Ubuntu Inspector

专门用于 Ubuntu 系统的健康巡检工具，监控硬件状态、磁盘占用以及网络连通性。

Security Scan

The skill's code and instructions match its stated purpose (Ubuntu system health checks); nothing in the files indicates misdirection or unexpected credential requests, though a few minor operational and privacy notes exist.

Purpose & Capability

Name/description, SKILL.md and main.py align: the code collects CPU, memory, disk and network status which is coherent with an Ubuntu inspector. Minor mismatch: main.py references a services list but does not implement service checks; psutil is used but not declared in metadata (functional, not malicious).

Instruction Scope

SKILL.md instructs only to produce a system report. main.py stays within that scope, but it exposes hostname and platform information (OS fingerprinting) and makes an outbound TCP connection to 8.8.8.8:53 to test connectivity — both are expected for a health check but can leak identifying network/host info.

Install Mechanism

There is no install spec (no code will be downloaded during install), which minimizes install-time risk. However, main.py imports psutil (and expects a Python runtime); that dependency is not declared and may cause runtime failures if psutil is not present in the agent environment.

Credentials

The skill requests no environment variables, credentials, or config paths — consistent with its stated purpose. It does not attempt to read files or access unrelated secrets.

Persistence & Privilege

Flags show no always:true and no install-time persistence. The code does not modify agent/system config or persist credentials. Agent autonomous invocation is allowed by default but not excessive here.

Assessment

This skill appears to do only local health checks and is coherent with its description, but consider: (1) it attempts an outbound connection to 8.8.8.8:53 to test network — ensure outbound network probes are acceptable in your environment; (2) it reports hostname and OS details which could be sensitive if you share reports externally; (3) psutil is imported but not declared—the runtime may need psutil installed for the skill to work; and (4) service checks are commented as potentially requiring sudo, so some checks may be limited in restricted environments.

Ubuntu System Health Inspector

这是一个功能强大的 Ubuntu 系统巡检技能，旨在为 AI Agent 提供实时的宿主机硬件和软件状态监控能力。

主要功能特点

1. CPU 负载监控：实时获取系统 CPU 使用率及负载情况。
2. 内存分析：统计可用内存、已用内存以及交换分区状态。
3. 磁盘空间检查：扫描根目录及挂载点的剩余空间，预防磁盘爆满。
4. 网络连通性测试：检查核心网关和外部 DNS 的连通性。

使用场景

当用户询问“系统现在卡不卡？”、“磁盘还有多少空间？”或者“网络通不通？”时，Agent 会自动调用该技能。

工具列表

get_system_report

该工具无需参数，执行后会返回一段包含上述所有指标的 JSON 格式文本报告。Agent 会根据报告内容生成友好的巡检建议。
