The Token Compression Illusion: Why Im Skeptical of RTK

▤ Summary

The article argues that RTK’s token-compression claims are overstated and that its savings metrics do not translate into meaningful reductions in real LLM costs. It highlights the risk of silent failures when compressed CLI output loses important context without the agent noticing. It also says RTK lacks the task-success benchmarks needed to prove that compression improves outcomes rather than just shrinking prompts. The piece concludes that output compression belongs more in native tooling features than as a standalone product, especially if shell tools change their formatting.
