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.

RainAware, the original hyperlocal rain app with RainClock, push alerts, live radar, satellite, lightning & storm tracking. ***** INCLUDED IN THE STANDARD VERSION ***** • Rain Clock See rain timing for your location up to 3 hours ahead. Example: “Rain starts in 1 hr 30 min and ends at 4:30 PM.” Background images match the weather outside. • Alerts & notifications Get notified when rain is coming or ending, or when severe weather threatens. Customize alert timing, rain-duration thresholds, proximity settings, and alert frequency. • Regional radar, satellite, and 1-hour precipitation View live weather imagery over a regional domain, then move the domain anywhere to inspect weather there. • Watches, warnings, and advisories View active hazards including severe storms, floods, winter weather, wind, fire, marine alerts, and more. • Weather map overlays Analyze the map with overlays for surface observations, lightning, hurricane tracks, storm reports, moving ship observations, and more. • Landscape mode & fast looping Use landscape mode for a larger map with extra pan and zoom controls. Long-press to burst-loop imagery faster and spot trends. • Current conditions ticker Cycles through the nearest surface observation and also shows nearby lightning, precipitation, and storm reports when relevant. Tap icons to jump to the location. • Interactive graphs View 36-hour trend graphs for temperature, wind, cloud cover, precipitation amount and type. • Forecast Clock See the next 8 days in a concise Today/Tonight format, including sunrise, sunset, and moon phase. • Site lists Quickly check weather for nearby cities, airports, ballparks, speedways, golf courses, and more. Stadium views include wind direction for in, out, or across-field awareness. • Drawing tools Draw on the map, add text, overlay it on weather imagery, and share. • Weather badges Badges show when rapid changes in rain, temperature, clouds, or wind are forecast. Configurable. • Deep customization RainAware includes extensive settings so you can tune the app to your workflow. ***** SUBSCRIPTION FEATURES ***** Subscriptions are available in-app and work across supported devices. • Full-map access View the full weather map without regional limits. • Storm cell tracking Filter storm cells and view motion, hail potential, rotation, and more. • National radar products Includes Echo Tops, Hail Swaths, and Rotation Tracks. • Single-site radar Access reflectivity and velocity products, with options to merge Hawaii, Alaska, and Puerto Rico radar into the national view. • Expanded satellite imagery Adds water vapor and colorized visible imagery for enhanced cloud-top analysis. • More alert types Add lightning proximity alerts, severe storm report alerts, and alerts for another location. • RainPro tool Interactively refine precipitation motion for even more precise rain timing. • Environmental fields Display threat areas, VAD wind profiles, isobars, CAPE, updraft helicity, 500 & 850 mb charts & more. • Warning & observation monitor Filter and sort warnings and surface observations. • Advanced surface observations Plot thousands of stations, ships, and buoys, including water temperature and wave height. • Longer loops Animate up to 36 frames and as much as 12 hours ahead on capable devices. • Aviation mode Use FAA sectional maps as an underlay, display flight rules at stations, and view winds aloft at VWP locations. • Advanced drawing tools Draw fronts, time-match drawings to imagery, and create lines, polygons, circles, and squares. • Faster data updates Get more frequent radar, satellite, and surface data refreshes. • Performance controls Manage memory, cache behavior, panning, and image tiling.

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.

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.
