# Summary The core argument is that most people approach Claude wrong. They treat it like a search engine—write a prompt, get an answer, move on. Anthropic's engineers work differently. They build reusable systems: organized folders with focused instructions and scripts, connected through slash commands and agents. The author watched talks from Anthropic engineers at a May 2026 event and realized his entire SEO workflow—a sprawling 600-line document crammed into one file—was backwards. He split it into six focused files (research, audit, metadata, internal links, GSC monitoring, title scoring), wired them together, and now when he improves one skill, every workflow using it automatically gets better. That's the compounding advantage Anthropic's people keep talking about. The shift is from prompting to system design. When you write a one-off prompt, you get a one-off result. The value evaporates when the session ends. When you build a skill—a folder with a SKILL.md file, scripts, and references—Claude runs it the same way every time, and you improve it after each failure. Six months in, it's doing work your day-one self couldn't have even imagined. The author groups Anthropic's tactics into six layers, with the first being the most important: stop writing custom prompts for repetitive tasks. Build skills instead. Invoke them with a slash command. Run the same task the exact same way every single time. This is where your time actually accumulates into something that matters, not in the prompt itself but in the infrastructure you build on top of what Anthropic provides.
