What it does
Add a measured sound pass to a motion-graphics video made with Claude Code (HyperFrames, Remotion, GSAP, Claude Motion or the motion-broll skill). Builds a cue list, checks the music's beat grid against the kick drums, lands cuts on the beat, places one real sound effect per cue from a bundled CC0 library, mixes to -16 LUFS with true peaks below -4 dBFS measured on the exported MP4, and proves it with frames, waveforms and 5 timestamps for a human to check. Use when someone wants sound effects, sound design or music added to a motion-graphics video, or says their AI video sounds like cheap beeps.
Sound effects
Claude can't hear. So this skill never judges sound by feel: it measures every step, and it hands the user 5 timestamps to check with headphones. It never says "it sounds good".
The approach is Vox's sound-pass prompt (@Voxyz_ai, https://x.com/Voxyz_ai/status/2109358372873183564, 11 Oct 2026). Keep that credit.
Default kit (use this first)
sfx/manifest.json → default_kit: one sound per core category, picked by ear by Bart (12 Oct 2026). Use it unless the user asks for something else.
| Category | Sound | Where it comes from |
|---|---|---|
| whoosh | "Whoosh" by qubodup | bundled sfx/kit/whoosh.ogg (CC0) |
| click | "Classic Click" by adh.dreaming | bundled sfx/kit/click.ogg (CC0) |
| pop | "POP SFX Neutral" by ethernel0 | bundled sfx/kit/pop.ogg (CC0) |
| riser | "Cinematic Riser #3 subtle" | bundled sfx/kit/riser.ogg (CC0) |
| impact | "soft_impact3" by peoplearehappy | bundled sfx/kit/impact.ogg (CC0) |
| tick | "Click / Tick" by Squirrel_404 | bundled sfx/kit/tick.ogg (CC0) |
| typing | Mixkit "Fast laptop keyboard typing" (#1392) | downloaded at runtime into <out>/sound-effects-cache/ (Mixkit licence: never commit it) |
Everything else in the manifest is an alternative (alt_categories lists which categories can stand in for each other). See TOP-PICKS.md for credits.
