Use when a user wants to fill a portable music player (Walkman, iPod, USB drive) with a curated random selection from a music library on a NAS or local directory. Handles format filtering, artist/album diversity balancing, and size targeting.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

<!-- Generated by scripts/build-adapters.sh. Do not edit directly. -->

# fill-music-player

Curates a DJ-balanced selection of tracks from a source music library and copies them to a portable player, respecting device capacity and supported formats.

## Quick Reference

```bash
# Dry run first (always recommend this)
fill-music-player --source /Volumes/music --dest /Volumes/WALKMAN/MUSIC --dry-run

# Copy for real
fill-music-player --source /Volumes/music --dest /Volumes/WALKMAN/MUSIC

# Or run the script directly with uv
uv run fill_music_player.py --source ~/Music --dest /Volumes/USB --dry-run
```

Run `fill-music-player --help` for all options.

## Key Parameters

| Flag | Default | Purpose |
|------|---------|---------|
| `--source` / `-s` | required | Source music root (NAS mount, ~/Music, etc.) |
| `--dest` / `-d` | required | Player destination directory |
| `--target-gb` | 95% of free space | How many GB to fill |
| `--formats` | mp3,m4a,wma,aac | Allowed extensions |
| `--max-per-artist` | 4 | Artist diversity cap |
| `--max-per-album` | 3 | Album diversity cap |
| `--skip-dirs` | (none) | Top-level dirs to skip |
| `--dry-run` | false | Preview without copying |

How to install

The exact contents, by fingerprint
mdr add oleg-koval/agent-skills/fill-music-player@sha256:37f0ae100f350857

The line at the top of this page pins the label git:20260828.aaaffd4, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
