# Usage Instructions
- Pass as a `system` message to `/chat/completions`. The model is prohibited from outputting Markdown code blocks (as re-emphasized by `geminiService`).
- Ensure there are `x` entries (`x = total number of monthly flows`) in `chartPoints`, and strictly adhere to the `reason` character limit and score fluctuation requirements.
