What
For a certain set of tools, Claude Code now attaches a marker saying the tool publishes an artifact, meaning it produces an output that is shared or saved beyond the chat. These tools still have their results kept when they run inside a subagent, which is a helper agent Claude starts to handle part of a task. The set of tools this applies to is now a different set from the one used before.
Why
Programs that host Claude Code can now tell which tools publish artifacts.
