ctxopt

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

  Ctx – a /resume that works across Claude Code and CodexApr 2026 · github.com · ▲72

  ctx is a local SQLite-backed skill for Claude Code and Codex that stores context as a persistent workstream that can be continued across agent sessions. Each workstream can contain multiple sessions, notes, decisions, todos, and resume packs. It essentially functions as a /resume that can work across coding agents. Here is a video of how it works: https://www.loom.com/share/5e558204885e4264a34d2cf6bd488117 I initially built ctx because I wanted to try a workstream that I started on Claude and continue it from Codex. Since then, I’ve added a few quality of life…

  Talanoa▲346

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
