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
Declutter and refine X/Twitter: hide noise, fix layout, and take back your timeline Fully local · Zero tracking · Zero Ads Feature list: ▸ GENERAL - Classic Bird Branding (bring back the classic bird: logo, favicon, browser-tab title, and "Tweet" wording in place of "X") - Tweet Font Scale [Mobile Only] (enlarge the timeline post text to 100% / 125% / 150% / 200%; menus and the rest of the UI stay the same) - Force Inter Font (apply the clean Inter typeface across the entire X UI) ▸ LAYOUT - Timeline Width (widen the timeline and keep it centered; the left nav and right sidebar dock to the feed's edges and drift outward as it grows, so both stay in view; a slider sets the width up to Max and stays out of the way on narrower windows) ▸ POSTS - Hide Engagement Counts (master toggle with individual controls for reply, repost, like, and follower/following counts) - Hide View Count - Hide Promoted Posts - Hide "Topics to Follow" Suggestions - Hide Post Separators / Borders - Even Action Button Spacing (uniform spacing across post action buttons so bookmark and share are easy to tap) - Edit Share Menu (reorder the items in the post share menu) - Force iOS Share Sheet [Mobile Only] (tap a post's share button to open the native iOS share sheet with the tweet's direct link, instead of X's in-page menu) ▸ TRENDING SIDEBAR - Hide Search Bar - Hide Premium Reminders / Offers - Hide Today's News - Hide What's Happening / Trends - Hide Who to Follow ▸ MENU SIDEBAR - Hide X Logo - Edit Navigation Items (show, hide, and reorder the sidebar nav links) - Edit Bottom Tab Bar [Mobile Only] (show, hide, and reorder the bottom tab bar; Home stays first and always on) - Edit Menu Drawer [Mobile Only] (show, hide, and reorder the slide-out account menu) - Hide Tweet Button - Hide Grok Drawer Button - Hide Chat Drawer Button ▸ SETTINGS - Export / Import (back up and restore your full configuration as a JSON file) - Report an Issue (opens a prefilled support email) The X / TWITTER trademark is owned by X Corp. and used under license.

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.

Intermediate
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.
