It also includes a set of authorship details:\n\n- role\n\n- whether the artifact was co-written\n\n- whether its type is locked\n\n- whether it comes from outside your organization\n\nClaude Code uses these details to decide how the content is presented to Claude. The check that runs before an artifact is published presents its changes from the same details.\n\n**Why**\n\nThis changes how artifact content that may not be trustworthy is presented to Claude.\n\n- Area: Artifacts\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 3\/5\n- Scope: individual\n- Heads-up: no"}
