remote-systems-administration

remote-systems-administration is a skill for Claude Code, Codex from magnus919/agent-skills. It costs 102 tokens per session (2,039 once invoked), scanned B, original, MIT.

A guide for safely administering remote Unix-like computers, including Linux, FreeBSD, NetBSD, OpenBSD, and macOS. It covers connecting to one machine or managing many machines together.

In plain words
What is it for?
Use it for SSH access, Ansible automation, system diagnostics, service management, software updates, configuration changes, and firewall or network changes.
Why use it?
It helps avoid making unsafe changes to remote systems, especially changes that could cut off access or affect production services. It emphasizes checking the system first, planning recovery, and verifying each change.

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 B, and why

remote-systems-administration 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 9d 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.

A mod that escalates privileges can change anything on the machine, not only the project.

2. **Treating an SSH connection as proof of authority.** Connection success does not confirm sudo policy, host identity, or authorization for the change.

Remote Systems Administration

Use this as an operating decision layer, not a bag of remote commands. Unix-like systems share a vocabulary but not an implementation. Identify the target's platform and active control plane before choosing a command.

Operating contract

  1. Discover before changing. Record target identity, production status, OS and release, service manager, package manager, firewall, access route, privilege path, and current state. Do not infer them from hostname, memory, or inventory labels.
  2. Use the smallest valid control plane. Native SSH for a bounded one-host task; Ansible for repeatable desired state across a fleet; Paramiko only when a Python program genuinely needs SSH protocol control that the first two cannot provide.
  3. Protect access first. Before changing SSH, routing, DNS, a firewall, privilege escalation, or a network interface, establish a tested rollback and a second recovery path. Keep the current session alive until the new path works.
  4. Preview, constrain, verify. Limit the target set; use native validation, dry-run, diff, or a canary when available; then verify the affected service and its user-visible boundary. A zero exit code proves only that command ran.
  5. Report evidence, not a story. Preserve bounded per-host results: target, command category, before/after evidence, failures, rollback state, and the remaining uncertainty. Never paste secrets, keys, full configuration files, or unbounded logs into the response.

Run the shared classification probe in references/portable-operations.md, then load the matching OS/family overlay and run its command preflight. Select a mutation command only after the required preflight and safety gate.

Read-only discovery handoff

Use this compact format after a preflight. Fill a field only from observed evidence; otherwise write unknown or not supplied.

  • Observed platform and control planes:
  • Bounded evidence:
  • Unknown or blocked:
  • Next safe action:

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.
