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

Generating… usually about a minute.
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.

[Explore Visual Potential, Embark on a Brain-Eye Coordination Training Journey] This is an auxiliary tool focused on visual perception training, integrating the concepts of neuroplasticity and optometry training logic. Whether you are an office worker who frequently uses your eyes, a teenager in the developmental stage of vision, or an adult who wants to maintain good visual quality, this app can provide you with scientific eye relaxation and visual perception exercise programs. [Core Training Principles and Functions] 1. Gabor Visual Perception Training – Optimizing “Brain Visual Processing” Inspired by the classic Gabor grating principle, it aims to stimulate the brain's visual cortex's ability to process images. Principle: By recognizing specific Gabor patterns, it trains the brain's efficiency in capturing and processing blurred images and high-frequency information. Experience: Assists in improving visual acuity, helping to obtain a clearer perceptual experience in environments with blurred vision or low contrast. 2. Dynamic Visual Tracking – Training Eye Muscle Flexibility Provides multiple interactive exercise modes such as dynamic circles and Schulte squares. **Sagging and Tracking:** Guides regular eye movements, helping to improve the flexibility and coordination of the extraocular muscles. **Focus Exercises:** Combines hand-eye interaction to help improve visual attention and reading fluency. 3. **Accommodation and Convergence Assistance Exercises – Relieving Eye Strain:** Simulates the near-far visual switching mechanism, performing eye yoga. **Eye Muscle Relaxation:** Simulates exercises that switch between near and far objects, helping to break the tension caused by prolonged screen time and relieve eye fatigue and dryness. **Binocular Coordination:** Assists in training the convergence and divergence abilities of the eyes, helping to establish a more comfortable stereoscopic visual experience. **[Suitable Scenarios and Target Audience]** Students/Teenagers: Cultivates scientific eye habits and relieves fatigue caused by prolonged close-up work through accommodation exercises. Office Workers/Screen Users: Targets digital eye strain (DES), helping to relax eye muscles, relieve soreness and dryness, and restore eye comfort. Middle-aged and Elderly Individuals: Maintains visual responsiveness and helps maintain good reading visual quality. For those with specific visual needs: This app serves as a home-based supplementary exercise tool for visual function training, combined with professional advice to optimize vision. Disclaimer: Please consult a professional before using this software. This application is software. The training content provided within the app is only intended as supplementary exercises for eye relaxation and visual perception. It does not have the function of diagnosing, treating, curing, or preventing any eye diseases (such as true myopia, amblyopia, glaucoma, etc.), nor can it replace a doctor's professional treatment plan. True myopia caused by axial elongation is irreversible. If you experience a sudden decrease in vision, eye disease, or severe visual impairment, please be sure to visit a regular hospital's ophthalmology department.

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.
