Over the past week or so I started building Handler, an A2A Protocol client TUI and CLI.

I use handler primarily for sending messages to A2A server agents at work. This was tedious to do with curl commands or running a local A2A inspector and port forwarding or hitting errors from protocol versions.

So I built this and thought I'd share it.

Let me know what you think! Or if there are any features you'd like to see implemented.

This is a very early version of the tool so expect bugs and missing features.
