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

You just booked a cruise. A week later, the same cabin is $400 cheaper, and the cruise line never tells you. Cruise lines use aggressive dynamic pricing. Fares change daily based on demand, inventory, and proximity to sail date. Most major lines — Royal Caribbean, Carnival Cruise Line, Norwegian Cruise Line, MSC Cruises, and others — will honor a price drop if you catch it before final payment. But only if you ask. Almost no one does, because almost no one is checking every day. CruiseSignal does the checking for you. HOW IT WORKS 1. Add your booking in 30 seconds — cruise line, ship, sail date, cabin type 2. We track your exact fare every day, automatically 3. The moment the price drops, you get notified with the new price, your savings, and what to do next 4. Contact your cruise line or travel agent, reference the lower fare, and claim the difference as a refund or onboard credit WHY IT WORKS Cruise pricing is one of the most volatile in travel. A balcony cabin can swing hundreds of dollars in a single week. Because the system favors the cruise line — they keep the higher fare unless you flag the drop — most passengers leave money on the table without realizing it. We built CruiseSignal so you never have to manually check fares again. Set it once, and we monitor your price all the way to your sail date. FEATURES • Daily automated price tracking • Instant alerts when prices drop • Clear before/after pricing comparisons • Step-by-step guidance to claim refunds or credits • Track multiple bookings (yourself, family, groups) • Works with major cruise lines including Royal Caribbean, Princess Cruises, Holland America Line, Celebrity Cruises, and Disney Cruise Line WHO IT’S FOR • Anyone who’s already booked a cruise and doesn’t want to overpay • Travel agents managing client bookings • Frequent cruisers who know how much fares move Stop refreshing cruise sites. Add your booking, move on with your life, and let us track the price. CruiseSignal is free to download. A subscription is required to unlock various features.

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.

A reliable timeline needs an agreed scope and a technical check. Ask your agent to estimate the phases in BUILD_PLAN.md after that review.
