Show HN: RTK – Simple CLI to reduce token usage in your LLM prompts (opens in new tab)

I built this small tool for my own use to reduce the number of tokens I send to LLMs (Claude Code, etc.). It’s just a simple utility to filter command outputs before they hit the context.

Here is what I’m getting with it so far:

I’m putting it out there in case it's useful to anyone else. It's written in Rust.

P.S. This is just a tool I built for my own needs and decided to share. If you have constructive feedback on the Rust code or the logic, I'd love to hear it. If it's not for you, that's totally fine too—no need for "angry" comments, just trying to be helpful!
