Anthropic Just Revealed 5 New Rules for Prompting Claude 5 Models

Anthropic put out five official guides on how to use Claude, and a lot of what worked before (long rule lists, pasted examples, loading every file up front, max effort, teams of agents) now costs you more or gets in the way. I read all five and fixed one example setup, a Monday client report, one guide at a time. 👉 Get the summary of the rules & the prompt to improve your setup here: https://www.skool.com/barts-ai-workshop-4507/about Go to YouTube Resources and search: 'The 5 New Rules For Claude' 👉 Work with me: https://workingmodels.ai/start 👉 Connect with me: https://x.com/bartslodyczka 🏆 Support the channel: https://www.youtube.com/channel/UC8F7X90NDmMr1mGx8897r_A/join The checklist: 1. Prompting: give the whole job in one message; delete "double-check" lines. 2. Context: run /doctor; cut CLAUDE.md down to the gotchas. 3. Skills: move reference material into linked files, one level deep; write a "use when" description. 4. Effort: default to medium; draft on low, verify on high. 5. Agents: fold one agent into a skill; test on 10 examples, twice.
