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
JapaCounter helps you track mantra repetitions with ease. Count manually or use auto mode with sound cues—even when your phone is locked. • Multiple mantras — Create and manage as many mantras as you need, with custom names and targets. • Manual & auto modes — Tap to count or let the app chant at your chosen interval. • Background chanting — Keep counting with the screen off; use lock screen controls to play, pause, or stop. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Users can tap/click that link on the App Store page; Apple treats it as the required “functional link” in metadata • Beep, bell, click, or TTS — Choose the sound that fits your practice. • Session history — See past sessions and track your progress over time. • Sync across devices — Sign in to back up your mantras and sessions and use them on all your devices. Whether you practice with a mala or prefer counting on your phone, JapaCounter is designed to stay out of your way so you can focus on your practice.

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.

BUILD KIT DIFFICULTY
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.
