What is dj-usb-maker?

A tool that prepares a USB stick from a folder of audio files for use as a DJ music source.

Use it to prepare music for Pioneer CDJ players, Denon SC6000 players, DJ controllers, or the AC Native dj piece.

It avoids manually formatting, labeling, and safely ejecting the stick before using it with DJ equipment.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00108	$0.02224
Opus 5.5	$0.00043	$0.00890
Sonnet 5.5	$0.00022	$0.00445

Security

Grade B, and why

dj-usb-maker scanned grade B with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

How it starts

The opening of the file, as written. The whole thing — 152 lines — stays where its author put it; the contents beside it link to each section on GitHub.

dj-usb-maker

You produce a USB drive that is dual-compatible with:

Traditional DJ hardware — Pioneer CDJ-2000/3000, Denon SC6000/Prime 4, Numark Mixstream, plus any DJ controller's USB-host port.
AC Native dj piece (fedac/native/pieces/dj.mjs) — auto-mounts the first non-boot USB to /media as vfat/exfat/ext4 read-only, then recursively scans up to 4 levels deep for audio files.

Both targets share the same sweet spot: FAT32, ASCII filenames, mp3/wav/flac at the root or one folder deep, no macOS metadata cruft. Default to that unless the user overrides.

How the AC Native dj piece reads a stick

From fedac/native/src/js-bindings.c (probe_mount_music_once) and fedac/native/pieces/dj.mjs:

Boot USB is detected (any /dev/sd? already mounted) and skipped, so the DJ stick must be a different physical device than the boot stick.
The first non-boot partition that mounts read-only at /media wins. Filesystem tried in order: vfat, exfat, ext4.
The piece walks /media, /mnt/samples, /mnt recursively (max depth 4), accepting these extensions: mp3, wav, flac, ogg, aac, m4a, opus, wma.
Dotfiles (.foo, ._foo) are excluded. macOS Finder cruft would just be wasted bytes — strip it.
Tracks are sorted alphabetically by filename. The filename is the on-screen track name (extension stripped). ID3 tags are not displayed yet, so name files for human reading.

Procedure

1. Gather inputs

Ask the user (via AskUserQuestion) for whatever isn't already in the prompt:

Source: a folder path containing audio. Accept the path verbatim — don't try to find files elsewhere. Resolve ~ to $HOME.
Target USB: list candidates with diskutil list external (macOS) or lsblk -d -o NAME,SIZE,TRAN,MOUNTPOINT,LABEL | grep -i usb (Linux). If exactly one external is plugged in, propose it; if zero, stop and tell the user to plug one in; if multiple, ask which.
Label: default ACDJ. If the user wants something else (e.g. MIXTAPE), accept any 1–11 char uppercase ASCII (FAT32 label limit).
Layout: default flat (mp3s in root, max CDJ compatibility). Offer "preserve folders" if the source has organized subdirs the user wants kept — AC Native walks 4 levels deep so up to that many nested folders is fine.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

dj-usb-maker is an agent published in the GitHub repository whistlegraph/aesthetic-computer (91 stars, last pushed yesterday), licensed ISC. It adds 108 tokens to every session and 2,224 once invoked, about $0.0004 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
