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

Fully cross-platform, vendor-agnostic, Markdown-based note-taking app plus Kanban and whiteboarding tool. You can sync your data with GitHub, your own Git server, or iCloud Drive. Use the power of Markdown to format your notes, and create tables, lists, images, diagrams, etc. Markdown will help to keep your notes in the same style regardless of whether you copied text from the internet or wrote from scratch. Use Kanban boards as a tool to visualize your work and maximize your efficiency. This will help you to organize your time, focus on what matters, and achieve more. If you need quickly visualize your idea, our whiteboarding feature will be handy for you. Add different shapes, make connections between them, add hand-drawn notes, or add reusable elements from the library. KEY FEATURES • Offline-first approach • No vendor lock-in • Periodic sync of data • Fully cross-platform • Different notebook providers: Git, GitHub, iCloud Drive • Seamless GitHub integration • Advanced search • Notes printing • Export notes to PDF • Auto-generated table of contents (TOC) • Kanban boards • Whiteboards (based on Excalidraw) • Dark and light themes (with accent color picker) • Markdown preview with scroll sync • Extended Markdown syntax: Mermaid diagrams, math expressions (MathJax), callouts, ABC musical notation, etc. • Syntax highlighting for code blocks • File attachments • Convert HTML content to Markdown on paste • Editor toolbar with all necessary commands (bold, list, table, etc.) • Markdown syntax guidance • Automatic merge conflict resolution FREQUENTLY ASKED QUESTIONS Q: Why should I write my notes in Markdown? A: Markdown is a widely popular open format with support in many applications. By choosing Markdown you can be confident if you decide to switch to a different application you can easily move all of your data without any conversion needed. Also, Markdown is incredibly easy to understand even in raw view as it's just plain text content with human-readable syntax. Last but not least, Markdown helps you to keep all of your notes in a uniform format, with no more mismatches in font size, font face, etc. when you import data from different sources. Q: What are the benefits of using Git to store notes? A: You will get a lot of things for free: • Unlimited version history, and information on when and who did what changes • Ability to share notebooks with others, you can add anyone as a collaborator or viewer to your Git repository • Easy self-hosting with plenty open open-source options, so notes will truly belong to you • Better merge conflict resolution compared to traditional cloud-based file storage solutions • Ability to create public websites/blogs from your notebooks

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.
