Quiet Hours
Hold non-urgent notifications until the user actually wants to hear from you.
What it adds
A per-user window during which outbound notifications are suppressed, with an explicit rule for what happens to anything that arrives inside it.
What your agent is told to do
5
What your agent is told to do
5-
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.
-
4
Deliver deferred messages as a single digest when the window ends, not as a burst of twenty separate pushes.
-
5
Do NOT let quiet hours suppress security messages — password changes, new sign-ins, billing failures. A user who cannot be reached about account compromise is worse off than one who was woken up.
Edge cases it handles

Edge cases it handles
6- Evaluate the window against the user's current time zone, not the server's and not the one they signed up in.
- A window that crosses midnight (22:00 to 07:00) is the common case, not the exception. Handle it first.
- Daylight-saving shifts can make a window an hour shorter or longer, and can make a deferred send time occur twice or not at all.
- A deferred notification about a record that was since deleted or resolved must be dropped, not delivered stale.
- Ten deferred notifications about the same record must collapse into one on release.
- Turning quiet hours off mid-window should release the queue immediately, not wait for the original end time.

Definition of done
8- Non-urgent notifications sent inside the window are not delivered during it.
- Windows crossing midnight behave correctly.
- The window is evaluated in the user's current time zone and survives daylight-saving changes.
- Each notification type has a declared behaviour: defer, drop, or bypass.
- Deferred messages arrive as one digest, with stale entries removed.
- Security and billing notifications always bypass the window.
- 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.

Poll Widget
Poll Widget
Ask a one-question poll anywhere in the app and show the results as soon as someone votes.
What it does
An embeddable single-question poll with a vote control and a results view revealed after voting.
How it works
- 1 Keep it to one question with a small set of options. The moment it grows a second question it is a survey and belongs in the survey feature instead.
- 2 Record the vote on the server and return the updated tallies in the same response, so the results the voter sees are the real counts rather than an optimistic local guess that may disagree after a refresh.
- 3 Hold voting open to signed-out visitors if the poll is public, and identify them well enough to prevent casual repeat voting without demanding an account for a single click.

Announcement Bar
Announcement Bar
Put a timed message across the top of the site without shipping a deploy.
What it does
An operator-configured, dismissible strip at the top of public pages, with scheduling and a link.
How it works
- 1 Extend the existing Service Incident Banner rather than adding a second bar. It already handles scheduling, targeting, dismissal, and severity; this is a marketing-styled variant of the same component, and two independent bars will eventually stack on top of each other.
- 2 Let an operator set the message, an optional link, background and text colours, and a start and end time from an admin screen. Requiring a deploy to run a weekend promotion means it goes live late.
- 3 Insert the bar into the document flow so it pushes fixed headers and sticky navigation down. Overlaying it on top of the header hides navigation on exactly the pages people arrived on.

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.
