Sandbox Execution ✓

Here are the sandbox execution logs prior to making any changes:

Sandbox passed on the latest main, so sandbox checks will be enabled for this issue.

Step 1: 🔎 Searching

I found the following snippets in your repository. I will now analyze these snippets and come up with a plan.

Step 2: ⌨️ Coding

• Modify dspy/signatures/field.py ✓ bfea033 Edit

Modify dspy/signatures/field.py with contents:
• Add a docstring to the `Field` class explaining that it is a more ergonomic datatype that infers prefix and desc if omitted.
• Add a docstring to the `__init__` method explaining that it initializes the Field instance with the given parameters. Document the parameters using the `:param` tag.
• Add a docstring to the `finalize` method explaining that it sets the prefix if it's not provided explicitly. Document the parameters and return value using the `:param` and `:return` tags.
• Add a docstring to the `__repr__` and `__eq__` methods explaining what they do.
• Add a docstring to the `InputField` and `OutputField` classes explaining that they are subclasses of `Field` and what they are used for.

Step 3: 🔁 Code Review

I have finished reviewing the code for completeness. I did not find errors for sweep/add_docstrings_to_signature.

🎉 Latest improvements to Sweep:

• We just released a dashboard to track Sweep's progress on your issue in real-time, showing every stage of the process – from search to planning and coding.
• Sweep uses OpenAI's latest Assistant API to plan code changes and modify code! This is 3x faster and significantly more reliable as it allows Sweep to edit code and validate the changes in tight iterations, the same way as a human would.
• Try using the GitHub issues extension to create Sweep issues directly from your editor! GitHub Issues and Pull Requests.
