+ * User-facing interface for executing prompts with thinking block extraction.
+ *
+ * This interface provides thinking-aware versions of standard prompt operations,

+ * generated during their processing.
+ *
+ * ## Usage
+ *
+ * Access this interface through the `withThinking()` extension:
+ * ```kotlin
+ * val result = promptRunner.withThinking().createObject("analyze this", Person::class.java)
+ * val person = result.result // The converted Person object
+ * val thinking = result.thinkingBlocks // List of reasoning blocks
+ * ```
+ *
+ * ## Thinking Block Extraction
+ *
+ * This interface automatically extracts thinking content in various formats:
+ * - Tagged thinking: `reasoning here`, `content`
+ * - Prefix thinking: `//THINKING: reasoning here`
+ * - Untagged thinking: raw text content before JSON objects
+ *
+ * ## Relationship to Regular Operations
+ *
+ * Unlike [com.embabel.agent.api.common.PromptRunnerOperations] which returns
+ * direct objects, all methods in this interface return [ThinkingResponse]
+ * wrappers that provide access to both results and reasoning.
+ *
+ * @see com.embabel.agent.api.common.PromptRunnerOperations for standard operations
+ * @see ThinkingResponse for the response wrapper
+ * @see com.embabel.common.core.thinking.ThinkingBlock for thinking content details

+
+=== Working with LLM Reasoning / Thinking
+
+==== Motivation
+
+Sometimes user would like to validate LLM reasoning process in addition to getting back object.
+Imagine scenario: the user wants to plan a vacation and tells the LLM their preferred destinations are Greece and Italy and they can only take vacation in August, June, or September.
+Then the user asks the LLM to come up with some destinations with cheap plane tickets for a one-week stay.
+Let's say the output is a proper object, basically a round trip flight. Even if the output adheres to the schema,
+user wants to be able to verify whether the flight dates are in the requested months, and whether the destinations are in Greece/Italy vs somewhere else like Spain or Turkey.
+If flight details are outside user's criteria, user would like to be able to understand LLM reasoning process.
+
+Another use case even more important, when LLM is not able to fulfill request, in other words LLM is not able to
+create object in the very first place, since user's criteria is ambiguous.
+
+==== Concepts
+
+- ```ThinkingBlock``` - abstraction that carries details on LLM reasoning, including Tag type, Tag value, and LLM reasoning text
+- ```ThinkingTags``` - reasoning Tag Types and XML tags definition. Dynamic tags got supported as well
+- ```ResponseWithThinking``` - LLM response holder, wraps Object and List of ```ThinkingBlocks```
+- ```ThinkingException``` - wraps Thinking Blocks in case Object cant be instantiated
+- ```withThinking``` - Core ```PromptRunner``` API
+
+
+==== Example on handling Object and Thinking Blocks
+[source,java]
+----
+
+ // Use the LLM configured for thinking tests
+ PromptRunner runner = ai.withLlm("claude-sonnet-4-5")
+ .withToolObject(Tooling.class);
+
+ String prompt = "Think about the coldest month in Alaska and its temperature. Provide your analysis.";
+
+ //Use builder for natural chaining
+ ThinkingResponse response = runner
+ .withThinking()
+ .createObjectIfPossible(prompt, MonthItem.class);
+
+
+ MonthItem result = response.getResult();
+
+ List thinkingBlocks = response.getThinkingBlocks();
