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

stealth-infra scanned grade B with 2 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 10d 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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

The opening of the file, as written. The whole thing — 335 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Stealth Infrastructure — Anti-Bot Evasion & Covert Operations

This skill covers the stealth tooling installed in the sandbox for evading anti-bot systems, rotating proxies, solving CAPTCHAs, and retrieving credentials from password managers. Use these tools when the engagement RoE specifies OPSEC level quiet or silent, or when targets deploy WAFs/anti-bot shields.

Available Libraries (Pre-Installed)

Library Purpose When to use
scrapling Adaptive scraping with Cloudflare Turnstile bypass, StealthyFetcher Primary choice for any anti-bot-protected target
curl_cffi libcurl with impersonated TLS fingerprints (Chrome/Firefox/Safari) When you need raw HTTP with real browser TLS
tls_client Go-based TLS fingerprint impersonation via Python Alternative to curl_cffi for different fingerprint profiles
cloudscraper Cloudflare v1/v2 challenge solver Legacy Cloudflare JS challenges
fake-useragent Realistic, rotating User-Agent strings Any HTTP request needing normal-looking UA
proxychains4 Force any CLI tool through a SOCKS/HTTP proxy chain Route nmap/curl/subfinder through Tor or proxy
tor Onion routing for IP anonymization When source IP must not be linkable to operator
keyring OS keyring access (GNOME Keyring, macOS Keychain, Windows Credential Vault) Retrieve stored credentials without hardcoding
python-socks SOCKS4/5 proxy support for asyncio Async HTTP through proxies
aiohttp-socks aiohttp + SOCKS proxy integration Async scraping through proxy chains

1. Scrapling — Primary Anti-Bot Bypass

Scrapling's StealthyFetcher uses a real Chromium instance with anti-fingerprinting patches. It bypasses Cloudflare Turnstile, Akamai, DataDome, and most JS challenges.

# Stealthy fetch — bypasses Cloudflare Turnstile and most anti-bot
timeout 60 python3 -u -c '
from scrapling.fetchers import StealthyFetcher

page = StealthyFetcher.fetch(
    "https://<TARGET>",
    headless=True,
    network_idle=True,
    disable_resources=True,  # skip images/fonts for speed
)
print(f"Status: {page.status}")
print(f"Title: {page.css(\"title::text\").get()}")
# Extract data

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.

stealth-infra is a skill published in the GitHub repository PurpleAILAB/Decepticon (5,471 stars, last pushed 10d ago), licensed Apache-2.0. It adds 29 tokens to every session and 2,729 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
