Smart Web Monitor (智能网页监控)#

Watch any web page for changes — with AI-powered understanding. Instead of rigid keyword matching, describe what you're looking for in natural language and let the agent decide.

Why "Smart"?#

普通监控Smart Web Monitor关键词匹配： risk manager自然语言： "是否有风控岗位？排除实习"静态正则： risk.{0,20}managerAgent 理解上下文语义匹配即通知匹配后 Agent 可以总结、分析、过滤一次判断Agent 持续推理，理解页面结构变化

Quick Start#

Create a Monitor#

bash

# Simple: keyword match
python3 scripts/monitor.py create \
  --name "hk-risk-jobs" \
  --url "https://careers.example.com/risk" \
  --match-type keyword \
  --match-value "risk manager,hong kong,compliance"

# Smart: LLM match (agent evaluates with natural language understanding)
python3 scripts/monitor.py create \
  --name "hk-fintech-news" \
  --url "https://36kr.com" \
  --match-type llm \
  --match-value "是否有香港金融科技、虚拟银行相关新闻？排除广告。"

Run (keyword/regex/css/jsonpath)#

bash

python3 scripts/monitor.py run --event hk-risk-jobs
# → auto-matches, auto-pauses on match

Fetch for LLM (extract text only)#

bash

python3 scripts/monitor.py fetch --event hk-fintech-news
# → outputs JSON with page text for LLM agent to evaluate

After Match — Pause & Resume#

bash

python3 scripts/monitor.py resume --event xxx   # 继续
python3 scripts/monitor.py pause --event xxx    # 暂停
python3 scripts/monitor.py disable --event xxx  # 停用
python3 scripts/monitor.py enable --event xxx   # 启用

🤖 LLM Match (Smart Matching — 核心功能)#

This is what makes the monitor "smart". Instead of rigid pattern matching, the agent reads the page and thinks.

How it works:

1. monitor.py fetch — fetches page, extracts clean text → outputs JSON
2. Cron agent — reads the text, evaluates using its own LLM reasoning
3. Agent decides: does this match the condition?
4. If matched → notifies you with a summary → auto-pauses (won't spam)
5. If not matched → silently skips

This enables natural language conditions that would be impossible with regex:

• "是否有新的职位空缺？排除已见过的"
• "页面上有没有提到 Series B 或以上的融资？"
• "是否出现了与 AI 安全相关的文章？排除广告和推广内容"

State Machine#

text

active ──(match found)──→ paused ──(resume)──→ active
   │                                            ↑

Monitor Config Format#

json

{
  "name": "hk-risk-jobs",
  "description": "Hong Kong risk management jobs",
  "urls": [{"url": "https://careers.example.com/risk", "label": "Example"}],
  "match": {
    "type": "llm",
    "value": "是否有香港风控或合规岗位？排除实习。"
  },
  "interval": 7200,
  "state": "active",
  "enabled": true
}

Cron Integration#

For keyword/regex/css/jsonpath monitors:#

bash

openclaw cron add \
  --name "Monitor: hk-risk-jobs" \
  --cron "0 */2 * * *" \
  --tz "Asia/Hong_Kong" \
  --session isolated \
  --message "Run monitor: cd /home/node/.openclaw/workspace/skills/web-monitor && python3 scripts/monitor.py run --event hk-risk-jobs" \
  --announce --channel discord --to "user:YOUR_ID" --light-context

For LLM monitors:#

bash

openclaw cron add \
  --name "Monitor: hk-fintech-news" \
  --cron "0 */3 * * *" \
  --tz "Asia/Hong_Kong" \
  --session isolated \
  --message 'You are a web monitor agent. Run: cd /home/node/.openclaw/workspace/skills/web-monitor && python3 scripts/monitor.py fetch --event hk-fintech-news. Read the output JSON. For each URL, evaluate if the page content matches the condition: "是否有香港金融科技相关新闻？排除广告。" If matched: output a brief summary of what matched. If not matched: say "no match". If matched, also run: python3 scripts/monitor.py pause --event hk-fintech-news' \
  --announce --channel discord --to "user:YOUR_ID" --light-context
