A product spec, screen plans, and build steps for your coding agent.

What should your app do differently? Your note travels with the kit so your coding agent builds around your idea.
A product spec, phased build plan, differentiation notes, and screen references.
Illustrative example: an invoice app for independent contractors. Your kit is tailored to the app you choose; this is not its generated content.
Goal: Send a clear invoice after finishing a job.
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.
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.

Discover the language of architecture - the universal vocabulary that reveals how our built environment shapes human experience, influences behavior, and reflects cultural values throughout history. This app has no ads, no account creation, no data collection, no fluff - just straight to the education. Architecture reveals how spatial designs, materials, and structural innovations combine to create environments that impact our psychology, productivity, and wellbeing. These physical elements communicate meaning and function in ways more profound than most realize. This comprehensive reference app equips you with: - In-depth exploration of architectural styles from ancient Classical to contemporary Parametric design - Interactive flashcards to master key terminology and structural concepts - Complete dictionary of architectural terms from "fenestration" to "tensegrity" - Key concepts from master architects including Frank Lloyd Wright, Zaha Hadid, and Le Corbusier - Challenging quizzes to test your architectural knowledge - Convenient cheat sheets for quick reference to essential concepts - Curated hot links to vital architectural resources Part of our Modern Thinking series, Architecture Terms provides essential knowledge for appreciating and analyzing the built environment. Understanding architectural elements, structural systems, and design movements isn't just academic - it transforms how you experience every building you enter and enhances your appreciation of cities worldwide. Equip yourself with architectural literacy. The structures you inhabit aren't arbitrary - they're engineered expressions of culture, technology, and human needs. Shouldn't you understand the language of the spaces that shape your daily life?

Plan a focused first version with your coding agent. These are planning assumptions, not a delivery guarantee.
Choose one audience and one core workflow. Use the kit to agree on its screens, data, and acceptance criteria before building.
Decide which secondary features, integrations, and platform support can wait. Your version does not need to reproduce everything in the original.
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.
