Record Merge
Combine two duplicate records into one without losing anything attached.
What it adds
A merge flow that picks a surviving value per field, reparents all related data, redirects old references, and can be audited afterwards.
What your agent is told to do

What your agent is told to do
5-
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.
-
4
Redirect old references: keep the losing record's ID resolvable and point it at the survivor, so bookmarks, external links, and API consumers do not break.
-
5
Lock both records for the duration of the merge and write an audit entry recording who merged what, which values survived, and when. Do not build identity or account merging here — that is owned by Account Merge — and do not add pre-create duplicate warnings, which are owned by Duplicate Detection on Create.
Edge cases it handles

Edge cases it handles
6- Concurrent edits to either record during the merge must be rejected or forced to re-read, not silently discarded.
- Merging a record into itself, or merging records the actor can only partially see, must be refused up front.
- Records in different workspaces, tenants, or permission scopes must not be mergeable without an explicit rule for which scope survives.
- Timestamps need a decision: created_at should usually take the earlier of the two, not the survivor's.
- Merges are effectively irreversible once children move. Either implement an undo window or say plainly in the confirmation that it cannot be undone.
- Very large merges — thousands of children — must run in the background with progress, not block a request until it times out.

Definition of done
8- Every conflicting field requires an explicit survivor choice before the merge can run.
- All related records move to the survivor within one transaction, with no orphans left behind.
- Relationships that would duplicate after reparenting are collapsed instead of erroring.
- The losing record's ID still resolves and redirects to the survivor.
- Both records are locked during the merge and concurrent edits are rejected.
- An audit entry records the actor, both records, and the surviving values.
- The feature matches the existing design system.
- No existing functionality is broken.

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.

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.

QR Code Generator
QR Code Generator
Turn a link, some text, or a contact detail into a QR code people can print or download.
What it does
A QR code generator with live preview, optional branding, and downloads suitable for both screen and print.
How it works
- 1 Generate the code in the browser and update the preview as the user types, so they can see immediately when the content gets long enough to make the code too dense to be practical.
- 2 Support the kinds of content the app actually needs to encode: a link, plain text, and contact details. Do not ship a menu of a dozen formats where most produce codes nobody in this app will scan.
- 3 Offer both a raster download for screens and a vector download for print, and make the vector the default when the user's stated use is printing.

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.
