Use My Three Rules to Make Your Claude 100X Better in 12 Minutes

The person who built Claude Code says there is nothing secret about prompting anymore, and Anthropic deleted about 80% of Claude Code's own system prompt with no loss on their coding tests. So the long prompts and the rules files many of us built up for months may be holding Claude back. In this video I give you the three rules that replace all of that, each one shown working on a real task. I use one task for the whole video, turning a long video into a newsletter, and it works the same in the Claude app and in Claude Code. Then I test it on my own setup. My CLAUDE.md rules file was 8,129 words. I cut it almost in half with Claude and ran 15 test runs on each version. Every task that had a pass or fail check still passed, my rules dropped from 39% to 24% of Claude's first read, and the short version cost 10.6% less. It also dropped a few things I needed, and I show you what and how to catch that. You also get three free tools: a rules slimmer, a usage meter and a poll guard. Two of them helped me cut my video editing pipeline from about $145 to about $59 a run. The kit page, with the newsletter prompt, the pass/fail checklist and the three tools, is the first link below. 🎁 Free starter kit from this video, sent to your inbox: https://www.genaiunplugged.com/kit/claude-prompting-three-rules/ A note before you try this Every number in this video comes from my own runs on my own rules files and one video editing pipeline. Claude writes different output each run, so your numbers will move. The test used writing tasks, so it says nothing about whether dropping coding rules hurts code work. Try the slimmer on a copy of your rules file first, and read the list of what it dropped before you say yes. 🎁 Free Claude Code starter kit, sent to your inbox: https://genaiunplugged.substack.com/subscribe 🆓 Free live lesson with me: https://www.genaiunplugged.com/free-lesson/ 🎓 Claude Code Builder, my 6-week live cohort: https://maven.com/genaiunplugged/claude-code-builder 👥 Train your team on Claude Code: https://www.genaiunplugged.com/team-training/ Questions or feedback: support@genaiunplugged.com 📺 CHAPTERS: 0:00 Is prompting dead for Claude? 0:27 Boris Cherny's Claude Code prompting post 2:18 Rule 1: the Claude prompt line most people skip 3:30 Rule 2: the Claude setting that changes every answer 6:13 Rule 3: make Claude prove its work 7:57 I cut my CLAUDE.md in half: the test results 10:31 3 free tools to save Claude Code usage 🔗 RESOURCES Claude Code → https://claude.com/product/claude-code Anthropic, the new rules of context engineering for Claude 5 models → https://claude.com/blog/the-new-rules-of-context-engineering-for-claude-5-generation-models 📥 Helpful Links: ▶️ Watch my Claude AI Full Course 2026 → https://youtu.be/hVRjUvjDQwE 🎓 Learn with me on Maven → https://maven.com/genaiunplugged 🌐 Subscribe to GenAI Unplugged Substack → https://genaiunplugged.substack.com/ 🤝 Let's connect on LinkedIn → https://www.linkedin.com/in/dheerajsharma14/ 📚 Browse all my courses → https://genaiunplugged.com/ 🛠️ Check my AI Systems store → https://store.genaiunplugged.com/ 🙌 A like is what tells YouTube to show this to the next person looking for the same fix.
