A reproducible workflow to (1) curate high signal expert sources, (2) synthesize them into a structured guidebook with NotebookLM, (3) restructure that guidebook into a Claude Project knowledge base, and (4) run an iterative learning loop that produces durable, exportable artifacts. The workflow is optimized for clarity, copy paste prompts, and parallelizable work where possible. Recommended project folder (optional but helps reproducibility): 01 domain/ (domain brief) 02 sources/ (source list, PDFs, links) 03 notebooklm/ (notebook export notes) 04 guidebook/ (v0, v1, changelog) 05 claude project/ (system prompt, uploaded files list) 06 outputs/ (artifacts, summaries, checklists) Source: master anything by owning your own expert
