A macOS plugin that converts QQ Music .ogg and .oggh audio files into .mp3 files while carrying over cover art and metadata. Metadata is information such as the song title, artist, and album.

Use it to convert QQ Music files on a Mac, preserve embedded cover art sourced from the file's resource data, and retain audio metadata through slash commands or natural-language requests.

It avoids manually converting files and then separately restoring their artwork and song details. The operations run without administrator privileges.

Security

Grade A, and why

ogg2mp3 scanned grade A with 0 findings 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 yesterday.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

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.
