Summary of Changes
Hello @MervinPraison, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!
This pull request focuses on improving the agent.py module's internal structure by extracting and consolidating common logic into reusable helper methods. The primary goal is to reduce code duplication and enhance maintainability by standardizing how chat messages are built and how tools are formatted for the LLM completion API. These changes are implemented in a backward-compatible manner, ensuring existing functionalities remain unaffected.
Highlights
- Code Consolidation: Introduced two new private helper methods,
_build_messages()and_format_tools_for_completion(), to centralize and standardize the logic for constructing chat messages and formatting tools, respectively. - Duplication Reduction: Replaced repetitive message building and tool formatting logic within the
chat(),achat(), and_chat_completion()methods with calls to the new helper methods, resulting in the removal of approximately 105 lines of duplicated code. - Maintainability Improvement: Aligned
agent.pywith existing patterns found inllm.pyto enhance code organization, improve readability, and simplify future maintenance efforts. - Backward Compatibility: Ensured that all changes are 100% backward compatible, with no breaking changes introduced to existing agent functionalities.
- New Test Coverage: Added a new dedicated test file,
test_agent_refactor.py, to thoroughly validate the functionality and backward compatibility of the refactored components.

Code Review
The code changes refactor agent.py to reduce code duplication by introducing the _build_messages and _format_tools_for_completion helper methods. The test file, test_agent_refactor.py, tests a copy of the new methods instead of the actual implementation in agent.py. There are opportunities to further reduce code duplication and improve clarity within the new helper methods. Some minor style issues were found in the test file.

834-886: Well-structured helper method for message building!The
_build_messagesmethod effectively consolidates the message construction logic, properly handling system prompts, chat history, JSON output requirements, and multimodal prompts. This refactoring improves code maintainability.
887-954: Comprehensive tool formatting implementation!The
_format_tools_for_completionmethod effectively handles all documented tool formats with proper validation and error handling. The nested dictionary validation and JSON serialization check add robustness.
1169-1170: Clean refactoring in _chat_completion!Good job replacing the inline tool formatting logic with the new helper method while preserving the explanatory comment.
1403-1404: Proper usage of _build_messages helper!The refactoring correctly uses the helper method and properly handles the returned
original_promptfor maintaining chat history.
1640-1641: Consistent refactoring in async method!The
achatmethod properly uses both helper methods, maintaining consistency with the synchronouschatmethod implementation.Also applies to: 1663-1664
src/praisonai/tests/unit/test_agent_refactor.py (2)
138-301: Comprehensive test coverage!The test suite thoroughly covers all scenarios for both helper methods:
- Various prompt formats (string, multimodal)
- System prompt and chat history handling
- JSON output modifications
- All tool format types
- Edge cases and error handling
- Backward compatibility validation
This provides confidence that the refactoring maintains the expected behavior.
303-327: Well-structured test execution!The main function provides clear test orchestration with informative output, making it easy to verify the refactoring success when run as a script.

SummaryI've successfully implemented the fixes requested from my code review: 1. Fixed Shallow Copy Bug
2. Reviewed Error HandlingAfter reviewing the error handling in
Changes CommittedThe fixes have been committed to the PR branch in commit The refactoring maintains full backward compatibility while fixing the critical shallow copy issue that could have caused unexpected behavior in production. |
- Added import copy to both agent.py and test file - Changed prompt.copy() to copy.deepcopy(prompt) to prevent mutation of original objects - Ensures nested dictionaries in multimodal prompts are not modified This fixes the issue where modifying item["text"] would mutate the original prompt objects.

835-886: Well-implemented message building consolidationThe
_build_messageshelper method successfully consolidates the message building logic and correctly usescopy.deepcopy()to avoid mutating the original prompt. The implementation properly handles system prompts, chat history, and JSON output modifications.Consider adding type hints to improve IDE support and documentation:
-def _build_messages(self, prompt, temperature=0.2, output_json=None, output_pydantic=None): +def _build_messages(self, prompt: Union[str, List[Dict]], temperature: float = 0.2, + output_json: Optional[Any] = None, output_pydantic: Optional[Any] = None) -> Tuple[List[Dict], Union[str, List[Dict]]]:src/praisonai/tests/unit/test_agent_refactor.py (3)
7-10: Remove unused imports to improve code cleanliness.The static analysis correctly identifies unused imports that should be removed.
-import asyncio import copy import logging -from typing import Dict, Any
52-57: Combine duplicate conditional branches for better maintainability.The logic for handling JSON output instructions is duplicated and can be consolidated.

