It states that screenshot IDs expire a few minutes after being captured, so a screenshot should be uploaded right after it's taken. It also tells Claude not to reuse the ID from a failed upload, instead retaking the screenshot and retrying at most once, and never retrying after a user has declined. For files a user has attached, Claude is told to use `file_upload` instead.\n\n**Why**\n\nThis prevents Claude from misusing `upload_image` for the wrong kind of file and avoids repeated failed upload attempts with a stale or already-rejected screenshot ID.\n\n- Area: Chrome & Browser\n- Names: `upload_image`, `file_upload`\n- Tier: You'll notice\n- Useful: 2\/5\n- Signal: 1\/5"}
