Drag-and-Drop Reordering
Let people put things in the order they want.
What it adds
Reorderable lists that persist the new order.
What your agent is told to do

What your agent is told to do
4-
1
Persist order in a dedicated position column. Do not rely on created_at or id.
-
2
Update the UI optimistically, then persist — and roll back visibly if the save fails.
-
3
Provide a KEYBOARD alternative. Drag-and-drop alone is inaccessible and unusable on some devices.
-
4
Consider fractional or gap-based positions so reordering one item doesn't rewrite every row.
Edge cases it handles

Edge cases it handles
5- Two users reordering at once must not corrupt the order — decide on last-write-wins or a conflict strategy.
- A failed save must visibly revert, not leave a lie on screen.
- Reordering must work with pagination, or pagination must be disabled for orderable lists.
- New items must land in a predictable position.
- Respect prefers-reduced-motion in the drag animation.

Weather Widget
Weather Widget
Show current conditions and a short forecast for a place your users care about.
What it does
A compact widget showing current conditions and a few days of forecast for a chosen location.
How it works
- 1 Add this as a tile in the app's existing Customizable Dashboard Widgets rather than as a fixed element bolted into a layout, so users who do not want it can remove it.
- 2 Fetch the forecast on the server on a schedule and serve the widget from the app's own cache. Calling the weather source from every visitor's browser leaks the credential and multiplies the request count by your traffic.
- 3 Show the observation time alongside the reading, and reuse the app's Stale Data Indicator conventions so ageing weather looks the same as any other ageing data in the product.

Location Map Block
Location Map Block
Put an interactive map on a page showing one location or a whole list of them.
What it does
A reusable map block rendering one or many pinned locations, with a static fallback and a text address alternative.
How it works
- 1 The app already has Mapbox Geocoding and Google Places Address Lookup. Turn addresses into coordinates through the existing integration and store the result on the record; do not add a second geocoding path for this block.
- 2 Make the block take either a single location or a collection, and render the same component for both. A one-pin map is a collection of one, not a separate feature.
- 3 Reserve the block's height before the map initialises so the surrounding page does not jump when tiles arrive. The placeholder should occupy exactly the space the map will fill.

Record Merge
Record Merge
Combine two duplicate records into one without losing anything attached.
What it does
A merge flow that picks a surviving value per field, reparents all related data, redirects old references, and can be audited afterwards.
How it works
- 1 Show the two records side by side, field by field, and require an explicit survivor for every field where they differ. Do not default to 'newest wins' silently; the user is merging because they know which one is right.
- 2 Reparent every related object — children, comments, attachments, activity, links, memberships — onto the survivor in a single transaction. A half-finished merge is worse than two duplicates.
- 3 Detect relationships that would become duplicates after reparenting (the same person as a member of both records, the same tag applied twice) and collapse them rather than violating a uniqueness constraint mid-merge.

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.
