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
**Stop staring at a blank page. Start building your story.** Story Arc is the ultimate creative companion for novelists, screenwriters, and storytellers. Whether you are crafting a sprawling fantasy epic or a tight, punchy screenplay, Story Arc provides the structural framework you need to keep your narrative on track. **STRUCTURE YOUR SUCCESS** Don't reinvent the wheel. Use industry-proven templates like **The Hero’s Journey, Save the Cat, or the Story Circle** to build a solid foundation. Switch seamlessly between a traditional vertical outline and a modern, visual card-based column view to visualize your narrative flow. **PLAN WITH PRECISION** Whether you're writing a novel or a screenplay, see exactly where your story stands with our **Story Health** engine, which highlights underdeveloped threads, pacing gaps, and missing payoffs. **MASTER YOUR THREADS** Keep your subplots, character arcs, and thematic elements organized. Assign nodes to custom color-coded threads and use our visual development map to see how your subplots weave through your narrative. **KEY FEATURES** - **Flexible Outlining:** Vertical outline mode and horizontal card-based planning. - **Story Health Monitoring:** Detect flat threads, pacing issues, and quiet sections. - **Visual Development:** Track threads and tags with beautiful, interactive visualizations. - **Seamless Sync:** Your work follows you everywhere with iCloud/CloudKit support. - **Multiple Formats:** Built for Prose, Screenplay, and Audio projects. - **Export Ready:** Export to PDF (with Story Map), Markdown, or Plain Text. **DESIGNED FOR FOCUS** Story Arc features a clean, minimal interface that stays out of your way. With native support for iPhone, iPad, and Mac, your entire workspace is always at your fingertips. *Ready to turn your idea into an arc? Download Story Arc today.*

Allow users to choose themes and colors for their story arcs.
Assumption to check: Limited customization options for story arcs
Validate with people who use this workflow before building.
Hypothesis 2
Integrate real-time collaboration for users to work on arcs together.
Assumption to check: No collaboration features
Validate with people who use this workflow before building.
Hypothesis 3
Add features to export story arcs in various formats (PDF, text).
Assumption to check: No export options
Validate with people who use this workflow before building.
Hypothesis 4

Validate with people who use this workflow before building.
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.
