I just saw that LangChain now has cards for agents basically a way to standardize how agents display and organize outputs.
From what I understand, these aren’t just UI widgets, they’re structured result formats that agents can use to return richer, consistent info instead of plain text.
Feels like a small thing on the surface, but I think it’s actually about making agent output more predictable and reusable you can show data, suggestions, steps, or actions in a format that systems and humans can both read easily.
Curious what others think does this actually help make agent responses more reliable, or is it just a UI convenience for now?
