We're analyzing your mode of working with AI. There are real tradeoffs, but don't worry — everything is changeable. This is not a major decision.
You'll be deciding where your first Project lives, so you can start working with Projects effectively. You'll also be using your first Skill along the way — don't worry about what Skills are yet. That'll come soon.
This file is the entire Skill. It's a single Markdown document. Either download it to your computer, or copy the text and paste it into a new file yourself — both work the same way.
About 70 lines of plain-English instructions. Claude reads it, runs the three-question diagnostic, and gives you a recommendation.
Walk through these in order. If you've never uploaded a file to a Claude chat before, that's fine — we'll go slow on that step.
Scroll up and click Download Skill. The file will land in your Downloads folder. It's named project-placement-advisor-SKILL.md — leave the name as-is.
If you'd rather not download anything, click View / copy text instead, copy everything, and paste it into a new file on your computer. Save it as project-placement-advisor.md.
On Mac, open Finder and look in Downloads. On Windows, open File Explorer and check Downloads. The file is small — a few KB.
Go to claude.ai in a new tab. Sign in if you're not already.
You can do this on the Claude desktop app instead — the steps are identical. Use whichever you prefer.
Click New chat in the left sidebar (or the + icon if your view is collapsed).
Do not open this inside an existing Project. We want a fresh, empty conversation. The Skill works in a regular chat — Projects come after the recommendation.
At the bottom of the chat window, you'll see a text box. To the left of where you type, there's a paperclip icon or a + button — that's the attach button.
Click it, then choose Upload from computer (or just drag the .md file from your Downloads folder directly onto the chat window). You'll see the file appear as a small attachment above the text box.
Make sure you're on Claude on the web or desktop app — not the mobile app. Mobile attachment flow is similar but the icon may be hidden inside a "+" menu next to the message box.
With the file attached, type this exactly into the chat and send:
That's it. Claude will read the Skill, recognize it as a diagnostic, and start asking you the three questions.
Claude will ask one question, wait for your answer, then ask the next. Answer honestly — short answers are fine. The whole exchange should take under a minute.
Here's roughly how the conversation will go:
Help me decide where to set up my first Project. Use the attached skill.
Where do you actually use AI most — primarily on mobile and web, or primarily on a desktop computer?
Mostly desktop, but I check things on my phone too.
Do you need seamless access across mobile, web, and desktop — or is desktop-first acceptable to you?
Desktop-first is fine.
Do your AI sessions typically go straight to producing something — a document, spreadsheet, or built output — or are they mostly thinking and conversation?
After the third answer, Claude will give you a clear, one-line verdict: set up your first Project in Chat, or set up your first Project in Cowork. Two or three sentences of reasoning. One sentence on what to do next.
That's the whole Skill. Done in under a minute.
In case you want to think about them in advance — though honest, gut-level answers tend to be more accurate than rehearsed ones.
That's the next module.
You downloaded a Skill file, attached it to a Claude chat, prompted Claude to use it, and got a structured output back. That's the entire Skill mechanic. Every Skill in the program works exactly this way — only the playbook inside changes.
Once your Project is set up, you'll start dropping Skills into it directly so they're always available. For now, the file-upload-per-chat method is fine. You've got the muscle memory.
