Autosave
Stop people losing work in your forms and editors.
What it adds
Save the user's work automatically, and tell them honestly when it is and is not saved.
What your agent is told to do

What your agent is told to do
4-
1
Find the long-form inputs and editors — anywhere a user can lose more than a few seconds of work.
-
2
Debounce saves (roughly 1–2s after typing stops) and also save on blur.
-
3
Show save status honestly: unsaved, saving, saved, or failed. Never show 'Saved' while a request is in flight or has failed.
-
4
Keep a local draft so a crash or a closed tab does not lose content.
Edge cases it handles

Edge cases it handles
5- The network drops mid-save — retry with backoff and keep showing 'unsaved'.
- The user closes the tab with unsaved changes — warn via beforeunload.
- Two tabs edit the same record — detect the conflict instead of silently overwriting.
- The record is deleted by someone else mid-edit — surface that.
- A very large document — do not send the entire payload on every keystroke.

7- Work is saved without the user pressing anything.
- Save status is always accurate, including during failures.
- A dropped connection does not lose work; the save retries.
- Closing the tab with unsaved changes warns the user.
- A local draft survives a refresh or crash.
- 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.

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.

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.

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.
