Claude Fable wants you to delete your prompts - Guide and skill creation #fable

Anthropic published an official prompting guide for Claude Fable 5 - and its core message is the opposite of what you'd expect: stop adding instructions, start deleting them. In this video, I explain what actually changed (in plain English, no jargon), then do something most people won't think to try: I take the entire guide and build it into a single skill. From then on, you just tell the skill what you want in plain language, and it writes you a fully Fable-optimized prompt - automatically, every time. Anthropic Guide to Fable 5 Prompting - https://platform.claude.com/docs/en/b... You'll see: ✅ Why prompts built for older Claude models can actively hurt Fable 5's output ✅ The 3 real shifts Anthropic recommends, explained simply ✅ A live demo: one rough sentence in, a properly structured prompt out ✅ What "let it prompt itself" actually means - and the honest caveat on what it doesn't This is based on Anthropic's own official documentation. I've checked the core quotes and claims directly against the primary source - where I couldn't verify something (pricing, benchmarks), I say so in the video instead of guessing. 00:00 Fable Needs Less Handholding 00:06 The New Hire Checklist Trap 01:18 Why Old Prompts Fail Fable 03:32 Three Shifts From The Guide 03:54 Shift One Explain The Why 04:41 Shift Two Set Boundaries 05:10 Shift Three Add Checkpoints 05:47 Build A Prompt Writing Skill 08:04 How To Create The Skill 08:40 Live Test Prompt Generator 09:59 What This Does And Doesnt Do 10:38 Wrap Up And Next Steps Here is the skill file - https://limewire.com/d/UtAXo#AhDyTcbBUS #AI #ClaudeAI #PromptEngineering
