Summary
This beginner-friendly tutorial from Youri van Hofwegen walks through setting up a personal AI agent from scratch, focusing on two components most tutorials skip: the system prompt (which he calls the “soul file”) and the underlying runtime environment. Youri introduces a free tool called Ordain that generates structured soul.md files through a guided UI — selecting agent type (Hermes), personality, autonomy level, and task categories — and produces a detailed system prompt in seconds that would otherwise take an hour to draft manually.
For the runtime, the video covers deploying the Hermes agent framework on a Hostinger VPS (KVM2 tier, 8 GB RAM), connecting it to OpenRouter for model access, and linking it to Telegram as a messaging interface. The OpenRouter integration is highlighted as particularly useful because it gives the agent access to models including GPT-5.5 and Sonnet 5 (Claude) and allows switching between them with a single command. Youri also recommends setting a monthly spending cap — around $25 — to avoid runaway API costs.
The second half of the video introduces Ordain’s “skill” files, which give the agent task-specific instructions beyond the base soul file, with the claim that these significantly improve output quality on repeated workflows. While the tutorial includes a Hostinger affiliate coupon, the technical steps are reproducible and the Ordain + Hermes + OpenRouter stack is explained clearly enough for someone with no prior agent-deployment experience to follow along.
