Building a second brain with GPT-6 Astra and Codex
The author shows how to set up a three-directory knowledge base with an AGENTSmd routing map so every new project reads all prior notes before starting.
SOMEONE BUILT A SECOND BRAIN WITH GPT-6 ASTRA AND NOTHING HE BUILDS STARTS FROM SCRATCH ANYMORE, EVERY NEW PROJECT READS 378 PAGES AND 1,816 LINKS FIRST every dot on that screen is one thing he's written down, every line between them is a connection it follows instead of searching it only gets stronger the more he adds, every new file connects into the ones already there instead of getting buried in a search you don't need a smarter model, you need one that's already read your goals, your clients and the decisions you made last year the setup is short: > three directories in one place: raw, entities, concepts > drop in what you already own, transcripts, notes exports, client files > let Codex interview you out loud and write the rest > a routing map in AGENTSmd so it knows where to look > a nightly pass that folds each new file in it's the same subscription and the same model everyone else is running, you just never have to explain yourself to it again the article below shows how to build it and wire it into everything you make
