I created my first three-file folder system for PC-Maintenance My CLAUDE.md included an IT Technician helping me troubleshoot, maintain, and repair my PC. My CONTEXT.md explained Workspace Routing & Current Status. My REFERENCES.md provided Repository of useful resources, examples, and reference material from completed projects. When I asked Claude what improvements do I need to make first, the response was different because I got clearer improvement suggestions with rationalizations. Before, I had to explain the kind of improvements I was looking for every time. Now Claude already has that information. Key takeaway: Context affects the output a great deal
