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.

Turn any photo into a stencil built to make an impact. StencilStack is made for graffiti writers, street artists, mural makers and anyone who wants to move from phone to paint without spending hours in design software. Take a photo or choose one from your library. For the strongest results, use a clear, well-lit image with one distinct subject, strong contrast and good separation from the background. Choose Standard for more detail or Bold for a harder graphic hit. Cut a quick one-layer stencil or build a full three-layer piece with separate light, shadow and black plates. Preview the finished artwork and inspect every layer before exporting. StencilStack keeps printing practical. Cut areas use thin diagonal hatch lines instead of ink-heavy blocks of solid black, so you can see exactly what needs cutting without draining your printer cartridge. Choose a finished width from 10 to 100 cm in precise 5 cm steps, select A4 or Letter paper and let StencilStack build the print-ready PDF. Make something small on one sheet or scale it across multiple pages for a larger wall piece. Larger stencils come ready to assemble: • 10 mm overlap for a strong join • Clear CUT and GLUE guides • Matching alignment marks on every seam • Page names showing where each sheet belongs • Registration marks that keep all three layers locked together • A clear border that keeps registration marks away from the artwork Print at 100% or Actual Size - never Fit to Page or Scale to Fit. Automatic scaling changes the finished dimensions and can throw out page and layer alignment. Trim the sheets, match the marks, tape everything down and get the cans out. Want the artwork without the cutting? Save the combined image or black Layer 1 directly to Photos. No subscription. No account. No ads or tracking. From a fast single-layer hit to a full multi-page stencil, StencilStack handles the fiddly setup so you can spend more time designing, cutting and spraying.

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.
