Tip: RTK (Rust Token Killer) Cuts Claude Code Token Consumption 60-90% — Single Binary, Zero Dependencies, 17K Stars

GitHub·high signal

RTK is a Rust CLI proxy that sits between your AI coding agent and the shell, intercepting command output and applying four compression strategies (smart filtering, grouping, truncation, deduplication) before tokens hit the context window. A typical 30-minute Claude Code session drops from ~150K to ~45K tokens. One user reported saving 10M tokens (89%) across sessions. Supports 10 AI coding tools (Claude Code, Cursor, Gemini CLI, Aider, Codex, Windsurf, Cline) with transparent shell rewriting. Sub-10ms overhead. For Max plan users burning through 5-hour windows, this effectively extends sessions 3x.
