Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

Screen plan

Invoice editor: Client at the top, editable line items in the middle, total and preview action at the bottom.

States: Empty draft, validation errors beside each field, exporting, and a retry action that preserves the draft.

Differentiate and validate

Hypothesis: Contractors need faster repeat invoices more than more templates.

First experiment: Test duplicating a previous job with five contractors. Watch where they hesitate before expanding the feature set.

The full kit adds a phased build plan, evidence notes, tool prompts, and implementation guidance. It is a plan for your coding agent, not a finished app.

Usage: Mechanics are fair game; never reuse the original name, branding, assets, or verbatim copy.

App Store description

Claude Duet is available through a waitlist. Before you download, check that you've received our email saying your account has access. If you haven't, join the waitlist at claude.com/product/claude-duet. WAKE UP KNOWING WHAT NEEDS YOUR ATTENTION Each morning, Claude Duet looks across your email and calendar and brings you the few things that need a decision or a reply. It provides context on each one, so you have what you need to decide right there. Where it can, it has a draft ready for you to review. Through the day, it checks your connected accounts every few hours and flags what's gone quiet, like a client email you haven't answered in a few days. HAND IT OFF Ask in a chat or add a task. Claude Duet gets going, sends you updates as it works, and tells you when it needs your review. GET THINGS MADE FROM A SINGLE MESSAGE Describe what you need in one message. It comes back as work you can check, like a brief, research, or a draft. YOU HAVE THE FINAL SAY Claude Duet waits for your okay before it sends, posts, pays, or deletes anything. It works with the apps you've connected to Claude, and you can disconnect any of them at any time. ORGANIZE BY CHANNEL Keep each part of your work in its own channel, like one for finance and one for hiring. Claude Duet can read across all of them, so it keeps the whole picture. THE CLAUDE YOU KNOW Claude Duet runs on your Claude account, with your memory, skills, and connected apps like Gmail and Google Calendar there from the first message. IT KEEPS WORKING Claude Duet works in the background even after you close the app. It will let you know when it's done or needs your approval. TALK IT THROUGH When you'd rather talk than type, hold to talk or have a spoken conversation. WHAT TO EXPECT We built Claude Duet for work, so it's weaker at personal errands. It can make mistakes, including about what's urgent. Emails and web pages written by other people can contain hidden instructions meant to mislead it. Claude Duet is built to resist these, but review what it shows you before you approve. Because it checks every few hours, something urgent can arrive between checks. Learn more at support.claude.com/en/articles/17631495. HOW TO GET ACCESS Join the waitlist at claude.com/product/claude-duet. We'll be adding people gradually, and we'll email you when your account has access. Please note, signing into the app doesn't add you to the waitlist.

Opportunities

AI-GENERATED OPPORTUNITY HYPOTHESES

These are generated suggestions, not verified review quotations. Check current App Store reviews and speak with users before treating a possible gap as a requirement.

Hypothesis 1

Full offline with background sync

Assumption to check: No offline mode

Validate with people who use this workflow before building.

Hypothesis 2

Real-time sync with conflict resolution UI

Assumption to check: Sync issues

Validate with people who use this workflow before building.

Hypothesis 3

Minimal design, progressive feature disclosure

Assumption to check: Feature bloat

Build scope

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.

Define the first version

Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.

Set boundaries

Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.

Check the hard parts

Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
