Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

ubuntu scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 24d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

"description": "Ubuntu Server provisioning suite — the three configuration layers of an unattended on-premise / air-gapped Ubuntu Server LTS 24.04 / 26.04 bring-up: ubuntu-autoinstall (the Subiquity `autoinstall:` v1 schema — identity, storage LVM/ZFS/RAID/encryption, apt mirror + proxy + offline fallback, early/late-commands, NoCloud zero-touch delivery), ubuntu-cloud-init (NoCloud-datasource `#cloud-config` user-data — users, ssh, write_files, runcmd, local apt mirrors, internal-CA ca_certs, seed ISO / SMBIOS serial / `ds=nocloud` cmdline, boot stages, `datasource_list` pinning), and ubuntu-netplan (the `/etc/netplan/*.yaml` v2 network substrate both share — static addressing, bonds, bridges, VLANs, VRFs, policy routing, predictable interface naming, systemd-networkd renderer). The installer's `network:` block is netplan and its `user-data:` block is cloud-config, so the three are designed to be used together.",

}What it installs
The manifest is a name and a version. 3 skills travel with it, and installing the plugin installs all of them — 435 tokens a session between them. Each is measured on its own page, and each can be installed alone.
What ships with it
1 file beside marketplace.json#ubuntu in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

ubuntu is a plugin published in the GitHub repository air-gapped/skills (5 stars, last pushed 2d ago), licensed MIT. Its token cost is not measured: this kind of file is read by the harness, not the model. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
