What your agent is told to do
4-
1
Add a favorite toggle to the app's primary record type(s), on both the list and detail views.
-
2
Store favorites as a join between user and record with a uniqueness constraint — favoriting twice must not create two rows.
-
3
Give favorites a home: a filter on the list, and a section on the dashboard.
-
4
Update the toggle optimistically so it feels instant, but reconcile with the server response.

4- Double-clicking the star must not create a duplicate or leave the UI out of sync.
- Favoriting requires sign-in — prompt rather than silently doing nothing.
- A favorited record that gets deleted must be removed from favorites.
- A favorited record the user loses access to must not appear in their list.

Feedback Widget
Feedback Widget
Let anyone report a bug or send a comment from the page they are looking at.
What it does
An always-available launcher that opens a short feedback form and submits it with page context attached.
How it works
- 1 Put a single persistent launcher in one corner of the app and open a compact form in place. Do not route the user to a separate feedback page and lose the context they were about to describe.
- 2 Attach the current URL, the app version, the viewport size, the signed-in account, and a short trail of recent client errors automatically, so the reporter does not have to describe where they were.
- 3 Show the captured context to the user before they send it, in a collapsible section, and let them remove it. Silent collection of screen state is a trust problem.

Booking Page
Booking Page
A shareable page where someone picks an open time and confirms it in a few clicks.
What it does
A public scheduling page listing open slots, taking a booking, and confirming it to both sides.
How it works
- 1 Build the visitor path first: pick a date, see open times in their own zone, fill a short form, confirm, and receive an email with the details and a cancellation link. That is the minimum coherent version.
- 2 Derive open slots from the owner's availability rules and existing bookings on the server at request time. Do not trust a slot list the browser has been holding since page load.
- 3 Reuse the app's existing Time Zone-Aware Scheduling for conversion and storage, store every time as an absolute instant, and display it converted to the visitor's detected zone with the zone named on screen.

Audio Chapter Markers
Audio Chapter Markers
Break a long recording into named chapters listeners can see and jump between.
What it does
Named, timestamped chapters on long audio or video, shown in a list and on the scrubber, each addressable by its own link.
How it works
- 1 Store chapters as an ordered list of start times and titles attached to the existing media record, and render them both as a list beside the player and as markers on the scrubber.
- 2 Let an author add, rename, reorder by moving start times, and delete chapters in the player itself, with the current playback position offered as the default start time for a new chapter.
- 3 If chapters are generated automatically, treat the generated set as a first draft. The author's edits must win and must survive the next generation run.

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.
