At a glance

Monitor system health: CPU, memory, disk, network, processes, services, and logs.

  • Works in 5 steps: Check health first — system_health() for… → Check memory — recall past similar… → Drill into specifics — processes, disk,… → …
  • Tasks that involve Root cause analysis
  • SKILL.md covers Quick Health Check, Process Monitoring, Disk Usage and Diagnosis Workflow, plus 1 more section
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

System Monitor is an agent skill from bolivian-peru/os-moda. Monitor system health: CPU, memory, disk, network, processes, services, and logs. Present data naturally. Correlate issues across subsystems. Alert on thresholds. Diagnose root causes.

Its SKILL.md is about 470 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in Development, covering Root cause analysis. The repository describes itself as: An operating system built for AI agents — talk to your NixOS server instead of SSH-ing in. Typed, audited tool access with atomic rollback on every change. Research-grade; run it… The licence is Apache-2.0.

When your agent uses it

  • Tasks that involve Root cause analysis

Example prompts

  • “/system-monitor”

Requirements

  • Docker

Workflow steps

5 steps, taken from the first numbered list in SKILL.md.

  1. Check health first — system_health() for the overview
  2. Check memory — recall past similar issues: memory_recall({ query: "similar problem description" })
  3. Drill into specifics — processes, disk, network as needed
  4. Correlate — "your disk is full because Docker images take 40GB"
  5. Store the diagnosis — memory_store({ summary: "...", detail: "...", category: "diagnosis" })

What it can do on your machine

Read from SKILL.md and the folder at commit b8e418f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

System Monitor loads about 473 tokens when it runs. Until then it costs about 50 tokens; SKILL.md has 165 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~50
When it runs · the whole SKILL.md, loaded when a task matches
~473

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

System Monitor Skill

You can monitor every aspect of the system in real time.

Quick Health Check

system_health()

Returns CPU usage per core, memory (total/used/available), swap, disk usage per mount, load average, and uptime.

Process Monitoring

List processes by resource usage
system_query({ query: "processes", args: { sort: "cpu", limit: 20 } })
system_query({ query: "processes", args: { sort: "memory", limit: 20 } })
Investigate a specific process
system_query({ query: "processes", args: { name: "firefox" } })

Disk Usage

system_query({ query: "disk" })

Returns per-mount: filesystem type, total/used/available space, usage percentage.

Diagnosis Workflow

When the user reports a problem:

  1. Check health first — system_health() for the overview
  2. Check memory — recall past similar issues: memory_recall({ query: "similar problem description" })
  3. Drill into specifics — processes, disk, network as needed
  4. Correlate — "your disk is full because Docker images take 40GB"
  5. Store the diagnosis — memory_store({ summary: "...", detail: "...", category: "diagnosis" })

Always diagnose before suggesting fixes. Explain what you found. Store diagnoses for future reference — next time the same issue occurs, you'll recall it instantly.

Thresholds

Flag these to the user proactively:

  • CPU sustained >90% for >5 minutes
  • Memory usage >85%
  • Swap usage >50%
  • Any disk mount >90% full
  • Load average > 2x number of cores
