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 B, and why

crawl-websites-at-scale scanned grade B with 1 finding 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.

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.

  • Run scheduled or large-scale scraping pipelines
  • Need built-in support for request throttling, retries, and middlewares

Required tools / APIs

  • No external API required
  • Python 3.8+ required
  • Scrapy: Web crawling and scraping framework

Install options:

# pip
pip install scrapy

# Ubuntu/Debian
sudo apt-get install -y python3-pip && pip install scrapy

# macOS
brew install python && pip install scrapy

# Verify installation
scrapy version

Skills

basic_usage

Create and run a simple Scrapy spider to scrape a single page.

# Create a new Scrapy project
scrapy startproject myproject
cd myproject

# Generate a spider
scrapy genspider quotes quotes.toscrape.com

# Run the spider and save to JSON
scrapy crawl quotes -o output.json

# Run the spider and save to CSV
scrapy crawl quotes -o output.csv

Python spider (quotes.py):

import scrapy

class QuotesSpider(scrapy.Spider):
    name = "quotes"
    start_urls = ["https://quotes.toscrape.com"]

    def parse(self, response):
        for quote in response.css("div.quote"):
            yield {
                "text": quote.css("span.text::text").get(),
                "author": quote.css("small.author::text").get(),
                "tags": quote.css("a.tag::text").getall(),
            }

        # Follow pagination links
        next_page = response.css("li.next a::attr(href)").get()
        if next_page:
            yield response.follow(next_page, self.parse)

robust_usage

Production-oriented spider with settings, item pipelines, and error handling.

# Run with custom settings (rate limiting, retries)
scrapy crawl quotes \
  -s DOWNLOAD_DELAY=1 \
  -s AUTOTHROTTLE_ENABLED=True \
  -s RETRY_TIMES=3 \
  -o output.json

# Run from a script (no project required)
scrapy runspider spider.py -o output.json

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.
