Fable 5 leaves your Claude plan tomorrow July 7. Here's how to keep its intelligence after it's gone. Hi, I'm Nelson. I worked at Shopify for years before leaving to build my own AI company, Solarium. So here's the trick with Fable 5. The model is temporary for free use, but its intelligence is permanent. So before this window closes, have your Fable 5 study your code base, write everything down, and make these three files. Every future session on a cheaper model will start from these notes from Fable 5. With these files, this is what you want it to produce. File 1: a Project Overview. What your app is, how it's architected, why the big decisions were made, the stuff a senior engineer would explain to a new hire. File 2: a Gaps File. Have Fable audit your code base and write down every weakness it finds: tech debt, missing tests, fragile edge cases, security holes. Fable catches things smaller models will miss, and once they're written down, any model can fix them one by one. File 3: Have Fable 5 Expand Your CLAUDE.md. That's the file Claude code reads at the start of every session. Have Fable pack it with deep context it learned so Opus or Sonnet starts session thinking like Fable did. I wrote one prompt that makes Fable do all three on your project in a single run. Comment "FABLE" down below and I'll send it to you. But run it before July 7th. Follow for more Claude code tips.
