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
Cookie Lens is a Safari extension utility for managing cookies that are accessible on the current site. Use it to inspect cookie names, values, domains, paths, expiration dates, Secure flags, and SameSite settings. You can search the current-site cookie list, create sample cookies, edit common fields, delete individual cookies, or clear the current site's cookies when Safari allows the operation. For debugging and validation workflows, Cookie Lens supports JSON import and export plus Cookie Header string copying. Sensitive operations include clear warnings because exported cookie files and Header strings may contain login sessions or other private data. Cookie Lens is designed for local processing. It does not create an account, does not sync cookie data to a developer-operated cloud service, and does not include advertising, analytics, tracking, login, or payment SDKs. Safari, WebKit, HttpOnly, Secure, SameSite, and site-specific restrictions may prevent some cookies from being visible or editable. Cookie Lens explains those limits and does not bypass browser security protections. Built for web developers, QA engineers, SEO/debugging workflows, and advanced users who need a focused Safari cookie tool on iPhone and iPad.

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.
