Claude Fable 5 can turn a messy workspace into a real second brain, but only inside Claude Code. Learn the four core layers apps, routines, memory, and skills, a ready to use prompt, and how retrieval finds the right file before Claude reads a single line. 📚

We'll talk about:

• Why a second brain needs structure, not just storage
• The four core layers: apps, routines, memory, skills
• Why this workflow runs in Claude Code, not Claude chat
• A ready to use prompt for building your own second brain
• How retrieval finds the right file before Claude reads anything
• Reference projects worth studying before you build (QMD, GBrain)
• How to test speed and token cost properly
• Common mistakes that make a second brain useless
