ssh

A guide to Secure Shell (SSH), a standard way to connect to another computer securely over a network. It covers SSH keys, connection settings, remote commands, and file transfers.

In plain words
What is it for?
Use it to manage SSH keys, connect to remote machines, run commands, copy files, forward ports, and inspect known hosts.
Why use it?
It helps avoid guessing the commands needed to connect to servers, diagnose connection problems, and move files between computers.

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.

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 E, and why

ssh scanned grade E with 2 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 3d 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.

Enumerates the file system for secretshighData exfiltration

Searching home directories for .env, .ssh, .aws or credential files is reconnaissance for credential theft.

- List keys: `ls -la ~/.ssh/`

Reaches for credential fileshighPrivilege escalation

SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.

- Show public key: `cat ~/.ssh/id_ed25519.pub`

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-add to add keys to the agent
  • Check ssh -v user@host for connection debugging
Changes

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 (169 stars, last pushed 3d ago), licensed MIT. It adds 8 tokens to every session and 273 once invoked, about $0.0000 per session on Opus 5. A static security scan graded it E with 2 findings (enumerates the file system for secrets, reaches for credential files). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
