They have a public dataset of 6000, real world coding agent sessions. About 80% of them are Claude Code. Lots of cool analyses to be done on these.

I built Prism this morning. It runs a tiny 500M parameter LLM in your browser on a given piece of text and visualizes the entropy of the probability distribution computed for each …

After analyzing thousands of agent trajectories, we’ve seen all sorts of bizarre LLM quirks, this being one of them. Would love to hear other war stories also!

Pretty cool! Always struck me as odd that the IDE has largely remained single-player for 40 years.

That was an insane time. The pace was unreal. I remember Netscape 2.0 had at least 6-7 beta releases prior to the full release. And each one just dropped something massive and fund…

Super interesting how this arc has played out for Microsoft. They went from having this massive advantage in being an early OpenAI partner with early access to their models to larg…

The biggest omission that immediately stands out to me is: "provides a clear sense of direction". I've seen so many examples of teams and organizations that experience a lack of cl…

I do really like Tonkotsu :) But beyond that, we wanted a playful, accessible brand. We think dev tools (particularly ones like Tonkotsu) are consumer products and we didn't want t…

Forgot to mention that an interesting behavior we see emerging is “human as editor”: let the agents make several commits in a branch, and then the human does a single refinement pa…

Hey HN, I’m Derek, part of a small team of ex-Facebook engineers and designer building Tonkotsu. We strongly believe that the future of software development requires every develope…

Is it model quality or the CLI itself?

Cool, but at the same time, it feels overwhelming: so many different CLI or IDE tools, so many extension points. It will be fascinating to see how this all shakes out.

Really feels like computer use models may be vertical agent killers once they get good enough. Many knowledge work domains boil down to: use a web app, send an email. (e.g. recruit…

Fascinatingly deep study. It shows the hyperoptimization needed to build these businesses: from all the work needed to calibrate pricing for each country, to technical safeguards l…

I suspect there are many, many things for which chat is a great interface. And by positioning ChatGPT as the distributor for all these things, they get to be the new Google. But yo…

What a fun blast from the past! I fondly remember real-time at Waterloo. If nothing else, it taught you how to project-manage/time-manage so you could write a project of tens of th…

Just based on usage, I would assume js/ts would be very valuable as well. I see a lot of the same issues there and agree the core algos seem to apply generally. Very cool project!

LOL came here to say this exactly. Everyone LOVES war stories in my experience :)

This is pretty awesome! If it's built on tree-sitter, is it fair to assume it's generalizable across languages?
