Show HN: Vibetime – see what you ship when coding with AI agents

Vibetime is an npm-installable CLI that wraps Claude Code, Codex, Gemini, Aster, and Opencode in the terminal and uses session hooks to track the Claude Code, Codex, Cursor, and ZCode desktop apps, printing a session summary with git commits, line changes, and files touched when each session ends. It requires no config, daemon, or account by default, stores data locally in ~/.vibe/, and reads only git metadata, with an opt-in GitHub-based leaderboard that ranks sessions by commits with meaningful changes.
