Advanced Filters
Let people narrow a big list down to the rows they want.
What it adds
Composable filters on your main list views, reflected in the URL.
What your agent is told to do

What your agent is told to do
4-
1
Filter on the fields people actually care about. Ask what questions users are trying to answer.
-
2
Put the active filters in the URL so a filtered view can be bookmarked and shared.
-
3
Show which filters are active, and make them removable individually and all at once.
-
4
Filter server-side. Fetching everything and filtering in the browser breaks the moment the data grows.

4- A filter combination that matches nothing must show a filtered-empty state with a way to clear it — not a first-run empty state.
- Filters must combine correctly (AND vs OR must be explicit and predictable).
- A shared filter URL must not expose records the recipient can't see.
- Pagination must reset to page 1 when filters change.

Global Search
Global Search
One search box that finds anything in your app.
What it does
Search across every meaningful entity in the application from a single input.
How it works
- 1 Identify every entity worth searching, and report them before building.
- 2 Use the database's own search capability first (for example Postgres full-text search). Do not add Elasticsearch or a search SaaS unless the project already has one.
- 3 Return results grouped by entity type, strongest match first.

Voice Search
Voice Search
Let people speak a search query instead of typing it, and still edit what was heard.
What it does
A microphone control on the app's existing search field that turns speech into a query the user can correct before it runs.
How it works
- 1 Add the microphone to the search input the app already has. Do not build a separate voice search screen or a second results page; the spoken query must go through the same search, the same filters, and the same ranking as a typed one.
- 2 Show words as they are recognised, in the search field itself, so the user can see the microphone is working before the final result arrives.
- 3 Leave the recognised text in the field as ordinary editable text once recognition finishes. The single most common repair is the user fixing one wrong word and pressing enter.

Saved Filters
Saved Filters
Let people keep the views they build.
What it does
Save a filter combination as a named view the user can return to.
How it works
- 1 Let a user name and save the current filter state, and list their saved views.
- 2 Store the filter definition, not the matching row IDs — a saved view must stay live as data changes.
- 3 Allow editing, renaming, and deleting saved views.

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.
