Last post was the concept. This one's the build. Took a coaching business (Apex Coaching) and built the entire AI Operating System from scratch, on camera. No head start, no template folder just an empty directory and one company overview file. - Connect the folder to Claude, drop in that one file - It reads it and writes its own CLAUDE.md + a blank .env for credentials - Dump in the raw stuff — signups, DMs, session notes, student roster and it sorts itself into department folders: onboarding, support, progress tracking, content. Each one gets its own CLAUDE.md. Then I turned the actual work into skills, so you're not re-explaining yourself every session: - Onboard New Student — Drafts a personalized welcome per signup, flags what needs a human first (missing email, timezone conflict, duplicate contact) - Triage Support DM — Reads the DMs against the roster and session notes, drafts replies in your actual voice, flags anything that's a judgment call instead of guessing - Generate Progress Report — Clean HTML report on who's on track, who's at risk of churning, and the wins worth bringing to a team meeting That last one's now scheduled to run itself every Monday at 9am. I don't touch it. Same folder, same structure. Works with Claude Code, cowork, or codex — pick whichever CLI agent you're running. Next video: content and repurposing. If you have any question, ask me in the comments section.
