@calm-artist-7206 @wooden-umbrella-84098 Following up on this discussion: https://openhands-ai.slack.com/archives/C06QT0AGY4W/p1780409636257709 The PR, feat(chat): per-tool visualizers for tool calls in the conversation UI, adds a registry to visualize tool calls (effectively a pretty printer for tool calls). Additionally, I have already added visualizers for the most frequently used tools (see images). @millions-afternoon-47582 I tried to follow the repo's conventions, but I might have missed a few things (as the PR is pretty big). Let me know if I should change something, or if you want something different. @breezy-kilobyte-39430 I didn't focused on the design (every tool call was a raw json, so everything was better 🙂 ). Feel free to change the UI/UX in a follow-up PR if needed.

Thank you! My follow up question is how easy is it for the user to define a visualizer for an event or more, and do they need to edit code? I feel like we could benefit from offering a plugin-like experience here. Not in scope for the PR, I just sent off my agent to look into it

ah ok... So the PR is good for you rigth?

Yes!

It looks good to me, there's a design pass we are going to make on the conversation in the future but this looks fine for now.
