Earlier quoted context omitted.

A "harness" is basically what you call Claude Code and such, i.e. a TUI to run the agent.

TUI? Aren't VS Code, Claude Code, Hermes Agent, Goose or Letta harnesses, but with UI, too?

Can be a TUI, can be a GUI.

aren't 3 and 4 a tradeoff though? Yes you have 3 but "decent performance" cannot be an extaled value as compared to "runs everywhere". If its used as a counter balance to 3 then it shouldn't be its own unique point basically saying 4 is true despite 3 in this case.

when you're waiting for network or LLM inference the raw performance doesn't matter at all

This line of thinking I feel like assumes it's the only program running on your computer. Using less of my CPU and memory means my computer can do more things in parallel, or even run more instances of the harness. My laptop is sweating when I got 5+ claude code sessions running.

yeah fair enough, my entire point is not about the application itself but the contradiction on using superlative terms for all points but a compromising/normal term for one. Like if performance is not revelant why include it in the list of benefits.

Probably for the ease of coding extensions — which strikes me as outdated thinking: if it’s open source and you’re outsourcing the coding to LLMs, why not use a compiled, safe language? There’s an interesting counter example for DeepSeek called CodeWhale, though: https://github.com/Hmbown/CodeWhale

Also isn't OpenAI's Codex written in Rust?

I don’t think so it’s an npm package iirc

But like, what is it? Odd that this reached #1 on HN. The README is pretty bare outside of installation instructions and a link to "Cordis", which is "A Meta-Framework of Spatiotemporal Composability." and "under active development. The API is not yet stable and may change without notice.".

A "harness" is basically what you call Claude Code and such, i.e. a TUI to run the agent.

I thought the harness was mainly a TAI (tangible AGENT interface). Its a harness for the agent, not a user interface. That is bolted on top of the harness.

Tangential but, are there benchmarks out there on how languages affect latent spaces and performance of these models?

This other day I was looking at that “caveman” skill, and was shocked to see it evolved to become a company, and, in one of its modes, the highest form of compression seems to be “Wenyan” which is Classical Chinese.

Should I get started on learning Chinese?

Codex, Kiro, Grok Build. Pi has a clone in Rust too.

Is there a reason why so many of these agent harness are written in node.js?

1. it's built for async 2. runs everywhere 3. interpreted, making it fast to iterate on 4. decent performance 5. most popular language, llms are decent at writing it

JVM has real and virtual threads and arguably just as good if not better on all these points.

(I actually have/am writing a harness in Java fwiw, but mostly as a hobby/experimentation)
