## Steps

### Step 0: Confirm Context

Ask the user for any missing context needed to produce a useful output. If the request is clear, skip questions and proceed.

### Step 1: Gather Context

Gather the target variable, time granularity, forecast horizon, and any known external factors (holidays, promotions, seasonality). Ask for data sample or schema.

### Step 2: Produce Output

Output a forecasting plan: recommended model stack (baseline → candidate → final), feature engineering steps, validation approach, and implementation code or pseudocode.

### Step 3: Summary

Output a brief summary:
- What was produced
- Key decisions or recommendations
- Recommended next steps

## Key Rules

- Follow the output format defined in docs/output-kit.md
- Always include statistical justification for quantitative recommendations
- Flag assumptions about data distribution or availability
