The instructions your model reads when the skill loads.
<quick_start> Extract frames and audio from a video:
# Extract 1 frame + audio segment per second (default)
~/.claude/skills/extract-video-frames/scripts/extract-frames.sh input.mp4
# Extract 1 frame + audio segment every 2 seconds
~/.claude/skills/extract-video-frames/scripts/extract-frames.sh input.mp4 2
# Specify custom output directory
~/.claude/skills/extract-video-frames/scripts/extract-frames.sh input.mp4 1 ./my-frames
The script creates:
frames/ directory with PNG files named frame_001.png, frame_002.png, etc.frames/audio_001.aac, audio_002.aac, etc. (when audio exists, aligned 1:1 with frames)frames/full_audio.aac (complete audio track, when audio exists)frames/manifest.json with frame and audio metadata for the reviewing agent
