ctxopt
One context config for Claude Code, Codex, Cursor & more
What it does
ctxopt gives your AI coding agent a map of your project instead of forcing it to re-read everything each session. Free, open-source config for Claude Code, Codex, Antigravity, and Cursor — measured on a real project (64.5% less context on exploration tasks), not marketing numbers.
Claude Code, Codex, Antigravity y Cursor gastan contexto — y dinero — releyendo tu proyecto en cada tarea. ctxopt les da lo que necesitan y nada más. Claude Code, Codex, Antigravity, and Cursor spend context — and money — re-reading your project on every task. ctxopt gives them exactly what they need, nothing more. Cada vez que le pides algo a tu agente de IA, tiene que releer buena parte de tu proyecto para entender de qué hablas. Mientras más grande el proyecto, más fácil es que revise información que no necesita para esa tarea puntual — y eso se paga en tokens. Every time you ask your AI agent for something, it has to re-read a good chunk of your project to understand what you mean. The…from projectone2020.github.io

I made OwnTime to balance between competing priorities in my life. The idea is based on two main influences: the concept of "roles" from "The 5 Choices" (2015), and my repeated failure to effectively implement time blocking due to the necessary flexibility in my role. The app allows you to define time budgets, which are not much more than a few mutually exclusive countdown timers. The UX is essentially that of a chess clock for an arbitrary number of players with configurable time. The whole point of the app is to kick you out of the running role/priority when its time is up.
