Usage Guidelines for Agents

When working with Alpha Vantage APIs:

Data Format: Prefer CSV over JSON when both formats are available
- CSV is more compact and easier to parse for tabular data
- Use
```
datatype=csv
```
  parameter in API requests
Response Handling: Always write API responses to files first
- Save responses to temporary or data files before processing
- Read from files with appropriate limits to avoid context burden
- Example: Use Read tool with
```
limit
```
  parameter to control data size
