open source ui components where every hover, transition, and animation serves a purpose.

Built on top of shadcn/ui and radix.
One CLI command to install.

@guerriero_se Looking forward to this!

@qhoang09 Let's go! But also, can I know who said this? "This is the most beautiful UI I've seen in any agent builder" YC Founder

@lochieaxon Makes a lot of sense for Inter 4.0. Need to implement that for https://t.co/qTxRMn2aaB
I was calculating the hovered text width to avoid any shifts but this is visually cleaner.

[Micka @micka_design]

@antonleogky Ouuu I love this trick. Makes so much sense. Thanks man!

Passed a few quality of life improvements on two most-requested tweaks for the AskUserQuestions component:

- Freeform “other” option is now a real textarea
- New chip layout variant (left-aligned)

The reception on this component has been unreal with teams are already implementing it in production and triggering great discussions.

Community-driven open source at its best.

Keep the feedback coming, it’s shaping everything.

@benjitaylor @xai These negative dot mixing with the BG are 👌🏻

[Micka @micka_design]

@sashimikun_void Definitely can, and probably should. Was consistent with the textfield but I agree it feels too much. Will be cleaner without. Thanks for the nitpick!

[Micka @micka_design]

@zach3george Thanks, will check this our later this week and let you know.

[Micka @micka_design]

@roguesherlock Thanks man. I'm curious, any component in particular you instantly vibed with?

When everyone on your team can build anything, shipping velocity becomes the easiest thing to celebrate.

But here’s the trap: asking an agent costs seconds. Asking a colleague costs minutes. Do that a few times a day and you start using your AI as head of product.

Over a quarter, you end up with a pile of decisions no one made together. Every PR is defensible. Every change makes sense in isolation. And yet the product drifts.

I caught myself doing exactly this: aligning at the PR level instead of earlier. The problem is not when we review. It’s what we review.

PRs show code. PRDs show intent. Neither shows behavior.

I wrote about what I think the fix is: prototype the actual behavior, review it together, throw it away, and rebuild it right.

@DamianSkotzke Probably the most enjoyable part when interacting with an agent in 2026. Still many things to do left. So many things to create still around these:
Was mind blown today with the queue messages and give permissions UIUX from Codex.

[Micka @micka_design]

New component: AskUserQuestions
- Clear affordance between single select and multi select
- Keyboard powered
- Seamless "other" option
- Fluid Functionalism's proximity hover
- Inline or stacked descriptions
- Motion and subtle animation just on what matters

@tkwoncpa Indeed, thanks for sharing!

[Micka @micka_design]

@mcign69 @base_ui @colmtuite Glad to hear. My DMs are open (to start with)!

[Micka @micka_design]

https://t.co/yzbtQ6V9zj now runs on Radix or
@base_ui. your call.

I build a page to show you what changes: nothing. And that's beautiful.

@abhagsain Adding it on the next version! Thanks for the tip (Codex screenshot)

[Micka @micka_design]

@DmitrijVin70043 Hahaha! I’m sure for answers. For the question and description it will depend on the max height you’ll want to setup at the container level. Should be robust right now but depends on the implementation.

[Micka @micka_design]

@cristicrtu Thanks man! Anything you would adjust?
