SKILL.md

Plugin installs: Before setup or freshness commands, follow plugin execution rules when this skill is inside a HyperFrames plugin. Standalone installs keep the update instructions below.

HyperFrames Keyframes

Keyframes are a pose contract: visible states, continuous subject identity, seek-safe runtime, verified pixels.

Use hyperframes-animation for broad scene recipes. Use hyperframes-cli for full command docs. Use references/keyframe-patterns.md only when choosing implementation mechanisms, not visual style.

Creator editing boundary

Keyframes own visual motion, not clip assembly. Source-range hard cuts, trim,
splice, and reorder belong to /hyperframes-core: author one media element per
kept range, place it with data-start and data-duration, and select its source
offset with data-media-start. Adjacent ranges make a hard cut. A crossfade
uses overlapping clips on different tracks plus visual opacity keyframes; sound
fades use /hyperframes-audio.
