[FEATURE] Add agent skills #1139
Description
Describe what the feature does
Most developers today use agents to generate code.
I propose adding an official Motion / Animation skill that enables agents to reliably generate, structure, and reuse animation-related code.
Provide a code example of what the feature should look like
Remotion provides a strong reference implementation for how official skills can be structured and maintained.
