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

Grandma's Cookbook is a local-first family recipe keeper for iPhone and iPad. Scan old recipe pages, preserve the original handwriting or clipping, turn each page into a structured recipe card, and cook from it with practical kitchen tools. It is built for church binders, handwritten cards, flour-dusted notebooks, newspaper clippings, and family margin notes that deserve more than a photo album. What you can do: - Scan recipe pages into a named family cookbook volume, or import photos you already took - Turn a scanned page into a structured recipe with ingredients and steps while keeping the original image beside it - Use the Prep Plan to see a readiness score, active time, passive time, make-ahead notes, timed steps, shopping needs, and watch points before cooking - Scale servings up or down and convert cups, tablespoons, grams, ounces, oven temperatures, and common kitchen measures offline - Start Cook Mode for a big-text step-by-step cooking view with timers parsed from the directions - Browse a global Recipe Index organized by category - Build an aisle-grouped shopping list from one recipe or multiple recipes at once - Mark shopping items as already on hand so your buy list stays clean - Log every cooking attempt in the Cook Journal with date, rating, and notes - Export a typeset Keepsake Book PDF with a cover, table of contents, and recipe pages - Correct recognized text when handwriting, smudges, or faded ink need a human pass - Add tags, family notes, and memories to every page - Search across recipe names, ingredients, corrected text, OCR text, and notes On-device text recognition reads printed and clear handwriting. You can edit anything it misses, and the original photo is always preserved. Starter recipes are bundled so you can try scanning workflows, scaling, Cook Mode, shopping lists, Prep Plan, and the keepsake book right away. Grandma's Cookbook keeps everything on the device. There is no account, no analytics, no ads, and no vendor cloud recipe locker. HEIRLOOM BACKUP (NEW IN 2.6) Your shelf is a family treasure - now you can pass it around. Export every volume, family story, hometown, and scanned page into one Heirloom file, send it by AirDrop or email, and anyone in the family can import it into their own copy of the app. Grandma's handwriting, everyone's phone.

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.
