SolidCraft-Agent-Skills
Early collection of agent skills for modeling in SolidCraft through its MCP server, focused on working around the limits of the SolidCraft release they were checked against.
What it does and how it connects
This is a collection of agent skills for modeling in SolidCraft through its MCP server, written for Claude and other agents that read the Agent Skills format. The version number follows the SolidCraft release the skills were written and checked against, currently 0.24, and the README calls it an early, evolving collection rather than a finished one.
The focus is working around the limits of SolidCraft while it is in beta: crashes, app hangs, silently wrong booleans, and fillets that fail. Skills cover modeling, editing, checking, mechanisms, assemblies, robust build order, speed modeling lessons, sheet metal, shells and tangent arcs, sweep and boolean hangs, 3D print DFM, DFM review, engineering drawings, and requirements and sanity checks.
Four of the skills are copied unchanged from SolidCraft 0.24.0, and others are adapted from text-to-cad, mechanical-cad-skills, and solidworks-automation-skill, with the rest original to this repo. The README states the skills reduce the failure rate on complex geometry but do not remove it, and advises saving checkpoints because booleans on swept or spherical bodies, shells on thin walls, and fillets near knife edges can still hang the app.

Recurring errors it addresses
Error Index entries this tool is built to reduce or work around.
- A STEP export from SolidCraft lost the side faces on 3 of 4 tapered legs when opened in other CAD tools, leaving only end discs. SolidCraft read its own file back fine; the fault was which ring of the cone face the loop started on, which other readers depend on.Error Index
- After a shell on a tapered, filleted box, four inner corner fillet edges miss their surface by up to 0.0198 mm. SolidCraft shows the body and re-imports it without complaint; FreeCAD 1.1.4, used as an outside reader, flags the four faces as invalid.Error Index
- Booleans on lofted B-spline bodies are 1 to 2 orders of magnitude slower than on prismatic bodies, and a join between bodies sharing faces of the same loft fails after 5 min 11 s with 'no result', while the same part builds fine in FreeCAD/OCCT.Error Index
- A fillet fails with "both faces next to the edge must be planar" on a part the user built easily in Onshape.Error Index
- A large sketch imported from Fusion 360 into SolidCraft stalls on extrude, showing computing indefinitely and never finishing the operation.Error Index
