fix: PyLint Issue Fix

[Abdul-Microsoft]

Purpose

This pull request focuses on cleaning up unused imports and simplifying code across multiple files in the backend, specifically in agent-related modules and utility tools. The changes aim to improve code readability, reduce clutter, and ensure compatibility with updated dependencies. Below is a summary of the most important changes grouped by theme:

Removal of Unused Imports and Simplifications

• Removed unused imports such as semantic_kernel, KernelArguments, and other redundant dependencies across multiple files, including app_config.py, app_kernel.py, and various agent files (e.g., agent_base.py, human_agent.py) to streamline the codebase. [1] [2] [3] [4]

• Simplified type hints and removed unused type annotations (e.g., Any, Awaitable, Callable) in files like agent_factory.py, generic_tools.py, and marketing_tools.py. [1] [2] [3]

Updates to Agent and Tool Classes

• Removed redundant or commented-out code in agent classes such as HumanAgent, PlannerAgent, and MarketingTools, including unused methods and variables like param_desc in JSON documentation generation. [1] [2] [3]

• Adjusted logging and event tracking messages in HumanAgent to use consistent string formatting. [1] [2]

Compatibility and Dependency Updates

• Removed fallback import logic for older versions of semantic_kernel in config_kernel.py to align with updated library structures.

Minor Code Refinements

• Replaced unnecessary variable assignments (e.g., init_result) with direct calls to simplify asynchronous initialization in agent_factory.py.

These changes collectively enhance the maintainability and clarity of the backend codebase.
