This mode only works for Claude Code sessions that Anthropic itself hosts; on any other client, the request still succeeds but silently falls back to `omitted` once the API rejects the value.\n\n- A tightened validation schema now requires `max_thinking_tokens` to be an integer or `null`, and `thinking_display` to be one of a fixed set of values or `null`, with a matching error message when the input doesn't fit.\n\n**Why**\n\nThe new display mode gives a more scannable view of Claude's thinking on supported sessions, while the stricter validation makes sure invalid values for these settings produce a clear error instead of being silently accepted.\n\n- Area: Thinking Display\n- Names: `set_max_thinking_tokens`, `highlights`\n- Tier: Use it now\n- Useful: 4\/5\n- Signal: 3\/5"}
