The source directory has been indexed, and a complex function in src/agent.c has been identified. The function agent_run() is quite complex, handling multiple steps including response processing, tool execution, and context management.
A suggested refactor is to break this function into smaller, more manageable functions:
• process_response(): Handles response parsing and decision-making.
• execute_tools(): Executes tools when indicated.
• handle_incomplete_response(): Manages incomplete responses and retries.
• finalize_response(): Finalizes and returns the accumulated response.
This modular approach improves readability, maintainability, and testability.
I will now generate a detailed refactor report and save it to 'refactor_report.md'.

5 - The `agent_run()` function is a core component responsible for orchestrating the agent's lifecycle, including message handling, API communication, error handling, and recursive task management. Its length and complexity hinder maintainability and readability.  |
| 5 + The `agent_run()` function is highly complex, handling multiple responsibilities such as response parsing, tool execution, context management, and response accumulation. Its length and nested logic make it difficult to read, maintain, and test.

11 - ### 1. `build_request()`  |
12 - - Purpose: Construct the JSON payload for the API request.  |
13 - - Benefits: Isolates request construction, making it easier to modify and test.  |
| 11 + ### 1. `process_response()` 
| 12 + - Parses the JSON response. 
| 13 + - Determines the next steps based on response content. 
| 14 + - Handles context overflow and retries. 
14 | 15
15 - ### 2. `process_response()`  |
16 - - Purpose: Handle the API response, including parsing, error detection, and extracting the choice.  |
17 - - Benefits: Separates response handling logic, simplifies main loop.  |
| 16 + ### 2. `execute_tools()` 
| 17 + - Executes tools when indicated by the response. 
| 18 + - Manages tool call results and message updates. 
18 | 19
19 - ### 3. `handle_tool_calls()`  |
20 - - Purpose: Manage execution of tool calls, including calling tools and integrating results.  |
21 - - Benefits: Encapsulates tool execution, improves clarity.  |
| 20 + ### 3. `handle_incomplete_response()` 
| 21 + - Checks if the response is incomplete. 
| 22 + - Initiates continuation requests if needed. 
22 | 23
23 - ### 4. `check_incomplete_response()`  |
24 - - Purpose: Detect if the response indicates incomplete work, triggering context shrinking.  |
25 - - Benefits: Isolates heuristic checks, makes main loop cleaner.  |
| 24 + ### 4. `finalize_response()` 
| 25 + - Finalizes the accumulated response. 
| 26 + - Cleans up resources. 
26 | 27
27 - ### 5. `perform_iteration()`  |
28 - - Purpose: Encapsulate one iteration of the agent loop, calling the above functions.  |
29 - - Benefits: Modularizes iteration logic, facilitates retries and control flow.  |
| 28 + ## Benefits 
| 29 + - Improved readability and maintainability. 
| 30 + - Easier to write unit tests for individual components. 
| 31 + - Clear separation of concerns.

31 - ## Rationale  |
| 33 + ## Implementation 
32 | 34
33 - This refactor aims to:  |
34 - - Enhance readability and maintainability.  |
35 - - Facilitate unit testing of individual components.  |
36 - - Simplify control flow and error handling.  |
| 35 + The implementation involves extracting code blocks from `agent_run()` into these functions, passing necessary context as parameters, and replacing the original code with calls to these functions. 
37 | 36
38 - ## Implementation  |
| 37 + This modularization will significantly enhance the code quality and facilitate future extensions or modifications. 
39 | 38
40 - The implementation will involve creating these functions in `src/agent.c` and replacing the main loop in `agent_run()` with calls to `perform_iteration()` until completion or error.  |
| 39 + --- 
41 | 40
42 - ---  |
43 -   |
44 - This plan will be executed in the next step.  |
| 41 + This proposal will be used as the basis for the refactoring process. 
The refactor proposal has been documented in 'refactor_report.md'. The suggested approach breaks down the complex agent_run() function into smaller, more manageable functions, improving readability, maintainability, and testability. If you need the detailed refactored code or further assistance, please let me know!
