Fable written Claude.MD (+Migration) for Opus/Sonnet to act more like Fable
Claude 相关模型动态已经出现，适合跟踪能力变化、生态影响和后续可用性。
为了应对 Claude Opus 在 7 月 7 日后转为 API 专用模式，作者提供了一套名为 FableClaude.MD 的文档，旨在让 Opus 和 Sonnet 模型表现得更接近 Fable 模型的水平。…
Everyone has dropped the tip to have Fable re-write your Claude.MD for Opus to make Opus perform better before it goes API only on the 7th. But maybe you don't have the tokens left or don't want to spend them. And no one I've seen has shared a written/re-written MD
So I had Fable write a portable CLAUDE.md + documentation set that makes Claude Opus / Sonnet operate as close to frontier (Fable) level as possible inside Claude Code: fewer logic errors, fewer introduced bugs, fewer wasted tokens. It works by converting the implicit judgment a stronger model applies automatically into explicit, checkable, event-triggered procedures a weaker model can execute mechanically.

Incase you have a project that is already running with important specifics in your Claude.MD you need to keep there is also a Migration.MD that will help Opus rewrite your current Claude.MD to make it into the Fable written MD and use the Fable style documentation.
Will it be Fable? No. Will it be as good as Fable rewriting your MD? No. Will it be better than nothing for everyone that looks at the calendar on July 8th and goes "Shoot I forgot to have Fable do that". Probably.
