How a Bad CLAUDE.md Cost Me Two Days (And What I Built to Fix It)

Fri, 22 May 2026 00:00:00 +0000

I nearly quit my homelab project over a markdown file.

Not a broken deployment. Not a corrupted etcd cluster. Not a misconfigured NetworkPolicy at midnight. A markdown file. Specifically, a CLAUDE.md that described a cluster I no longer had, a roadmap I’d already executed, and a “current state” that was 10 sessions out of date. Every time I opened a new Claude Code session, I was handing my AI assistant a map of the wrong city and wondering why we kept ending up in the wrong place.

I Tried to Secure My Self-Hosted Nextcloud. It Didn't Go Well.

A homelab horror story about an Unraid update, a perfectly fine Nextcloud, and why you should never touch a working system at 10pm.

How It Actually Started #

It started with an Unraid update.

I upgraded my Unraid server to version 7.3 — a routine update, didn’t think twice about it — and the next thing I knew, Nextcloud wasn’t loading. My immediate assumption: something broke in Nextcloud. I had just finished deploying it to my K3s cluster, moved on to other homelab chores, and came back to find it dead.
