Show HN: Unbug – A free, automatic bug detector using GPT-3.5 on GitHub CI

Since you say you've found it invaluable for your own projects, can you explain why? What bugs has it found for you that you wouldn't immediately notice by running code or unit tests?

I ask because in the example, you ask it to find bugs in a script that immediately fails when you run it. So I'm not sure what the value add is here.

EDIT: For anyone else who is wondering, this is just:

system prompt:

    Find bugs in the user's code.
    - Format results as JSON like so:
     [{"line":1,"reason":"short reason", "type":"type"},...]
    - It is better to return an empty array than a mistake (not really a bug).

user prompt:

    Here is my code:

    ${source_code}

    JSON Result:

@funerr why would you even create this and post it here? Is it just to try to market your newsletter? Who do you think would look at this and be impressed?
