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

Verizon Call Filter takes the guesswork out of answering your phone, with features that screen and automatically block incoming spam calls. With Call Filter, you can: • Identify suspected spam calls with alerts. • Automatically block spam based on their risk level and send them to voicemail (Call Filter automatically blocks high-risk callers). • Report phone numbers as spam. • Use filters to block other unwanted callers, such as robocalls. • Adjust spam filter settings any time. For added security, upgrade to Call Filter Plus*. Features such as Caller ID and blocking neighborhoods give you even more control over incoming calls. Download Verizon Call Filter and start answering calls with confidence. *Eligible customers get a 15-day trial for Call Filter Plus. At the end of the trial, customers can choose to subscribe to Call Filter Plus at $3.99 per month, per line. If no action is taken, customers will be auto enrolled in the free version of Call Filter. Accounts with 3 or more eligible lines can subscribe to Call Filter Plus (Multi-line) for $10.99/mo by logging in to My Verizon. The spam filter will be automatically set to block high-risk spam callers, but you can change your block settings at any time. Data charges apply. Verizon's Call Filter App requires a Verizon standard monthly account on an eligible device.

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.
