RTK

Judgement

What it is

Developer tool

What it does

A command-line wrapper that compresses and filters the output of common dev commands before an AI coding agent reads it, to cut LLM token use.

Adopt it when

You run Claude Code or similar agents heavily and token costs from verbose test, build or git output are a real expense.

Watch out

The project is under a year old, and filtered output can hide details the agent needed to diagnose a problem.
