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

Midnight brings true dark mode to every website you visit in Safari — automatically, instantly, and without the blinding white flash you get from other dark mode extensions. Unlike simple CSS inversion tools that break images and make pages look wrong, Midnight uses intelligent color overrides that preserve readability and visual hierarchy. Text stays crisp, links stay distinguishable, and your content looks the way it should — just darker. FEATURES Instant activation — dark styles inject before the page even renders, so you never see a flash of white Three activation modes — follow your system appearance, stay always on, or toggle manually Smart image handling — choose to dim images slightly, darken them, or leave them untouched Per-site control — exclude specific sites from darkening with one tap from the toolbar popup Unified settings — preferences sync between the app and the extension seamlessly Universal — one purchase works across iPhone, iPad, and Mac BUILT FOR SAFARI Midnight is a native Safari Web Extension, not a port from Chrome. It's built with Swift and WebExtensions APIs specifically for Apple platforms, which means better performance, tighter integration, and full respect for your privacy. No data collection. No analytics. No remote servers. Everything runs locally on your device.

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.
