Interactive Transcript
Put the transcript next to the player so clicking any line jumps playback to that moment.
What it adds
A time-aligned transcript panel beside the audio or video player, with click-to-seek, a moving highlight, and in-transcript search.
What your agent is told to do

What your agent is told to do
5-
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.
-
4
Add a search box over the transcript that lists matches and jumps playback to any of them. Reuse the app's existing search match highlighting so results look the same as everywhere else.
-
5
Do not render thousands of lines into the page at once. Virtualise the list, and make sure seeking to a far-off match still works when the target line has not been rendered yet.
Edge cases it handles

Edge cases it handles
8- Auto-scrolling the active line into view fights a user who is scrolling by hand. Suspend follow mode as soon as they scroll away, and offer a visible control to jump back to the current position.
- A transcript of several thousand lines will stall the page if every line is mounted and every line re-renders on each time update. Virtualise, and update only the lines whose highlight state actually changed.
- In-transcript search must show how many matches there are and let the user step between them, jumping playback to each. A search that only dims non-matching text is not enough on a long recording.
- Changing playback speed must not drift the highlight. Derive the active line from the player's reported current time, never from an interval that assumes real-time playback.
- On a narrow screen the side-by-side layout has to stack, with the player pinned so it stays visible while the user scrolls the transcript. A transcript that scrolls the player off the top is unusable.
- Lines with missing or overlapping timestamps must still render as text and simply not be clickable, rather than seeking to zero.
- Seeking must survive the media not being loaded yet: queue the seek and apply it once the player is ready.
- The transcript must remain selectable and copyable as plain continuous text, including across the boundaries of virtualised lines.

9- Clicking or keyboard-activating any line seeks playback to that moment.
- The active line is highlighted and follows playback, and manual scrolling suspends follow until the user returns.
- A transcript of several thousand lines scrolls and highlights without visible lag.
- In-transcript search reports match counts and jumps playback to each match.
- The highlight stays correct at every supported playback rate.
- The layout stacks on narrow screens with the player still visible.
- Transcript text can be selected and copied as continuous prose.
- 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.

Reschedule and Cancel Links
Reschedule and Cancel Links
Give every booking confirmation a link the person can use to move or cancel it.
What it does
Tokenised self-service links in booking confirmations and reminders that let the attendee change or cancel without signing in.
How it works
- 1 Put the two links in the booking confirmation, in every reminder, and on the confirmation screen itself. A person looking for the link is usually looking in the last message they received.
- 2 Land the link on a page that restates the booking in plain terms before offering any action, so someone who opened it by accident can see what they are about to change and back out.
- 3 Reuse the app's existing Signed Share Links mechanism for token generation, expiry, and revocation rather than inventing a second token scheme. If the app has Magic Link Sign-In, note that this link grants access to one booking only and must never establish a full session.

Permission-Aware Action
Permission-Aware Action
Decide once how a control behaves when the user is not allowed to use it.
What it does
A shared wrapper for buttons, menu items, and links that resolves visibility, disabled state, and the reason a user cannot proceed.
How it works
- 1 Inventory every action in the app that any role can be denied, and give each one a named capability rather than scattering role comparisons through the components that render it.
- 2 Pick one of three treatments per action and record the choice: hide it, show it disabled with a reason, or show it enabled and let the attempt fail into an upgrade or request-access path. Defaulting everything to hidden makes the product look smaller than it is.
- 3 Whenever an action is disabled, say why in words the user can act on — the role that is required, the prerequisite that is missing, the plan limit that has been reached — and where possible offer the next step.

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.
