I’ve been using AI for investing for more than a year.

And from the outside, it’s hard to tell the difference between:

• a random prompt from someone who never seriously analyzed a stock

• and a real workflow built by an investor, tested across multiple stocks.

The difference is the structure behind it:

This is not one giant prompt asking Claude to “find risks.”

It’s a small research system inside Claude:

1. One main instruction file :It tells Claude the job, the rules, the ranking logic, and the final memo format.

2. Three tested investing prompts: These are prompts I had already refined and tested for 8+ months in my investing process.

• Business risk: what could weaken the operating engine

• Financial risk: what could stress cash flow, dilution, or the balance sheet

• Structural / external risk: what outside forces could change the economics

3. One synthesis step Claude merges the three passes into one ranked Stock Risk Audit.

So the skill is not magic.

It is:

one main instruction file + 3 tested prompts + one final risk memo.
