8 battle-tested prompts to run before Claude Fable 5 sunsets

分享8个Claude Fable 5下线前必跑的超实用Prompt

The author collected 8 prompts tested repeatedly before Claude Fable 5 sunsets. The /goal prompt ran 25 autonomous experiments, costing $165, and delivered a 50% build-speed gain with 60% lower token cost. A work-mode prompt turns user habits into reusable Skills; an action-norm prompt constrains subagent behavior; a subagent-allocation prompt handles smart task routing. Also included: 25 scheduled loop workflows, autonomous run with auto-pause, a memory system that keeps an error log, and a reverse-interview prompt that requires 95% confidence before execution. The prompts remain usable after API billing kicks in. The core idea: make the model study the user instead of capping its capabilities.

Why it matters: A prompt collection backed by real spend and measured results — not fluff. But it's personal experience sharing, not an official update or industry event, so the score sits right at the featured threshold.
