284 You should see `thinking` and `tool_use` blocks in the response content on a run that includes thinking (on simpler requests, adaptive mode may skip the thinking block). A note Claude writes before the tool call comes back as a `text` block or, on models that write [progress updates](https://platform.claude.com/docs/en/build-with-claude/thinking#progress-updates), as another `thinking` block. Keep this content array intact: the next step sends it back verbatim.

287287 To see thinking text like this output, add `display: "summarized"` to the request. On models where display defaults to omitted, including Claude Opus 5.5, the `thinking` field otherwise comes back as an empty string with only the `signature` populated. Either way, echo the content array back unchanged; see [Controlling thinking display](https://platform.claude.com/docs/en/build-with-claude/thinking#controlling-thinking-display).

751751 You should see Claude complete the turn with text. Because [interleaved thinking](https://platform.claude.com/docs/en/build-with-claude/thinking#interleaved-thinking) is automatic in adaptive mode, the continuation can also open with a new thinking block before the final text:
