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

A quick reference manual for the two most popular Hardware Description Languages (HDL): VHDL and Verilog (including SystemVerilog). This app is written by engineers, for engineers. For every construct in VHDL, provides the equivalent in Verilog, and vice-versa. Experienced custom digital logic designer for FPGA or ASIC? Electrical engineering student just learning the ropes? This app is for you. + Searchable dictionary of every keyword, operator, and data type for both languages. + Handbook provides simple example for every single reference + Common functions in each language + All pre-defined attributes for VHDL + All primitive gates and drive strengths for Verilog + Filter by language (VHDL, Verilog, or both) + Filter by language elements (keywords, operators, attributes, data types, etc.)

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.
