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

Dipsy Troller is an app to interactively get the length of trolling line initially for the Dipsy Troller de Luhr Jensen and some others divers from the same company. As fishermen, we have all opened our fishing box to find that the user data of the divers have been soaked and is unreadable or that we can't find it. It happened to me and to my fishing buddy, so I decided to write this app. The truth is also that to find the right length considering all the factors: the size, the ring, the line, the plates... while driving the boat, putting lines to the water, trying to not hook ourselves, looking at the sonar, trying to get the thermocline depth, adding waypoint when seeing fishes, listening radio for other reports is difficult to say the least. 11 years ago, smartphones were only starting to be in all fishermen pocket but now it is clearly in all pockets.  Dipsies have a very simple data table, while the two values per cell, with or without the ring, make it clearly more difficult to read. But some of the other divers have larger and more complex data tables with tens of columns and rows and even many pages. Now that apps are omnipresent, it was the right time to do another version with more divers.

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.
