What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

CryptoPad is a system for managing and storing your confidential information: passwords, documents, notes, bank cards, and photos. In CryptoPad: 1) You will never see cloud technologies - data storage in clouds is not secure 2) You will never be able to automatically sync data between devices, because for this it is necessary to use cloud technologies (see item 1). 3) You will never get integration with browsers for automatic substitution of logins and passwords, because we do not decrypt them, our application does not store encryption keys and application password. CryptoPad: - allows you to protect confidential information if you lose your iPhone - stores information in an encrypted zone - protected from hacking over the network - does not store information in the "clouds" - does not interact with other applications CryptoPad is a mobile safe for your sensitive data: - stores your passwords and related information - stores photos and copies of documents in jpeg, png and pdf formats - stores information of your bank cards - stores your notes All data: - stored encrypted - stored only on your iPhone - protected from sending You can: - create new passwords, notes, copies of document and information about of your bank cards, edit them - search - encrypt or decrypt data - create and save the backups - restore data from the backups

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
