CLI Agents API endpoints Hive API - CLI Agent Management Endpoints
Provides REST API for managing CLI-based agents in the Hive system.
This module provides comprehensive API endpoints for managing CLI-based AI agents
in the Hive distributed orchestration platform. CLI agents enable integration with
cloud-based AI services and external tools through command-line interfaces.
Key Features:
- CLI agent registration and configuration
- Remote agent health monitoring
- SSH-based communication management
- Performance metrics and analytics
- Multi-platform agent support

1. **Connectivity Validation**: Test SSH/CLI connection to target host
2. **Environment Verification**: Verify Node.js version and dependencies
3. **Model Availability**: Confirm AI model access and configuration
4. **Performance Testing**: Run baseline performance and latency tests
5. **Integration Setup**: Configure CLI agent manager and communication
6. **Health Monitoring**: Establish ongoing health check procedures
**Supported CLI Agent Types:**
- **Gemini**: Google's advanced AI model with reasoning capabilities
- **OpenAI**: GPT models for various specialized tasks
- **Claude**: Anthropic's Claude models for analysis and reasoning
- **Custom**: Custom CLI tools and AI integrations
**Configuration Requirements:**
- **Host Access**: SSH access to target machine with appropriate permissions
- **Node.js**: Compatible Node.js version for CLI tool execution
- **Model Access**: Valid API keys and credentials for AI service
- **Network**: Stable network connection with reasonable latency
- **Resources**: Sufficient memory and CPU for CLI execution
**Specialization Types:**
- `general_ai`: General-purpose AI assistance and reasoning
- `reasoning`: Complex reasoning and problem-solving tasks
- `code_analysis`: Code review and static analysis
- `documentation`: Documentation generation and technical writing
- `testing`: Test creation and quality assurance
- `cli_gemini`: Google Gemini-specific optimizations
**Best Practices:**
- Use descriptive agent IDs that include host and type
- Configure appropriate timeouts for network conditions
- Set realistic concurrent task limits based on resources
- Monitor performance and adjust configuration as needed
- Implement proper error handling and retry logic

Unregister and remove a CLI agent from the Hive cluster.
This endpoint safely removes a CLI agent by stopping active tasks,
cleaning up resources, and removing configuration data.
**Unregistration Process:**
1. **Task Validation**: Check for active tasks and handle appropriately
2. **Graceful Shutdown**: Allow running tasks to complete or cancel safely
3. **Resource Cleanup**: Clean up SSH connections and temporary resources
4. **Configuration Removal**: Remove agent configuration and metadata
5. **Audit Logging**: Log unregistration event for compliance
**Safety Measures:**
- Active tasks are checked and handled appropriately
- Graceful shutdown procedures for running operations
- Resource cleanup to prevent connection leaks
- Audit trail maintenance for operational history
**Use Cases:**
- Remove offline or problematic CLI agents
- Scale down cluster capacity
- Perform maintenance on remote hosts
- Clean up test or temporary agents
- Reorganize cluster configuration

Create and submit a new development task to the Hive cluster for execution.
This endpoint allows you to submit various types of development tasks that will be
automatically assigned to the most suitable agent based on specialization and availability.
**Task Creation Process:**
1. Validate task configuration and requirements
2. Determine optimal agent assignment based on specialty and load
3. Queue task for execution with specified priority
4. Return task details with assignment information
5. Begin background execution monitoring
**Supported Task Types:**
- `code_analysis`: Code review and static analysis
- `bug_fix`: Bug identification and resolution
- `feature_development`: New feature implementation
- `testing`: Test creation and execution
- `documentation`: Documentation generation and updates
- `optimization`: Performance optimization tasks
- `refactoring`: Code restructuring and improvement
- `security_audit`: Security analysis and vulnerability assessment
**Task Priority Levels:**
- `1`: Critical - Immediate execution required
- `2`: High - Execute within 1 hour
- `3`: Medium - Execute within 4 hours (default)
- `4`: Low - Execute within 24 hours
- `5`: Background - Execute when resources available
**Context Requirements:**
- Include all necessary files, paths, and configuration
- Provide clear objectives and success criteria
- Specify any dependencies or prerequisites
- Include relevant documentation or references

- Stop tasks that are no longer needed
- Cancel tasks that are taking too long
- Free up resources for higher priority tasks
- Handle emergency situations or system maintenance

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
