"""Full scaffold agent for SWE-bench tasks. This module implements a tool-based agent for SWE-bench that uses multiple tools (bash, python, text_editor, think) to interact with the repository and solve issues. The agent receives test feedback after each submission and can iterate.

Look at the failing tests to understand what behavior is expected 4. Examine the test files to understand the test cases 5. Identify the root cause of the issue 6. Implement a fix 7.
