Response format

[Raygama]

Create a module that format the response from the LLM into the one with emotion and the LLM text

• Define response schema: e.g. { "text": "...", "emotion": "neutral" }.
• Instruct LLM (via prompts) to output JSON.
• Implement parsing logic and fallbacks when the LLM misformats.
• Map emotion labels (string) using EmotionMapper.
