2 things to look at

no licenseNo license file was found in the repository. Code published without one is not open source by default, so using it at work is a question for whoever answers licensing questions where you are.
2 stars2 stars. Stars are a popularity signal and not a quality one, but at this level it is likely that nobody has read this closely except its author, and you would be relying on your own review.

What its author says it does

Copied from the file, not written here

Trim a video to a [t0, t1] time range using ffmpeg. Stream-copies where possible to avoid re-encoding. Use as the cheap building block for cutting source video into per-short slices.

cut-clip

Thin ffmpeg trim wrapper.

Inputs

input: video path
t0: start seconds (float)
t1: end seconds (float)
out: output path
reencode (optional): bool, default false. Set true if cut must be frame-accurate at a non-keyframe.

Output

mp4 cut to the requested range.

How

Default (stream copy, fast, ±1 keyframe accuracy): ffmpeg -ss <t0> -to <t1> -i <in> -c copy -avoid_negative_ts make_zero <out>
Re-encode (frame-accurate): ffmpeg -i <in> -ss <t0> -to <t1> -c:v libx264 -preset veryfast -crf 18 -c:a aac <out>

Invoke

.claude/skills/cut-clip/cut-clip.sh <input> <t0> <t1> <out> [reencode]

Idempotent via mtime check (skips when out is newer than input).
