Render

Use this skill to open generated or modified CAD and robot-description files in CAD Explorer. The expected input is one or more explicit file paths that already exist or were just generated by another skill.

Supported files: .step, .stp, .glb, .stl, .3mf, .dxf, .urdf, .srdf, .sdf.

Handoff Contract

• Accept explicit file paths from CAD, URDF, SRDF, SDF, SendCutSend, or standard-part workflows.
• Start or reuse CAD Explorer with dev:ensure; do not assume a fixed port. Treat dev:ensure as the viewer liveness check for returned links.
• Treat port reuse as mandatory: if dev:ensure reports local binding/probing denial such as EPERM or EACCES, rerun the same dev:ensure command with the needed local-binding permission/escalation instead of choosing a new port yourself.
• Do not use npm run dev -- --port ..., raw vite dev, or raw vite preview for normal agent handoffs; those bypass the reuse policy and can leave duplicate localhost Explorer servers running.
• Return the printed Explorer URL for each requested file.
• For generation review or visual feedback, prefer the snapshot CLI over opening the viewer manually or using Playwright. Viewer links are still returned for handoff/live review.
• Generate GIFs only for CAD STEP-module parameter animation review. Otherwise use still snapshots, not GIFs.
• If startup fails, report the failure and let the owning skill continue with its non-GUI validation.
