.
   • If your settings file already had things in it, a copy of how it was is saved beside it as settings.json.backup.
   On Windows

   1. In PowerShell (not Command Prompt), paste this and press Enter. Notepad opens your settings file:

      New-Item -ItemType Directory -Force "$HOME\.claude" | Out-Null; if (!(Test-Path "$HOME\.claude\settings.json")) { Set-Content "$HOME\.claude\settings.json" '{}' }; notepad "$HOME\.claude\settings.json"

   2. If the file is empty or holds only {}: select everything (Ctrl + A), delete it, and paste the block below. If it already has other things in it, see My file already has things in it.
   3. Replace <your-key> with your key, and delete the < and > too. Keep the quote marks around it.
   4. Save (Ctrl + S) and close Notepad. Then go to step 3.

   {
     "extraKnownMarketplaces": {
       "yutom-plugins": {
         "source": {
           "source": "url",
           "url": "https://dl.produpoint.com/marketplace.json",
           "headers": {
             "Authorization": "Bearer <your-key>"
           }
         }
       }
     }
   }

   On a Mac, but you'd rather edit the file yourself

   1. Paste this in the Terminal and press Enter. The file opens in TextEdit:

      mkdir -p ~/.claude && [ -f ~/.claude/settings.json ] || printf '{}\n' > ~/.claude/settings.json; open -e ~/.claude/settings.json

   2. If it holds only {}, replace it with the block shown under On Windows, then put your key in place of <your-key>.
   3. Paste, don't type, any quote marks. TextEdit can turn a typed quote into a curly one, which breaks the file.
   4. Save (⌘ + S) and close TextEdit.
   On Linux

   Your settings file is ~/.claude/settings.json (create the .claude folder and the file if they are missing). Open it in any text editor and follow steps 2 to 4 under On Windows, saving the file at the end.

   My file already has things in it

   On a Mac, just use the one line above: it keeps what is there. By hand, first copy the file somewhere safe, then add the extraKnownMarketplaces part alongside what is already there, and don't delete anything. If the file already has an extraKnownMarketplaces section, put the yutom-plugins entry inside that one instead of adding a second section. When a file has two sections with the same name, only one of them is used.

3. 3Step 3: Start Claude Code

   It has to start after step 2, so it picks up your key. In the Terminal, type this and press Enter:

   claude

   Was Claude Code already open? Type /exit first, then claude.

   It may ask a few questions first. Answer them: pick any colour theme, sign in with your Claude account if it asks, and when it asks "Is this a project you created or one you trust?", choose 1. Yes, I trust this folder. It picks up your key once it is past these questions. No questions at all? That's fine: you answered them earlier.

   You should see the Claude Code box, with a place to type.

   • Chose No by mistake? Claude Code closes. Type claude again and choose Yes.
   • Tip: start it in a folder for your idea, so your project has a home. Type mkdir -p ~/my-idea && cd ~/my-idea, press Enter, then type claude.

4. 4Step 4: Install Produpoint

   Inside Claude Code, type this and press Enter:

   /plugin install produpoint@yutom-plugins

   If a panel opens asking where to install it, choose the option for you (all your projects), not just this folder.

   You should see it install. To double-check, type /plugin and open the Installed tab: Produpoint is there.

   Seeing no such file or directory (Mac) or The term '/plugin' is not recognized (Windows)? You typed it in the plain Terminal or PowerShell. Type claude first, then this line.

   Type it exactly as shown. The part after the @ is the name of our catalogue, not of the plugin. Says Marketplace "yutom-plugins" not found? See the first row of If it does not work.

More, when you need it

curl -s -o /dev/null -w '%{http_code}\n' -H "Authorization: $(plutil -extract extraKnownMarketplaces.yutom-plugins.source.headers.Authorization raw ~/.claude/settings.json)" https://dl.produpoint.com/marketplace.json

Installing means you accept the terms.
