What it can do
- Motion Catalog: Returns the catalog of verified motion primitives (names, purpose, parameter schemas, defaults) plus the authoring rules for writing a MotionSpec. Call this FIRST, then write the spec
- Motion Validate: Checks a MotionSpec against the schema, the primitive allow-list, parameter bounds and injection rules. Fail-closed: returns ok=false with precise errors. Use to pre-check a spec befo

MotionSpec verifies and compiles the UI animation in AI-generated web apps. Keyless tools: motion_catalog (40 verified motion primitives + authoring rules) and motion_validate (fail-closed validation against WCAG 2.2.2 / 2.3.3 rules); nothing submitted is stored. A validated spec compiles deterministically to reduced-motion-safe, on-budget GSAP/WAAPI-CSS. MIT core on npm (motionspec). Not Motion.dev / Framer Motion, not the Android/iOS MotionSpec classes, not the usemotion.com calendar app, not a video generator.

| motion_validate | Checks a MotionSpec against the schema, the primitive allow-list, parameter bounds and injection rules. Fail-closed: returns ok=false with precise errors. Use to pre-check a spec before compiling. |
