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

the best surf report / forecasting tool period ... and it's all based on noaa buoy data... ** now available for ipad and iphone ** indicators is the only iphone app that gives you 'spectral energy density' buoy data and makes it easy to understand... so you can truely know if it's firing at your favorite spot... features inclue: - real-time noaa buoy data - 6 hour history noaa buoy data - 7 day forecasted noaa buoy data - real-time noaa buoy data spectral wave energy data collected by offshore buoys is the best indicator of surf conditions in your area. indicators makes it simple to read this wave energy data so you can determine the best swell windows (combinations of swell period and direction) for your favorite breaks. buoys report data every 30 minutes, giving you a much better idea of how much swell is in the water rather than a subjective "cam watching" report. - 6 hour history noaa buoy data too often, swell arrives later than predicted. use the 6-hour history feature to determine if the swell has arrived. if not, go back to bed. - 7 day forecasted noaa buoy data graphically view forecasted buoy data, giving you a better idea of how the swell is changing with time. indicators allows you to: stop wasting time watching surf cams waves come in sets... so if you are watching a cam... are you sure you've watched long enough to see a good set? are you sure you weren't fooled because you saw a rogue set? if you did see a good set... wouldn't you rather be riding it? stop reading reports that only update twice per day who makes these reports? dudes watching cams... (flawed). how often are these updated? twice per day... really? buoy data updates every 30 mintues... (i'd pick this one) know when the surf is good in seconds you only need buoy data... but not just any buoy data... you need swell height, direction and period for each swell. you can use this app to determine the optimal swell direction / period for your favorite breaks...

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.
