CAD Skills
earthtojake
Open-source library of agent skills for CAD, robotics, fabrication, and simulation — generate STEP/STL, URDF/SRDF/SDF, DXF, and slicer G-code from prompts.
Key features
- Prompt-to-CAD Generation: The CAD skill creates and edits parametric CAD models from natural language or image requests, exporting to STEP, STL, 3MF, and GLB.
- URDF Robot Description: Writes robot structure files with links, joints, limits, inertials, and meshes ready for ROS-based stacks.
- SRDF for MoveIt2: Adds planning groups, end effectors, named poses, and collision rules on top of a URDF for MoveIt2 planning.
- SDF Simulation Worlds: Creates simulator models and worlds with frames, physics, sensors, and lights.
- 2D DXF Drawings: Produces cut-ready DXF profiles, templates, gaskets, and layouts from Python or CAD geometry.
- G-code Slicing: Slices supported mesh files into validated, printer-profiled FDM G-code using real slicer CLIs.
- Bambu Lab Print Jobs: Dry runs, uploads, and cautiously starts local Bambu Lab prints from validated G-code.
- CAD Viewer Previews: Local browser previews for CAD, G-code, URDF, and other robot files for fast agent iteration.
Best for
- Agentic Mechanical Design: Let a coding agent iterate on brackets, flanges, and enclosures directly from natural-language specs.
- Robot Description Authoring: Generate URDF/SRDF/SDF files for new robot arms or mobile bases without hand-writing XML.
- Rapid Prototyping: Take a CAD model to sliced, printer-ready G-code and kick off a Bambu Lab print from within an agent workflow.
- Custom Part Fabrication: Produce DXF/STEP files pre-checked for SendCutSend, then order laser-cut or CNC parts.
- Simulation Setup: Author SDF worlds for physics simulators with the right frames, sensors, and lighting for robotics research.
- Off-the-Shelf Sourcing: Use step.parts to pull ready-made STEP models for common hardware like screws, bearings, and connectors.
Lovable
Lovable
Build software products using a conversational chat interface that edits and runs your web app in real time.
Key features
- Chat-Driven Editor: Accepts natural-language instructions and translates them into concrete code edits across the project, enabling product development through conversation instead of manual file edits.
- Live Rebuild & Preview: Every code change is immediately built and rendered in a live iframe preview so users can see the application state and UI results in real time.
- Console Access for Debugging: The agent can read application console logs to identify runtime errors and use that information to debug and patch code directly.
- Asset Upload & Use: Users can upload images and other assets to projects and Lovable will incorporate them into the application and responses.
- Complete-Change Enforcement: Enforces making complete, runnable edits (no partial implementations or missing imports) to avoid broken builds and ensure every response yields a working preview.
- Opinionated Frontend Guidance: Follows preferred stack and style rules (React, Tailwind, shadcn/ui and other recommended libs) and coding guidelines to produce consistent, minimal, production-oriented code.
- Minimalist Implementation Philosophy: Prioritizes simple, pragmatic changes over overengineering—implements the minimum changes needed to satisfy requests while keeping code elegant.
- Real-time Codebase Interaction: Performs file creation, modification and targeted replacements in the repo via chat with an editing format and tooling that align with iterative agent-driven workflows.
- Conversational interface to request code changes and new features
- Applies edits directly to project codebase and triggers immediate build/render
- Live preview iframe showing application changes in real time
- Access to application console logs to aid debugging
- Support for user-uploaded images integrated into the project
- Enforced full edits (no partial or placeholder changes); imports must exist
- Opinionated guidance for frontend stacks (React, Tailwind, shadcn/ui, lucide-react, recharts, @tanstack/react-query)
- Focus on minimal, pragmatic implementations and avoiding overengineering
Best for
- Rapid Prototyping: Convert product ideas or written feature requests into working web app prototypes through a few chat messages and see results instantly in the preview.
- Interactive Bug Fixing: Describe observed runtime errors; Lovable inspects console logs, applies fixes, and returns an updated live build demonstrating the resolved issue.
- UI Iteration and Design Refinement: Ask for layout or style changes and get immediate code edits with a live preview to iterate quickly on UX adjustments.
- Onboarding & Learning: New developers or designers can describe desired functionality and see a runnable implementation, accelerating ramp-up and knowledge transfer.
- Pair Programming Assistant: Use Lovable as a conversational teammate to implement features, create components, or refactor parts of the frontend while maintaining working builds.
- Asset Integration: Upload images or media and instruct Lovable to incorporate them into pages, galleries, or components without manual file handling.
- Enforced Deployment-Ready Edits: Produce consistent, minimal, and complete changes that reduce the time between idea and a deployable frontend artifact.
- Rapidly prototyping and iterating web application UIs through chat
- Making targeted frontend code fixes and component implementations
- Debugging runtime issues by viewing console logs and applying fixes
- Onboarding or pair-programming assistance where the agent edits the repo live
- Integrating user-provided assets (images) into the running project
