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

Sight-reading skills open the door to reading written music and familiarizing yourself with various music styles. Sight-reading is not a daunting task, and with sufficient practice, anyone can develop this valuable skill. Our app is designed to help you quickly identify notes across every part of the fretboard, with a special focus on positional playing. By enhancing your sight-reading abilities, you'll find it easier to focus on other musical aspects like harmony and rhythm. Features: PRACTICE & TEST MODE - Four different modes of use: 1. Locate notes on the fretboard based on the notes in staff. 2. Locate notes on the fretboard based on note name and pitch. 3. Find the names of notes on the staff (without the fretboard) 4. Identify the names of notes presented on the fretboard. - Automatic detection of problematic notes. KEY SIGNATURES & SCALES - Key signature support, from 1 to 6 sharps or 1 to 6 flats. - Automatic selection of the enharmonic notes for each scale to prevent double sharps or double flats in the key signature. - Scales include major, minor, melodic minor, harmonic minor, blues, pentatonic, and all modal scales. FRETS, STRINGS & NOTE SELECTION - Frets are grouped to limit the number of notes to practice and test. - Predefined fret groups, e.g., 0-3, 4-6, 7-9, 10-12, 0-12, 13-17, etc. - You can define custom fret groups. - The highlighted fret group is displayed on the fretboard. - Your sight-reading progress is tracked per fret group. - The longest streak record per fret group measures your sight-reading accuracy. - You can select specific strings for the highlighted area. - Test notes can be limited to naturals or notes from a selected scale. READ AHEAD - Reading ahead is a crucial skill for effective sight-reading. - You can adjust the number of notes to read ahead. OTHER - More than 15 alternate guitar tunings e.g., drop D, NST (new standard tuning) and all fourths tuning. - Support for left-handed guitars. - Option to display the fretboard in perspective (in landscape mode). - A universal app compatible with iPhone, iPad, and iPod Touch. - Supports all screen sizes. - No ads or in-app purchases. - Dark mode support (iOS 13+). - Tested on iOS and iPadOS 26.

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.
