Show HN: Agent Lens – Code assistant observability in VSCode (github.com)

Agent Lens has been announced as a new tool for Visual Studio Code that enhances observability of AI coding agents like GitHub Copilot and Claude Code. This innovative feature allows developers to track the performance and usage of custom agents, revealing crucial insights such as which agents are most active, token distribution across models, and the efficiency of agent handoffs. By visualizing session data directly within VS Code, Agent Lens provides a comprehensive dashboard that captures metrics on agent activity, tool calls, and caches used, empowering developers to optimize their workflows. The significance of Agent Lens lies in its ability to demystify the often opaque operations of AI coding agents. As developers increasingly rely on AI tools, understanding agent interaction and resource consumption becomes essential for enhancing productivity and ensuring effective code generation. With features like interactive visualizations of directed acyclic graphs (DAG) and timeline session replays, users can quickly identify unused agents or skills, making informed adjustments to improve overall efficiency. The installation is straightforward, requiring no complex configuration, and emphasizes the importance of local data privacy by only accessing files on the user's machine.
