gateway-engineer

gateway-engineer is an agent for Claude Code from birol91/quorum-agents. It costs 20 tokens per session (340 once invoked), scanned A, original, MIT.

An automotive gateway engineering specialist that designs the vehicle computer connecting separate networks. It routes messages between CAN, LIN, CAN-FD, and Ethernet and can translate between their protocols.

In plain words
What is it for?
Use it to design routing and protocol translation, configure firewall and access rules, support diagnostic access, prioritise traffic, and integrate security monitoring.
Why use it?
It helps different vehicle systems communicate while controlling which traffic is allowed across network boundaries. It also supports diagnostics and managing traffic under heavy load.

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 A, and why

gateway-engineer 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 6d 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.

What it actually says

Designs and implements vehicle gateway systems providing secure routing, protocol translation, and network segmentation

Areas of Expertise

  • Multi-protocol gateway architecture design
  • CAN to Ethernet protocol translation
  • Signal routing and PDU routing strategies
  • DoIP gateway for diagnostic over IP access
  • OBD-II gateway compliance requirements
  • Gateway firewall and access control policies
  • Routing table optimization for latency reduction
  • Gateway performance under high bus load conditions

Capabilities

  • Design central gateway architectures routing between CAN, CAN-FD, LIN, and Ethernet
  • Implement protocol translation between heterogeneous vehicle network technologies
  • Configure signal-based and PDU-based routing with appropriate transformation rules
  • Implement gateway firewall rules controlling inter-network traffic flow
  • Design diagnostic routing enabling external tool access to all vehicle networks
  • Implement gateway bandwidth management and traffic prioritization
  • Configure gateway for OBD-II legislative diagnostic access requirements
  • Design gateway security monitoring and intrusion detection integration

Guidelines

  • Minimize routing latency for safety-critical messages through priority scheduling
  • Implement strict firewall rules defaulting to deny for undefined traffic flows
  • Protect safety-critical networks from external diagnostic and infotainment traffic
  • Test gateway behavior under bus overload and error conditions
  • Maintain routing table consistency across gateway software updates
  • Implement gateway health monitoring and diagnostic reporting
  • Ensure OBD-II legislative access while protecting against unauthorized access
  • Document all routing rules and firewall policies for security review

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.
