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.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00233 | $0.05356 |
| Opus 5 | $0.00117 | $0.02678 |
| Sonnet 5 | $0.00047 | $0.01071 |
| Haiku 4.5 | $0.00023 | $0.00536 |
Grade D, and why
ubuntu-bootstrap scanned grade D with 2 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
This is the **one** interview phase. After Phase 1 inventory interview the skill auto-fills everything the rest of the flow needs and presents a single consolidated summary; later phases (ansible-playbook prepare-sudo / Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
Offer optional merge into `~/.kube/config` via `kubectl kc add --file "$CONFIG_DIR/kubeconfig.yaml" --context-name "$CLUSTER_CONTEXT" --cover`. Default: keep standalone — `$CONFIG_DIR/kubeconfig.yaml` is gitignored, the How it starts
The opening of the file, as written. The whole thing — 377 lines — stays where its author put it; the contents beside it link to each section on GitHub.
cozystack:ubuntu-bootstrap
Work in reasoning mode. Use the phrasing cozystack:ubuntu-bootstrap. Announce phase transitions: cozystack:ubuntu-bootstrap Phase N — <name>.
Note on language in this SKILL.md — every operator-facing prompt below is written in English for clarity. At runtime the skill matches the operator's natural language detected from prior conversation messages (or read from
<config-dir>/.state.yamloperator_languagewhen the wizard chain is in progress). Code identifiers, commands, file paths, and any text destined for GitHub stay canonical. Ansible task names from upstream playbooks come through in English by design — don't translate them.
Why this is an ansible wrapper, not a hand-rolled SSH flow
cozystack/ansible-cozystack/examples/ubuntu/ already implements every node-prep step Cozystack needs — and that list is non-obvious and broad: 11 sysctl keys, 8 kernel modules across required / optional / DRBD / ZFS / KubeVirt categories, LINBIT PPA wiring for drbd-dkms on Secure Boot, multipath blacklist for drbd* devnodes, iptables flush for cloud images that REJECT non-SSH traffic, Ubuntu 26.04 sudo-rs workaround. A hand-rolled SSH shell skill drifts from this list the moment ansible-cozystack adds anything new. Wrapping the playbooks keeps ubuntu-bootstrap aligned by reference.
The wrapper does not call the cozystack-install step from upstream site.yml — that lives in cozystack:cluster-install so the storage / extractedprism / OIDC / domain logic stays in one place. The skill renders an inventory with cozystack_create_platform_package: false to enforce this.
Cluster config directory
Every artifact lives under <config-dir>/. Default resolution (read from state.config_dir written by cozystack:wizard):
<config-dir>/
.gitignore # skill-managed: excludes secrets + state
.state.yaml # wizard chain state (read+write by every skill)
inventory.yml # ansible inventory rendered by this skill
kubeconfig.yaml # k3s kubeconfig after Phase 8 (server URL rewritten)
What ships with it
3 files beside SKILL.md 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-bootstrap is a skill published in the GitHub repository cozystack/ccp (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 233 tokens to every session and 5,356 once invoked, about $0.0012 per session on Opus 5. A static security scan graded it D with 2 findings (asks for root, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
