  7. Haven't benchmarked it, but for agentic coding e.g. Claude Code I found this useful: https://github.com/rtk-ai/rtk

  13. To reduce token count on command outputs you can also use RTK [0] [0]: https://github.com/rtk-ai/rtk

    comment by alex7o · 2026-04-16 · in Claude Opus 4.7
  15. I find grep and common cli command spam to be the primary issue. I enjoy Rust Token Killer https://github.com/rtk-ai/rtk , and agents know how to get around it when it truncates too hard.

  18. Faced this too. Tried https://github.com/rtk-ai/rtk to compress cli output but some commands started failing and the savings were minimal. Ended up just being more deliberate about context size instead of adding more tooling on top
