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.

Assumption to check: Occasional crashes on older devices.

Validate with people who use this workflow before building.

Hypothesis 3

Implement a guided onboarding process.

Assumption to check: Difficult navigation for new users.

Validate with people who use this workflow before building.

Hypothesis 4

Add user forums or discussion boards.

Assumption to check: Lack of community features for sharing or discussing shapes.

App Store description

Decades of steel shapes data. One powerful app. Steel Shapes brings the complete AISC Structural Steel Database to your fingertips - now updated with the latest Version 16 library, rebuilt from the ground up with powerful new features engineers will love. Whether you're on a job site, in the office, or at your desk, every structural shape property from the AISC database is right there when you need it: geometric and mechanical properties, design and detailing values, and instant unit conversion between imperial and metric - all in a fast, clean interface. ---WHAT'S INCLUDED Complete AISC library coverage across every major edition: • Version 16 & 16-SI (latest) • Versions 13 through 15 • LRFD 1st – 3rd Edition • ASD 5th – 9th Edition • Historic shapes ---NEW IN THIS VERSION FILTER BY PROPERTIES Find exactly what you need. Set criteria across any property - weight, depth, moment of inertia, and more - and instantly narrow down the list. Example: "WT or ST sections with weight less than 200 lbs/ft and depth between 10–20 in." BOOKMARKS Build a personal library of frequently used shapes, saved across all editions in one place. SHARE & PRINT Export any section's full property sheet as a PDF - ready to share, attach, or print directly from the app. ---CORE FEATURES UNIT SWITCHING Toggle between English and SI units instantly. Every property updates in one tap. SORTING Rank any shape list by any property - find the lightest W-section or the deepest HSS in seconds. QUICK SEARCH Flexible search that understands how engineers type. "W16 x 89", "W16x89", or "W1689" all find the same section. METRIC EQUIVALENCIES Nearly 2000 shapes with their imperial / metric equivalent designations, one tap away. The most complete AISC reference app available. Visit us at steel-shapes.app

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.
