- **Include units**: "Convert 100 kilometers to miles"
- **Provide context**: "Find the monthly payment for a $200,000 loan at 4.5% APR for 30 years"
- **Specify precision**: "Calculate ฯ to 10 decimal places"
#### โ **Avoid:**
- Vague requests: "Do some math"
- Missing parameters: "Calculate compound interest" (missing principal, rate, time)
- Ambiguous units: "Convert 100 degrees" (Celsius to Fahrenheit? Degrees to radians?)
#### ๐ง **Configuration Hints:**
- If you get "tool not available" errors, you may need to enable additional tool groups
- Use `health_check` to see which tools are currently available
- Check the configuration guide for enabling specific mathematical capabilities
