The Token Compression Illusion: Why I'm Skeptical of RTK

The author argues that RTK (a token compression tool) oversells its benefits by claiming 60-90% savings that only reflect stripped terminal output, not actual API costs, while introducing critical risks including silent failures where compressed text loses semantic meaning without the AI knowing, and lack of rigorous accuracy benchmarks proving the tool actually improves task completion rates. The skepticism centers on RTK being a brittle, unmaintainable feature rather than a robust product, as major CLI tools could easily implement native compression flags, making RTK's advantage temporary and its use in production workflows operationally risky.
