Unclear Whether this gate is enabled for any accounts is unread; it isn't known when or for whom this sandbox explanation appears.

What

A new block of instructional text can be added to the system prompt that explains, in detail, what the sandbox (the restricted environment a session runs in) does and does not give access to: which directories, which network destinations, and which credentials are available. It tells the model to report when something it needs is missing rather than try to work around the sandbox's limits.

Why

This is controlled by a gate called tengu_elegant_ocean, and nothing is yet known about whether or how it is being turned on for any account, so it isn't possible to say whether or when this text is currently shown.

What has happened since
