Undo Actions
Let people take it back, instead of asking them if they're sure.
What it adds
An undo affordance for destructive actions — usually a better answer than a confirmation dialog.
What your agent is told to do
4
What your agent is told to do
4-
1
Find destructive actions currently gated behind a confirmation dialog. Where the action can be made reversible, replace the dialog with undo.
-
2
Implement undo as a REAL reversal: soft-delete with a restore path, or a deferred commit. Do not fake it by hiding the row while the delete has already committed server-side.
-
3
Surface undo in a toast that lasts long enough to use — roughly 8–10 seconds, longer for bulk actions.
-
4
Support Cmd/Ctrl+Z for the most recent undoable action.
Edge cases it handles
5
Edge cases it handles
5- The user navigates away before undoing — the action must still commit correctly.
- Several undoable actions in quick succession — each needs its own undo, or a stack.
- The undo window expires while the toast is still visible — disable the button rather than failing silently.
- Undo fails server-side — say so; never pretend it worked.
- Cascading deletes are often irreversible. Do not offer undo where you cannot deliver it.
Definition of done

Definition of done
7- Undo genuinely restores state — verified server-side and after a refresh.
- The undo window is long enough to actually use.
- Cmd/Ctrl+Z triggers the last undo.
- Actions that cannot be reversed still use a confirmation dialog.
- A failed undo is reported, not swallowed.
- 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.

Interactive Transcript
Interactive Transcript
Put the transcript next to the player so clicking any line jumps playback to that moment.
What it does
A time-aligned transcript panel beside the audio or video player, with click-to-seek, a moving highlight, and in-transcript search.
How it works
- 1 Render the transcript from the timestamps the app already stores. If Voice Transcription exists, extend its output and its data model rather than producing a second transcript with its own timings.
- 2 Make every line a real seek target: clicking or pressing enter on a line moves playback to that time and keeps focus where the user left it.
- 3 Highlight the line currently being spoken and keep it in view as playback advances, using the player's own time updates rather than a separate timer.

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.

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.
