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.

Freevening is a wellbeing-first calendar app. Instead of asking "what evenings are open?" which is how overcommitment sneaks in — it tells you which evenings must stay free to protect your weekly rest, and which ones still have room for plans. What it does • Reads your existing calendar — no new accounts, no syncing. • Color-codes each evening: green if you can still schedule, yellow if it must be rest, red if it's booked • Sets a weekly rest target you can actually defend • Shows when your next truly free evening is, in plain English ("in 2w 3d") • A Plan tab to lay out your recurring commitments against the year and see how packed it really is • Tap any event to jump straight to it in Google Calendar • Home screen widget for an at-a-glance check Built for one specific problem You can see every empty slot in your calendar, so you fill them. A month later you're spread thin, burnt out, and skipping the things that actually recharge you — workouts, hobbies, deep conversations, sleep. Freevening flips the framing: free evenings aren't inventory to fill. They're the floor you need to keep above. The app reads your calendar so you can stop trying to mental-math your way through it.

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.
