66.5% of My Claude Code Tokens Were Wasted. A 200-Line Wrapper Got Them Back.

66.5% of my Claude Code tokens were being spent on output I never needed to read in full. Over 7,172 commands, I watched 37.2M input tokens compress down to 12.5M, which is a number I had to re-check three times before I believed it. The piece of software responsible is 200 lines of glue sitting between my shell and the agent, and it cost me thirty seconds to install.
