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.

FEATURES: - Push Notifications: Get whale notifications in real-time, including species, location, direction of travel, and behaviour. - Real-Time Sighting Reports: Log orca, humpback, grey whale, porpoise, seal, sea lion, and help build a shared picture of whale activity that benefits researchers, conservation groups, and land-based whale watching for the general public. - Live AIS Vessel Tracking: See whale watch boats in real time, with automated detection when vessels are engaged in whale watching activities. - Interactive Map: Street, satellite, and nautical chart layers. Vessel Restricted Zones, voluntary no-go areas, and DFO regulations overlaid. - Sightings Log: Scroll through recent reports from the community with timestamps and species details. - Works With Conservation: Whale Locator provides data to NGOs, First Nations governments, as well as federal, provincial, state and parks enforcement agencies to support marine mammal protection.

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.
