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

Days Until: Countdown If you're anything like me, you may have tried to keep everything in your brain, at once. I created Days Until: Countdown because I wanted a tool where I can practice intentionality (e.g., pausing and inputting the dates that were important). View this app as a relationship with intentionality, to pause, breathe, and track the things important to you. It's helpful to see your countdowns in one clean vertical list. Built for everyday life and professional work: lawyers tracking filing dates, legal assistants watching response deadlines, office managers keeping team dates visible, students watching exams, and anyone who wants important dates out of their head and in one clear place. Use Days Until for: Legal and filing deadlines Bills, rent, and renewal dates School assignments and exams Office deadlines and follow-ups Trips and travel dates Birthdays and anniversaries Job applications Project milestones Appointments Anything coming up Why people choose Days Until: All upcoming dates in one clean vertical list Date-only or timed deadlines Color-code related countdowns Add notes for context Reorder your list manually Mark complete, restore, or duplicate in a tap Delete safely with confirmation No account required Your countdowns stay on your device Simple on purpose. No calendar clutter. No task-manager sprawl. No dashboard noise. No subscription. Just the dates that matter, with the time remaining easy to see.

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.
