Nine Prompts Worth Stealing From Anthropic's Own Guide
9 prompts worth stealing, pulled from Anthropic’s own Claude Fable 5 prompting guide. You saw 3 in the video; here are all nine, each with the exact line to paste. Everything below is written for Claude Fable 5, which follows what you say more literally, and more capably, than the model you are used to.
The whole game with Fable 5 is steering it precisely. These nine moves are the steering wheel: the first three keep it on track, the middle three make the output sharper, and the last three save you tokens and rework. Blocks marked “From Anthropic” are quoted word for word from the official guide.

Use it any time the task is surgical: one bug, one paragraph, one section. It kills the helpful-but-unwanted rewrites.
