Score: 6.8/10 (Innovation: 7, Technical: 6, Documentation: 8, Utility: 6)

context-tax is a CLI tool that analyzes Claude Code session transcripts to quantify the token overhead sent on every turn—MCP servers, skills, agents, memory files, and built-in Claude Code context—and identifies unused or unreachable items. It provides actionable fix commands and shareable receipts, filling a practical gap in MCP context optimization with a zero-dependency, privacy-conscious design.

Target audience: AI developers and Claude Code users
