User Identity Display
Show who someone is the same way on every screen, including when the record is gone.
What it adds
A single component that renders a person's avatar, name, secondary label, and role wherever a human is referenced.
What your agent is told to do
5
What your agent is told to do
5-
1
Identify every surface that names a person — assignees, comment authors, audit entries, member lists, mentions, hover cards, activity feeds — and replace each bespoke rendering with the shared component.
-
2
Define the fallback chain once and apply it everywhere: display name, then full name, then the email local part, then a neutral placeholder. Never fall through to a raw identifier.
-
3
Generate initials and a placeholder avatar deterministically from the stable account identifier, so the same person keeps the same colour and shape across sessions and screens.
-
4
Give the component explicit variants for account states — active, invited, deactivated, deleted — so callers pick a variant rather than each screen inventing its own way to grey someone out.
-
5
Do not have every instance fetch its own profile. A table of two hundred rows must resolve the people it references in one request and hand the resolved records to the component.
Edge cases it handles
7
Edge cases it handles
7- Users who are deleted, still pending an invitation, or suspended must still render as something recognisable. A comment written by someone who has since left should say so plainly rather than showing a blank space or the word 'null'.
- Privacy rules decide what a given viewer may see. Someone outside a workspace may be entitled to a display name and nothing else — never let an email address reach a viewer who has no right to it just because the component happened to receive one.
- Long names, names that are a single very long token, and names in scripts with no spaces will all overflow. Truncate visually with the full value available on hover and in the accessible name, and never truncate mid-grapheme.
- Identity must be keyed on the immutable account identifier, not the display name, so a person who renames themselves does not appear as two different people in the same thread.
- Names carry scripts, diacritics, right-to-left text, and emoji. Initials derived by taking the first letter of each word will produce nonsense for some of them, so degrade to a neutral placeholder rather than a wrong initial.
- System and automation actors — the scheduler, an integration, an API key — appear in the same lists as people and need their own variant instead of being dressed as a user.
- Avatar images fail to load, and the fallback must occupy exactly the same box so nothing reflows when it does.
Definition of done

Definition of done
9- Every reference to a person in the app renders through the shared component.
- Deleted, invited, and suspended accounts each render in a distinct, legible state rather than blank.
- No field is displayed that the current viewer is not permitted to see.
- The same person shows the same placeholder colour and initials on every screen and after a rename.
- Long and non-Latin names truncate without breaking layout, with the full value accessible.
- A list of many people resolves their profiles in bulk rather than one request per row.
- A failed avatar image leaves the layout unchanged.
- The feature matches the existing design system.
- No existing functionality is broken.

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.
