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.

Rider inputs every speed change, reset and free time. (new) Reset to Zero: In resets, enter the reset (example) from 32 to 0 In 'speeds' and 'freetime' enter ' 000 0' one one line to separate entries associated with different loops Operation Once all data has been input, Rider clicks on 'GO' tab Prior to start time, the app will countdown to start time. When start time arrives, app begins timekeeping automatically. While on time (within rider minute) display will indicate 'on-time', and display a numeric value 1 - 59 of seconds into riders minute While on time rider will hear (optionally) a single beep every three seconds. When Early (more than 59 seconds ahead of ideal time) display will indicate 'early', and display a numeric value in minutes:seconds of time early When early rider will hear (optionally) a double beep every three seconds. When Late (more than 60 seconds behind ideal time, display will indicate 'late', and display a numeric value in minutes:seconds of time late. When late, there is no audio cue. When On-Time, this portion of the display is green text When Early, this portion of the display is lght blue text When On-Time, this portion of the display is yellow text Whenever it is safe to proceed (not early, not in reset,free time, or approaching possible) 'GO' is displayed in green in upper left As a check is approached, a yellow warning appears in upper left ex: 'Check 12.4' As a check is approached the 'Check Time Seconds' display changes to yellow, as it counts up to the '0' check entry time. When check entry time arrives, yellow 'Check 12.4' changes to green 'GO', and a burst of beeps indicates safe to enter. When Late, the check advisory does not appear, and 'GO' remains in display. When riding on time and a reset or free time mileage is reached, The upper left display will show time remaining at that way-point. Free time and reset countdowns are not displayed when late or early. Mileage can be corrected in 0.1 mile increments with a single swipe of the screen. Each swipe to the right adds .01, each swipe to the left subtracts 0.1. At a check point or gas stop, the next three miles can be cleared of possibles display with a triple tap on the screen. If done in error, use a second triple tap. more info http://www.fpcbaseball.com/checkpointtwo

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.