4-4: LGTM: Required import for deep copy functionalityThe
copyimport is correctly added to support the deep copy functionality used in the new_build_messageshelper method.
1170-1171: LGTM: Clean refactoring with helper methodThe replacement of manual tool formatting with the
_format_tools_for_completionhelper method successfully reduces code duplication while maintaining the same functionality.
1404-1405: LGTM: Effective consolidation of message building logicThe replacement of manual message building with the
_build_messageshelper method successfully reduces code duplication while maintaining backward compatibility and the same functionality.
1641-1642: LGTM: Consistent refactoring across sync and async methodsThe replacement of manual message building with the
_build_messageshelper method in the async method maintains consistency with the synchronous version while reducing code duplication.
1664-1665: LGTM: Consistent tool formatting across methodsThe replacement of manual tool formatting with the
_format_tools_for_completionhelper method in the async method maintains consistency with other methods while reducing code duplication.src/praisonai/tests/unit/test_agent_refactor.py (6)
70-71: Excellent use of deep copy to prevent mutation issues.The implementation correctly uses
copy.deepcopy()to avoid the shallow copy bug mentioned in the PR objectives. This prevents unintended modification of the original prompt objects.
127-135: Proper JSON serialization validation with comprehensive error handling.The implementation correctly validates JSON serialization and handles errors by returning an empty list, which aligns with the consistent error handling approach described in the PR objectives.
139-187: Comprehensive test coverage for message building functionality.The test function thoroughly validates the
_build_messagesmethod across multiple scenarios including system prompts, chat history, JSON output, multimodal prompts, and disabled system prompts. This ensures the refactoring maintains all expected behaviors.
190-265: Thorough validation of tool formatting with edge cases.The test function excellently covers all tool formatting scenarios including string names, pre-formatted tools, mixed types, nested lists, invalid tools, and default agent tools. This comprehensive coverage ensures the refactoring handles all tool input formats correctly.
268-301: Strong backward compatibility validation.The test function validates that various combinations of prompts, tools, and output formats continue to work correctly after refactoring. This directly addresses the PR objective of maintaining 100% backward compatibility.
304-328: Well-structured test orchestration with clear reporting.The main function properly orchestrates all tests and provides comprehensive success/failure reporting. The summary clearly indicates what functionality was validated, supporting the refactoring goals.

🛠️ Refactor suggestion
Fix f-string issues and improve error handling consistency
The tool formatting consolidation is well-implemented but has a couple of issues to address:
- F-string issues: Lines 918 and 927 use f-strings without placeholders
- Inconsistent error handling: Malformed tools generate warnings but processing continues, while JSON serialization errors cause the entire tool list to be discarded
Apply this diff to fix the f-string issues:
- logging.warning(f"Skipping malformed OpenAI tool: missing function or name")
+ logging.warning("Skipping malformed OpenAI tool: missing function or name")
else:
- logging.warning(f"Skipping malformed OpenAI tool in list: missing function or name")
+ logging.warning("Skipping malformed OpenAI tool in list: missing function or name")Consider making error handling more consistent by either:
- Skipping individual malformed tools for both validation and serialization errors
- Or failing the entire operation uniformly for all error types
Add type hints for better IDE support:
-def _format_tools_for_completion(self, tools=None):
+def _format_tools_for_completion(self, tools: Optional[List[Any]] = None) -> List[Dict]:📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

🤖 Prompt for AI Agents
In src/praisonai-agents/praisonaiagents/agent/agent.py lines 888 to 954, fix the
f-string issues by removing unnecessary f-string syntax on lines 918 and 927
where no placeholders are used, replacing them with regular string literals.
Improve error handling consistency by ensuring that malformed tools detected
during validation or JSON serialization are handled uniformly—either skip only
the problematic tools without discarding the entire list or fail the entire
operation consistently. Additionally, add appropriate type hints to the
_format_tools_for_completion method signature and relevant variables to enhance
IDE support and code clarity.
