使用说明 (SKILL.md)
System Monitor
Real-time system health monitoring for the gateway host. Zero external dependencies.
Usage
# Full status report (human-readable)
python3 scripts/monitor.py
# JSON output (for programmatic use)
python3 scripts/monitor.py --json
# Check alert thresholds
python3 scripts/monitor.py --check-alerts
# Top N processes
python3 scripts/monitor.py --top 10
What It Reports
| Metric | Source |
|---|---|
| CPU usage % | /proc/stat |
| RAM used/total/available | /proc/meminfo |
| Swap used/total | /proc/meminfo |
| Disk usage per mount | df -h |
| CPU temperature | /sys/class/thermal/thermal_zone0/temp |
| Uptime | /proc/uptime |
| Load average (1/5/15m) | /proc/loadavg |
| Top processes by CPU | ps aux |
Alert Thresholds
Default (configurable in SKILL.md or via code):
| Alert | Threshold |
|---|---|
| RAM | > 90% used |
| Swap | > 500MB used |
| CPU temp | > 75°C |
| Disk | > 90% full |
Security
- Read-only: Never writes, modifies, or executes anything beyond reading system stats
- No network access: Purely local
/proc,/sys,ps,df - No secrets: Does not access config files, tokens, or credentials
- Safe in groups: Output contains no sensitive paths, tokens, or user data
Automation
Use with cron for periodic health checks:
# Every 30 minutes via OpenClaw cron → alerts to Telegram
# Or via HEARTBEAT.md
安全使用建议
This skill appears to do what it says (local system health checks), but review these before installing:
- The script reads ~/.config/system-monitor/config.json (not declared in metadata). Inspect that file's contents/permissions if it exists.
- Process command lines are reported (sanitized for common token patterns), but the redaction is pattern-based and can miss secrets passed as positional arguments or stored in environment variables. If you run this on hosts with sensitive command-line arguments, consider restricting its use or limiting --top output.
- The SKILL.md claims 'no sensitive output' — treat that as optimistic. Expect mount points and trimmed commands in outputs.
- The script is local and read-only (no network), and there is no installer. If you need stronger guarantees, run it in a non-sensitive account or inspect/modify the code to suit your security policy.
If you want me to, I can suggest small code changes to harden redaction or to avoid reading the config file by default.
功能分析
Type: OpenClaw Skill
Name: lookupmark-system-monitor
Version: 1.3.0
The system-monitor skill is a standard utility for reporting host health metrics (CPU, RAM, disk, temperature) on Linux/ARM systems. The implementation in scripts/monitor.py is well-structured, uses safe subprocess calls with argument lists to prevent shell injection, and includes a proactive security feature (sanitize_cmdline) to redact potential secrets like tokens or passwords from the process list. No network activity, data exfiltration, or malicious instructions were identified.

能力评估
Purpose & Capability
The name/description match the code: it reads /proc, /sys, calls ps and df, and reports CPU, RAM, disk, temp, uptime and top processes. This behavior is expected for a system-monitor. Minor inconsistency: the SKILL.md header mentions vcgencmd but the script does not call it.
Instruction Scope
Runtime instructions are local and read-only; the script does not perform network calls or require external services. However the SKILL.md claims 'Safe in groups: Output contains no sensitive paths, tokens, or user data' — the script does include mount points and truncated process command lines which can contain sensitive info. The script attempts to sanitize common token/key patterns, but that redaction is pattern-based and not exhaustive.
Install Mechanism
No install spec (instruction-only with an included script). Nothing is downloaded or written by an installer.
Credentials
Metadata declared 'Required config paths: none', but the script reads a per-user config at ~/.config/system-monitor/config.json to load thresholds. No env vars or credentials are requested. Reading a user config folder is reasonable for thresholds, but the mismatch between metadata and actual config access should be noted.
Persistence & Privilege
always is false and the skill does not modify other skills or system settings. It only reads system state and a single per-user config file.
如何使用
