I ran a free prose linter over 31 posts, fixed 25 sentences, and put a check in pre-commit. I also looked at AI detectors and humanizers and skipped all of them.

I linted my own blog for AI-sounding writing. Here is what worked and what I skipped

How I reach the Windows PC that runs my coding agents: Tailscale for ssh and Herdr from my own devices, Cloudflare Tunnel with Access for browser tools from anywhere, and no ports open on my home router.

Tailscale and Cloudflare Tunnel: reaching my home PC from anywhere with zero open ports

How I use Hermes Agent for scheduled jobs, skills and memory: nightly tool updates, model syncs into 9Router, repo audits and self-healing cron, plus a skills habit where every correction becomes a file the agent reads next time.

Hermes: the agent that runs my setup while I sleep, and learns from every correction

Why I wrote 9agent, a small launcher that points Claude Code, Pi or Hermes at a 9Router gateway, lets me pick any model behind it, and optionally runs the agent in Docker. It never rewrites config files and never sits in the middle of a session.
