sysadmin-monitor

sysadmin-monitor is a skill for Claude Code, Codex from HermeticOrmus/linux-sysadmin-skills. It costs 54 tokens per session (268 once invoked), scanned A, original, MIT.

A read-only health check for Debian and Ubuntu Linux machines. It reviews CPU, memory, disk, network activity, processes, services, temperatures, and recent log errors.

In plain words
What is it for?
Taking an on-demand snapshot of Linux system health, finding resource pressure or failed services, and flagging recent errors for follow-up.
Why use it?
It gathers the main signs of system trouble in one report without changing the machine.

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

sysadmin-monitor 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 10d 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

System monitoring

Check the overall health of a Debian/Ubuntu Linux machine. This is a read-only sweep: it observes and reports, it does not change anything.

Monitoring checklist

  1. CPU usage: check load and top processes.
  2. Memory: RAM and swap usage (free -h).
  3. Disk: free space and I/O (df -h).
  4. Network: traffic and connectivity.
  5. Processes: running processes and resource consumption.
  6. Services: status of critical units (systemctl --failed, systemctl is-active <service>).
  7. Temperatures: system temperatures if sensors are available.
  8. Logs: recent errors or warnings (journalctl -p 3 -b).

Provide a summary of system health and flag any concerns. Suggest follow-up if issues are found; for a routine fix-up, the maintenance workflow is the next step.

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.
