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 primarily addresses a critical bug in the Ollama integration that caused premature termination during sequential tool execution. I've introduced a more sophisticated mechanism to determine when an LLM response constitutes a final answer versus an intermediate acknowledgment, particularly for Ollama. This allows for multi-step tool use while also incorporating safeguards against infinite loops, improving the overall reliability and capability of the system when using Ollama models.
Highlights
- Sequential Tool Execution for Ollama: I've enabled Ollama models to perform multiple sequential tool calls within a single interaction, addressing an issue where they would prematurely terminate after the first tool execution.
- Intelligent Termination Logic: I've implemented a 'smart termination' mechanism for Ollama, where the tool summary is only generated and the loop terminated after a minimum of 5 iterations. This prevents infinite loops while ensuring sufficient sequential execution.
- Improved Final Answer Detection: I've introduced a new
_is_final_answermethod that intelligently differentiates between intermediate LLM responses (like tool acknowledgments) and true final answers, especially for Ollama, preventing early termination. - Broad Applicability: These improvements are applied consistently across both synchronous (
get_response) and asynchronous (get_response_async) methods, ensuring robust behavior regardless of the execution context. - Backward Compatibility: The changes are specifically scoped to Ollama provider logic, ensuring no impact on the behavior of other LLM providers.

Code Review
This pull request effectively fixes an issue where Ollama models would prematurely terminate sequential tool execution. The core change, which introduces an iteration count threshold before generating a tool summary, is a solid approach. The new _is_final_answer method is a good step towards more intelligent response handling.
My review focuses on improving the maintainability and readability of the new logic by addressing hardcoded values and patterns, which aligns with your own notes in the pull request description. These changes will make the code easier to understand and modify in the future.

This method can be improved for maintainability and performance. As noted in the PR description, this implementation is quite hardcoded.
Here are a few suggestions:
- The
acknowledgment_patternsandstatus_patternslists are recreated on every call. They should be defined as module-level or class-level constants (as tuples for immutability and performance). - The various length thresholds (
50,30,40,10) are magic numbers. They should also be defined as named constants to improve readability. response_text.strip()is called multiple times. It's more efficient to call it once and store the result.
Here is a suggested refactoring that applies these points:
if not response_text:
return False
stripped_response = response_text.strip()
if not stripped_response:
return False
response_len = len(stripped_response)
# If response contains tool calls, it's likely not a final answer
if has_tool_calls:
return False
# For Ollama, be more conservative about what constitutes a final answer
if self._is_ollama_provider():
# If we have recent tool results, check if this is just acknowledgment
if tool_results:
response_lower = stripped_response.lower()
# NOTE: These patterns and thresholds should ideally be class-level constants for performance and maintainability.
acknowledgment_patterns = (
"i'll", "let me", "now i'll", "next i'll", "i need to", "i should",
"executing", "calling", "running", "using the", "based on this",
"now let me", "let me now", "i will now", "proceeding to",
"moving to", "continuing with", "next step", "now that i have",
"tool executed", "function called", "result obtained", "got the result"
)
status_patterns = ("done", "completed", "finished", "successful", "ok", "ready")
# Check if response is primarily acknowledgment

# If it's short and contains acknowledgment patterns, likely intermediate
if response_len < 50:
return False
# If response is very short and we have tool results, likely intermediate
if response_len < 30:
return False
# Additional check: if response mainly contains status updates or simple confirmations
if (response_len < 40 and
any(pattern in response_lower for pattern in status_patterns)):
return False
# For other providers, maintain existing behavior

The value 5 is a magic number, which makes the code harder to understand and maintain. Consider defining it as a named constant at the class or module level, for example: OLLAMA_SUMMARY_ITERATION_THRESHOLD = 5.

Bug: Hardcoded Patterns Violate Dynamic Detection
The _is_final_answer method uses hardcoded acknowledgment_patterns and status_patterns lists, combined with fixed length thresholds (e.g., 50, 30, 40 characters), to determine if an LLM response is a final answer. This directly violates the user's explicit instruction to "dont make it hardcoded like this" and to "implement dynamically" for detecting tool usage, as these patterns were specifically cited as examples to avoid.

352-409: Well-designed method for differentiating final answers from intermediate responses.The
_is_final_answermethod provides intelligent logic to distinguish between intermediate tool acknowledgments and final answers, especially for the Ollama provider. The comprehensive list of acknowledgment patterns addresses the core issue.Consider combining the nested if statements for better readability:
- if self._is_ollama_provider(): - # If we have recent tool results, check if this is just acknowledgment - if tool_results: + if self._is_ollama_provider() and tool_results: + # If we have recent tool results, check if this is just acknowledgment- # Check if response is primarily acknowledgment - if any(pattern in response_lower for pattern in acknowledgment_patterns): - # If it's short and contains acknowledgment patterns, likely intermediate - if len(response_text.strip()) < 50: - return False + # Check if response is primarily acknowledgment + if any(pattern in response_lower for pattern in acknowledgment_patterns) and len(response_text.strip()) < 50: + # If it's short and contains acknowledgment patterns, likely intermediate + return False
1171-1176: Effective prevention of premature termination with iteration threshold.The iteration count check (>=5) successfully prevents the issue where Ollama would stop after the first tool call. This allows sequential tool execution as intended.
Consider making the iteration threshold configurable instead of hardcoding it:
+ # Add class constant or instance variable + OLLAMA_MIN_ITERATIONS_BEFORE_SUMMARY = 5 + # Special handling for Ollama to prevent infinite loops # Only generate summary if we're approaching max iterations or stuck in a loop - if self._is_ollama_provider() and iteration_count >= 5: + if self._is_ollama_provider() and iteration_count >= self.OLLAMA_MIN_ITERATIONS_BEFORE_SUMMARY:
352-409: Successfully addresses PR objectives with room for future enhancements.The implementation effectively resolves issue #940 by preventing premature termination in Ollama sequential tool execution. The changes maintain backward compatibility and provide smart termination logic as intended.
As mentioned in the PR objectives, a future enhancement could implement dynamic tool call detection based on multi-agent patterns rather than the current hardcoded acknowledgment phrases, making the solution more flexible and robust.

