terraform-hcloud-kube-hetzner: Skill for Claude Code

.claude/skills/sync-docs/SKILL.md

sync-docs is a skill for Claude Code from mysticaltech/terraform-hcloud-kube-hetzner. It costs 29 tokens per session (2,818 once invoked), scanned A, original, MIT.

A documentation-maintenance checklist for keeping configuration references and examples consistent across a project. It treats the main variable definition file as the source of truth.

In plain words
What is it for?
Use it after variable or feature changes to synchronize Terraform references, examples, migration guides, the README, and operational documentation.
Why use it?
It prevents users from finding different variable names, values, or upgrade instructions in different documents. Related documentation is updated together when configuration changes.

Skill for Claude Code

Written for Claude Code: installed under .claude/. Also seen: reads .claude/ paths; positional $N argument.

This is mysticaltech/terraform-hcloud-kube-hetzner's own configuration. It tells Claude Code how to work on terraform-hcloud-kube-hetzner itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything terraform-hcloud-kube-hetzner configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run scripts/validate_v3_final_polish_examples.py.

About the project

Kube-Hetzner is an infrastructure project that uses Terraform or OpenTofu to deploy and maintain Kubernetes clusters on Hetzner Cloud. It is for operators who need highly available clusters based on k3s or RKE2, with networking, storage, ingress, certificates, and upgrades configured as part of the deployment.

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

sync-docs 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 9d 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.

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.
