Build a motion playground around a production asset

Why use this

1. Changing animation constants directly in a production asset makes quick exploration risky and hard to compare. A visually appealing adjustment may also behave poorly at another viewport, under reduced-motion preferences or after repeated interaction.

2. This job could provide a separate playground where a designer can inspect motion parameters and compare variants. Keeping the original asset untouched lets experimentation remain reversible while making approved values explicit for later implementation.

Why an agent / simpler alternative

Useful judgment

Translate qualitative feedback into parameter adjustments and explain observable motion differences.

Simpler alternative

Use the animation tool’s built-in preview when it already exposes the needed controls.

Unsuitable when

The playground would modify production behaviour or collect user interaction data without approval.

Proposed inputs

1. Name

   Asset and motion specification

   Owner

   Designer

   Minimum scope

   Authorized copy, key states, durations and easing rules

   Quality check

   Identify which properties may vary and which define required behaviour.

2. Name

   Review scenarios

   Owner

   Designer

   Minimum scope

   Viewports, interaction sequences and accessibility preferences

   Quality check

   Include interruption and repeated-trigger cases, not just one ideal playback.

Access and setup — proposed or unknown

Proposed minimum

1. Use a local isolated copy with reversible controls and a clear reset-to-baseline action.

Compatibility unknowns

1. Unknown: asset format, browser rendering, animation dependencies and runtime support.

External actions requiring approval

1. Installing dependencies, modifying production assets or publishing the playground.

Expected deliverable and review checks

Proposed artifact

Playground proposal with control definitions, baseline values and a comparison checklist for designer review.

Critical checks

1. Controls correspond to documented motion properties.

2. Reset reliably returns to the baseline and reduced-motion behaviour is inspectable.

Missing output evidence

No new run or output inspection in this editorial layer; see linked source-specific limits.

Failure signals and proposed responses

1. Signal

   Rapid triggers leave the animation between states.

   Why it matters

   The motion may look correct once but fail during real interaction.

   Proposed response

   Define interruption semantics and include a repeated-trigger review case.

2. Signal

   A scale control crops the asset at small viewports.

   Why it matters

   The chosen motion can hide content or cause layout overflow.

   Proposed response

   Inspect bounds across target sizes and constrain unsafe parameter ranges.

Effort and cost — unknown

Setup work

1. Map asset states and expose a minimal useful control set.

Ongoing review

1. Review variants and record only designer-approved parameter choices.

Unknowns

1. Unknown: implementation effort, rendering consistency and dependency costs.

First check — proposed, unexecuted

Status

proposed_unexecuted

Synthetic fixture

A synthetic specification includes a two-state transition, a rapid retrigger and a small viewport with reduced motion enabled.

Acceptance checks

1. The proposed checklist covers interruption, bounds and reduced-motion behaviour.

2. A reset restores all baseline values.

Stop conditions

1. Production edits, unsupported asset conversion or public hosting is required.

Limits

1. A playground supports design judgment; it does not establish production accessibility or cross-browser performance.
