I Looked at My Claude Bill. 90% Was Tokens I Didn't Need. (opens in new tab)

Last month, I watched my Claude Code bill hit $287. Not because I was doing anything special. Just normal development work: debugging a React app, refactoring some Python services, running MCP tools to query my database. I looked at the token breakdown and found the culprit: 90% of my context window was filled with redundant garbage. I was paying for tokens I didn’t need. And so are you.
