# Rendered joint motion validation

The maintained [trace protocol](https://github.com/Valpatel/cad-agent/blob/dev/skills/cad-motion-validation/references/trace-protocol.md) ships with the
[cad-motion-validation skill](../skills/cad-motion-validation/SKILL.md), including when the workflow installer
copies the skill to a different machine. It documents the independent CAD reference, actual renderer capture,
`cad-agent motion-trace` CLI, required coverage, diagnostics and evidence limits.
