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.

Pinlight turns your photo albums into scouting maps. Pick any album from your Photos library and see every geotagged photo pinned to its location — scoped to the album, not your entire library. See not just where you were, but what you shot: • Direction arrows show which way the camera was pointing • A sundial diagram reveals the sun's position at capture time — golden hour, blue hour, harsh midday, or night • Camera, lens, focal length, and altitude extracted automatically from EXIF • Cinema-style color palette strip for each photo • Scene classification describes what's in the shot Filter your map by light condition, favorites, edited photos, or dominant color. Cluster pins for busy locations and browse them in a gallery with swipe navigation. Add your own notes to any photo — parking directions, gear reminders, composition tips — with bullets, bold, and italic formatting. Notes are saved locally and persist across sessions. Everything stays on your device. No accounts, no uploads, no tracking, no analytics. Pinlight reads your Photos library and processes everything on-device. Built for photographers who want to remember not just where they were, but what the light was doing, which lens they used, and why they should come back.

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.
