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

FlyBox is your personal fly fishing reference and collection manager for iPhone, iPad, and Mac. Comes loaded with 333+ carefully selected fly patterns covering every style of fishing — dry flies, nymphs, euro nymphs, streamers, wet flies, emergers, terrestrials, saltwater, and warmwater patterns. For species including Trout, Bass, Pike, Musky, Carp, Panfish, Bonefish, Permit, Tarpon, Redfish, Steelhead. FIND A FLY: Tell FlyBox where and when you're fishing — region, season, hatch, time of day — and it surfaces the patterns that actually match. Stop guessing what to tie on. FILTER BY TYPE: Instantly filter by Dry, Nymph, Euro Nymph, Streamer, Wet, Emerger, Terrestrial, Saltwater, or Warmwater. Find the right fly in seconds. ADD YOUR OWN FLIES: Add personal patterns with photos, hook sizes, retrieve style, depth, hatch, season, time of day, region, and notes. Your flies sync automatically to all your devices via iCloud. PLAN YOUR TRIPS: Filter by region and season to build the perfect fly selection before you leave home. Sort by rating to see your top producers first. ON THE WATER: FlyBox works completely offline — no cell service needed streamside. Search any field instantly to find what to tie on during an active hatch. ICLOUD SYNC: Your entire fly box syncs automatically across iPhone, iPad, and Mac. Add a fly on one device and it appears on the others within minutes. BUILT BY A FLY FISHERMAN, FOR FLY FISHERMEN: Designed from the ground up by someone who fishes, for people who fish. UNIVERSAL APP: Optimized for iPhone, iPad, and Mac. iPhone uses a clean single-column navigation stack in portrait and switches to a two-pane list-and-detail view when rotated to landscape. iPad uses a true split-screen layout, showing your fly list and detail view side by side. Also available on Mac with Apple Silicon (M1 or later) via the Mac App Store, running in a resizable window with the same split-view layout as iPad.

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.
