RTK is an open-source CLI proxy that intercepts shell commands and compresses their output before it reaches an AI coding agent.
By filtering out boilerplate, progress bars, and irrelevant noise, it helps keep context windows focused and reduces token consumption for developer workflows.
- 01
Automatic hook interception for major AI coding agents
- 02
Command-aware filtering for over 100 commands
- 03
Recall system for retrieving full output on command failure
- 04
CLI analytics for tracking token savings
- 05
Single Rust binary with zero external dependencies
Open Source
Completely free and open-source under the Apache 2.0 license with no usage limits or paid tiers.
Best for
Developers using AI coding assistants who pay per token or face context window limits, particularly those running command-heavy tasks like builds, tests, and git operations.
Not ideal for
Users who primarily rely on chat-only assistants without tool-use capabilities, or those requiring a GUI-based interface for managing context.
A highly effective, zero-config tool for developers looking to optimize AI agent context and reduce token waste, provided the agent supports shell command interception.
Recent releases (v0.36.0-v0.37.0) added native support for Kilo Code and Google Antigravity, improved Windows native binary hook execution, and enhanced telemetry with quality metrics.
