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 Dictionary of Mechanical Engineering, compiled by The CJK Dictionary Institute (CJKI) in Japan, is the only application on any mobile platform that provides comprehensive coverage of mechanical engineering terminology. Do you know how to say "multivariable adaptive control" in Japanese? With this application you can immediately find the equivalent of 多変数適応制御. At home, at work and on the go, translators, students and professionals of mechanical engineering will often encounter technical terms related to machine tools, power generation, industrial equipment and the like for which they need to quickly look up their Japanese or English translations. The Dictionary of Mechanical Engineering, compiled by The CJK Dictionary Institute (CJKI) in Japan, is the only application on any mobile platform that provides comprehensive coverage of mechanical engineering terminology. This application, which provides a user interface in both Japanese and English, includes both English-Japanese and Japanese-English dictionaries that provide access to a total of approximately 210,000 technical terms. While several Japanese-English general vocabulary dictionaries are available for the iPhone, there are few specialized dictionaries that meet the specific needs of professionals, translators and information technology students, while those that are available are prohibitively expensive and of limited coverage. With this application, you get a database of technical terms with extensive coverage at your fingertips for a reasonable price. Please note: This app contains translation equivalents for each term, not explanations of each term's meaning. FEATURES * Both dictionaries combined contain over 210,000 entries * Designed for both English and Japanese users * Covers various subdomains including machine tools, welding, robotics, hydraulics, power generation, and much more * All this data is instantly accessible right on your device - no Internet connection required * What was that word you just looked up? Check the history! * Easy bookmarking puts important terms a tap away * Clean, easy to use interfaces in both English and Japanese ABOUT CJKI The CJK Dictionary Institute is directed by Jack Halpern, editor of the New Japanese-English Character Dictionary and The Kodansha Kanji Learner's Dictionary, now standard reference works. Be sure to check out our other dictionary apps in the CJKI Technical Dictionaries Series, including: Dictionary of IT and Computer Terms Dictionary of Business and Economics Dictionary of Medicine and Life Sciences Dictionary of Chemical Terms Dictionary of Electrical and Electronic Engineering

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.
