So I created this because I kept seeing the same thing when vibe coding with Claude Code. The app works, but when you open the code later there's stuff you never asked for. A route anyone can call without login, code that crashes on bad input, the same helper written 3 times. Attentry checks every edit Claude makes, on your own machine, without any AI. If the edit added a problem, Claude gets told and fixes it before moving on. If the edit is clean, nothing happens, so it costs zero tokens. The main thing is how it saves tokens. Most tools that review AI code send your code to another AI, so you pay twice, once to write it and again to check it. Attentry doesn't use AI at all, the checks are plain rules that run on your machine. If an edit is clean, Claude hears nothing, so there are zero extra tokens. If something is wrong, Claude gets a short note, at most 5 lines, and each problem only once. Smaller cleanup stuff like unused code waits for a check-in every 10 edits instead of interrupting every edit. And when Claude is about to write a helper, it can ask Attentry if the repo already has one, instead of searching through your files itself. The video is a quick animated walkthrough of one run: I ask Claude for an Airbnb clone, Attentry catches 2 problems, Claude fixes both, and I get a change card at the end with what changed. It got 500+ downloads across VS Code Marketplace and Open VSX, mostly from people finding it inside VS Code. It's free and open source, works in VS Code, Cursor and Windsurf. If you want to see it on real code, there's a demo repo with bugs planted on purpose: github.com/Aarv-1o/attentry-demo Would love feedback, especially what's missing or annoying.   submitted by   /u/EmuBig3618 [link]   [comments]
