…issue This fix ensures that handoff tools can access the current user message during execution. Previously, chat_history was updated after the LLM call, causing handoffs to fail with "no specific task was provided" message. The fix adds the user message to chat_history before LLM processing in both: - Custom LLM path - Standard OpenAI client path This maintains backward compatibility while fixing the handoff functionality.

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 significantly enhances the Agent's internal chat history management by ensuring user prompts are recorded before LLM processing, preventing redundant entries, and introducing robust error handling with history rollback. These changes aim to improve the reliability and consistency of conversation flows within the agent.
Highlights
- Improved Chat History Management: User messages are now consistently added to the
chat_historybefore the LLM call, ensuring that subsequent handoffs or reflections have access to the complete conversation context. - Duplicate Message Prevention: New logic has been introduced to prevent the same user message from being added consecutively to the
chat_history, leading to cleaner conversation logs. - Multimodal Prompt Normalization: Prompt content is now normalized to extract text from multimodal prompts for consistent storage in
chat_history. - Robust Error Handling with History Rollback: Implemented mechanisms to store the
chat_historylength and roll back the history to its previous state if an LLM call fails or guardrail validation is unsuccessful, preventing corrupted conversation states. - Thread-Safety Note: A comment has been added to the
Agent's__init__method, advising on the non-thread-safe nature ofchat_historyand suggesting synchronization mechanisms for concurrent access.

Code Review
This pull request introduces important fixes for handoff functionality and adds robust error handling with chat history rollbacks. The changes are well-structured, particularly the addition of try...except blocks to ensure atomicity of chat operations. My review focuses on a few areas to further enhance the code's maintainability and correctness, including addressing some code duplication and ensuring the new error handling is applied consistently across both synchronous and asynchronous methods.
| normalized_content = prompt | ||
| if isinstance(prompt, list): | ||
| # Extract text from multimodal prompts | ||
| normalized_content = next((item["text"] for item in prompt if item.get("type") == "text"), str(prompt)) |
There was a problem hiding this comment.
When a multimodal prompt does not contain a text part, str(prompt) is used as a fallback. This results in a string representation of a list of dictionaries (e.g., "[{'type': 'image', ...}]"), which is not a meaningful text content for the chat history. A better fallback would be an empty string "" to signify the absence of text.
Additionally, this entire block of code for normalizing prompts and preventing duplicates (lines 1162-1173) is repeated in three other places in this file (lines 1229-1240, 1496-1507, and 1562-1573). To improve maintainability, consider refactoring this logic into a private helper method.

There was a problem hiding this comment.
This try...except...raise block appears to be redundant. The while True loop is already wrapped in an outer try...except block (lines 1247-1444) which is designed to catch all exceptions, perform a history rollback, and return None.
Any unhandled exception within the while loop will naturally propagate to the outer except block. This inner try...except that just re-raises the exception adds unnecessary nesting and can be removed to simplify the code.

There's an inconsistent use of prompt and original_prompt for display_interaction calls within the reflection loop. Here, prompt is used, but in other places (e.g., line 1283), original_prompt is used.
Since original_prompt is what's used for normalizing and storing in the chat history, it would be more consistent and correct to use original_prompt in all display_interaction calls to accurately reflect what the user sees and what is stored. This also applies to line 1393.

447-449: Good addition of thread-safety documentation.The note clearly warns users about potential race conditions and provides actionable guidance for handling concurrent access.
1159-1219: Well-implemented chat history management with rollback capability.The implementation correctly handles multimodal prompt normalization, prevents consecutive duplicate user messages, and ensures consistent rollback on failures. Note that the duplicate prevention only checks the last message, allowing the same user message after an assistant response, which appears to be intentional behavior.
1316-1403: Comprehensive self-reflection implementation with proper error handling.The implementation correctly handles both custom LLMs and OpenAI models, with appropriate JSON parsing and satisfactory status checking. The min/max reflection logic is well-implemented.
1439-1445: Excellent error handling with chat history rollback.The try-except wrapper ensures chat history consistency by rolling back to the initial state on any unexpected errors, preventing partial state updates.
1493-1554: Consistent async implementation with proper chat history management.The async version correctly mirrors the synchronous implementation's improvements, including rollback capability and guardrail validation.
1558-1729: Well-implemented async OpenAI client path with consistent patterns.The implementation maintains the same robust chat history management, duplicate prevention, and guardrail validation patterns as the synchronous version.
1173-1173: Rollback mechanism validation complete: chat_history is only modified by agent methods.

846-875: Address the multimodal prompt fallback issue.The fallback
str(prompt)on line 865 still results in a string representation of a list of dictionaries for multimodal prompts without text content, which is not meaningful for chat history. This creates the same issue identified in previous reviews.Apply this fix to use an empty string as fallback:

1162-1173: Improve fallback handling for multimodal prompts without text content.The current fallback

🛠️ Refactor suggestion
Extract duplicate normalization logic into helper method.
This prompt normalization logic is duplicated across multiple locations in the file. Consider extracting it into a private helper method to improve maintainability.
The same logic appears at:
- Lines 1162-1173 (custom LLM section)
- Lines 1229-1240 (OpenAI client section)
- Lines 1481-1492 (async custom LLM section)
- Lines 1547-1558 (async OpenAI client section)
Create a helper method like:
def _normalize_and_update_chat_history(self, prompt, chat_history_length):
"""Normalize prompt content and update chat history if not duplicate."""
normalized_content = prompt
if isinstance(prompt, list):
# Extract text from multimodal prompts
normalized_content = next((item["text"] for item in prompt if item.get("type") == "text"), "")
# Prevent duplicate messages
if not (self.chat_history and
self.chat_history[-1].get("role") == "user" and
self.chat_history[-1].get("content") == normalized_content):
# Add user message to chat history BEFORE LLM call
self.chat_history.append({"role": "user", "content": normalized_content})
return normalized_content🤖 Prompt for AI Agents
In src/praisonai-agents/praisonaiagents/agent/agent.py around lines 1229 to
1240, the prompt normalization and chat history update logic is duplicated in
multiple places. Extract this logic into a private helper method that takes the
prompt as input, normalizes it by extracting text from multimodal prompts if
needed, checks for duplicates in chat history, and appends the new user message
if not a duplicate. Replace all duplicated code blocks at lines 1162-1173,
1229-1240, 1481-1492, and 1547-1558 with calls to this new helper method to
improve maintainability.

Bug: Prompt Handling Inconsistency Causes Errors
The Agent.chat and Agent.achat methods inconsistently use prompt and original_prompt. Within the self-reflection logic, calls to _apply_guardrail_with_retry and display_interaction incorrectly use prompt (which can be a multimodal list). This causes type mismatches in guardrail validation (expecting a string for regeneration) and inconsistent display, as chat_history stores the normalized original_prompt content. original_prompt should be used consistently for these operations.
