Peek Behind the Curtain: See Claude's Tools and Context in Real-Time

Ever wondered what's going on under the hood when you chat with Claude? We're used to these assistants just giving us answers, but the actual process—the tools they call, the context they consume—usually happens in a black box. What if you could watch it all unfold live?

That's exactly what Claude HUD does. It's a clever little project that gives you a real-time, visual heads-up display of Claude's inner workings. No more guessing; you get to see the gears turning as you interact.

What It Does

Claude HUD is a browser extension that overlays a transparent dashboard directly onto your Claude chat interface. While you're having a conversation, it shows you a live feed of every tool Claude uses—like code interpreters, web searches, or file readers—and, crucially, how much of its precious context window is being consumed by your conversation. It turns the opaque API calls into something you can see and understand at a glance.

Why It's Cool

The magic here is in the transparency. For developers, this isn't just a neat trick; it's a practical debugging and learning tool. You can finally answer questions like: "Why did that query take so long?" or "Is my prompt eating up all the context with unnecessary details?"

The implementation is straightforward and developer-friendly. It works by intercepting and visualizing the network traffic between your browser and Claude's backend, presenting the data in a clean, non-intrusive overlay. It demystifies the AI's process without getting in the way of your actual work.

For anyone building with or simply trying to understand LLM behavior, this kind of feedback is invaluable. It helps you craft more efficient prompts and understand the cost (in terms of context) of your interactions.

How to Try It

Getting started is simple. The project is open source on GitHub.

1. Head over to the Claude HUD repository.
2. Follow the installation instructions in the README. It typically involves cloning the repo and loading it as an unpacked extension in Chrome or Edge (developer mode).
3. Refresh your Claude chat window, and the HUD should appear.

There's no complex setup or authentication needed—it works directly with the standard Claude web interface.

Final Thoughts

Claude HUD is one of those tools that feels obvious once you see it. It addresses a subtle pain point for power users and developers who want more insight into their AI interactions. It's not about changing how Claude works, but about making its processes visible and, therefore, more understandable.

If you're regularly pushing the limits of context windows or trying to optimize your prompts for performance, this extension is worth a few minutes of your time. It turns abstract concepts like "tool use" and "context tokens" into something you can literally watch happen. In the world of AI, where so much is hidden, a little visibility goes a long way.
