Because I find it difficult to read the textual output of agents after each modification or planning, and relate everything to the big picture, I built this simple application (with the help of Claude Code).
It is an Electron application that has an integrated terminal linked to the Chalkboard. Any agent you run in this terminal can use it and express its textual outputs in graphics that are easier to review.
Some may find the sounds a little annoying, but it's just an adjustable option, which I prefer.
Using it may cause a bit more token consumption or subscription quota, but in my experience with Claude Code I haven't seen a noticeable difference. In general, the project is open source for anyone who wants to try it or modify it.
