the tricky bit is ensuring your inaccurate plain english statement is captured and formalized correctly as lean.

I’ve written a lot of Lean for economic modeling (so take this with the caveat that it’s not frontier-level mathematics research) but I think this problem is overstated. If you follow good engineering standards—keep primitives composable and design abstraction well—it’s not so hard to understand enough Lean to ensure the formalized statement is correct.
In part this is possible because mathlib is very well-designed and has a very good API (in no small part because they’re willing to make breaking changes all the time), so building on top of it makes life much easier.

What kind of economic modelling uses Lean?

do you have examples . i am fascinated by this

Interesting, but I don't see any licensing terms, which means I can't touch it in a commercial setting.

What commercial setting do you want to use a Lean theorem-proving agent in?
It's AI generated, so licensing terms are unenforceable.

Or, more accurately: it's not possible to apply copyright to generated code; if you don't release it, it's a trade secret, but if you do, people can use it how they please.

A terminal AI coding assistant with a built-in math formalization engine — describe a problem in plain language and it converts it into a Lean 4 theorem and attempts a formal proof.

Could you provide a practical example?

There is one in the quickstart:
mathcode -p "prove that the square of an even number is even"
so ' a problem' here is just preexisting math theorems ?

Maybe consider an integration with theoremdb.org?

To be clear, I am deep into auto-research, but hooking up slop to slop is just unlikely to produce anything valuable.
Value is in how maths is communicated: The process, frustrations, triumphs, etc.
We have to able to take generated formalizations from “it compiles” to “it is correct” before crystallizing them.

Do you have a formal proof of that?

Premises:
Garbage in implies garbage out (first principle of computer science)
The input is possibly, but not necessarily garbage (definition of slop)
By the standard methods of modal logic, it follows that it is possible that the output is garbage and therefore slop by definition. QED.

I am not sure of the premise. You can have a filter which takes garbage in and outputs the clean data from the garbage, a denoiser. Also your definition of slop is not specific to slop. Any input can be garbage, including this human sourced and thought comment.

Nevertheless, the proof is valid and easy to certify

sounds like an awesome project.
wish these project always start with an example. i dont care about quickstart or featurelist if i dont know what this is.

And doesn’t use as many tokens, at least for now.

I just replaced git clone with a script which fetches the README.md and sets of a fleet of agents to do a cleanroom reimplementation.
Lets me ignore the LICENSE.md file, and use how I want.
