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.

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 | $0.00048 | $0.05109 |
| Opus 5 | $0.00024 | $0.02554 |
| Sonnet 5 | $0.00010 | $0.01022 |
| Haiku 4.5 | $0.00005 | $0.00511 |
Grade A, and why
sidewinder-rattlesnake 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 7d 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.
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.

SideWinder (Rattlesnake, T-APT-04, Razor Tiger) — Adversary Emulation Profile
SideWinder (MITRE ATT&CK G0121) is a suspected Indian state-sponsored cyber-espionage group active since at least 2012. It is one of the most prolific APT actors in the South Asian threat landscape, with over 1,000 documented attacks against government organizations in the Asia-Pacific region since April 2020 alone. SideWinder is characterized by rapid malware iteration (generating modified variants in under five hours after detection), heavy reliance on spearphishing with government/military-themed lures, exploitation of the aged CVE-2017-11882 Equation Editor vulnerability, multi-stage JavaScript and .NET infection chains, and custom post-exploitation tooling — most notably the modular StealerBot implant discovered in 2024. The group maintains a massive infrastructure footprint (400+ live domains with hundreds of sub-domains mimicking legitimate government sites) and has progressively expanded from its traditional Pakistan-centric targeting to maritime, logistics, nuclear, and diplomatic entities across the Middle East, Africa, and Southeast Asia.
Attribution & motivation
- Sponsor / nation: India (suspected). Multiple threat intelligence vendors (Kaspersky GReAT, Group-IB, AT&T Alien Labs, Trend Micro, Zscaler ThreatLabz) assess SideWinder as an Indian state-sponsored group based on targeting patterns, infrastructure analysis, and victimology aligned with Indian strategic interests.
- Motivation: Primarily strategic intelligence collection (espionage) — military, government, and diplomatic intelligence from neighboring adversary states (especially Pakistan). Secondary interests include monitoring political developments in Nepal, Bangladesh, Sri Lanka, Afghanistan, and China, and — since 2024 — collecting intelligence on maritime logistics, energy, and nuclear power infrastructure.
- Attribution confidence: Moderate-High. No formal government attribution exists, but consistent and convergent vendor reporting (Kaspersky, Group-IB, Trend Micro, AT&T Alien Labs, Zscaler, Cyble) over a decade, combined with Pakistan government espionage advisories (NTISB 2019), support the Indian nexus assessment.
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.

sidewinder-rattlesnake is a skill published in the GitHub repository PurpleAILAB/Decepticon (5,451 stars, last pushed 7d ago), licensed Apache-2.0. It adds 48 tokens to every session and 5,109 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
