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

Highly acclaimed in its four print editions, Bryan A. Garner's Garner's Modern English Usage is now available on your iPhone and iPad. This extraordinary reference tool contains over 8,000 entries and essays that reflect usage lexicography at its finest. Designed with the mobile user in mind, Garner's Modern English Usage is searchable, eminently navigable, and fully citable. GMEU is the liveliest and most compulsively readable reference work for writers of our time. It delights while providing instruction on skillful, persuasive, and vivid prose. Garner liberates English from two extremes: both from the hidebound "purists" who mistakenly believe that split infinitives and sentence-ending prepositions are malfeasances and from the linguistic relativists who believe that whatever people say or write must necessarily be accepted. The judgments here are backed up not just by a lifetime of study but also by an empirical grounding in the largest linguistic corpora ever available. Garner has made extensive use of big data to include ratios of standard terms as compared against variants in modern print sources. No other resource provides as comprehensive, reliable, and empirical a guide to current English usage. If you're concerned with writing and editing, GMEU will prove invaluable to you. Garner illustrates with actual examples, cited with chapter and verse, all the linguistic blunders that modern writers and speakers are prone to, whether in word choice, syntax, phrasing, punctuation, or pronunciation. No matter how knowledgeable you may already be, you're sure to learn from every single entry of this resource. FEATURES * Easy-to-use search tools bring up words effortlessly * Voice search finds what you're looking for without having to type * Text is citable * Favorites feature to create a custom list of words * Usage quizzes test your knowledge with questions written by Bryan Garner

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.
