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 5.1 | $0.00136 | $0.02941 |
| Opus 5 | $0.00068 | $0.01470 |
| Sonnet 5 | $0.00027 | $0.00588 |
| Haiku 4.5 | $0.00014 | $0.00294 |
Grade B, and why
hetzner-ssh scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 5d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Asks for rootmediumPrivilege escalation
A mod that escalates privileges can change anything on the machine, not only the project.
ssh <ssh_alias> 'sudo systemctl …' # sudo is passwordless on boxes hetzner-create built How it starts
The opening of the file, as written. The whole thing — 206 lines — stays where its author put it; the contents beside it link to each section on GitHub.
hetzner-ssh
Connect to a Hetzner VPS, prove it is the right one, and leave a live multiplexed
connection behind so every later command is cheap. Hosts are hardened: non-standard
sshd port, key-only auth, AllowUsers allowlist, Hetzner Cloud Firewall in front.
Invocation: /hetzner-ssh [server] — server is a key under servers in the roster.
Omit it to use the fleet.default entry.
Sibling skills: /hetzner-create (provision a new box) · /hetzner-delete (destroy one).
The roster schema is documented once, in hetzner-create/README.md.
Step 0 — Load the roster
cat ~/.config/hetzner/hetzner.json
($CLAUDE_SKILL_DIR is not set in Claude Code — use the literal path above.)
| Condition | Action |
|---|---|
| File missing | If you sync ~/.config/hetzner/ with a dotfiles manager, restore it there first (chezmoi apply ~/.config/hetzner/). Otherwise copy it from another machine, or run /hetzner-create to register a server. Stop. |
| Invalid JSON | Report the parse error and the offending line. Do not guess the contents. Stop. |
Requested server not in fleet.servers |
Print the available fleet.servers keys and stop. Never guess a neighbouring name. |
No arg and no fleet.default key |
Print the available keys and ask which one. Stop. |
Resolve the target: the user-supplied name, else .default. Fields missing from a
server entry fall back to defaults — so a lean entry is normal, not broken. Every
field below comes from the merged result; do not re-discover any of it.
| Field | Meaning |
|---|---|
ssh_alias |
Host alias in ~/.ssh/config.d/hetzner — the actual connect target |
expect_hostname |
What hostname must print, or you are on the wrong box |
ip, port, user |
Rendered into the ssh_config block |
key, key_fingerprint_prefix |
Which key, and how to spot it in the agent |
protected |
Read by /hetzner-delete. Irrelevant here |
hcloud_*, location, firewall |
Only used on the failure paths below |
notes |
Free text: panel ports, runbook paths, quirks |
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.
- 5d ago First seen · 206 lines · 136 tokens per session scan B 0674cacb4157
hetzner-ssh is a skill published in the GitHub repository IsaiaScope/ai (2 stars, last pushed yesterday), licensed MIT. It adds 136 tokens to every session and 2,941 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
