A bounded sample of popular skills mapped to this occupation, with at most one Skill from each GitHub repository. The complete mapped list follows.

lab-hardware-cad

K-Dense-AI/scientific-agent-skills

Design custom laboratory hardware as parametric build123d models and export fabrication-ready STEP, STL, and DXF files - microfluidic chips and molds, optomechanical mounts and breadboard adapters, cuvette and microplate holders, tube racks, animal-behavior rigs, and 3D-printed instrument fixtures. Use when a research task needs a physical part that must mate with standardized labware, an optical table, a cage system, or a printer, CNC, or laser process.

earthtojake/text-to-cad

Find, evaluate, and download common purchasable CAD parts from step.parts, including named off-the-shelf actuators, servos, motors, electronics boards, connectors, screws, bolts, nuts, washers, bearings, standoffs, and other catalog components. Use when Codex needs to search the hosted step.parts catalog before creating simplified placeholder geometry, resolve fuzzy part names, standards, aliases, or dimensions, choose a matching part, fetch a canonical .step file, verify checksums, or use the step.parts API/OpenAPI/catalog endpoints for standard part discovery.

huxingyi/dust3d

Open a dust3d .ds3 file and export it to a specific format (.obj, .glb, or .fbx) using the dust3d command-line interface.

mitsuhiko/agent-stuff

Create and render OpenSCAD 3D models. Generate preview images from multiple angles, extract customizable parameters, validate syntax, and export STL files for 3D printing platforms like MakerWorld.

dust3d-generate-from-image

huxingyi/dust3d

Generate a Dust3D 3D model from a 2D turnaround reference image by tracing body parts as tube-shaped node chains, writing an XML file, and running dust3d to produce a .obj mesh, a .ds3 document, and the source .xml file.

mitsuhiko/agent-stuff

Create and render OpenSCAD 3D models. Generate preview images from multiple angles, extract customizable parameters, validate syntax, and export STL files for 3D printing platforms like MakerWorld.

qwen-mm-plugins-freecad

QwenLM/Qwen-MM-Plugins

Use whenever a task involves parametric CAD in FreeCAD — modeling parts and assemblies, editing object properties, technical drawings, importing/exporting STEP/STL/OBJ/DXF, PDF/Excel reports from a model, or finite-element (FEM/CalculiX) analysis. Requires a running FreeCAD instance with the FreeCADMCP addon (see Prerequisite).

a5c-ai/babysitter

Specialized skill for geometric dimensioning and tolerancing specification per ASME Y14.5 and ISO 1101

hashgraph-online/awesome-codex-plugins

Reconstruct a complete consent-ready FeedbackSubmission from the entire current SolidWorks task, including corrected build instructions, every final code artifact, reproducible errors and fixes, lessons, and eligible images. Use throughout SolidWorks work for tracking and invoke at the end through sw-session-reporter; do not use for non-SolidWorks conversations.

hashgraph-online/awesome-codex-plugins

Load mandatory SolidWorks conventions, design rules, task-relevant knowledge documents, standards data, and initial design-rule checks before any modeling or CAD code. Use at the beginning of every SolidWorks create, modify, repair, assembly, drawing, or API task, before touching SolidWorks; also use its final phase before save and export.

kellerlabs/homeracker

Relentlessly interview the creator of a HomeRacker OpenSCAD model about every design decision, then fold the answers into the model's documentation. Use this skill during planning of a new model, or after a model (or a change to one) is built, to pressure-test the design and produce the most comprehensive yet concise docs possible. USE FOR: grilling a model's parameters/defaults/geometry/print choices, filling gaps a newbie couldn't understand, improving model README / configuration & printing guides / MakerWorld descriptions, rendering missing parameter-config images, and creating or updating a model's decision record (ADR). DO NOT USE FOR: writing the OpenSCAD geometry itself (use the @makerworld-model agent), extracting MakerWorld descriptions from the web (use the makerworld-description skill), or routine version/config/dependency changes.

mcneel/RhinoMCP

Start a single Rhino MCP session. Accepts a version argument (e.g. `8`, `WIP`) and an optional explicit port. Walks forward from `10500` to pick a free port if none was given. On macOS this opens a new document in the running Rhino; on Windows it launches a new Rhino process. Use when the user asks to start a Rhino MCP session — for N parallel Rhinos use `/launch-rhinos` instead.

mcneel/RhinoMCP

Spin up N Rhino MCP sessions in parallel and fan out one agent per Rhino. Use when the user wants multiple Rhinos running simultaneously with each agent driving its own — e.g. "spawn 3 agents and have each launch Rhino", "run 5 Rhino tasks in parallel". For a single Rhino, use `/launch-rhino` instead.
