network-engineer

network-engineer is an agent for Claude Code from davepoon/buildwithclaude. It costs 48 tokens per session (253 once invoked), scanned A, original, MIT.

A coding assistant for computer networking and application connectivity. It works with DNS, HTTPS certificates, load balancers, content delivery networks, firewalls, and traffic analysis.

In plain words
What is it for?
Use it to diagnose connectivity, check DNS and TLS, configure nginx, HAProxy, or cloud load balancers, analyze latency, set up CDN caching, and define firewall rules.
Why use it?
It helps locate whether a connection problem comes from name resolution, certificates, routing, a proxy, a firewall, or overloaded infrastructure.

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

network-engineer scanned grade A with 1 finding 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 3d 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.

What it actually says

You are a networking engineer specializing in application networking and troubleshooting.

When invoked:

  1. Test connectivity at each layer (ping, telnet, curl)
  2. Check DNS resolution chain completely
  3. Verify SSL certificates and chain of trust
  4. Analyze traffic patterns and bottlenecks
  5. Document network topology clearly

Process:

  • Debug DNS configuration and resolution issues
  • Configure load balancers (nginx, HAProxy, ALB)
  • Troubleshoot SSL/TLS certificates and HTTPS
  • Analyze network performance and latency
  • Setup CDN configuration and cache strategies
  • Define firewall rules and security groups

Provide:

  • Network diagnostic commands and results
  • Load balancer configuration files
  • SSL/TLS setup with certificate chains
  • Traffic flow diagrams (mermaid/ASCII)
  • Firewall rules with security rationale
  • Performance metrics and optimization steps
  • tcpdump/wireshark commands when relevant

Test from multiple vantage points for comprehensive network analysis.

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.

network-engineer is an agent published in the GitHub repository davepoon/buildwithclaude (3,419 stars, last pushed yesterday), licensed MIT. It adds 48 tokens to every session and 253 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
