   * conversational turns with the `messages` parameter, and the model then generates
   * the next `Message` in the conversation. Consecutive `user` or `assistant` turns
   * in your request will be combined into a single turn.
   *
   * Each input message must be an object with a `role` and `content`. You can
   * specify a single `user`-role message, or you can include multiple `user` and
   * `assistant` messages.
   *
   * If the final message uses the `assistant` role, the response content will
   * continue immediately from the content in that message. This can be used to
   * constrain part of the model's response. This is called prefill. On models that
   * don't support prefill, creating a message that ends with a partial `assistant`
   * response returns a 400 error. See
   * [Prefill not supported](https://platform.claude.com/docs/en/api/errors#prefill-not-supported).
   *
   * Example with a single `user` message:
   *
   * ```json
   * [{ "role": "user", "content": "Hello, Claude" }]
   * ```
   *
   * Example with multiple conversational turns:

   *   { "role": "user", "content": "Can you explain LLMs in plain English?" }
   * ]
   * ```
   *
   * Example with a partially-filled response from Claude, for models that support
   * prefill:
   *
   * ```json
   * [
   *   {
   *     "role": "user",
   *     "content": "What's the Greek name for Sun? (A) Sol (B) Helios (C) Sun"
   *   },
   *   { "role": "assistant", "content": "The best answer is (" }
   * ]
   * ```
   *
   * Each input message `content` may be either a single `string` or an array of
   * content blocks, where each block has a specific `type`. Using a `string` for
   * `content` is shorthand for an array of one content block of type `"text"`. The

   * those tools using the tool input generated by the model and then optionally
   * return results back to the model using `tool_result` content blocks.
   *
   * There are two types of tools: **client tools** and **server tools**. The
   * behavior described below applies to client tools. For
   * [server tools](https://platform.claude.com/docs/en/agents-and-tools/tool-use/server-tools),
   * see their individual documentation as each has its own behavior (e.g., the
   * [web search tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool)).
   *
   * Each tool definition includes:
   *
   * - `name`: Name of the tool.
   * - `description`: Optional, but strongly-recommended description of the tool.
   * - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
   *   tool `input` shape that the model will produce in `tool_use` output content
   *   blocks.
   *
   * For example, if you defined `tools` as:
   *
   * ```json
   * [
   *   {
   *     "name": "get_stock_price",
   *     "description": "Get the current stock price for a given ticker symbol.",
   *     "input_schema": {
   *       "type": "object",
   *       "properties": {
   *         "ticker": {
   *           "type": "string",
   *           "description": "The stock ticker symbol, e.g. AAPL for Apple Inc."
   *         }
   *       },
   *       "required": ["ticker"]
   *     }
   *   }
   * ]
   * ```
   *
   * And then asked the model "What's the S&P 500 at today?", the model might produce
   * `tool_use` content blocks in the response like this:
   *
   * ```json
   * [
   *   {
   *     "type": "tool_use",
   *     "id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
   *     "name": "get_stock_price",
   *     "input": { "ticker": "^GSPC" }
   *   }
   * ]
   * ```
   *
   * You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
   * input, and return the following back to the model in a subsequent `user`
   * message:
   *
   * ```json
   * [
   *   {
   *     "type": "tool_result",
   *     "tool_use_id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
   *     "content": "259.75 USD"
   *   }
   * ]
   * ```
   *
   * Tools can be used for workflows that include running client-side tools and
   * functions, or more generally whenever you want the model to produce a particular
   * JSON structure of output.
   *
   * See our
   * [guide](https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview)

  tool_choice?: ToolChoice;

  /**
   * Body param: Definitions of tools that the model may use.
   *
   * If you include `tools` in your API request, the model may return `tool_use`
   * content blocks that represent the model's use of those tools. You can then run
   * those tools using the tool input generated by the model and then optionally
   * return results back to the model using `tool_result` content blocks.
   *
   * There are two types of tools: **client tools** and **server tools**. The
   * behavior described below applies to client tools. For
   * [server tools](https://platform.claude.com/docs/en/agents-and-tools/tool-use/server-tools),
   * see their individual documentation as each has its own behavior (e.g., the
   * [web search tool](https://platform.claude.com/docs/en/agents-and-tools/tool-use/web-search-tool)).
   *
   * Each tool definition includes:
   *
   * - `name`: Name of the tool.
   * - `description`: Optional, but strongly-recommended description of the tool.
   * - `input_schema`: [JSON schema](https://json-schema.org/draft/2020-12) for the
   *   tool `input` shape that the model will produce in `tool_use` output content
   *   blocks.
   *
   * For example, if you defined `tools` as:
   *
   * ```json
   * [
   *   {
   *     "name": "get_stock_price",
   *     "description": "Get the current stock price for a given ticker symbol.",
   *     "input_schema": {
   *       "type": "object",
   *       "properties": {
   *         "ticker": {
   *           "type": "string",
   *           "description": "The stock ticker symbol, e.g. AAPL for Apple Inc."
   *         }
   *       },
   *       "required": ["ticker"]
   *     }
   *   }
   * ]
   * ```
   *
   * And then asked the model "What's the S&P 500 at today?", the model might produce
   * `tool_use` content blocks in the response like this:
   *
   * ```json
   * [
   *   {
   *     "type": "tool_use",
   *     "id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
   *     "name": "get_stock_price",
   *     "input": { "ticker": "^GSPC" }
   *   }
   * ]
   * ```
   *
   * You might then run your `get_stock_price` tool with `{"ticker": "^GSPC"}` as an
   * input, and return the following back to the model in a subsequent `user`
   * message:
   *
   * ```json
   * [
   *   {
   *     "type": "tool_result",
   *     "tool_use_id": "toolu_01D7FLrfh4GYq7yT1ULFeyMV",
   *     "content": "259.75 USD"
   *   }
   * ]
   * ```
   *
   * Tools can be used for workflows that include running client-side tools and
   * functions, or more generally whenever you want the model to produce a particular
   * JSON structure of output.
   *
   * See our
   * [guide](https://platform.claude.com/docs/en/agents-and-tools/tool-use/overview)
   * for more details.
