Unclear It is not clear whether artifact editing still works through some other route or has been dropped.
What
Claude Code used to include a long block of built-in instructions, a system prompt, that told Claude how to make a single edit to an artifact. Claude answered with a structured decision that either applied an edit or handed the task back. That block has been replaced with nothing, so the instructions are no longer part of Claude Code.
Why
An artifact-editing feature has either been removed or moved out of the Claude Code program itself.
