Can you describe what your local DB looks like and how you interact with it with Claude? This seems interesting, a skill or something with clear rules becomes the app logic and Claude the interface?
I built a few workflows around a notes db in aws, a telegram bot to send quick notes w/o keeping claude up, zotero connectors for literature tracking, etc.
Nothing really beats just "organize this folder and keep track of notes that I share". It'll invent some markdown + tags and that's good enough. Easy to overthink a list of names + maybe .jsonl entries of encounters + maybe a list of factoids. If you need phone access, /rc works fine
