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.

SkillSpector: 3 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

Use environment variables or secrets managers. For docs, use placeholder paths (e.g., /path/to/config). Never load .env or token files in production code paths.

If file access is needed, use explicit, scoped paths. Avoid reading ~/.ssh, ~/.aws, or credential directories.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00008 | $0.00273 |
| Opus 5.5 | $0.00003 | $0.00109 |
| Sonnet 5.5 | $0.00002 | $0.00055 |
| Haiku 4.5 | $0.00001 | $0.00027 |
Grade A, and why
ssh 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 1mo 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.
What it actually says
SSH
Manage SSH keys and connections.
Key management
- List keys:
ls -la ~/.ssh/ - Generate key:
ssh-keygen -t ed25519 -C "comment" - Show public key:
cat ~/.ssh/id_ed25519.pub - Test connection:
ssh -T [email protected]
Config
- View:
cat ~/.ssh/config - List known hosts:
cat ~/.ssh/known_hosts | wc -l
Remote operations
- Connect:
ssh user@host - Run command:
ssh user@host "command" - Copy file to remote:
scp file.txt user@host:/path/ - Copy from remote:
scp user@host:/path/file.txt . - Port forward:
ssh -L 8080:localhost:80 user@host
Tips
- Use
ssh-addto add keys to the agent - Check
ssh -v user@hostfor connection debugging
What ships with it
3 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.
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.

ssh is a skill published in the GitHub repository gebruder/wirken (193 stars, last pushed 2d ago), licensed MIT. It adds 8 tokens to every session and 273 once invoked, about $0.0000 per session on Opus 5.5. 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 2026-08-30.
