feat: SWE Agent Implementation

[JayQuimby]

WIP: Implementing an agent that works similar to SWE-Agent

Agent Features:

• [x] Application Computer Interface - simplifies the commands required by the llm.
  • [x] Implement: 'read', 'write', 'browse', 'exit', 'edit', 'goto', 'scroll'
• [x] Think-Act prompting structure - guides the model to think about what its next step should be and then make code to do it
• [x] Short Term Memory - Allows the model to see it's last n steps before taking the next one
• [x] Tells the model about its current working dir, file, and line

Help / Suggestions:

• Open to other ideas people might have on how to improve this
• This agent should be similar to SWE agent, so I would appreciate ideas staying related to that
• Any help or additional code would be much appreciated

Agent/model	SWE-bench % resolved
SWE-Agent (GPT-4)	12.29%
Devin (25% of eval set)	13.84%
Claude 3 Opus (RAG)	3.79%
GPT-4 (RAG)	1.44%

Since SWE-Agent is so close to Devin in performance, I figure trying to emulate it and then iterate on it is the best route.
