Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.

Feature spec

Goal: Send a clear invoice after finishing a job.

  • Add a client, line items, a due date, and payment instructions.
  • Preview the total before exporting a PDF.
  • Keep an editable draft if export fails.

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

SkyBrief — Preflight Weather Briefings for Pilots Honest, complete weather briefings you can trust before every flight. SkyBrief turns raw METAR, TAF, TFR and NOTAM data into a clear go/no-go picture — with no invented values and no guesswork. When a data source is unavailable, SkyBrief tells you plainly instead of filling the gap with made-up numbers. FREE • Live METAR & TAF for any U.S. airport, decoded into plain language • Automatic VFR / MVFR / IFR / LIFR flight category and a go/no-go read • NOTAM digest — active notices grouped by type, closures and restrictions first • Nearby stations, airport directory, and a 24-hour conditions trend • Weight & balance calculator with CG envelope • Flight logbook, currency tracker, and custom checklists • Home Screen widget — your home airport's conditions at a glance • Shareable briefing cards PRO • AI-powered plain-language briefings, with voice read-aloud • Route briefings with real FAA TFRs and true terrain profiles • Winds-aloft nav log and a best-altitude optimizer (compare time & fuel by altitude) • Live radar & satellite overlay on your route • Personal-minimums monitoring with optional push alerts • Kneeboard flight mode, W&B what-if scenarios, and PDF briefing export • Cloud-synced briefing history BUILT ON HONEST DATA Your decisions deserve honest inputs. SkyBrief shows real observations and forecasts from aviationweather.gov and the FAA — and is transparent whenever data is missing or a scan can't complete. ACCESSIBLE Full in-app text-size scaling and high-contrast, readable text in every lighting and sky condition. SkyBrief is a decision-support tool and is not a substitute for an official FAA weather briefing. Always obtain an official briefing before flight. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://skybriefapp.com/privacy.html SkyBrief Pro is an auto-renewable subscription. Monthly and annual plans are available with a 7-day free trial. Payment is charged to your Apple ID account at confirmation of purchase.

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.
