Compressing chat messages to save tokens sounded clever until it started blowing up my prompt cache and mangling diffs.
Notes on code, chess, mistakes, and the tools I build with.
I'm Sushanth, a high school senior in Hyderabad, India. This is where I write about the things I spend time on: learning from mistakes, building things in code, and the tools I actually work with day to day. I hold the Candidate Master title and a FIDE International Master norm, earned across roughly 140 rated tournaments in six countries. I stopped competing in 2025, but the habit competition taught me, sitting down after every loss and figuring out exactly where I went wrong, shapes how I approach everything else. On the technical side, I've gone deep on C/C++ through Duke University and University of London coursework. I'm also someone who likes a good terminal workflow and enjoys exploring (and abandoning) productivity tools. Expect posts on Neovim, tmux, what broke this week, and whatever I'm tinkering with.
