Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
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
What fell that night was supposed to be a meteor. A decade later, a blind youth trains, driven by a voice only he can hear. Japan Academy Awards winner Naoki Satō brings the music to a story of unprecedented scale, delivered by an all-star cast as a fully voiced animated comic. Step into the forefront of the comics and manga experience— The World of Cinematic Comics Awaits. *Use of headphones or earphones is recommended for optimal experience. ◆Cast (Japanese Voice Actors) Junya Enoki Mariya Ise Miyu Tomita Chika Anzai Takahiro Sakurai Tomori Kusunoki Sayaka Sembongi Takuya Eguchi Marina Inoue Yuki Ono Show Hayami Shizuka Itoh Yoko Hikasa Yume Miyamoto Koki Uchiyama Shion Wakayama Yoshimasa Hosoya Mamiko Noto Shin-ichiro Miki Yoji Ueda Tomokazu Seki Hikaru Tono Asami Seto Tarusuke Shingaki Kenji Hamada Yasuhiro Mamiya Kosuke Kiminarita Akihiro Tajima Fumiya Imai Naoyuki Shimozuru Mutsuki Iwanaka Jun Yokoyama Shuma Kono Tatsumaru Tachibana Taito Ban Saima Nakano Nene Hieda Mikoi Sasaki Yui Kondo Chiyuki Miura Kanna Nakamura Ami Matsushima Riho Sugiyama Shinichiro Ota Nobutoshi Canna Hiromichi Tezuka Yu Miyazaki Shuichi Uchida Tomoya Ito Shohei Tabuchi Ryosuke Kanemoto Taro Yamaguchi Yoshinori Sonobe Hiroshi Tsuchida Hiroo Sasaki Takaki Otomari Keita Tada Mitsuaki Kanuka ◆Cast (English Voice Actors) Joshua Collins Morgan Cambs David Menkin Janine Harouni Joshua Wichard Jess Nesling Rebecca LaChance Rebecca Hanssen Kosha Engler Holly Earl Rebecca Hayes Samantha Dakin Laurence Bouvard Jules de Jongh Kerry Gooderson Ben Starr Josh Cowdery Joseph May Nathan Nolan Matthew Curtis Stefan Trout Luke Francis Gregg Lowe ◆Music Naoki Satō ◆English Translation & Editing Sean Easley Jeff Hart Kate Nascimento ZigZaGame ◆English Lettering AndWorld Design MediBang!

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.

From the Build Kit assessment.
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.
