What it does

100x-dev records the git HEAD when you start a session, then walks every commit since that point when you stop. It classifies each commit as AI-written or human-written by looking for Claude Code co-author tags, [AI]/[Claude] prefixes, and 🤖 annotations. It counts lines per author, computes a multiplier (totalLines / humanLines), and renders a session card in the terminal. Stats persist locally in ~/.100x-dev/sessions.json — no telemetry, no network calls.
