What it can do

  • Gives the agent 113 JSON-schema commands for geometry, ports, mesh, parameters, sessions, 1D/2D results, far-field export and optimisation studies.
  • A guard layer stops known mistakes, such as simulating without rebuilding after a parameter change or treating complex S11 as dB.
  • Keeps the modeller session and the read-only results session strictly separate.
  • Writes an audit trail of each call and produces self-contained HTML reports.

Limitations

  • The guard layer only covers known patterns; the author advises human review at key steps.
  • Needs Python 3.13 or later and uv; the skill text is in Chinese.
  • Despite the repository name, it is a command-line toolchain used through skills, not an MCP server.
