nix-config-new-hostA skill your agent uses when adding a NixOS, macOS, or MicroVM host in this repo, or wiring an existing machine into outputs/, hostsAddr, secrets recipients, and the eval tests.
Nix Config New Host is an agent skill from ryan4yin/nix-config. Use when adding a NixOS, macOS, or MicroVM host in this repo, or wiring an existing machine into outputs/, hostsAddr, secrets recipients, and the eval tests.
Its SKILL.md is about 1.6k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Development. It works with macOS and Linux. The repository describes itself as: ❄️ My nix config for both desktops(NixOS+macOS) and homelab servers(NixOS). The licence is MIT.
5 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 497fabb. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
justsshFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use ssh, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Nix Config New Host loads about 1.6k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 799 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

hosts/idols-ai/), the hostname
(hostName = "ai"), and the configuration name (ai-niri) differ. Servers use the hostname as
the configuration name; Niri desktops append -niri, because just niri deploys
$(hostname)-niri. The hostname eval test encodes this.nix-secrets; see the nix-config-secrets skill. A new desktop also needs its

outputs/x86_64-linux/src/k3s-test-1-worker-1.nixA MicroVM guest is also registered in its VM host's microvm.nix; deploy it with the procedure in
WA-026 of WORKAROUNDS.md, not just microvm-deploy. On a VM host with
the br0 bridge it also needs a systemd.network.networks unit that attaches the guest's tap to
br0; the tap name comes from the guest IP (192.168.5.116 to vm116). Some guest outputs also
expose a Colmena node for evaluation or other workflows; do not assume the physical-host deployment
is done through Colmena.
hosts/<dir>/default.nix - sets hostName and imports the host's modules. Some hosts (shoryu,
shushou, youko, akane) import mylib.scanPaths ./., which pulls in every other .nix
file in the directory; keep scratch files out of those.hosts/<dir>/hardware-configuration.nix - generated on the target machine
(nixos-generate-config --show-hardware-config), never copied from another host. Where the
layout is declarative, add disko-fs.nix and record the install command in the host's
README.md, as hosts/idols-ai/README.md does.home/hosts/linux/<name>.nix or home/hosts/darwin/<name>.nix - only for a host with Home
Manager; otherwise leave home-modules out.outputs/<system>/src/<name>.nix - add the output types appropriate to the host:
nixosConfigurations.<name> for NixOS, darwinConfigurations.<name> for macOS, and a
packages.<name> installer image only where the platform provides one. Add colmena.<name> only
for a host deployed through Colmena; it then needs tags, ssh-user, and usually targetHost.
MicroVM guests also need the VM-host microvm.nix registration. Keep the leading comment about
unused args: haumea passes them lazily and they are still required.vars/networking.nix - hostsAddr.<name> = { iface; ipv4; } for a LAN host. That entry drives
the static address, the SSH Host alias used for remote builds, and known_hosts, so a wrong
iface takes the host offline at activation. Skip it for a DHCP or mobile host;
homeOnly = true only drops the SSH alias and the local exporters, not known_hosts or the
scrape targets. If the host enables modules.networking.mihomo and runs systemd-resolved, it
needs a DNS takeover tied to mihomo's lifecycle (resolvectl dns/revert in
ExecStartPost/ExecStopPost, see hosts/idols-ai/default.nix); a static link DNS would kill
DNS when mihomo dies.hosts/README.md - add the host to the inventory.Pin service user and group ids (service-user-ids.nix, as on shoryu) before the host has state on
disk. A dynamically allocated id that moves on a later rebuild orphans the files it owned
(9187e4d9 fix(youko): pin dynamically-allocated service uid/gid (#320)).
outputs/README.md lists which eval tests check every configuration and which list hosts by name:
hostname: a new -niri configuration needs a specialExpected entry, in the test for its
platform (ai-niri in x86_64-linux, shoukei-niri in aarch64-linux).security-*, kernel, nix-system-features: apply to every configuration automatically.home-manager, btrbk, and the other host-listing tests: add the host if it should be covered.just test fails (non-zero) unless the suite returns true.
lsblk/findmnt first, name the exact device, and get authorization for it
before any destroy,format,mount. Follow
nixos-installer/README.md and the host's own README.just col <tag> or the host's own recipe, once its key is a secrets recipient.
Deploying is a separate impactful action; use the nix-config-update skill's staged deployment
(confirm the target, preview the closure, and get authorization).just local or just niri.ssh <name> true, then systemctl --failed and journalctl -b -p err on the host.© ryan4yin, MIT.

Going by SKILL.md and its folder, Nix Config New Host needs the command-line tools its instructions call (just and ssh).
SKILL.md contains no URLs. Its commands use ssh, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Nix Config New Host is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
