Running a few Claude Code sessions at once is great until I forget which one is doing what.

One is working through a change. Another has subagents running. A third might be waiting for me, but I won't know until I check that terminal again.

I kept bouncing between them to answer a few basic questions: What's happening? Does anything need me? Is the work actually finished?

That's why I built AgentMon Live.

It's a Claude Code mod that lets you watch Claude and its subagents work, see costs and usage limits, and spot when something needs your attention. It also checks for unfinished work before Claude says "done".

I shared an earlier release recently. This update adds the part I've been most excited about: you can now follow your agents live in your browser.

A browser view across your sessions

You keep working in Claude Code as usual. Open the browser view alongside it, and you can follow agent activity in real time and switch between sessions running in different terminals.

For my workflow, that last part matters a lot. Checking on several sessions means remembering where each one lives, switching terminals, and finding the relevant output. Having a browser view gives me somewhere to look while the work carries on.

The pane beside the chat is still available too. If you're working in one session, you might prefer keeping everything together. When several sessions are going, the browser gives you another way to follow them.

It's a simple addition to describe, but it's the one I've really wanted to use myself.

What I want to know while an agent works

Seeing activity is useful. Knowing when to pay attention is more useful.

AgentMon brings together running tool calls, subagent activity, changed files, and verification results. It also shows costs and how close you are to your usage limits.

That helps with the questions I keep coming back to:

  • What is Claude working on right now?
  • What are its subagents doing?
  • Is anything waiting for my attention?
  • How much of my usage allowance is left?
  • What has actually been checked?

I want to be able to glance over, understand the situation, and get back to what I was doing.

Checking what "done" means

The other part of AgentMon I care about is the completion check.

Consider a session where Claude runs the tests successfully, makes another code change, and then reports that everything passes. The earlier test result doesn't verify the latest edit.

AgentMon's "done gate" checks the recorded work before Claude finishes. It can catch things such as failed checks, tests that became stale after an edit, and unfinished todos. When it finds unfinished work, it sends that back to Claude once.

I still review the result myself. This helps catch some of the things I'd otherwise have to find by reading back through the session.

The README explains the checks in more detail.

Trying it

In a Claude Code session, install it with:

/plugin install agentmon-live --marketplace codenotary/agentmon-live

Follow the marketplace and scope prompts. You can open the pane with:

/agentmon

It also works with Code inside Claude Desktop. For that setup, install AgentMon as a mod in Claude Desktop itself rather than through Claude Code in your terminal.

The project is open source, with installation instructions on GitHub.

If you tried an earlier release, I'd love to hear how the browser view fits into your workflow. I'm especially interested in hearing from people juggling several sessions.

What do you find yourself checking most often while your agents are working?
