high confidenceThe skill's code and instructions match its stated purpose (website/SSL checks); the main issues are missing declared dependencies and some portability/operational notes, but nothing here appears malicious.
评估建议
This skill appears to do what it claims, but review and prepare before installing: 1) The package metadata omits required binaries — ensure your environment has curl, openssl, python3 (and standard Unix utilities like mktemp, grep, sed). 2) The scripts use GNU-style date parsing; macOS (BSD date) may fail — test on your platform. 3) Alerts are referenced but no delivery method (webhook/email/Slack) is implemented — you will need to add an alerting integration if you want notifications. 4) The sc...详细分析 ▾
ℹ 用途与能力
The name/description align with the provided scripts: check_site.sh (HTTP/timing) and check_ssl.sh (openssl certificate checks). However the registry metadata lists no required binaries while the scripts rely on curl, openssl, python3 (for JSON parsing), mktemp, and typical GNU date features — this mismatch is an omission that should be fixed before use.
ℹ 指令范围
SKILL.md stays within scope: it runs the included scripts, stores a config/history in the user's home, and recommends cron for scheduling. It references 'send alerts' but does not implement or describe external alert endpoints or notification mechanisms (no webhook/email provider configured), so alert delivery is undefined. The instructions do not ask for unrelated files, secrets, or other system credentials.
✓ 安装机制
There is no install spec (instruction-only) and the scripts are included in the package; nothing is downloaded at install time. This minimizes install-time risk.
✓ 凭证需求
The skill requests no environment variables or credentials and the scripts do not attempt to read secrets. They only perform network connections to the target sites and write config/history under the user's home directory.
✓ 持久化与权限
always:false and no cross-skill/system-wide modifications. The skill stores config/history in ~/.openclaw/workspace by default — normal for a monitoring tool and not an elevated privilege.

技能文档
Monitor one or more websites for health issues. Detect downtime, expiring SSL certs, slow responses, and content changes — then report or alert.
Quick Check (Single URL)
When user asks to check a single URL right now:
- Run
scripts/check_site.sh - Parse the JSON output
- Present a formatted health report
Monitored Sites Config
For ongoing monitoring, maintain a config at user's chosen location (default: ~/.openclaw/workspace/site-monitor.json):
{
"sites": [
{
"url": "https://example.com",
"name": "Main Site",
"checks": ["uptime", "ssl", "response_time", "content"],
"alert_threshold_ms": 3000,
"ssl_warn_days": 14,
"content_selector": "title"
}
],
"defaults": {
"checks": ["uptime", "ssl", "response_time"],
"alert_threshold_ms": 5000,
"ssl_warn_days": 30
}
}
Health Checks
1. Uptime
- HTTP GET to URL
- Pass: 2xx/3xx status
- Warning: 4xx status
- Fail: 5xx, connection refused, timeout (>10s)
2. SSL Certificate
- Run
scripts/check_ssl.sh - Pass: Valid, >30 days to expiry
- Warning: <30 days to expiry (configurable)
- Fail: Expired, self-signed, or missing
3. Response Time
- Measure TTFB + transfer via
scripts/check_site.sh - Pass: Under threshold (default 5000ms)
- Warning: 1-2x threshold
- Fail: >2x threshold or timeout
4. Content Changes (Planned)
- Fetch page, extract text, hash it
- Compare against stored hash
- Report if content changed since last check
- Note: This feature is planned for v1.1
Reports
Single Site
## 🟢 example.com — Healthy
Check Status Detail Uptime ✅ UP 200 OK (143ms) SSL ✅ OK Expires in 87 days Response Time ✅ OK 342ms (threshold: 5000ms) Content — Same No changes detected
Multi-Site Summary
## Site Health — 2026-03-26
Site Status Issues example.com 🟢 OK — api.foo.io 🟡 WARN SSL: 12 days shop.bar 🔴 DOWN 503 error
Alerts
Alert when: site DOWN, SSL within warning window, response >2x threshold, 2+ consecutive failures.Format: ⚠️ [site] — [issue]. [detail]. Checked at [time].
Scheduled Monitoring
Suggest cron job for recurring checks (30-60 min interval for production). Store last 100 results per site in ~/.openclaw/workspace/.site-monitor-history.json.
Scripts
scripts/check_site.sh— HTTP health check, outputs JSON (status, timing, headers)scripts/check_ssl.sh— SSL cert check, outputs JSON (issuer, expiry, days remaining)
