Responsive Data Tables
Make your tables usable on a phone instead of a horizontal scrollbar.
What it adds
Tables that stay readable on small screens without turning into a sideways-scrolling mess.

What your agent is told to do
4-
1
Find the app's data tables and identify, for each, the one or two columns that actually matter. That is what survives on mobile.
-
2
On small screens, collapse each row into a stacked card showing the primary columns, with the rest available on tap.
-
3
Keep sorting and filtering available on mobile — do not quietly drop them.
-
4
Preserve the semantic table on desktop. Do not replace it with divs; screen readers rely on the table structure.

4- Very long cell values must truncate with a way to see the full value.
- Row actions must remain reachable on mobile, not hidden behind hover.
- A table with hundreds of rows needs pagination or virtualization, not a longer page.
- Sticky headers must not cover the first row on short viewports.

- The most important columns are the ones visible on mobile.
- Sorting, filtering, and row actions still work on a phone.
- Desktop keeps a real, semantic .
- Hover-only actions have a touch equivalent.
- The feature matches the existing design system.
- No existing functionality is broken.

Beautiful Empty States
Beautiful Empty States
Replace blank screens with useful, contextual empty states.
What it does
Every list, table, and dashboard in your app has a "nothing here yet" state. Most
apps ship a blank rectangle — and it is often the very first thing a new user sees.
An empty state should say what belongs here, why it is empty, and what to do next.
How it works
- 1 Inventory the empty cases first. List every collection view in the app and

Media Aspect Ratio System
Media Aspect Ratio System
Give every thumbnail, avatar, and hero a shared, reserved shape so nothing jumps.
What it does
A small set of named aspect ratios applied to every image and video surface, with reserved space, a defined fit, and a defined fallback.
How it works
- 1 Catalogue the media surfaces already in the app — list thumbnails, card covers, avatars, hero banners, video embeds, attachment previews — and reduce them to a handful of named ratios rather than a per-component value.
- 2 Reserve the box before the media loads so the ratio holds space from first paint. Layout that settles after an image arrives moves whatever the user was about to click.
- 3 Set the fit per content type, not per component: faces and product shots crop to fill from a sensible focal point, diagrams and screenshots fit whole with padding, because cropping a diagram loses the content it exists to show.

Opening Hours Display
Opening Hours Display
Say whether you are open right now and when you next open.
What it does
A live open or closed state alongside the weekly hours, with holiday closures folded in.
How it works
- 1 Lead with the current state in plain words and follow it with the next transition: open until a time, or closed until a day and time. The weekly table is supporting detail, not the headline.
- 2 Store hours as intervals against the business's own zone, and keep holiday and one-off closures as overrides that win over the regular week rather than as edits to it.
- 3 Compute the state on the server for the first render so the page does not briefly claim the wrong thing, then let the page update itself as the clock crosses a boundary without a reload.

It inspects, then implements
Your agent reads your existing app first, then adds the feature to fit it.
Works with your stack
These instructions are written to adapt. They tell the agent to detect your framework, match your existing design system, and reuse what you already have — rather than assuming a particular stack.
Need it tighter than that? Customize the feature and tell it exactly what you're running.
