Claude Code now tracks which artifacts you created, per account and conversation, as 'own created'
When an artifact is created, Claude Code now records its slug (identifier) into a new session-state map called ownCreatedSlugs, tagged with the current environment. This only happens when the acting agent isn't the top-level agent-context-skip case, and when the account/conversation matches the one that made the create call. This tracking is separate from the existing roomStoppedByUser tracking.
This is internal bookkeeping that lets Claude Code know which artifacts were created by the current session itself, likely to support other logic that behaves differently for artifacts you created versus ones you didn't.
The finding doesn't say what consumes this new `ownCreatedSlugs` tracking or how it changes visible behavior.
