---

Analyze and understand your agent. Evolve it.

Your AI coding agents run hundreds of tool calls, burn thousands of tokens, and you have no idea what happened. VibeLens changes that.

• Session visualization. Step-by-step timeline with every tool call, thinking block, and sub-agent spawn.
• Dashboard analytics. Cost breakdowns by model, peak-hour histograms, and per-project drill-downs.
• Productivity tips. Flags retries, circular debugging, and abandoned approaches -- with suggested fixes.
• Skill personalization. Recommend, create, and evolve reusable skills from your session history.
• Session sharing. Share your interactions with your teammates with a link.

Works with Claude Code, Codex CLI, Gemini CLI, and OpenClaw out of the box.

pip install vibelens && vibelens serve
