Cancellation Waitlist
Offer a freed-up slot to the people waiting for it, in order.
What it adds
A per-slot queue that automatically offers a released booking to waiting people one at a time.
What your agent is told to do
5
What your agent is told to do
5-
1
Let someone join the queue from the same screen where they found the slot full, capturing only what a booking needs, and confirm their position back to them.
-
2
When a booking is cancelled or released, offer the slot to the first person in the queue with a stated claim deadline, and move to the next person only when that deadline passes or the offer is declined.
-
3
Hold the slot for the person holding the live offer. If the slot stays openly bookable during the offer window, the queue means nothing and whoever refreshes fastest wins.
-
4
If the app already has a Waitlist feature for signup or capacity, extend it with slot-level queues and offer expiry rather than building a second waiting-list concept with its own table and its own notification path.
-
5
Do not notify everyone in the queue at once and let them race. It generates a burst of disappointment for everyone but one person and trains people to ignore the notification.
Edge cases it handles

Edge cases it handles
8- Every offer carries a claim deadline, and the slot moves to the next person automatically when it lapses. Without a deadline one unresponsive person blocks the queue until the appointment has passed.
- Two people must never claim the same released slot. Claim under a lock or a conditional update so the second claim loses cleanly and returns the person to their place in the queue.
- Entries whose slot has already started must be dropped rather than offered, and the person told the queue has closed for that time.
- Cap how many offers one person receives in a period. Someone waiting on a busy calendar can otherwise be notified repeatedly through the night.
- Every notification must carry a one-tap way to leave the queue that works without signing in, and leaving must take effect before the next offer is generated.
- A person holding a live offer who cancels their own place must release the slot immediately rather than letting the deadline run down.
- Respect the app's Quiet Hours if it has them, and decide explicitly whether a short claim deadline overrides them or the offer skips to the next person.
- Someone who books the slot through the normal flow while an offer is outstanding must be blocked, not silently allowed to jump the queue.
Definition of done

Definition of done
9- People can join a waitlist for a full slot and see their position.
- A cancellation offers the slot to the first waiting person with a visible claim deadline.
- The slot is held for the duration of an offer and cannot be booked around it.
- Concurrent claims on one released slot resolve to a single booking.
- Entries for slots that have started are dropped rather than offered.
- Offer notifications are rate limited per person and each carries a working leave-the-queue action.
- The feature extends the app's existing waitlist rather than duplicating it.
- The feature matches the existing design system.
- No existing functionality is broken.

Prize Wheel Giveaway
Prize Wheel Giveaway
Run a spin-the-wheel giveaway where each entrant gets one spin and a recorded prize.
What it does
A giveaway with a wheel interface, one server-decided spin per entrant, and a durable record of every result.
How it works
- 1 Decide the outcome on the server before the wheel starts turning. The request returns a prize, the animation lands on it, and the client is only ever playing back a result it was given.
- 2 Model prizes with explicit weights and optional stock counts, and let an operator edit them without a deploy. A giveaway whose odds live in code cannot be corrected once it is live.
- 3 Tie an entry to an account where the app has one, and where it does not, combine the strongest identifiers available and treat a single spin as the hard limit across all of them.

Live Chat Widget
Live Chat Widget
Let visitors ask a question from any page and get a real answer from your team.
What it does
A corner chat bubble that opens a persistent conversation between a visitor and staffed agents, with an agent-side inbox.
How it works
- 1 Build the visitor side first: a bubble, a transcript, a composer, and a clear statement of whether anyone is currently available. An agent inbox that reuses the app's existing list and detail patterns is enough for version one; do not build a full helpdesk with routing rules, tags, and SLAs before a single conversation has happened.
- 2 Keep the conversation attached to the visitor, not the page. Store a conversation identifier that survives navigation, reload, and moving between pages, and reattach the transcript when the widget reopens.
- 3 If the app already has Knowledge Base Chat or an AI Chat Assistant, put them in the same widget rather than adding a second bubble. Answer from the knowledge base first and hand off to a human when the visitor asks or the answer is not found.

Quiet Hours
Quiet Hours
Hold non-urgent notifications until the user actually wants to hear from you.
What it does
A per-user window during which outbound notifications are suppressed, with an explicit rule for what happens to anything that arrives inside it.
How it works
- 1 Extend the existing notification pipeline with a suppression check at send time. Do not build a second notification system.
- 2 Let the user set a start and end time and store the time zone the window was defined in.
- 3 Decide per notification type whether it is deferred to the end of the window, dropped entirely, or allowed through as urgent — and record that decision in the notification's definition, not in scattered call sites.

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.
