Claude Code v2.1.251 28 Aug 2026

Artifacts owned by an agent are explained as not private

You'll notice

Useful2 Signal3

Artifacts

An artifact owned by an agent now says everyone with access to that agent can see it.

What

The share-status view for an artifact that belongs to an agent rather than a person now says so, notes that everyone with access to that agent can see it, and describes how a person can share it more widely.

Details

Informational copy only; it does not change who can reach the artifact.

Evidence

This artifact belongs to an agent rather than a person

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
