What it can do

  • Gives the agent assembly maps, csproj settings and loading rules so generated plug-in code targets .NET 10 instead of older .NET Framework patterns.
  • Covers Civil 3D objects (alignments, surfaces, corridors, pipe networks, data shortcuts) and the Plant 3D P&ID data manager and pipe routing APIs in separate skill files.
  • Registers `dotnet new acad` and `dotnet new civil` project templates and explains bundle packaging and accoreconsole testing.
  • Tells the agent to search local SDK samples and Autodesk's Help MCP server before inventing API calls.

Limitations

  • A coding aid for plug-in development; it does not connect an agent to a running AutoCAD or Civil 3D session.
  • Aimed at .NET 10 releases; older releases built on .NET Framework 4.8 or .NET 8 need different project settings.
  • The installer copies files into your project and does not remove them on uninstall.
