solidcraft-mechanisms SKILL.md skillA
solidcraft-mechanisms from randomonkey05/solidcraft-agent-skills is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Use when building, driving or animating an assembly or mechanism in SolidCraft through its MCP server - components, grounding, joints and joint origins, rigid groups, motion links, closed loops such as an actuator on a hinged panel or a linkage, contact sets, motion studies, degrees of freedom - or when a drive moves nothing, stops early or a part jumps when it is joined. To model the parts themselves, use solidcraft-modeling.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SolidCraft mechanisms
## Overview
An assembly is components placed by joints. Work the mechanism out as world points and axes first: every pin, slide and hinge, which part each one joins, and the value you expect at each pose. Then give every joint origin by those coordinates, and check each step against a number you computed yourself. A drive that reports success can still have moved nothing. Command shapes, a worked example, the traps and reply sizes are in `reference.md` next to this file. To build the parts themselves, use `solidcraft-modeling`.
Written against SolidCraft `main` after 0.11.1, which counts the degrees of freedom of closed loops, carries motion links through chains made in any order, and answers drives in degrees with `moved` (and a `reason` when nothing could move).
## Before the first call
1. In SolidCraft's own chat or any MCP client, call `skill_reference {"skill":"solidcraft-mechanisms"}`. Elsewhere, read `reference.md`.
2. **Open:** if the design is not open yet, run `open {path}`. When the server is bridged to the app and the current design is `dirty`, ask before opening anything.

How to install
mdr add randomonkey05/solidcraft-agent-skills/solidcraft-mechanisms@sha256:e3baf1784bedcf98The line at the top of this page pins the label git:20261027.9af30e1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
