Rust binary, zero runtime deps. Claims large cuts on noisy command output so coding agents spend less context on `git status`, logs, and build spam. Homebrew formula; docs/troubleshooting at rtk-ai.app. Drop under existing agent shells without changing the agent product.","theCatch":"Vs the coding agent itself (Claude Code, Codex, Aider): RTK is a token-thrift layer under agents — output compression/proxy, not an agent, not a model router. You must wire it into the shell path the agent actually uses; over-aggressive filtering can hide the error you needed.","verdict":"Apache-2.0 agent shell thrift.
