Research direction

Start with skills/motion-graphics/agents/builder.md and skills/motion-graphics/SKILL.md to trace the Builder's dispatch context, then inspect categories/charts/module.md and categories/stat/module.md. Verify that the motion-principles.md and data-in-motion.md references are added at the requested points and that all links resolve to the existing hyperframes-creative files.

Description

enhancement triage/needs-triage
Problem

skills/motion-graphics never references skills/hyperframes-creative (no mention in any file on main). As a result, hyperframes-creative/references/motion-principles.md is not on the motion-graphics read path, even though motion-graphics is the most motion-first workflow in the repo.

I checked whether its guardrails are covered elsewhere on that path (SKILL.md, agents/director.md, agents/builder.md, references/builder-contract.md, references/motion-vocabulary.md, plus the SKILL.md of hyperframes, hyperframes-core and hyperframes-animation). They mostly are not:

motion-principles.md guardrail Covered on the motion-graphics path?
Vary eases (≤2 tweens per scene with the same ease) No
.out for entrances, .in for exits, .inOut for moves No (only per-primitive examples in motion-vocabulary.md)
Vary duration (slowest scene ~3× the fastest) No
Vary entrance direction (not always y:30, opacity:0) No
Build / breathe / resolve scene structure Partly (categories/kinetic-type only: Hook → Build → Punch → Resolve)
Stagger by importance, total stagger < 500ms No
Exits faster than entrances No
Offset the first tween 0.1–0.3s No

The only route to the file today is indirect (hyperframes-animation/adapters/animate-text.md, or the capability table in hyperframes/SKILL.md), so whether the Builder reads it depends on the agent's own initiative.

hyperframes-creative/references/data-in-motion.md has the same gap for the charts and stat categories.

Proposed solution

A small docs-only change:

  1. skills/motion-graphics/agents/builder.md — add a line under "Critical correctness" (or a new "Motion quality" heading): read ../hyperframes-creative/references/motion-principles.md before writing the timeline.
  2. skills/motion-graphics/SKILL.md Step 4 — add that file to the Builder's dispatch context list.
  3. skills/motion-graphics/categories/charts/module.md and categories/stat/module.md — reference ../hyperframes-creative/references/data-in-motion.md.

Alternatives considered

Inlining a condensed version into references/motion-vocabulary.md. This avoids a cross-skill read but duplicates content that would drift from the original, so a link seems better.

Additional context

While building short HTML motion pieces with an AI coding assistant (outside HyperFrames), I hit exactly the failure modes this file warns about: uniform easing, missing exits, flat timing. That is what led me to compare the motion-graphics read path against motion-principles.md. I have not measured the effect inside the motion-graphics workflow itself.
