Enter your response: ---------- user ----------
hi

We are working to address the following user request:

hi


To answer this request we have assembled the following team:

FileSurfer: An agent that can handle local files.
WebSurfer:
    A helpful assistant with access to a web browser.
    Ask them to perform web searches, open pages, and interact with content (e.g., clicking links, scrolling the viewport, etc., filling in form fields, etc.).
    It can also summarize the entire page, or answer questions based on the content of the page.
    It can also be asked to sleep and wait for pages to load, in cases where the pages seem to be taking a while to load.
Coder: A helpful and general-purpose AI assistant that has strong language skills, Python skills, and Linux command line skills.
Executor: A computer terminal that performs no other action than running Python scripts (provided to it quoted in ```python code blocks), or sh shell scripts (provided to it quoted in ```sh code blocks).
User: A huError processing publish message for User/8d19aae6-3888-4890-9cb2-dc14c5d22958

EOFError

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "/Users/gaganbansal/workspace/.venv-m1/lib/python3.13/site-packages/autogen_agentchat/agents/_user_proxy_agent.py", line 167, in on_messages

Here is an initial fact sheet to consider:

1. GIVEN OR VERIFIED FACTS
   - The specific request is simply "hi," which provides no specific facts or figures.

2. FACTS TO LOOK UP
   - None required, as the request does not provide any context or mention any factual information that would need verification or supplementation.

3. FACTS TO DERIVE
   - None, as there is no information given in the request to logically deduce further details or insights.

4. EDUCATED GUESSES
   - "hi" is a greeting, so the request could be interpreted as a casual initiation of conversation or inquiry.


Here is the plan to follow as best as possible:

Since the original request is simply "hi," which is a greeting, and does not specify any particular task or objective, here is a short bullet-point plan for addressing the request based on the available team members:

- User: Engage by responding to the greeting to establish further context or clarify any specific needs or questions.
  - "Hello! How can I assist you today?"

- WebSurfer: Remain on standby in case the User follows up with a request that involves needing information from the web.

- FileSurfer: Stand by if the User requires handling or accessing local files in any follow-up request.

- Coder: Be prepared to assist with any programming-related inquiries or tasks if they arise.

- Executor: Remain inactive unless directed by Coder to run a specific script.

This plan focuses on establishing communication and determining the next steps based on User input.
