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.

Validate with people who use this workflow before building.

Hypothesis 3

Focus on enhancing user interface and experience.

Assumption to check: Poor user reviews regarding usability

Validate with people who use this workflow before building.

Hypothesis 4

Implement a more attractive free trial and clear value proposition for premium features.

Assumption to check: High churn rate from subscription model

Validate with people who use this workflow before building.

App Store description

Sketch 3D is a tool for designing 3D models from your fingertips. You could download models from others, and could also share your great designs with other users by saving models in Public space. New Feature: Integrated MaterialX library into the app.   Mesh object can be applied with materialx documents. When Saving and Loading with material, the document relative path is stored as a diffuse map entry, similar to the way of handling movie textures. Other features like material adjustment and graph editing are not supported yet. User could download free material documents from public websites and import those zip files with this app, using ShareTo or AirDrop. Feature: Use True Depth Camera to capture face model. Feature: Support using video as model texture. You could use video clips from Photo Album, or from Internet URL (YouTube URL not supported), and then apply it onto a model as texture map. Feature: Capture movie from the 3D scene. Note! If your device could not capture movie, then, could try out a smaller output resolution (by tapping the control pane). However, arbitrary output size may stop capturing prematurely. Feature: Design 3D model animation with skeleton structure. You could design a skeleton structure by placing bones in hierarchical relation. Attach model to the skeleton, and then moving the bones to define different poses. Each pose represented as a keyframe in the timeline view. And animation sequence is produced by playing interpolation between the keyframes. Features: - Import 3D content directly from browser or email, either in .zip, .rar, .7z. - Support formats: Collada DAE, OBJ, 3DS, STL(for 3D printing), and others. - Import/export to iCloud drive, via iTune File Sharing, or to Public area via Apple CloudKit Service. - Supports AirDrop. - Support Quad faces. - Smooth surfaces using Subdivision. - Mirroring editing. - 2-fingers vertex movement, 3 or 4-fingers planar shape creation. - Versatile multi-touches drag-through-space gestures to support editing and changing viewing angle at the same time. - Flexible face strip drawing. - Stitching boundary faces. Stitch triangle soap into connected faces. Stitch over edge or vertex to form a larger face. - Stitching Triangles to Quads. - Loop Cut faces. - Bevel edges. - Extrude faces or edges. - Revolve (Spin). - Vertex Smoothing. - Vertex Slide along edges. - Crease Editing after mesh subdivision. - Split mesh from, or Join mesh to the editing one. - Support hierarchical mesh node structure. - Direct vertex color editing when texture map is not used. - Edit texture map UV coordinates, include atlas generation. - 3D Text generation. - Scene interaction with your created shape. - Design Animation with skeleton structure. - Capture movie from the 3D scene. - Support using video as model texture map.

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.
