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

iCMTGIS PRO is a professional GPS/GIS mapping, data collection and stakeout app for use on the iPad and iPhone devices. It can be used to effectively collect data and increase productivity for utilities, wildlife, natural resources, land management, surveying, soil study, archaeology, drone control points and other land-based or air-borne GPS/GIS applications. LLA, UTM, State Plane and local coordinate systems supported. It also provides the ability to create a local NEZ coordinate system to use with real-world designs on paper. Requires iOS 9 or newer version of iOS. iCMTGIS PRO will work with any iOS compatible GPS devices. In addition, it is able to display the GPS status for a few specific external GPS receivers and record accuracy and quality information for the recorded position - e.g. EOS Arrow Gold, Geneq SXBlue Platinum, Juniper Systems Geod. When used with these GPS receivers, you will be able to set PDOP mask and RMS limit for quality assurance. iCMTGIS PRO can make use of the NGS Geoid12a binary files. It can be a valuable RTK data collection and stakeout tool when used with a compatible GPS receiver that outputs the needed accuracy information. iCMTGIS PRO will let you define a custom Feature-Attribute database to facilitate data collection. It will let you log GPS Points, Lines and Area Features and tag them with predefined or manually added descriptions. It will let you log multiple GPS fixes and automatically calculate the average position. It will let you record nested Points while recording a Line or Area Feature. It will also let you digitize Features on top of a background map or create traverse points by entering angles and distances. You may load a GeoTiff image to use as a static or moving background map. You can record your track while performing other tasks using this app. Enter deed calls to create a deed plot. View distances and areas on the spot. Create buffers. Create a grid over an area. Crate contour lines based on points with (x,y,z) coordinates. Attach photos. Easily import/export Shapefiles, Excel files, DXF files, KML files and text files, send/receive files via ftp or email, and store files in the Cloud. Generate and view PDF files. The app comes with a detailed built-in help document. Free relevant GPS/GIS training videos are provided on the Internet. iCMTGIS PRO provides Point Stakeout as well as Line Stakeout functionality to help you get to a specific Point or to move along a pre-defined Line or perimeter. iCMTGIS PRO is a one-time purchase without any annual subscription fees. It will run on iPad devices as well as iPhone devices. Please note: Location data depends on the GPS receiver used. Continued use of GPS running in the background can dramatically decrease battery life. iCMTGIS PRO will let you easily toggle the GPS on or off.

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.
