Sustn, Turn unused Claude Code tokens into PRs that clean your codebase

Hi HN! I use Claude Code a lot, but my token usage is directly proportional to how long I'm willing to sit there prompting it. If I'm not at my desk thinking up tasks and feeding them in, the tokens just go unusued[which i weirdly feel bad about].

over the past couple of days, I hacked on sustn, a tool that scans your repo, figures out what needs fixing on its own (dead code, missing tests, security issues, etc.), and puts it in a prioritized list. Then it just starts working through the list - whether you're there or not.

When it's done with a task, it either creates a PR automatically or waits for your approval - you choose. You can reorder the list to control what gets picked up next, set a schedule (e.g let it run overnight), set a token budget, and add your own tasks manually too.

It runs on your local Claude Code instance, so nothing leaves your machine. Free and open source - https://github.com/Ghvstcode/sustn Still very early but would love feedback.
