Generating… usually about a minute.
What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

ANSI/ASHRAE Standard 62.1-2019, Ventilation for Acceptable Indoor Air Quality, sets minimum ventilation rates and other requirements for commercial and institutional buildings. Standard 62.1 has served the building industry and the public as the most prominent standard on ventilation for indoor air quality. The "HVAC ASHRAE 62.1" iPhone application allows you to perform comprehensive minimum ventilation rate calculations for a wide variety of commercial buildings based upon both the Standard 62.1-2016 and 2019 versions. You can select which version to use by project so as to accommodate LEED requirements and more. This app is loosely based upon the "62MZCalc.xls" Excel spreadsheet that accompanies each copy of the 62.1 User’s Manual (either the 2016 or 2019 version). You can do pretty much everything in this app that you can do in the Excel spreadsheet, in addition to the following: 1. Store an unlimited number of projects, systems, and zones that can be accessed and modified at any time. 2. Quickly perform ventilation calcs in the field, then email the results for further analysis on your office computer. 3. By using slider-controls for the inputs, you can instantly see the results update as you increase or decrease the input values. 4. Access all 70+ ASHRAE 62.1 space types with "per person" and "per unit area" ventilation rates. 5. Create default project templates (with your company default values, for example) that can be used to create new projects. 6. Easily toggle between English (IP) and Metric (SI) units 7. Select to calculate according to the 2016 or 2019 version of the Standard. 8. and more ..... The HVAC ASHRAE 62.1 app comes with full online help. In addition, full support and video tutorials (coming soon) are available at the support link located in iTunes. We will periodically update this app based upon user feedback and will also release new versions along with new versions to the 62.1 Standard, itself.

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
Validate external services, specialist technology, data access, and ongoing costs for your chosen scope.
Not assessed in a Build Kit yet.
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.
