RTK Token Killer
A failing vitest run is around 5,000 lines of output. The actual failure is 3 lines. Your AI coding tool read all 5,000.
RTK (Rust Token Killer) is a CLI proxy. Prefix rtk before any command and it strips the output to what the AI actually needs. That's the whole idea.
Here's what it cuts:
Tests (vitest, playwright): 90–99% Build output (Next.js, tsc, lint): 70–87% Git commands (status, log, diff): 59–80% Package manager output: 70–90%
I use it across all my game projects now. Sessions that used to stall halfway through a feature run to completion. The feature wasn't the problem. Twenty full build logs and eight complete test runs sitting in context were.
Run rtk discover on any recent session. It maps exactly where your tokens went.
Single binary. Zero dependencies. Works with Claude Code, Codex, Cursor, and 11 other tools. Drops into your workflow in under 5 minutes.
