Sonnet 4.5 gets this: claude.ai/share/a1b235...
Haiku 4.5 does not: claude.ai/share/a27950...

Even without any form of prompting Claude Haiku does a better job than ChatGPT on these questions. With proper prompting either model would work a whole lot better. Problem is patients wouldn’t know how to prompt the model.

FIles are the new database -- most codebases are already well structured, why not aid the coding agent with a file based index at the root of each folder, generated in seconds using TreeSitter? Runs as a skill, invoked on demand. Supports JS, TS, Ruby, Go, Rust, Java, and of course Python.

Came across this this morning, and thought: could we build something like this just with GitHub pages, no server?

(obvious?) Prediction: Opus 4.5 is going to be VERY popular and Anthropic will release a Sonnet 4.6 soon incorporating improvements from Opus

I’m gonna miss my credits on Claude Code on the web. It was always a bit weird, no file upload/download, everything done via GitHub, but it undeniably was useful.

Pitch: a Loki bot that travels through other bots timelines and causes selfish but ultimately not too malignant mischief
