What it does

Hetzner Storage Box is an agent skill from HybridAIOne/hybridclaw. Read and operate Hetzner Storage Boxes through Hetzner API management calls and WebDAV file requests with gateway-injected credentials.

Its SKILL.md is about 2k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files, including reference files (for example `evals/scenarios.json` and `references/operator-setup.md`).

The repository describes itself as: Enterprise-ready self-hosted AI assistant runtime with sandboxed execution, secure credentials, approvals, and memory. The licence is MIT.

Example prompts

  • “/hetzner-storage-box”

Requirements

  • Python 3
  • A credential in HETZNER_API_TOKEN
  • A credential in HETZNER_DNS_API_TOKEN

Workflow steps

9 steps, taken from the first numbered list in SKILL.md.

  1. Use Hetzner API reads (list-storage-boxes, get-storage-box) for inventory
  2. Use WebDAV reads (list-files, download-file) for file inspection.
  3. Use plan before any management, file write, or public-link request.
  4. Treat hetzner_storage_box.cjs as the API/WebDAV wrapper. Do not handcraft
  5. For prompt/user testing, stop after plan or after helper payload
  6. For real user requests that need live Storage Box API or WebDAV reads, pass
  7. If a live http_request call returns 401 or 403, stop after that first
  8. Require explicit operator grant before creating boxes, changing settings,
  9. Never paste, print, or inspect HETZNER_API_TOKEN or Storage Box passwords.

What it can do on your machine

Read from SKILL.md and the folder at commit 8162701. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (JavaScript), which the agent can run.

    Shell commands in SKILL.md call:

    • node
    • python3

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names these keys or tokens, usually read from environment variables:

    • HETZNER_API_TOKEN
    • HETZNER_DNS_API_TOKEN

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Hetzner Storage Box loads about 2k tokens when it runs, and up to ~2.6k if it reads all its reference files. Until then it costs about 39 tokens; SKILL.md has 488 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~2k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~2.6k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Hetzner Storage Box

Use this skill for Storage Box inventory, lifecycle and snapshot management, plus WebDAV file reads and guarded uploads/archives.

Default Workflow

  1. Use Hetzner API reads (list-storage-boxes, get-storage-box) for inventory and metadata.
  2. Use WebDAV reads (list-files, download-file) for file inspection.
  3. Use plan before any management, file write, or public-link request.
  4. Treat hetzner_storage_box.cjs as the API/WebDAV wrapper. Do not handcraft Hetzner Storage Box API URLs, WebDAV URLs, JSON bodies, tiers, or secret refs from memory.
  5. For prompt/user testing, stop after plan or after helper payload generation. Do not call the built-in http_request tool.
  6. For real user requests that need live Storage Box API or WebDAV reads, pass the helper-emitted httpRequest object unchanged to http_request. The bearerSecretName or secretHeaders field is the secret reference; do not rewrite it, preflight it, inspect it, or ask the model for the secret.
  7. If a live http_request call returns 401 or 403, stop after that first failure. Do not retry, do not fan out to more endpoints or paths, and ask the operator to set or verify the relevant secret.
  8. Require explicit operator grant before creating boxes, changing settings, snapshots, uploads, archives, directory creation, public sharing, or deletes.
  9. Never paste, print, or inspect HETZNER_API_TOKEN or Storage Box passwords. The gateway injects API bearer tokens and WebDAV Basic auth server-side.

Secret Setup

API management calls use HETZNER_API_TOKEN. Set or update it in this order:

  1. Browser admin: open the active HybridClaw admin URL ending in /admin/secrets.
  2. Browser /chat or TUI fallback: /secret set HETZNER_API_TOKEN "<hetzner-console-api-token>".
  3. Local console fallback:
bash
hybridclaw secret set HETZNER_API_TOKEN "<hetzner-console-api-token>"

HETZNER_API_TOKEN is the Hetzner Console token for Cloud and Storage Box management APIs. DNS uses its own HETZNER_DNS_API_TOKEN because Hetzner DNS is served by a separate DNS API and Auth-API-Token header.

WebDAV file operations use a Basic-auth secret containing only the base64 encoded username:password payload. Set it in the same order:

  1. Browser admin: open the active HybridClaw admin URL ending in /admin/secrets.
  2. Browser /chat or TUI fallback: /secret set HETZNER_STORAGE_BOX_BASIC_AUTH "<base64-username-password>".
  3. Local console fallback:
bash
printf '%s' 'u00000:storage-box-password' | base64
hybridclaw secret set HETZNER_STORAGE_BOX_BASIC_AUTH "<base64-username-password>"

See references/operator-setup.md for operator setup, scope, and autonomy defaults.

Command Contract

bash
node skills/hetzner-storage-box/hetzner_storage_box.cjs --help

Build management API requests:

bash
node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json http-request list-storage-boxes
node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json http-request get-storage-box --box-id 123456
node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json http-request create-snapshot --box-id 123456 --description "pre-archive" --operator-grant

Build WebDAV file requests:

bash
node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json webdav-request list-files \
  --host u00000.your-storagebox.de --path /archives

node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json webdav-request upload-text \
  --host u00000.your-storagebox.de --path /archives/q4-invoices/manifest.txt \
  --body "Archived Q4 invoices" --operator-grant

node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json public-url \
  --host u00000.your-storagebox.de --path /archives/q4-invoices.zip

node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json share-public-link \
  --host u00000.your-storagebox.de --path /archives/q4-invoices.zip \
  --expires-at 2026-06-30 --operator-grant

Working Rules

  • Prefer read-only API tokens and read-only Storage Box subaccounts for file inspection.
  • Treat delete-storage-box, delete-snapshot, and delete-path as red-risk actions requiring exact target confirmation.
  • Use WebDAV over HTTPS for file operations unless the operator explicitly asks for SFTP/rsync outside this helper.
  • public-url only constructs the URL for a path that is already public. share-public-link is the guarded operator handoff for publishing a path and recording its intended expiration. Storage Box file access is credentialed by default, so do not present a path as public until the operator confirms the serving configuration.
  • Cost per assistant run is recorded by HybridClaw UsageTotals; helper output includes costMeasurement.system = "UsageTotals" for eval verification.

Eval Suite

bash
node skills/hetzner-storage-box/hetzner_storage_box.cjs --format json eval-scenarios

The fixture at evals/scenarios.json contains 10 scenarios covering inventory, snapshots, WebDAV list/download/upload/archive, public links, and deletes.

Validation

bash
python3 skills/skill-creator/scripts/quick_validate.py skills/hetzner-storage-box
