ssh-config-tips

ssh-config-tips is a skill for Claude Code, Codex from rtwsvj/skill-switch. It costs 30 tokens per session (114 once invoked), scanned A, original, MIT.

Guidance for organizing SSH settings, which control connections to remote computers, in the ~/.ssh/config file using named host aliases and key options.

In plain words
What is it for?
Use it to create or edit host aliases such as work, set host names and users, and choose which identity SSH should use.
Why use it?
It makes connections to multiple SSH hosts easier to manage while keeping private key files local and unread.

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

ssh-config-tips 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 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.

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 Config Tips

Organize ~/.ssh/config with per-host blocks:

Host work
  HostName git.work.example
  User git
  IdentitiesOnly yes

This skill only edits the config file's host aliases. It never reads or transmits key material; generate keys yourself with ssh-keygen and keep private keys local.

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.
