RTK: open-source tool compresses terminal output before the model — claims ~70% token savings

Developer @midudev highlights open-source RTK (github.com/rtk-ai/rtk): it intercepts terminal command output and compresses it before it reaches coding agents such as Claude Code, Cursor, Copilot, and Codex, claiming about 70% token savings with automatic operation. Aimed at cutting token cost from verbose shell/log context in agent loops.
