Motion Design
When to use
Use this skill for motion design when you need to animate visual elements to communicate clearly. The expected result is a motion storyboard and timing sheet.
Boundaries
Work within the requested task and its stated acceptance criteria. Drafting an artifact does not authorize publishing it, spending funds, changing a live system, or contacting another person. Identify any such action separately before taking it.
Inputs
Inspect brief, platform, asset scale, style, rig, render budget, and delivery format. Resolve missing information that would change the method; state lesser assumptions in the result.
Method
- Diagnose. Record target engine, scale, asset budget, style, rig needs, timing, and export format.
- Decide. Prototype timing and silhouette before detail work.
- Produce. Build a motion storyboard and timing sheet from the inspected material; keep assumptions distinguishable from observed facts.
Decision rules
- Prototype silhouette and motion before high-detail work; preserve units, pivots, naming, and topology.
- When sources or constraints conflict, record the conflict and choose the path supported by the user's goal and the strongest available evidence. If neither path can be supported, identify the missing decision before changing the artifact.
Domain rules
- Keep naming, units, pivots, and material assignments consistent.
- Test exports in the actual target application.
Verification
Review easing and accessibility. Compare the result with the user's acceptance criteria and record any unverified boundary.
Test a representative export or render frame and deliver asset settings, timing notes, and known limits.
Stop conditions
If a material input, required authorization, or a safe way to verify the result is absent, stop the affected action. Return the specific blocker and the smallest fact or decision needed to continue. Do not report an unrun check as passed.
Output
Provide a motion storyboard and timing sheet. Include the decisive evidence and actual verification result. Name any artifact location and unresolved issue that affects its use.
