Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Sanctum is your digital cathedral — a gothic spiritual space for prayer, reflection, and ritual in the quiet glow of candlelight. Step beyond the noise of the modern world and enter a world of sacred stillness. Sanctum invites you to experience prayer, meditation, and mystic journaling through haunting soundscapes, sacred art, and AI-guided devotion. Whether you’re drawn to Christian mysticism, gothic aesthetics, or simply crave peace in darkness, Sanctum is an inclusive, meditative refuge designed for the soul. Key Experiences: • Light the Altar: Create your personal digital altar with candles, relics, and reflections. • Daily Liturgy: Receive a new gothic verse, prayer, or reflection inspired by sacred scripture and mystic writers. • Shadow Meditation: Explore your inner world through guided reflections that embrace both darkness and light. • Confession Booth: Release your thoughts in private text or voice form — they dissolve into smoke as you let go. • The Oracle (AI): Engage with an AI guide who offers scripture, poetry, or spiritual counsel in a gentle, contemplative tone. • Journal of Light: Keep a private candlelit journal for prayers, gratitude, and dreams — protected by password lock. • Gothic Ambience: Experience immersive sound environments — cathedral rain, Gregorian chant, organ echoes, and storm-lit stained glass. Customize Your Sacred Space: • Themes: Crimson Cathedral, Ash & Gold, Cemetery Fog, Midnight Marble. • Ambient Layers: adjust candlelight, rain, or choir sound intensity. • Altar Relics: unlock ancient symbols, charms, and stained-glass art. A Space for All Souls: Sanctum welcomes believers, seekers, and skeptics alike. It is not a church replacement — it’s a quiet place for anyone to meditate, pray, reflect, or simply feel.

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.

Intermediate
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.
