SolidWorks Automation Skill connects coding agents to desktop CAD. It ships three peer entry points that share one capability registry (`capabilities.yaml`): an agent Skill, an MCP server with about 60 tools, and a Windows desktop app called CAD Studio. You pick one; no separate runtime service has to be started.

Its main idea is that a tool returning success is not the same as the task being done. An internal Execution Core verifies results, decides how to recover from backend failures and writes a structured trace. When no existing tool covers a request it returns a `CAPABILITY_GAP` instead of improvising, and it does not run unknown code from the internet on its own.

Each capability carries a status in the registry: verified, stable, pilot or blocked. Threaded holes and open-format export are marked verified, while gears, motion studies, FEA and mold work are still pilot and need human review. The README lists SolidWorks 2024/2026 and AutoCAD 2024 as the real-machine baselines; without SolidWorks it can still write STEP, STL, GLB and similar files through OCCT, but native SLDPRT/SLDASM/SLDDRW need a licensed SolidWorks.

This write-up is based on the project's README and public repository data. We have not hand-tested the tool. Data as of 2026-10-18.

Features

01Three entry points sharing one capability registry: Skill, MCP and CAD Studio
02Verification-first completion: tool success is not treated as task success
03Part modeling, engineering drawings, threaded holes, assemblies and interference checks
04Writes STEP, STL, GLB and other open formats via OCCT without SolidWorks
02

Why choose it

+Verifies CAD results before reporting success, so an agent's "done" is backed by evidence.
+Each capability is labeled verified, stable, pilot or blocked, so you know what can run unattended.
+Works as a Skill, an MCP server or a desktop app, so it fits Codex, Claude Code, Cursor or a GUI workflow.

Trade-offs

!Native SolidWorks files require a licensed SolidWorks install, which runs only on Windows.
!Many areas such as gears, motion, FEA and mold design are still pilot and need manual review.
!Much of the README and documentation is written in Chinese.
