Prospect Grader
Deep-researches every company on your list and grades them green, amber or red, so you know who to chase and who to skip.
If you've already got Claude Cowork installed and you're on a paid plan, skip the setup and just grab the skill.
Download the skillThe full setup guide is right below. It only takes a few minutes.
If you don't have the Claude desktop app, you'll need it first, so download it here.
(You'll also need Claude Pro, around $20.)
Install Cowork
Download the Claude desktop app and sign in on a paid plan. It has to be the desktop app, not the browser, because that is the version that can read your files and connect to your tools.
Open Cowork and give it a folder
Cowork is where Claude actually does work on your computer, not just chat. Get in and point it at one folder:
- Open the desktop app and switch to Cowork, the middle of the three modes at the top.
- Click New Task, then Work in a Project, then Choose a folder.
- Make a fresh, empty folder (I call mine Claude Playground).
Claude only ever sees that one folder, nothing else on your computer, and it uses it to save your sales brain and your data. So it stays private and tidy.
Install the skill
A skill is a saved set of instructions Claude follows every time. You install it once, then it's yours.
Download the skill- It saves a small file, prospect-grader.skill, to your Downloads.
- In a new Cowork task, drag the file into the chat, then click the Save skill button that appears on it.
- Check it worked: click + at the bottom of the chat, then Skills. You should see it listed.
You only do this once.
Run it
- Open a New Task in your project folder.
- Click + > Skills > prospect-grader, or just say grade these accounts.
- Give it your list: paste the company names or websites, or drop an Excel or CSV (it reads your List Builder file directly).
What you get: a ranked list opens in Live Artifacts, every company graded Strong, Fair or Longshot with whether the right buyer is reachable; click any row for that company's full cheat sheet. It needs your sales brain set up to grade them.
How long it runs: the 10 minutes above is setup. The run itself depends on your list, because every company gets a full research pass, five at a time. Roughly 20 minutes for 20 accounts, an hour for 100, and a book of 1,000 is an overnight job. It tells you the estimate before it starts, and it picks up where it left off if you stop it.
Before you finish (quick checks)
