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
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

SkillSpector: 43 findings, up to critical
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 | $0.00066 | $0.05636 |
| Opus 5 | $0.00033 | $0.02818 |
| Sonnet 5 | $0.00013 | $0.01127 |
| Haiku 4.5 | $0.00007 | $0.00564 |
Grade D, and why
lfi scanned grade D with 3 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 9d 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.
curl -s 'http://<TARGET>/page?file=php://input' -d '<?php system("cat /.env"); ?>' Reaches for credential fileshighPrivilege escalation
SSH keys, cloud credentials, git-credentials, .npmrc, /etc/shadow: reading these is how a config file becomes a credential leak.
for f in /etc/passwd /etc/shadow /root/.ssh/id_rsa \ Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.

How it starts
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.
Path Traversal / Local File Inclusion (LFI)
Exploits insufficient path validation to read arbitrary files or include them for execution. Often targets file download/display endpoints, template inclusion, or static resource handlers.
Precondition — Use Recon Handoff First
If the recon handoff (recon/SUMMARY.md RECON_HANDOFF: line) names a
specific file/path parameter (e.g. /<endpoint>?file=, /<endpoint>?path=,
/<endpoint>?name=), START with the parameter named in the handoff. Do
NOT run gobuster/ffuf/dirb against the host before testing the
handoff parameter — recon already enumerated the surface. The Detection
block below is for engagements where NO recon handoff exists.
The first 3 commands you run in this skill MUST target the recon-named parameter with these payload classes (one per command):
- plain traversal —
../../../etc/passwd - stripped-traversal bypass —
....//....//....//etc/passwd - PHP wrapper —
php://filter/convert.base64-encode/resource=<file>
Only if all three return baseline-matched response (per the
§"Response Body Verification" check) should you consider broader endpoint
discovery — and that discovery belongs in exploit/PIVOT.md first,
documenting (a) what payload classes you tried against the handoff
parameter, (b) why the handoff vector is exhausted, (c) the new surface
you are moving to.

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.
- 9d ago First seen · 335 lines · 66 tokens per session scan D 4d87b57940fb
lfi is a skill published in the GitHub repository PurpleAILAB/Decepticon (5,491 stars, last pushed 13d ago), licensed Apache-2.0. It adds 66 tokens to every session and 5,636 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it D with 3 findings (sends data to an external url, reaches for credential files, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
