every month you use Claude Code, your CLAUDE.md gets longer and worse at the same time. - one-off corrections harden into permanent rules. - context ages out. - you contradict a line you wrote and forgot. - nobody audits any of it. Dreaming is the audit: it reads up to 100 past sessions and rewrites the memory file from what you actually did, not what you once typed. here's what nobody says out loud: > the raw material it needs already sits on your disk as JSONL > the official version is gated behind Managed Agents, enterprise-priced > the mechanism itself is 80 lines of Python and a 12-line rubric i didn't request access. i rebuilt it over a Saturday morning and ran it on 90 days of my own sessions. one Opus call and out came a 38-line memory file. 73% of my old CLAUDE.md deleted. four behavior patterns surfaced that i had never written down, including one where i correct Claude's prose 8.2x more than its code. watch the keynote for what shipped. read the article for the version you can run tonight. your CLAUDE.md isn't too short. it's too old.
