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

Welcome to Cosmic Deepsky, where the marvels of the universe come alive through the lens of your device – your very own magic telescope. We live on a planet cruising through space, surrounded by the vast expanse of the cosmos. The canvas of our existence extends far beyond the confines of our planet, stretching into the depths of the celestial sphere above and below. By day, our atmosphere dances with the brilliance of sunlight, casting a cerulean glow upon the world. Yet, as night descends, a grand spectacle unfolds. Against the backdrop of darkness, myriad suns dot the heavens, weaving intricate constellations that have captivated humanity for millennia. Here, amidst the twinkling stars, lies the gateway to the deep sky – a realm where gas clouds and cosmic debris coalesce, painting celestial masterpieces with the strokes of light and gravity. Among these wonders, stars congregate in clusters, while others journey across the galactic plane in majestic arcs. Supernovae remnants and planetary systems adorn the spiral arms of our Milky Way galaxy, a cosmic tapestry of stellar life. Yet, the deep sky knows no bounds, extending far beyond our galactic borders to distant neighbors like the Magellanic Clouds and the majestic Andromeda galaxy. With Cosmic Deepsky, we invite you to peer into the depths of the universe like never before. Featuring the positions of the 4000 brightest and closest galaxies, alongside stunning real images of hundreds of them meticulously measured and oriented by hand, our app offers a unique window into the cosmic expanse. Delve into the depths of intergalactic space, where millions of galaxies beckon with their luminous allure, their distant light captured in mesmerizing astro-photographs. Embark on a journey of discovery and wonder as we unveil the mysteries of the cosmos. Through Cosmic Deepsky, may you find inspiration and awe in the boundless beauty that surrounds us, igniting a newfound appreciation for the magical universe we call home.

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.
