Download your Arlo OS folder
This is the starter kit that connects Claude to Blaney Group. It includes the company instructions and a template you'll fill in about your role.
Download Arlo OS Starter Kit- Click the button above to download arlo-os.zip
- Find it in your Downloads folder
- Double-click to unzip it — you'll get a folder called "Arlo OS"
- Move that folder somewhere you'll remember — Desktop or Documents works fine
Open Cowork and select your folder
Cowork is the mode in Claude that lets it read and save files on your computer. This is what makes it remember things between sessions.
- Open the Claude desktop app
- Look for the "Cowork" option in the sidebar or home screen and click it
- You'll be asked to select a folder — choose the "Arlo OS" folder you just unzipped
- Claude will confirm the folder is connected
Paste this prompt to start
Copy the prompt below and paste it into your Cowork chat. Claude will read your company files, run a short interactive tutorial, and get ready to work with you.
Hi! I'm setting up Arlo OS for the first time. Please read CLAUDE-INSTRUCTIONS.md from my folder and follow it.
Not sure your folder is connected? Type this quick message first and check what Claude says:
List the files in my Cowork folder.
Claude lists files including CLAUDE-INSTRUCTIONS.md and an _system folder. You're connected — paste the setup prompt.
Claude says it doesn't have folder access or sees no files. Go back to Step 3 and re-select your folder in Cowork.
✅ That's it — you're set up
Once you've done these five steps, Claude knows who you are, how Blaney Group works, and can control your browser. Every session from here will pick up where the last one left off. Head to the Tutorial to learn what to do next.
Troubleshooting
Something not working? Find your situation below.
This almost always means the folder isn't connected. Fix it in three steps:
- Go back to the Claude app home screen
- Click Cowork (or the briefcase icon)
- When it asks to select a folder, choose your Arlo OS folder — the one you unzipped in Step 2
Then try the connection check again: List the files in my Cowork folder.
You've selected the wrong folder. Claude is reading a different folder on your computer. To fix:
- In Claude, look for the folder selector (usually shown near the top of the Cowork panel)
- Click it and re-select the correct Arlo OS folder
- The folder should contain
CLAUDE-INSTRUCTIONS.mdat the top level, not inside another folder
Common mistake: selecting the parent folder instead of the Arlo OS folder itself. Make sure you go inside the unzipped folder before hitting Select.
Check your Downloads folder — that's where it goes by default.
- Mac: Double-click the .zip file to extract it. You'll see a new folder appear called "Arlo OS" right next to the zip.
- Windows: Right-click the .zip and choose Extract All, then choose where to put it.
After extracting, move the Arlo OS folder somewhere easy to find — Desktop or Documents. Then go back to Step 3.
This usually means the folder wasn't connected when you sent the prompt. Claude needs the files to be accessible to read them.
- Run the connection check:
List the files in my Cowork folder. - If Claude doesn't see your files, re-select the folder (Step 3)
- Once confirmed, paste the setup prompt again in a new chat
Starting a new chat is important — it clears any confusion from the previous attempt.
Memory between sessions comes from the files in your folder, not from Claude's chat history. Each new session, Claude re-reads _system/context.md to remember who you are.
If it didn't remember you, one of two things happened:
- The context file wasn't saved — open your Arlo OS folder and check if
_system/context.mdhas your name and role in it. If it's still blank, run the setup prompt again and confirm you see Claude writing to the file. - A different folder was selected — make sure you selected the same Arlo OS folder as last time. Selecting a different folder means Claude starts fresh.
The fastest way to get unstuck is to take a screenshot and show Claude what's on your screen. Claude can see exactly what you're seeing and tell you what to do next.
- Mac: Press
Cmd+Shift+4to capture part of your screen, orCmd+Shift+3for the whole screen. It saves to your Desktop automatically. - Windows: Press
Windows+Shift+Sto open the snipping tool.
Then drop the screenshot into your Claude chat and describe what you were trying to do. Claude will walk you through it step by step.
Also check: Mac likes to hide dialog boxes behind other windows. If something feels like it's waiting for you, try clicking through your open windows — there may be a popup asking for your permission that got buried.
Cowork is a feature of the Claude desktop app — it's not available in the browser version at claude.ai.
- Make sure you downloaded and installed the desktop app (Step 1), not just bookmarked the website
- If you installed it, try quitting and reopening the app — Cowork sometimes appears after a full restart
- If you still can't find it, ask Justin — it takes about 30 seconds to show someone where it is