352-417: Well-structured tool chain analysis with minor improvements neededThe
_analyze_tool_chain_contextmethod provides comprehensive analysis of tool execution patterns. However, consider these improvements:
- Magic numbers: The confidence score calculations use hardcoded values (0.4, 0.3, 0.2, 0.1) that should be defined as named constants.
- Performance: The method creates a new list
context['tool_names']for each result, which could be optimized.Consider extracting the confidence calculation weights as class constants:
+ # Tool chain confidence weights + SEQUENTIAL_COMPUTATION_WEIGHT = 0.4 + DATA_PROCESSING_WEIGHT = 0.3 + SUCCESS_RATE_WEIGHT = 0.2 + MULTIPLE_TOOLS_WEIGHT = 0.1Then update the confidence calculation:

418-474: Response quality assessment is well-designedThe
_assess_response_qualitymethod provides a good approach to assessing response completeness. The logic for checking tool references, conclusion indicators, and numeric data is sound.The dynamic pattern matching for conclusion indicators is a good improvement over hardcoded patterns, and the quality scoring system provides reasonable heuristics for determining response completeness.
510-557: Excellent dynamic approach to final answer detectionThe
_is_final_answermethod successfully replaces hardcoded patterns with intelligent analysis. The integration of tool chain context and response quality assessment provides a robust solution to the original problem.This method effectively addresses the PR objectives by:
- Removing hardcoded acknowledgment patterns
- Using dynamic analysis based on tool execution context
- Maintaining backward compatibility with other providers
- Providing reasonable fallback behavior for edge cases
1311-1312: Proper integration of dynamic final answer detectionThe replacement of direct length checks with
_is_final_answercorrectly implements the intended fix for premature termination.This change ensures that the system uses intelligent analysis instead of simple heuristics to determine when to stop tool execution iterations.
1318-1324: Improved tool summary generation logicThe integration of
_should_generate_tool_summarywith dynamic analysis replaces the hardcoded iteration count check, which was the root cause of the premature termination issue.This change correctly implements the fix by:
- Using context-aware analysis instead of fixed iteration counts
- Maintaining the safety fallback to prevent infinite loops
- Allowing for more sophisticated tool call sequences
2062-2063: Consistent implementation in async methodThe async version correctly mirrors the synchronous implementation by using
_is_final_answerinstead of length-based checks.This maintains consistency between sync and async implementations while applying the same intelligent analysis approach.
2069-2075: Consistent async implementation of dynamic tool summary generationThe async method correctly implements the same dynamic analysis approach as the synchronous version.
This ensures that both sync and async tool execution flows benefit from the intelligent termination logic, addressing the original issue comprehensively.

🛠️ Refactor suggestion
Simplify conditional logic and extract magic numbers
The decision logic in _should_generate_tool_summary can be improved:
- Magic numbers: Values like 0.7, 0.5, 0.6, 0.4, and 7 should be named constants.
- Conditional logic: The consecutive if-elif statements can be simplified as suggested by static analysis.
Extract the threshold values as class constants and simplify the conditional logic:
+ # Tool summary generation thresholds
+ HIGH_CONFIDENCE_THRESHOLD = 0.7
+ MEDIUM_CONFIDENCE_THRESHOLD = 0.5
+ GOOD_QUALITY_THRESHOLD = 0.6
+ ACCEPTABLE_QUALITY_THRESHOLD = 0.4
+ MAX_ITERATION_THRESHOLD = 7

In src/praisonai-agents/praisonaiagents/llm/llm.py around lines 475 to 509, the
method _should_generate_tool_summary uses hardcoded magic numbers for confidence
and quality thresholds and has multiple if-elif conditions. Refactor by defining
these numeric thresholds as descriptive class-level constants and simplify the
conditional logic by combining related conditions with logical operators to
reduce redundancy and improve readability.
Summary
This PR fixes the issue where Ollama models would terminate after the first tool call instead of continuing with sequential execution.
Problem
The original issue was in the tool execution logic where
_generate_ollama_tool_summarywas being called immediately after the first tool execution, causing premature termination:get_stock_priceexecutes → returns "The stock price of Google is 100"_is_final_answercorrectly returnsFalse_generate_ollama_tool_summarywas called immediately → generates summarymultiplytool can be calledSolution
Added iteration count threshold before generating Ollama tool summary:
Key Changes
Test Results
All validation tests pass:
_is_final_answercorrectly identifies intermediate vs final responsesExpected Behavior
get_stock_price('Google')→ returns "100"_is_final_answerreturnsFalseiteration_count < 5→ skip summary generation, continue loopmultiply(100, 2)→ returns "200"Fixes #940
There are various solid way to find if tool call being used. dont make it hardcoded like this
search using multi agents to understand how to find if tool call is used. accordlgin implement dynamically
