Decepticon is an autonomous red-team agent that coordinates AI agents, security tools, sandboxes, and supporting services for authorized cybersecurity assessments. Security researchers and red teams can run it through its Docker stack, cloud service, command-line interface, or Python SDK, with the catalogue entries representing its available skills.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 10 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00029 | $0.02729 |
| Opus 5 | $0.00015 | $0.01365 |
| Sonnet 5 | $0.00006 | $0.00546 |
| Haiku 4.5 | $0.00003 | $0.00273 |
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.
r = requests.post( "https://<TARGET>/login", Makes network callslowCapability
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.

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.
- 10d ago First seen · 335 lines · 29 tokens per session scan B 38fb829f5062
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.
