Create a new multi-agent workflow for task orchestration and automation.
This endpoint allows you to define complex workflows that coordinate multiple
agents to perform sophisticated development and operational tasks.
**Workflow Creation Process:**
1. **Validation**: Validate workflow structure and step definitions
2. **Agent Verification**: Verify required agent specializations are available
3. **Dependency Analysis**: Analyze step dependencies and execution order
4. **Resource Planning**: Estimate resource requirements and execution time
5. **Storage**: Persist workflow definition for future execution
**Workflow Step Types:**
- `code_analysis`: Static code analysis and review
- `testing`: Test execution and validation
- `build`: Compilation and build processes
- `deployment`: Application deployment and configuration
- `documentation`: Documentation generation and updates
- `security_scan`: Security analysis and vulnerability assessment
- `performance_test`: Performance testing and benchmarking
- `data_processing`: Data transformation and analysis
**Advanced Features:**
- **Conditional Execution**: Steps can have conditions and branching logic
- **Parallel Execution**: Steps can run in parallel for improved performance
- **Error Handling**: Define retry policies and error recovery procedures
- **Variable Substitution**: Use variables and templates for flexible workflows
- **Agent Selection**: Specify agent requirements and selection criteria
- **Timeout Management**: Configure timeouts for individual steps and overall workflow
**Best Practices:**
- Keep steps focused and atomic for better reliability
- Use meaningful names and descriptions for clarity
- Include appropriate error handling and retry logic
- Optimize step ordering for performance and dependencies
- Test workflows thoroughly before production use
