CAD Skills

earthtojake

Free

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.

Github Copilot

GitHub

Paid

An AI-powered coding assistant that suggests code, completes functions, and offers chat-driven coding help across editors and GitHub.

Key features

  • Contextual Code Completion: Provides single-line, multi-line, and whole-function suggestions based on local file context, open repositories, and installed project files to speed coding and reduce boilerplate.
  • Copilot Chat: An interactive chat interface embedded in supported IDEs, GitHub.com, GitHub Mobile, and the CLI that answers coding questions, explains code, and generates fixes or tests on request.
  • IDE & Platform Integration: Native plugins and support for Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse, Xcode, Windows Terminal, GitHub CLI, and GitHub.com allowing seamless in-editor assistance and workflows.
  • Copilot CLI & Agents: Command-line tools and coding agents (public preview) that let developers query Copilot for changes to local files, list/manage GitHub resources, and run agent-driven automation from the terminal.
  • Code Review Suggestions: Automated AI-generated code review suggestions and recommendations to help identify issues, suggest improvements, and accelerate pull request review cycles.
  • Governance & Safety Controls: Filters for off-topic/harmful output, scanning for vulnerable code, and options to detect or exclude suggestions that match public GitHub code along with organization-level policy controls.
  • Copilot Extensions: A plugin model that allows third-party and custom integrations to extend Copilot Chat capabilities with external tools, services, and private knowledge sources.
  • Multi-language & Framework Support: Strong support for popular languages (Python, JavaScript, TypeScript, Ruby, Go, C#, C++, etc.), database query generation, API scaffolding, and infrastructure-as-code patterns.
  • Context-aware code completions (lines & functions)
  • Copilot Chat for interactive coding help
  • Coding agents for multi-step tasks
  • Multiple model access and model selection (paid tiers)
  • IDE, GitHub.com, Mobile and CLI integrations
  • Admin controls, policy and user management for orgs
  • Configurable data usage and training exclusions
  • Inline code completions: whole lines or entire functions suggested in-editor.
  • Copilot Chat: chat interface available in GitHub website, supported IDEs, GitHub Mobile, and Windows Terminal.
  • Copilot CLI: terminal-based command line interface to query and modify local files and interact with GitHub.com (e.g., list PRs, create issues).
  • Copilot Extensions: GitHub Apps that integrate external tools into Copilot Chat; can be published on GitHub Marketplace.
  • Copilot Edits: contextual code edits driven by prompts or chat within IDEs.
  • Copilot Code Review: AI-generated review suggestions to improve code quality.
  • IDE support: Visual Studio Code, Visual Studio, JetBrains IDEs, Eclipse IDE, Xcode (and other supported editors).
  • Platform integrations: native integration on GitHub.com, GitHub Mobile, Windows Terminal Canary, and GitHub CLI.
  • Governance and controls: options to allow/deny suggestions matching public code, organization-level access (Enterprise), and filters for off-topic/harmful/vulnerable outputs.

Best for

  • Accelerated Feature Implementation: Generate function bodies, boilerplate, and API client stubs from inline prompts to speed building new features across multiple languages and frameworks.
  • Debugging and Bug Fixing: Use Copilot Chat to explain stack traces, suggest fixes, or propose test cases that reproduce and resolve defects within the developer's codebase.
  • Test Generation and Coverage: Automatically create unit tests, integration test scaffolding, and example inputs/outputs to increase coverage and speed QA cycles.
  • Code Review Assistance: Provide automated review suggestions on pull requests to surface potential bugs, security concerns, or opportunities to refactor and optimize.
  • DevOps and Infrastructure as Code: Generate Terraform, Dockerfile, and CI configuration snippets, or translate deployment patterns into reproducible infrastructure code.
  • Onboarding and Documentation: Help new developers understand code by summarizing functions, generating README snippets, and producing inline documentation or usage examples.
  • CLI and Mobile Workflows: Interact with repositories and get coding assistance directly from the terminal or GitHub Mobile for quick edits, issue triage, or code exploration on the go.
  • Speeding up feature development with suggested code snippets
  • Debugging and explaining code via chat
  • Automating repetitive coding tasks using agents
  • Onboarding new developers with contextual suggestions
