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.\n\n**Why**\n\nPrograms that host Claude Code can now tell which tools publish artifacts.\n\n- Area: Artifacts\n- Tier: Under the hood\n- Useful: 1\/5\n- Signal: 2\/5\n- Scope: individual\n- Heads-up: no"}
