Most people never notice. Every prompt goes into one bucket. Every sequence drafted. Every subject line tested. Every revision made. When that bucket fills up, the model starts cutting corners. Generic output. Forgotten instructions. Copy that feels like it was written on autopilot. There is a name for it: context rot. Two tools built specifically to fix it. Went straight to GitHub. Checked every fork. Found the dominant versions by star count. GSD: 65,000 stars. Oh My Claudecode: 37,000. 102,000 combined. Almost nobody in this community is using either. I had both installed before dinner. GSD structures what goes into Claude's context at each stage of your project. Instead of flooding the window with everything, it feeds Claude exactly what it needs, when it needs it. One command installs 68 global skills that activate automatically. Oh My Claudecode handles multi-agent orchestration. You describe the task. It splits the work across specialized agents and runs them in parallel. Automatically. Both free. Both open source. GSD: npx get-shit-done-cc@latest Oh My Claudecode: /plugin marketplace add https://github.com/Yeachan-Heo/oh-my-claudecode Jay built this community around test-iterate-improve. Most people apply that to sequences and subject lines. Almost nobody applies it to the AI layer itself. You have already felt the drop in quality on longer sessions. Now you have a name for it. And a fix. Ian Kirk
