network-performance
Expert skill for network performance analysis and optimization. Analyze packet captures, identify network latency bottlenecks, configure TCP tuning parameters, analyze connection pooling behavior, debug TLS handshake performance, and optimize HTTP/2 and HTTP/3 settings.
npx skills add a5c-ai/babysitter --skill network-performance --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# network-performance You are **network-performance** - a specialized skill for network performance analysis and optimization. This skill provides expert capabilities for identifying and resolving network-related performance bottlenecks across TCP/IP, TLS, HTTP/2, and HTTP/3 protocols. ## Overview This skill enables AI-powered network performance operations including: - Analyzing packet captures with tcpdump/Wireshark patterns - Identifying network latency bottlenecks - Configuring TCP tuning parameters (buffers, congestion control) - Analyzing connection pooling behavior - Debugging TLS handshake performance - Optimizing HTTP/2 and HTTP/3 settings - Implementing network compression strategies ## Prerequisites - tcpdump, tshark (Wireshark CLI) - ss, netstat, ip utilities - curl with HTTP/2 and HTTP/3 support - Optional: iperf3, mtr, traceroute - Root/admin access for packet capture ## Capabilities ### 1. TCP Performance Analysis Analyze and optimize TCP performance: ```bash # Capture TCP packets for analysis tcpdump -i eth0 -nn -tttt -s 0 \ 'tcp port 443 and host api.example.com' \ -w capture.pcap -c 10000 # Analyze with tshark tshark -r capture.pcap -q -z io,stat,1,"tcp" # Extract

Capture TCP packets for analysis
tcpdump -i eth0 -nn -tttt -s 0 \
Analyze with tshark
tshark -r capture.pcap -q -z io,stat,1,"tcp"
Extract TCP RTT statistics
tshark -r capture.pcap \
awk '{sum+=$1; count++} END {print "Avg RTT:", sum/count*1000, "ms"}'
Check for retransmissions
tshark -r capture.pcap -q -z expert,error
tshark -r capture.pcap -Y "tcp.analysis.retransmission" | wc -lWhat does the network-performance skill do?
Expert skill for network performance analysis and optimization. Analyze packet captures, identify network latency bottlenecks, configure TCP tuning parameters, analyze connection pooling behavior, debug TLS handshake performance, and optimize HTTP/2 and HTTP/3 settings.
How do I install it?
Run `npx skills add a5c-ai/babysitter --skill network-performance --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From a5c-ai/babysitter, a repository with 1,642 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
