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

How We Feel is a free app created by scientists, designers, engineers, and therapists to help people better understand their emotions and find strategies to help them navigate their emotions in the moment. Conceived in conjunction with Yale University's Center for Emotional Intelligence and based on the work of Dr Marc Brackett, How We Feel helps people find the right word to describe how they feel while tracking their sleep, exercise, and health trends using HealthKit in order to spot patterns over time. Founded as a science-based nonprofit, How We Feel is made possible by donations from people who are passionate about bringing mental wellbeing to the widest possible audience. Our data privacy terms are clear and easy-to-understand: all of your data is kept on your device unless you opt-in to send an anonymized version of your check-ins to be used in research to help more people. Whether you are downloading this app in order to build better relationships, make your emotions to work for you, not against you, improve how you handle stress and anxiety or simply to feel better, How We Feel will help you identify patterns through daily HealthKit tracking and find emotional regulation strategies that will work for you. The How We Feel friends feature allows you to share how you feel with the people you trust most in real time, strengthening your most important relationships. Filled with step-by-step video strategies you can do in as little as one minute on themes like "Change Your Thinking" to help you address negative thought patterns with cognitive strategies; "Move Your Body" to express and release emotions through movement strategies;"Be Mindful" to gain perspective and minimize the negative impact of misunderstood emotions with mindfulness strategies; "Reach Out" to build intimacy and trust, two important tools for emotional wellbeing, with social strategies.

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.
