About
SysMLv2 Editor is a Visual Studio Code extension for writing SysML v2 models in the textual notation, developed by Change Vision, Inc. Models are plain .sysml files, so they can be tracked in Git, compared in pull requests, and reviewed alongside source code.
Features include syntax highlighting, real-time validation against the SysML v2 grammar, navigate to definition, an outline view, and diagram generation for reviewing structure and behavior. Diagrams are read-only; editing happens in the text. For editing directly on diagrams, Change Vision offers SysMLv2 Modeler (early access).
SysMLv2 Editor runs on Windows, macOS, and Linux. It is included with an Astah SysML, Astah System Safety, or Astah Faculty Site License, with no separate purchase, and a 20-day free trial is available. It does not import SysML v1 models from Astah SysML.

About
VisualEther turns Wireshark packet captures (PCAP/PCAPNG) into readable sequence diagrams — and lets AI coding agents like Claude Code explain, in plain English, why a network session failed.
Wireshark shows every packet but not the conversation. VisualEther draws it directly from the capture — frame-accurate and reproducible — using 82+ built-in protocol templates spanning 5G NR, 5G core, LTE, IMS/VoLTE, SIP/RTP, BGP, OSPF, DNS, HTTP/2, HTTP/3, TLS, Kerberos, Diameter, GTP, and industrial protocols (Modbus, DNP3, EtherNet/IP).
A built-in MCP server extracts only the messages and fields that matter, so an AI agent reads kilobytes of structured data instead of megabytes of raw packets — then runs an author-debug-verify loop, citing frame numbers as evidence. Built on tshark: anything Wireshark can dissect, VisualEther can diagram.
See, Triage, Diagnose, Automate. Windows (winget), macOS (Homebrew), Linux (apt/dnf). Free Community edition; paid Professional and Server editions
