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.

Clawdbot

clawdbot (open-source community)

Free

Clawdbot is an open-source, locally-running personal AI assistant that runs on any OS and is extended via installable skills.

Key features

  • Local Execution: Runs entirely on the user's device (any OS) allowing workflows and skills to execute locally, reducing reliance on external cloud services and improving data control.
  • Skill System & ClawdHub: Modular skill architecture with a public registry (ClawdHub) to search, install, update, and publish skills that extend capabilities (browser automation, messaging, auditing, etc.).
  • Cross-Platform Installers: Official installer scripts for macOS, Linux, and Windows that detect package managers, install Node.js as needed, install clawdbot globally, and run onboarding for new installs.
  • CLI and TUI Tools: Rich command-line and terminal UI with commands for onboarding, daemon/gateway management, model authentication, security audits, snapshots, and structured agent runs.
  • Integrations & Channels: Connectors and integrations for multiple chat providers and models (visual integrations grid on the site); skills exist to connect to Claude and messaging platforms like Slack and Telegram.
  • Auto-Update & Sandbox Features: Auto-updater skills and sandboxing tools to update Clawdbot and manage skill execution safely, plus tools to audit installed skills for security and policy compliance.
  • Local runtime designed to run on user machine (Any OS) with Node.js >=22 requirement
  • Extensible skills system with public registry ClawdHub and a skills CLI for search/install/publish
  • Installer scripts for macOS/Linux and Windows that install dependencies, Node.js, and clawdbot globally
  • Gateway daemon (launchd/systemd user service) to keep background agent running
  • Supports pairing and delivering assistant messages to many chat providers (WhatsApp, Telegram, Slack, Discord, Signal, iMessage/BlueBubbles, Microsoft Teams, Matrix, Zalo, WebChat)
  • Skills follow Anthropic Agent Skill convention for compatibility
  • Tooling and community skills include: headless browser automation (agent-browser), encrypted messaging (clawdlink), auto-updater, skills-audit, skills-search, claude-connect (connect Claude models), and documentation/navigation skills
  • CLI commands and maintenance utilities (clawdbot doctor for diagnostics/migrations, clawdbot onboard)
  • Open-source TypeScript codebase with GitHub-hosted website (Astro) and CI deploys to GitHub Pages
  • Installer supports package manager detection and can install Homebrew (macOS) and Node.js if missing

Best for

  • Personal Productivity Assistant: Automate daily tasks (email summaries, calendar management, note-taking) locally with installed skills to preserve privacy.
  • Developer Workflows: Use workspace templates, code generation, and repo-aware skills to assist with coding, onboarding, and repository maintenance directly from the CLI.
  • Automated Browser Tasks: Run headless browser automation via an agent-browser skill to perform web scraping, UI testing, or multi-step web workflows on behalf of the user.
  • Secure Instance Messaging: Use clawdlink to send encrypted messages between Clawdbot instances for coordinated workflows across machines.
  • Skill Security and Compliance: Run skills-audit to inspect locally installed skills for security or policy issues before enabling them in production scenarios.
  • Model Bridging and Continuous Connections: Connect hosted models (for example, Claude) to Clawdbot via connector skills to keep a model connected 24/7 and extend local capabilities with remote models when desired.
  • Personal productivity assistant running locally to manage tasks, fetch docs, and automate workflows
  • Bridging and delivering assistant responses into multiple chat providers and team channels
  • Automating browser workflows and scraping via headless browser skills under agent control
  • Secure peer-to-peer Clawdbot-to-Clawdbot messaging and encrypted inter-agent communication
  • Extending assistant with custom skills for CI/CD, code assistance, documentation search, and system automation
  • Auditing locally installed skills for security/policy compliance before enabling them
