I have a fun little tool which runs the year-2000-era sloccount algorithm (which is Perl and C so I run it in WebAssembly) to estimate the time and cost of a project here: https://tools.simonwillison.net/sloccount
If you paste https://github.com/embedding-shapes/one-agent-one-browser into the "GitHub Repository" tab it estimates 4.58 person-years and $618,599 by year-2000 standards, or 5.61 years and $1,381,079 according to my very non-trustworthy 2025 estimate upgrade.
I pasted a subset of the Fil-C source code into your tool and it says 6 person years. I just pasted the compiler pass and the obvious parts of the runtime.
Note that I started the project in Nov 2023 and can only work on it maybe 1-2 hours a day because it's just a side project.
So I think your tool either estimates based on very bad programmers, or it's just wrong. Or maybe 10x programmers are real and I am him
These metrics necessarily have to underestimate programmer skills because those are not directly controllable. If there is any sort of rigor in these metrics (i.e. I don't know if COCOMO is one of them) they will probably assume, say, a mundane programmer whose performance is worse than 90/95/99% of all other programmers.
Here's more about the COCOMO model it uses: https://dwheeler.com/sloccount/sloccount.html#cocomo
Sounds like nonsensical pseudoscience
