# Function: makeHarmonyAnalysisReasoningParser()

```ts
function makeHarmonyAnalysisReasoningParser(
  opts?: ReasoningParserOptions,
): ReasoningParserFn;
```

Defined in: [src/batteries/llm/chat\_common/reasoning\_parsers.ts:222](https://github.com/NHTIO/ADK/blob/v1.20260713.1/src/src/batteries/llm/chat_common/reasoning_parsers.ts#L222)

Parse gpt-oss Harmony chain-of-thought on the `analysis` channel:
`<|channel|>analysis<|message|>…<|end|>`. (The user-visible answer is the separate `final` channel;
