Checks your CLAUDE.md files for token bloat and tells you exactly where you're wasting context window. Flags files over 2K tokens, finds duplicate lines, spots verbose patterns like "please make sure to", and catches code blocks that run too long. The real value here is the concrete fix suggestions for each issue, so you're not just staring at warnings wondering what to cut. Runs a Node.js analyzer against your current project and breaks down the savings potential section by section. If you've been hitting context limits or just want leaner instruction files, this gives you the audit you need. Can help you apply the fixes directly once you know what to change.
