RTK: Open-Source CLI Proxy Compresses Terminal Noise for AI Coding Agents
thetripathi58 · x · 2026-07-26
AI coding agents often waste context tokens reading noisy terminal outputs from commands like git status or pytest. RTK, an open-source CLI proxy written in Rust, intercepts shell commands and compresses their output before the agent reads them.
Core Features & Mechanism:
- Interception: Acts as a proxy to intercept shell commands, compressing the output intelligently.
- Four Strategies: Smart filtering, grouping, truncation, and deduplication.
- Command-Specific Optimization: E.g., pytest shows only failures, grep groups matches by file.
Performance & Compatibility:
- Supports 100+ commands with less than 10ms overhead.
- Works with Claude Code, Cursor, Windsurf, and other shell-running agents.
- Installs in one line and hooks into agents automatically.
