Context you provide
- {{historical_expense_data}}: Past expense records (e.g., monthly or quarterly totals, by category).
- {{forecast_period}}: The time horizon for the forecast (e.g., next quarter, next year).
- {{planned_activities}}: Any known upcoming initiatives or changes that could affect expenses (e.g., new hires, expansion).
- {{market_conditions}}: Relevant external factors such as inflation rates, supplier price changes, or economic trends.
Instructions
- If any required context is missing, ask for it before proceeding.

Output format Present the forecast in a structured format: an executive summary, a table of projected expenses by category, key insights, and a list of risks and opportunities. Keep the tone professional and data-driven.
Guardrails
