cf-crawl

cf-crawl is a skill for Claude Code from YuDefine/nuxt-supabase-starter. It costs 88 tokens per session (3,060 once invoked), scanned A, original, MIT.

A workflow that crawls an entire website or documentation site and saves the captured content as Markdown files. Website crawling means collecting pages in bulk rather than fetching one page at a time.

In plain words
What is it for?
It is for importing documentation, crawling websites in batches, and extracting web content when the required Cloudflare access credentials are available.
Why use it?
It provides a local copy of site content for later use and makes large documentation or knowledge bases easier to process.

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

cf-crawl scanned grade A 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 today.

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.

How it starts

The opening of the file, as written. The whole thing — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Cloudflare Website Crawler

You are a web crawling assistant that uses Cloudflare's Browser Rendering /crawl REST API to crawl websites and save their content as markdown files for local use.

Prerequisites

The user must have:

  1. A Cloudflare account with Browser Rendering enabled
  2. CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN available (see below)

Workflow

When the user asks to crawl a website, follow this exact workflow:

Step 1: Load Credentials

Look for CLOUDFLARE_ACCOUNT_ID and CLOUDFLARE_API_TOKEN in this order:

  1. Current environment variables - Check if already exported in the shell
  2. Project .env file - Read .env in the current working directory and extract the values
  3. Project .env.local file - Read .env.local in the current working directory
  4. Home directory .env - Read ~/.env as a last resort

To load from a .env file, parse it line by line looking for CLOUDFLARE_ACCOUNT_ID= and CLOUDFLARE_API_TOKEN= entries. Use this bash approach:

# Load from .env if vars are not already set
if [ -z "$CLOUDFLARE_ACCOUNT_ID" ] || [ -z "$CLOUDFLARE_API_TOKEN" ]; then
  for envfile in .env .env.local "$HOME/.env"; do
    if [ -f "$envfile" ]; then
      eval "$(grep -E '^CLOUDFLARE_(ACCOUNT_ID|API_TOKEN)=' "$envfile" | sed 's/^/export /')"
    fi
  done
fi

If credentials are still missing after checking all sources, tell the user to add them to their project .env file:

CLOUDFLARE_ACCOUNT_ID=your-account-id
CLOUDFLARE_API_TOKEN=your-api-token

The API token needs "Browser Rendering - Edit" permission. Create one at Cloudflare Dashboard > API Tokens.

Step 2: Validate Credentials

Verify both variables are set and non-empty before proceeding.

Step 3: Initiate Crawl

Send a POST request to start the crawl job. Choose parameters based on user needs:

curl -s -X POST "https://api.cloudflare.com/client/v4/accounts/${CLOUDFLARE_ACCOUNT_ID}/browser-rendering/crawl" \
  -H "Authorization: Bearer ${CLOUDFLARE_API_TOKEN}" \
  -H "Content-Type: application/json" \
  -d '{
    "url": "<TARGET_URL>",
    "limit": <NUMBER_OF_PAGES>,
    "formats": ["markdown"],
    "options": {
      "excludePatterns": ["**/changelog/**", "**/api-reference/**"]
    }
  }'

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.

cf-crawl is a skill published in the GitHub repository YuDefine/nuxt-supabase-starter (45 stars, last pushed today), licensed MIT. It adds 88 tokens to every session and 3,060 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
