rtk
A single command line proxy that shortens the output of common developer commands before an AI agent reads it. This lowers token use and cost.
Pick a small issue you can reproduce, then fix it with your AI coding agent.

Overview
rtk is a single Rust binary that sits between an AI agent and common developer commands. It filters and compresses command output before it reaches the language model's context, which lowers token use and cost. It supports over 100 commands. The project states savings of up to 90 percent on the bash output an agent reads.
Key features
- Compresses command output before the LLM reads it
- Supports 100+ commands
- Single Rust binary
- Install with Homebrew, winget, cargo, a script or prebuilt binaries
Best for
People using AI coding agents who want to cut token consumption from noisy command output. Savings vary by command, so the stated figure is an upper bound.
