[Feature Request] Implement a specialized agent for software engineering tasks

[libowen2121]

Required prerequisites

• [x] I have searched the Issue Tracker and Discussions that this hasn't already been reported. (+1 or comment there if it has.)
• [x] Consider asking first in a Discussion.

Motivation

The goal is to support software engineering tasks such as issue resolution, following benchmarks like SWE-Bench and SWE-Lancer. A typical workflow involves repository-level operations, including viewing, creating, deleting, and modifying code files, as well as executing bash commands. All actions should be executed within a sandboxed environment (e.g., Docker).

Solution

We propose integrating the CodeActAgent implementation from OpenHands, a general-purpose coding agent. More details on its functionality can be found in the CodeActAgent README.

To achieve this:

• Implement a new agent class, CodeActAgent, by inheriting from the BaseAgent class, using ChatAgent as a reference.
• Support execute_bash and str_replace_editor actions, as defined in the OpenHands implementation. Note that the implementation requests for these tools will be addressed in a separate issue.
• Integrate Docker runtime and support inference for a typical SWE like task instance (TBD).
