svg-add-primitive

You are extending the system's vocabulary. A new primitive is a long-term commitment — once shipped, presets will depend on it. Your job is to ship it correctly the first time, not to ship it fast.

What was passed in

$ARGUMENTS is the primitive's category-qualified name (e.g., motion.createOrbit, shapes.createStar, filters.createTurbulence). If the argument is missing or unparseable, stop and ask the calling thread to clarify with format <category>.<name>.

Why this skill exists

Without a gatekept extension path, lib/primitives/ quickly accumulates inconsistent signatures, undocumented functions, and primitives used by no one. The discipline below is what makes the library compound rather than sprawl. See D:\github_repository\svg-animation-studio\docs\extension-protocol.md for the rationale.
