# Agentic Structured Outputs
# :material-code-json: Agentic Structured Outputs
Structured outputs help ensure that your agents return data in a consistent, predictable format that can be easily parsed and processed by your application. This is particularly useful when building complex applications that require standardized data handling.
!!! abstract "Overview"
Structured outputs help ensure that your agents return data in a consistent, predictable format that can be easily parsed and processed by your application. This is particularly useful when building complex applications that require standardized data handling.
## Schema Definition
## :material-file-document-outline: Schema Definition
Structured outputs are defined using JSON Schema format. Here's the basic structure:
```python
tools = [

tools = [

### :material-format-list-bulleted-type: Parameter Types
The following parameter types are supported:
- `string` : Text values
- `number` : Numeric values
- `boolean` : True/False values
- `object` : Nested objects
- `array` : Lists or arrays
- `null` : Null values
| Type | Description | Example |
|------|-------------|---------|
| `string` | Text values | `"Hello World"` |
| `number` | Numeric values | `42` , `3.14` |
| `boolean` | True/False values | `true` , `false` |
| `object` | Nested objects | `{"key": "value"}` |
| `array` | Lists or arrays | `[1, 2, 3]` |
| `null` | Null values | `null` |

Follow these steps to implement structured outputs in your agent:
### Step 1: Define Your Schema

tools = [

"function": {
@ -55,53 +101,62 @@ The following parameter types are supported:

}
},

}
}
}

```
2. **Initialize the Agent**
```python
from swarms import Agent
### Step 2: Initialize the Agent
agent = Agent(
```
from swarms import Agent
agent = Agent(
agent_name="Your-Agent-Name",
agent_description="Agent description",
system_prompt="Your system prompt",
tools_list_dictionary=tools
)
```
3. **Run the Agent**
```python
response = agent.run("Your query here")
```
4. **Parse the Output**
```python
from swarms.utils.str_to_dict import str_to_dict
)
```
parsed_output = str_to_dict(response)
```
### Step 3: Run the Agent
## Example Usage
```python
response = agent.run("Your query here")
```
Here's a complete example using a financial agent:

## :material-check-circle: Best Practices
!!! success "Schema Design"
- **Keep it simple** : Design schemas that are as simple as possible while meeting your needs
- **Clear naming** : Use descriptive parameter names that clearly indicate their purpose
- **Detailed descriptions** : Include comprehensive descriptions for each parameter
- **Required fields** : Explicitly specify all required parameters
!!! info "Error Handling"
- **Validate output** : Always validate the output format before processing
- **Exception handling** : Implement proper error handling for parsing failures
- **Safety first** : Use try-except blocks when converting strings to dictionaries
!!! performance "Performance Tips"
- **Minimize requirements** : Keep the number of required parameters to a minimum
## Best Practices
- **Appropriate types** : Use the most appropriate data types for each parameter
1. **Schema Design**
- Keep schemas as simple as possible while meeting your needs
- Use clear, descriptive parameter names
- Include detailed descriptions for each parameter
- Specify all required parameters explicitly
- **Caching** : Consider caching parsed results if they're used frequently
2. **Error Handling**
- Always validate the output format
- Implement proper error handling for parsing failures
- Use try-except blocks when converting strings to dictionaries
## :material-alert-circle: Troubleshooting
3. **Performance**
- Minimize the number of required parameters
- Use appropriate data types for each parameter
- Consider caching parsed results if used frequently
!!! warning "Common Issues"
## Troubleshooting
### Invalid Output Format
Common issues and solutions:
!!! failure "Problem"
The agent returns data in an unexpected format
1. **Invalid Output Format**
- Ensure your schema matches the expected output
- Verify all required fields are present
- Check for proper JSON formatting
!!! success "Solution"
2. **Parsing Errors**
- Use `str_to_dict()` for reliable string-to-dictionary conversion
- Validate input strings before parsing
- Handle potential parsing exceptions
- Ensure your schema matches the expected output structure
3. **Missing Fields**
- Verify all required fields are present in the response
- Check for proper JSON formatting in the output
### Parsing Errors
!!! failure "Problem"
Errors occur when trying to parse the agent's response
!!! success "Solution"
```python
from swarms.utils.str_to_dict import str_to_dict
try:
parsed_data = str_to_dict(response)
except Exception as e:
print(f"Parsing error: {e}")
# Handle the error appropriately
```
### Missing Fields
!!! failure "Problem"
Required fields are missing from the output
!!! success "Solution"
- Verify all required fields are defined in the schema
- Check if the agent is properly configured
- Review the system prompt for clarity
- Check if the agent is properly configured with the tools
- Review the system prompt for clarity and completeness
