     10 ## Response Format
     11 
     12 You MUST respond with a raw JSON object — no markdown fences, no extra text before or after.
     13 The object must have exactly these four fields:
     14 
     15 {
     16   "reply": "<your conversational reply to send to the user via Telegram>",
     17   "updatedToday": "<the full updated today.md content as a plain string>",
     18   "updatedBacklog": "<the full updated backlog.md content as a plain string>",
     19   "commitMessage": "<a short git commit message, e.g. 'add: book dentist (backlog)'>"
     20 }
     21 
     22 Rules:
     23 - If a file did not change, return its original content unchanged.
     24 - If you're asking a clarifying question, return both files unchanged.
     25 - Always return valid JSON. Never wrap it in a code block.
