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

Continuous is a fast and powerful .NET C# and F# IDE that runs directly on the iPad and iPhone (no network needed!). With it, you can write apps and games using your favorite languages on your favorite devices. Continuous is always building and running your code so you can see changes as you type. Writing interactive apps in Continuous is a pleasure compared to the traditional code-build-run cycle. It frees you to make lots of small changes and see their effects immediately - no more waiting for builds or deployments and no more clicking around trying to get to the screen you're trying to code. Continuous looks and works in many of the same ways as traditional .NET IDEs so you'll feel right at home, but it also strives to advance the state of the art in IDEs with these features: >>> Full C# 8 and F# 4.7 compilers so you can use the latest tech >>> Xamarin.Forms Live XAML Editing >>> Automatic compiling and running so you can focus on the code and the results >>> Fancy text editor with tabs, semantic highlighting, inline error bubbles, and inline values that are updated as you type >>> Watch window enables you to view graphical objects in your app (UI and images), inspect live objects as your app runs, create instances of new objects, and call methods >>> Code completion with inline type info and documentation makes learning new APIs fun >>> Uses standard .NET file and project formats so you can share code with other IDEs >>> Includes Xamarin.Forms and UIKit to build apps and SpriteKit and SceneKit to build games. You can access many iOS APIs including CoreMotion, the Social framework, and HealthKit to read data. >>> Split screen support so you can keep documentation by your side >>> Execution powered by a new IL interpreter If you're new to .NET or iOS coding, you will love the code completion with integrated documentation and the fun examples that come with the app. If you're a .NET pro, then you will love the support for projects and the ability to inspect objects as you code them - whether they're in a script or just a normal project file. If you're new to programming, C# is an great language to learn: it's powerful yet friendly language, example code is all over the internet, and there are plenty of jobs out there waiting for you. If you enjoy thinking a little differently, then you will love that F# is included and fully supported. This amazing programming language will teach you to write better code and will arm you to solve problems that you thought were too big or hard to solve - like writing an IDE.

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.
