“Guys, 2CRSI may be a fraud.”

That message showed up last week in our investor group.

The stock was up almost 10x in a year on AI hype.

Everyone was talking about it on X.

Then the short-seller report came out.

A few days later, the stock was down 50%.

That’s when I asked myself:

Why wait for the short seller?

Why not make Claude run the short-seller check for any stock.

So I built a Claude agent for that.

In one click, claude will:

  1. Check filings and numbers: cash flow, receivables, debt, margins, and related-party red flags.

  2. Compare the management story with what the numbers actually show.

  3. write a short-seller report: what looks strange, what needs proof, and what could break the thesis.

The output is an interactive page you can export into a doc like this one:

You can download the agent, copy it, and run it every time you doubt


How the Claude Short-Seller Check Works

99% of stocks are not frauds…

But you only need to be trapped once to lose a lot of capital.

That’s why I built this Claude Skill like a small investigation team.

You give it one company.

Claude sends 3 detectives into the stock.


Detective 1: People Check

this one answers a simple question

Can you trust the people running the company?

It looks for past scandals, lawsuits, insider selling, strange related-party deals, and signs of self-dealing.

Because fraud usually starts with people.

Detective 2: Numbers Check

The key question:

Are profits showing up in cash?

Or only on paper?

Detective 3: Real World Check

Does the business exist at the size management claims?

Because a company can tell a beautiful story.

But factories, stores, customers, and cash are harder to fake.

At the end, Claude gives you a short-seller report:

  • What looks strange

  • What needs proof

  • What would make the fraud case stronger

  • What would prove the short thesis wrong


How to Install the Claude Short-Seller Agent

To use this agent, you need Claude.

The idea is simple:

  • Download my file.

  • Upload it into Claude.

  • Then use it every time you want to check a stock for red flags.
