Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

web-scraper scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 12d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/check.py, scripts/scraper_cli.py, scripts/scraper_enhanced.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

# 使用会话
python3 scripts/scraper_cli.py --url "https://example.com" --session "my_session"

# XPath 提取
python3 scripts/scraper_cli.py --url "https://example.com" --xpath '{"title": "//h1/text()"}'

# 正则提取
python3 scripts/scraper_cli.py --url "https://example.com" --regex '{"emails": "[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}"}'

# 并发抓取
python3 scripts/scraper_cli.py --urls "https://example1.com" "https://example2.com" --concurrent

# 指定输出文件
python3 scripts/scraper_cli.py --url "https://example.com" --output "result.json"

# 会话管理
python3 scripts/scraper_cli.py --list-sessions
python3 scripts/scraper_cli.py --clear-session --session "old_session"

Python API

from scraper_enhanced import scrape_enhanced, SessionManager, DataExtractor

# 简单抓取
result = scrape_enhanced(
    url="https://example.com",
    selectors={"title": "h1", "content": ".article"},
    session_name="my_session"
)

# 使用会话管理器
session = SessionManager("test_session")
fetch_result = session.fetch("https://example.com")

# 使用数据提取器
extractor = DataExtractor(fetch_result["content"])
css_data = extractor.extract_css({"title": "h1"})
xpath_data = extractor.extract_xpath({"title": "//h1/text()"})

技术实现

基于 requests + BeautifulSoup4 + lxml 实现,提供完整的抓取解决方案。

Files

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
