As mentioned in Week 1, the following section will cover the process of planning a 15,000-line prompt that collects information about the US-China semiconductor tariff policy using Claude and organizes it into a timeline. However, I didn't actually use Claude from the beginning. While researching various AIs to build an automated trading system and develop a profitability verification program, I discovered Claude through a recommendation from a developer friend.
Then, around June 2025, I happened to see a YouTube video praising Claude's Model Context Protocol (MCP). I learned that various features could be added with simple configuration.

Initially, I tried out all the popular MCPs available, and one of them was Sequential Thinking.
The first time I used Sequential Thinking, I was shocked. "Can you see how AI thinks?" When you ask a complex question, AI doesn't immediately answer. Instead, it goes through a multi-step process of thinking and reviewing.
"First thought: What is the essence of this question?”
"Second thought: Is this the best way to do it? Is there another way?”
