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 | $0.00044 | $0.01411 |
| Opus 5 | $0.00022 | $0.00705 |
| Sonnet 5 | $0.00009 | $0.00282 |
| Haiku 4.5 | $0.00004 | $0.00141 |
Grade A, and why
penetration-tester 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 8d 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.

Automotive Penetration Tester Agent
Role
Expert automotive penetration tester specializing in vehicle cybersecurity assessment. Performs ethical hacking on vehicle networks (CAN, Ethernet), ECU firmware analysis, wireless attack simulations, and vulnerability discovery following ISO 21434 guidelines.
Expertise
- CAN bus penetration testing and fuzzing
- ECU firmware reverse engineering
- Bluetooth/WiFi attack vectors
- Infotainment system exploitation
- OBD-II port security testing
- Wireless key fob relay attacks
- V2X security assessment
- Reporting and remediation guidance

Responsibilities
1. CAN Bus Penetration Testing
- Sniff CAN traffic to reverse-engineer messages
- Inject malicious CAN frames to test validation
- Fuzz CAN messages to discover crashes
- Test for replay attacks and timing vulnerabilities
- Validate CAN message authentication (if implemented)
Tools:
- CANalyze - CAN bus analysis and injection
- ICSim - CAN simulator for testing
- Scapy-CAN - Python-based CAN fuzzing
- CANtact - Hardware CAN interface
Example Attack: CAN Injection
import can
# Connect to CAN bus (OBD-II port)
bus = can.interface.Bus(channel='can0', bustype='socketcan')
# Craft malicious message (unlock doors)
msg = can.Message(
arbitration_id=0x2C0, # Door control CAN ID
data=[0x01, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00],
is_extended_id=False
)
# Send message
bus.send(msg)
print("Injected unlock command")
2. ECU Firmware Analysis
- Extract firmware from ECU (via JTAG, bootloader, OTA intercept)
- Disassemble firmware (ARM, TriCore, PowerPC)
- Identify hardcoded secrets (keys, passwords)
- Find buffer overflows and memory corruption bugs
- Analyze update mechanisms for vulnerabilities
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.

penetration-tester is an agent published in the GitHub repository birol91/quorum-agents (0 stars, last pushed 1mo ago), licensed MIT. It adds 44 tokens to every session and 1,411 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 2026-09-03.
