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

Why not just use an AI assistant to quickly size pipes for natural gas installations? If you prefer fast and consistent results with a familiar user interface, no second-guessing, no trying out different AI models and no subscriptions - this app is for you. #### Pipe sizing and pressure drop calculation for natural gas installations made easy Estimate required pipe diameter for natural gas piping / installations in an instant. Calculate pressure drop for the selected pipe section. #### Obtain required pipe diameter instantly The application provides a quick and simple way to obtain required pipe diameter when designing natural gas piping systems. Only some basic user input is required (heat output and pipe length) and the result is instantaneous and accurate. #### Wide range of conditions The application allows to perform calculations at a wide range of conditions, as gas lower heating value, temperature, pressure and location altitude can be set individually in order to get accurate results. #### Calculate pressure drop easily After a quick estimate of the recommended standard or nominal pipe size, the user can choose their own diameter, customize pipe material and define fittings and valves to calculate volume flow rate, velocity and pressure drop. The app will notify the user if their chosen diameter is too small. #### Metric and Imperial units Natural Gas Pipe Size app can perform calculations using metric or imperial units. #### Features - Provides required pipe diameter for a pipe section in an instant; - Recommended diameter is displayed as a standard DN or nominal NPS; - Gas working pressure and temperature can be specified; - Wide range of working conditions (heat output, pressure and temperature); - Suitable for individual (home) as well as larger, industrial applications; - Different predefined materials can be selected; - Fittings and valves can be selected from the list; - Displays natural gas volume flow rate and pressure drop for selected pipe section; - Suggests whether the selected pipe diameter might be too small; - Metric and imperial units; - No data connection required to perform calculations; - No ads, no in-app purchases; #### Note The application displays results for a pipe section. Calculations for multiple pipe sections should be performed separately. ------ #### Some reviews Natural Gas Pipe Size: pipe sizing & pressure drop calculation for natural gas installations Very helpful natural gas pipe sizing.... I really like this version for sizing natural gas lines. Imperial units are certainly appreciated. Just be sure to reset the fittings section for each section of pipe you checking. 5 stars by Cod Peace | 09 Feb 2016 ---------- Erdgasleitung: Rohr Dimensionierung und Druckverlust-Berechnung für Erdgasanlagen Erdgasleitung Ich benutze diese App sehr viel und immer mit Erfolg. Habe die Angaben oft nachgerechnet und sie stimmten immer. 5 stars by MOMOG62 | 10 Dec 2013

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.
