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.

i-have-adhd

Coding-agent skill that forces action-first, numbered answers — kills the 'Great question! Let me think...' preamble in Claude Code, Codex, and friends.
Key features
- Action-First Output Rule: Every response leads with the next concrete action instead of preamble.
- Numbered Multi-Step Tasks: Coding tasks come back as numbered lists capped at 5 items each.
- Preamble & Closer Suppression: Eliminates 'Great question!', 'Hope this helps', and other filler.
- Specific Time Estimates: Forces the agent to answer with minutes rather than vague 'a bit' phrasing.
- One-Command Install: /i-have-adhd in Claude Code, $i-have-adhd in Codex, or persistent activation via ~/.claude/.i-have-adhd.
- Auto-Update in Claude Code: Claude Code fetches the skill from GitHub and keeps it up to date — no local clone needed.
- Multi-Language Skill Docs: README available in English, Simplified Chinese, Japanese, Korean, Vietnamese, and Portuguese (BR).
- Fork-and-Tune: Copy skills/i-have-adhd/SKILL.md, edit the 10 rules to taste, restart the agent, and re-invoke.
Best for
- Reduce Preamble Fatigue: Developers who lose time scanning past 'Great question!' openings get straight-to-the-point agent output.
- ADHD-Friendly Workflow: Neurodivergent developers get responses formatted the way their attention can actually consume.
- Terminal-First Sessions: Users driving Claude Code or Codex from a terminal want short, numbered instructions rather than essays.
- Team Style Standard: Teams adopt the skill so every developer's coding agent responds in the same terse format.
- Custom Response Rules: Fork the SKILL.md and hand-tune the 10 rules to fit an internal engineering culture or accessibility need.
