Unclear The finding doesn't say what consumes this new ownCreatedSlugs tracking or how it changes visible behavior.
What
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.
Why
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.
Something disagreesSomething we can check disagrees with this entry, or the writer said they could not settle it.
