What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Explore the Fortified Lifeline of Ancient Athens on your iPhone, iPad, or Mac. Follow the leadership of Themistocles and Pericles as you traverse the story of the Long Walls — massive fortifications that once connected Athens to her ports at ancient Piraeus and Phaleron, securing the city’s power during the Golden Age. The Athenian Long Walls app brings this ancient infrastructure to life through immersive, map-based storytelling. Spanning over 7 kilometers each, the Long Walls ensured Athens could withstand siege and maintain maritime dominance. Though little remains visible today, their imprint still shapes the modern landscape. Whether you're walking the streets of Athens and Piraeus or exploring from afar, the app offers a guided, interactive way to experience history. HOW IT WORKS The story unfolds through Journeys that combine narrative, imagery, and interactive maps: * Each Journey includes a Summary and a sequence of Passages, each tied to a specific location. * Some Passages unlock Supporting Passages offering deeper, site-specific insight. * Follow the curated progression — or roam freely across the map. WHAT YOU'LL EXPLORE * Journeys 1–4 trace the political and military decisions behind the walls' construction, from early motivations to their critical role in the Peloponnesian War. * Journeys 5–7 identify and describe the archaeological remains still visible in Athens, Piraeus, and Phaleron today. * Journey 8 presents a 26-step timeline of key events that shaped the rise and fall of the Athenian Empire in the 5th century BCE. POWERED BY JOURNEY MAPS Built on the Journey Maps platform — a patent-pending system for geographic storytelling — Athenian Long Walls seamlessly integrates history, narrative, and interactive maps, offering a fresh, engaging way to explore the past. The Long Walls is a one-time purchase — no subscriptions, no ads. Own the full historical experience forever — and uncover the hidden story that shaped an empire.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
From the Build Kit assessment.
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.
