open-homelab: Skill for Claude Code

.claude/skills/open-homelab-aws-bringup/SKILL.md

open-homelab-aws-bringup is a skill for Claude Code from open-homelab-io/open-homelab. It costs 67 tokens per session (786 once invoked), scanned A, original, Apache-2.0.

A guide for adding AWS features to Open Homelab, a self-hosted home server setup managed with infrastructure code. It covers cloud storage for OpenTofu state and Route53 DNS automation.

In plain words
What is it for?
Use it to configure S3 OpenTofu state, Route53 DNS, IAM Roles Anywhere, ExternalDNS, DNS-01 certificates, or public ACME certificates in Open Homelab.
Why use it?
It explains how to add AWS-backed state and DNS while keeping those optional features separate from the local-only cluster setup.

Skill for Claude Code

Written for Claude Code: installed under .claude/.

This is open-homelab-io/open-homelab's own configuration. It tells Claude Code how to work on open-homelab 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 open-homelab configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cd ../proxmox.

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

open-homelab-aws-bringup 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 12d 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.

Open Homelab AWS Bring-Up

Use this skill only for AWS add-ons. The base cluster still comes online through the local/no-AWS path unless the user explicitly wants AWS features.

Read First

  • docs/deployment-modes.md
  • docs/configuration.md
  • infra/aws/README.md
  • bootstrap/secrets/README.md
  • clusters/production/gitops/README.md

AWS has two independent paths: S3 OpenTofu state and Route53 DNS automation.

Do not enable AWS DNS automation implicitly; it creates real AWS IAM and Route53 resources.

AWS OpenTofu State

Required .env values:

AWS_OPENTOFU_STATE_ENABLED=1
AWS_REGION=us-east-1
TF_STATE_BUCKET=open-homelab-opentofu-state-123456789012-us-east-1
TF_STATE_KEY=open-homelab/proxmox/production.tfstate

Deploy:

cd infra/aws
bun install
AWS_OPENTOFU_STATE_ENABLED=1 bun run typecheck
AWS_OPENTOFU_STATE_ENABLED=1 bun run synth
AWS_OPENTOFU_STATE_ENABLED=1 bun run deploy open-homelab-opentofu-state

Migrate existing Proxmox state only after the bucket exists:

cd ../proxmox
bun run synth
cd cdktf.out/stacks/production
set -a; . ../../../../../.env; set +a
tofu init -migrate-state
tofu plan

AWS DNS Automation

Required .env values:

AWS_DNS_AUTOMATION_ENABLED=1
AWS_REGION=us-east-1
PUBLIC_DOMAIN=example.com
PUBLIC_HOSTED_ZONE_ID=Z00000000000000000000
CLUSTER_DOMAIN=lab.example.com
[email protected]

Use .env.example for the full IAM_ROLES_ANYWHERE_* defaults. Before deploying, require the user to replace placeholders in platform/dns/cluster-issuers.yaml, platform/external-dns/values.yaml, and platform hostname values under platform/*/values.yaml.

Deploy:

scripts/bootstrap-rolesanywhere-ca.sh
cd infra/aws
AWS_DNS_AUTOMATION_ENABLED=1 bun run typecheck
AWS_DNS_AUTOMATION_ENABLED=1 bun run synth
AWS_DNS_AUTOMATION_ENABLED=1 bun run deploy open-homelab-dns-automation
cd ../..
scripts/bootstrap-rolesanywhere-dns.sh

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.
