Transcript
Now I have all the research I need. Here's the narration. Developers are burning $500 a month on AI coding agents. RTK is a free open-source CLI proxy that compresses command output before it hits your LLM, cutting token usage by 60 to 90% across over 100 commands. A typical 30-minute Claude code session drops from 118,000 tokens down to 24,000. That is an 80% reduction on Git, test, and build output with under 10 milliseconds overhead. Written in Rust, single binary, works with Claude code, Copilot, Cursor, Gemini, and six more tools. Over 21,000 stars on GitHub, link below. See you tomorrow.
