Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
Now all you iPhone-using munchkins can get an unfair, yet completely legal, advantage when you play Munchkin or Munchkin Quest! The Level Counter keeps track of your level (duh). It also rolls a six-sided die (and doesn't cheat). But best of all . . . once per game, you get a Boon . . . an in-game advantage to help you kill the monsters, steal the treasure, and stab your buddy. There are almost 150 different Boons, all illustrated by John Kovalic. The higher your level when you ask for your Boon, the better it's likely to be. And when you reach the winning level, it plays a fanfare. Your friends will hate you . . . Bonus features include: • Kill-O-Meter screen to keep track of combat scores. • Counters for Chez Geek and SPANC (Space Pirate Amazon Ninja Catgirls) illustrated with art from the games. This app is NOT a stand-alone game! It is a game aid for the Munchkin card games and Munchkin Quest board games by Steve Jackson Games. Munchkin is the dungeon experience . . . with none of that stupid roleplaying stuff. Visit http://www.worldofmunchkin.com/ to find out more about Munchkin!

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.

From the Build Kit assessment.
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.
