Commands

Every command the mod adds, what it prints, and where it works.

Everything the mod adds lives under /vbf, and typing it on its own prints a short list of the common ones. They are client commands, so they never reach a server and work anywhere the mod is loaded.

Getting in and out of an account

/vbf linkAnywhere
Links this installation to your Fragments account through the browser.Prints a link and a code, then waits up to twelve minutes. Walked through in linking your account.
/vbf link unlinkAnywhere
Signs this installation out of your account.Clears the credentials on this machine. You can still join worlds afterwards; you cannot create or promote one.
/vbf statusAnywhere
Prints what mode you are in, who you are, and what your session is doing.The first thing to run when something is behaving oddly, and the thing to paste into a bug report.

Worlds and the people in them

/vbf invite [days]Inside a Fragment· Owner or op

/vbf join <code>Inside a Fragment
Redeems an invite code, making you a member of that world.You still need that world's link to enter it.

Mods

/vbf packAnywhere
Shows which of this world's mods you are missing.Opens the same screen the join used. With nothing missing it says so in one line.
/vbf updateAnywhere

Privacy and your data

/vbf data exportInside a Fragment
Saves everything we hold about you into a file in your game folder.Needs a live session with us, which is why it wants a world.
/vbf data deleteAnywhere
Tells you how erasure is done, which is not from chat.

Telling us something is wrong

/vbf bug-report <text>Anywhere

What some of them print

You type/vbf sharelink

[VBF] your Fragment link: vbf:frag-brisk-otter-cedar-lantern

[VBF] friends paste this into Multiplayer → Add Server. It never changes.

An invite code

You type/vbf invite 14

[VBF] invite: FROSTY-BADGER-14 — expires in 14d

[VBF] share with friend: /vbf join FROSTY-BADGER-14

A refusal

VBF: whitelist add failed (403) — only the world owner can change the whitelist.

Role checks happen at our end, so the reason comes back in the message.

Things that look like commands and are not for you

Anything beginning /vbf-dev is for development and debugging. One of them is named in a message you may genuinely see: if the mod hands your simulation work to a peer because your connection was saturated, it tells you how to take it back. That is covered in when something is wrong.
