Would be good to also unify the exception handling across all hooks, but not super pressing
…ation - Added decorators for before and after LLM and tool calls to enhance flexibility in modifying execution behavior. - Implemented a centralized hook registration mechanism within CrewBase to automatically register crew-scoped hooks. - Removed the obsolete base.py file as its functionality has been integrated into the new decorators and registration system. - Enhanced tests for the new hook decorators to ensure proper registration and execution flow. - Updated existing hook handling to accommodate the new decorator-based approach, improving code organization and maintainability.
- Introduced functions to unregister specific before and after hooks for both LLM and tool calls, improving flexibility in hook management. - Added clear functions to remove all registered hooks of each type, facilitating easier state management and cleanup. - Implemented a convenience function to clear all global hooks in one call, streamlining the process for testing and execution context resets. - Enhanced tests to verify the functionality of unregistering and clearing hooks, ensuring robust behavior in various scenarios.
- Updated hook type definitions to use generic protocols for better type safety and flexibility. - Replaced Callable type annotations with specific BeforeLLMCallHookType and AfterLLMCallHookType for clarity. - Improved the registration and retrieval functions for before and after hooks to align with the new type definitions. - Enhanced the setup functions to handle hook execution results, allowing for blocking of LLM calls based on hook logic. - Updated related tests to ensure proper functionality and type adherence across the hook management system.
