Start the editor outside the session and try again.\" It sits beside an existing refusal that applies when `CLAUDE_CODE_CHILD_SESSION` is set, which Claude Code sets for programs it starts itself.\n\n**Why**\n\nIf you see this message, start the editor from a normal terminal rather than from inside Claude Code, then sign in again.\n\n- Area: Claude Design\n- Names: `CLAUDE_CODE_CHILD_SESSION`\n- Tier: Under the hood\n- Useful: 2\/5\n- Signal: 4\/5"}
