The playbook
The run starts read-only: the recon probes decide what happens next. The steps that follow are adapted to the distribution and state found — a real machine is rarely clean.
- 01reconAdGuard Home already installed? (then verify and skip)
- 02reconwho holds port 53 (systemd-resolved?) and port 3000
- 03reconcurrent server resolver (must keep working)

What it verifies
Each step ships its own check. The run only moves on when the check passes, so what the recipe reports as done is what is actually on the server.

Guardrails
Non-negotiable instructions the run must respect, whatever it finds on the server.
Never break the server connectivity: no change to the default route, /etc/resolv.conf or the rules that let the Servor agent and the SSH session out. Compare the default route and DNS resolution before/after. Never point the server's resolver at AdGuard Home (no DNS=127.0.0.1 in resolved). No `curl | sh`. Tell the user to finish the wizard through `ssh -L 3000:127.0.0.1:3000`, keeping the web UI on 127.0.0.1:3000 and DNS on a LAN/VPN IP: never open port 53 publicly (open resolver).

How a recipe runs in Servor
Servor is zero-knowledge: the platform cannot execute anything on its own. When you launch this recipe, a run reads the reconnaissance, plans the steps and asks for your approval. Each approved command is signed by your browser — with a key the server never sees — then relayed verbatim to the agent, which verifies the signature locally before executing.
search by intent — type “firewall”, get ufw
- 01Read-only reconnaissance before any change
- 02Every command signed by your browser, approved by you
- 03Each step verified before the run moves on, every run kept in the history
