cluster-upgrade

A guided procedure for upgrading a running Cozystack version 1 cluster to a newer version 1 patch or minor release. Cozystack is a platform for running Kubernetes-based cloud services.

In plain words
What is it for?
Use it to review release notes, prepare and approve an upgrade, run the Helm upgrade, perform post-upgrade health checks, and verify tenants.
Why use it?
It focuses checks on the components changed in the target release instead of relying only on general health checks.

Token cost

What it costs to keep this loaded

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.

Security

Grade A, and why

cluster-upgrade 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 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.

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.

How it starts

The opening of the file, as written. The whole thing — 182 lines — stays where its author put it; the contents beside it link to each section on GitHub.

cozystack:cluster-upgrade

Guided upgrade of a running Cozystack v1.x cluster. Source of truth: https://cozystack.io/docs/<vX.Y>/operations/cluster/upgrade/ (substitute the version selector value matching your target — e.g. v1.3).

Core principles

Release-notes-driven upgrade. Every release changes a specific set of components. Generic "all green" checks miss regressions in the areas that actually changed. Read the target's release notes, extract the change list, and run targeted pre/post checks — not just the default health checklist.

Match the operator's natural language. Detect from prior conversation messages (or read <config-dir>/.state.yaml operator_language if a wizard chain is in progress). Use it in every prompt, AskUserQuestion option, summary, and gate. Never ask "what language?" separately. Code identifiers, commands, file paths, and GitHub-public text stay in their canonical form.

One valid path → just do it. After the operator approved the risk summary at the upgrade stop gate, the skill runs helm upgrade + post-upgrade health checks + tenant verification back-to-back. Approval gates remain only for the named STOP GATEs in the workflow (risk summary, helm upgrade itself, final report) and for any rollback action (always destructive-risky).

Front-load the interview. Read the cluster + release notes + pre-flight checks up front and surface a single risk-summary screen with the upgrade plan, change-list, and any blockers. Approval of that screen is the only interview gate — subsequent phases (helm upgrade, post-upgrade checks) execute without re-prompting.

Layer-pure operator output. The skill never says "returning control to wizard" or any other orchestration commentary in the operator-facing summary. Whoever invoked the skill (a human directly, or a chain orchestrator) figures out what's next on their own. Internal documentation references are fine; wizard does not appear in text shown to the operator.

What ships with it

5 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.

Changes

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.

cluster-upgrade is a skill published in the GitHub repository cozystack/ccp (4 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 40 tokens to every session and 2,511 once invoked, about $0.0002 per session on Opus 5. 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 2026-08-31.
